NOTE ON ORYSSUS SAYI
Authors: Harrington W. Hague
Published: February 2010

The members of the genus Oryssus are appareutly rare in Canada, and I was therefore much pleased to capture on the 2nd June a fine ♀ O. sayi. It was running up and down a telegraph pole (one of the new ones put up for the electric light wires), and had at first glance all the appearance of some small wasp (Crabrolidæ), searching for a suitable hole for its nest. Its movements were very quick, and its antennæ vibrated rapidly. It was so alert and restless that my prospects of capturing it without a net seemed far from bright. However, the capture was made, and its struggles in my cyanide bottle were brief. A few days later I took a ♂ upon one of the same poles, although in a different part of the city, and saw what appeared to be another of these insects fly away from higher up the pole. On the 24th I secured another female, which was even more active than the first, and which flew away and returned to the same place twice before I effected its capture. This habit of flying away when disturbed and of returning, even from some distance, to the very spot left, is one which I have noticed in other species of Uroceridæ.
THE ENTOMOLOGY OF VANCOUVER ISLAND.: NOTES ON SEVENTY-SIX SPECIES OF CICINDELIDÆ AND CARABIDÆ COLLECTED NEAR VICTORIA, VANCOUVER ISLAND
Authors: Taylor George W.
Published: February 2010

The beetles enumerated below were all taken by myself in the neighbourhood of Victoria, Vancouver Island, during the past few seasons. Some of the larger species, especially the Colosomas, were captured under heaps of rubbish in my garden. The species of Omus and Cychrus and many others were found while searching for land shells under oak logs in the woods. Very many kinds too were found under stones, also during search for shells, while most of the rarer kinds were taken, accidentally I might say, while flying in the sunshine.

The number of specimens of Carabidae that could be collected here is very large, individuals being in fact far more numerous than I have ever seen them anywhere else, and I feel confident that a season's careful working would almost double my present list of species.
NOTES ON AN INJURIOUS SAW-FLY LARVA
Authors: Fyles Thos. W.
Published: February 2010

Length of larva, one and one-eighth inches; breadth at widest part, three-sixteenths of an inch. The body flattened beneath, and slightly rounded above. It is scalloped along the sides. The legs proper are long and projecting. The creature has the habit of twisting the last four or five segments to one side. When disturbed it throws itself into the usual attitude of a Nematus larva. Its general color is yellow—the head has an orange tinge. There are ten rows of black spots on the body—six rows along the back, one row on each side, and two rows underneath. The spots of the side rows are longer than the rest, and are placed olre on the fore part of each scallop. In each of the rows on the back the spots run three to a segment. The last segment has no spots. The eyes of the larva are black, and the mandibles are brown. The creature forms a rather loose, white cocoon.
ON PHYSONOTA UNIPUNCTATA Say, AND ITS SUPPOSED VARIETIES
Authors: Caulfeild F. B.
Published: February 2010

As considerable doubt appears to exist with regard to the three species or races of Physonota described by say, Randall, and Walsh and Riley, and as I had in former years found a species of this genus to be rather common in the vicinity of Montreal, I endeavored during the past season to find it again, and, as far as my opportunities would permit, work up its life history.

Early in May I made a careful search in the locality where I had previously found it, but at this date its food plant had not yet appeared above ground. I tried again in June, the time at which I had formerly taken the first brood.
NOTES ON CERESA BUBALUS, Say
Authors: Jack John G.
Published: February 2010

Read before the Montreal Branch Ent. Soc. of Ont., 9th Feb., 1886.

During the past two years, but more especially this season, we have been very much troubled and annoyed by the attacks of the Buffalo Treehopper (C. bubalus Say) on the young trees in the orchard. Most of the trees have been seriously injured by having the bark cut up by the ovipositors of these insects, when depositing their eggs. These incisions and the eggs in them were so numerous that in many cases it was impossible to raise the bark for the purpose of “budding” the trees.
THE COLIAS CONTROVERSY
Authors: Stretch R. H.
Published: February 2010

It is to me a most distasteful task to take part publicly in the “Colias” controversy between Mr. Edwards and Dr. Hagen, as I was an invited guest of Dr. Hagen on the trip to Washington Territory, where the events took place which have given rise to the discussion; but in the interest of science, which seeks nothing but the truth, it seems as though the time had come when I ought to state in a concise manner what I know of the whole matter. I have been cut off from all my books for the last five months, while travelling from place to place, or this letter would have been written earlier. I did not know till quite recently the phase to which the controversy had arrived. Probably the best thing I can do is to state the manner in which our party was organized, and the manner in which our collecting was done.

The party consisted of Dr. Hagen, and his assistant, Samuel Henshaw. In San Francisco I was invited to join it, and did so.
DESCRIPTION OF A NEW CHALCID, PARASITIC ON MANTIS CAROLINA, Say
Authors: Ashmead Wm. H.
Published: February 2010

Podagrion mantis, n. sp.

♀. Length .15 inch; ovip., .14 inch. Dull metallic green, finely punctate and sparsely covered with short, whitish pubescence; antennæ and legs dull yellow; flagellum brownish above, all coxæ metallic green, sculptured, posterior ones large, tips of feet black. The posterior femora are greatly swollen as in the Chalcidinæ, armed with about eight large teeth, brown at sides but brassy along upper surface, pubescent, tibiæ greatly curved; abdomen metallic green variegated with brown, compressed and shaped as in the ichneumon genus Ophion; wings hyaline, veins brown, marginal and post-marginal veins long, stigmal vein short, thick.

Described from one female specimen bred from egg mass of Mantis carolina Say. This is an interesting discovery, and the first species of the genus to be described in our fauna.
ON THE PROBABLE FOOD OF THE LARVA OF SCENOPINUS
Authors: Hagen H. A.
Published: February 2010

Prof. F. W. Putnam communicated to me a larva of Scenopinus found in his house under a carpet. It belongs very probably to Sc. pallipes Say, which was reared by Mr. Sanborn out of larva found under a carpet. The larva is figured by Prof. A. S. packard, Guide, p. 1 and 401, and Proc. Essex Just., October, 1867, p. 94, where three other larvae found under the carpet are mentioned. There are three European species reared. Sc. senilis (Bouché Naturg. Ins., p. 46) is said to live in rotten fungus on willows and other trees. Sc. fenestralis (Assman Stett. Ent. Z. 1863, p. 400) in over-ripe strawberries; but it has been later suggested that it may belong to another species. Frauenfeld (Verh. zool. Bot. Ges. Wien. 1864, vol. xiv) has reared Sc. fenestralis from larvae found in a horse hair mattress. Prof. Loew records the larvae living in a swallow's nest. Mr. Perris (Ann. Soc. Ent. Fr. 1870, vol. x., p. 230) tells that Dr. Cartereau found in a swallow's nest a pupa of Lucilia dispar containing an imago of Sc. fenestralis which had not been able to leave the pupa of Lucilia, so the larva must have fed on it.
MONOGRAPH OF THE LOMATINA OF NORTH AMERICA
Authors: Coquillett D. W.
Published: February 2010

The Lomatina may easily be distinguished from the other Bombylidæ by the following characters:

Front very large; antennæ shorter than the head, the third joint at least twice as long as the first, taperirg to the tip, or suddenly contracted near its base, the terminal portion styliform; terminal style minute. Proboscis never projecting more than one half its length beyond the hyperstoma. Front and face when viewed from the side form a gentle curve, never greatly produced at base of antennæ. Wings with two submarginal and four posterior cells; furcation of the second and third veins occurs before the small cross-vein at a distance of at least twice the length of that cross-vein. All of the tibiae bristly.
LARVA OF COELODASYS MUSTELINA, Pack
Authors: French G. H.
Published: February 2010

Length .80 of an inch. Head oblique, narrow, slightly bilobed, about one-fourth of the head above the height of joint 2; body nearly cylindrical; on joint 5 a nearly conical projection about two-thirds as high as the depth of the body, bifid at the top, each part tipped with a hair; on joint 9 is a slight elevation, and a more prominent one on joint 12. When at rest the posterior part of the body is raised, making these elevations appear more prominent. In color, the head, joint 2, and the dorsum of joints 3 and 4 to the top of the tubercle on joint 5, is dark brownish purple mottled with gray, the sides being lighter than the front of the head and the dorsum, the latter narrow posteriorly; the sides of joints 3 and 4 are bright green with a few fine purple dots and a pale dorsal edging; the sides of the body back of joint 4 are a series of fine, close, crenate purplish red lines or mottlings on a grayish yellow ground color, more yellow above, giving the sides something of an orange appearance; the dorsum of joints 5 to 8 is more of a grayish color from the ground color being paler and the mottlings finer and more of a purple shade; a darker patch on the dorsum of joint 8, this color extending back obliquely on joints 9 and 10, making a dark purple lateral line; the pale part of the dorsum is wider on the posterior than on the anterior of each joint, the space being boldered by an oblique purpte line that fades out before quite reaching the lateral line; the rest of the dorsum is like the sides, except a little darker I between the two posterior tubercles or elevations is a clear white V, the point beginning on the anterior part of joint 10 and extending back to the posterior part of joint 11 on the sides.
A NEW CHALCID PARASITE ON THE COMMON BASKET WORM (Thyridopteryx ephemerœformis Haworth)
Authors: Ashmead Wm. H.
Published: February 2010

This peculiar moth, which so perplexed the older Lepidopterists at classifying, is quite common in Florida on oaks, willows, shrubs, etc.

Full accounts of its habits, with accurate figures of the moth, caterpillar, etc., will be found in Prof. Riley's “First Mo. Report,” Saunders' “Insects Injurious to Fruits,” and Dr. Lintner's “First N. Y. Report.”

Indeed, these authors quite fully, accurately and succinctly describe the habits and parasites of this pest, and it would not now be noticed by me but for the fact of my breeding from it here in Florida a Chalcid parasite new to science and unnoticed by any of the above mentioned authors.
AN EXPLANATION
Authors: Saunders W. M.
Published: February 2010

A protracted absence from home has prevented me from offering earlier to readers of The Canadian Entomologist an explanation of the circumstances which have led to my resignation of the post I have held so long as Editor of this journal. For thirteen years it has been my pleasure and privilege to be thus brought in contact with most of the active workers in the Entomological field, with many of whom I have held pleasant intercourse both by correspondence and in person, and it occasioned me much regret when I found it necessary to sever my connection with those editorial duties which had hitherto given me so much pleasure.
SYNONYMY IN AMERICAN COLEOPTEROLOGY
Authors: Hamilton John
Published: February 2010

On looking over Melsheimer's Crotch's and Henshaw's Catalogues of the described species of North American Coleoptera, many names will be seen placed as synonymical, or varietal; while a reference to the bibliography of the many synopses and monographs of families and genera in the Trans. Am. Ent. Soc., and other publications, exhibits a number still larger.
NOTE ON ABBOT'S SPECIES IN THE BREMEN MUSEUM
Authors: Grote A. R.
Published: February 2010

In the Bremen Museum are specimens collected by Norwich in the Souther States in the beginning of the country, which bear evidence of having been determined by Abbot, as there are one or two MS. names credited to him. I note here merely a ♀ specimen of Parorgyia leucopheœa; this is paler, the outer line followed by brown shadings, as compared with our Northern Clintonii, and agrees with a specimen collected by myself in Alabama, and previously described in Can, Ent.
FOSSIL BUTTERFLY FOR SALE

In order to illustrate more fully his forthcoming work on New England Butterflies, the undersigned offers for sale for Two Hundred and Fifty Dollars, that wonderfully preserved Fossil Butterfly, Prodryas Persephone, of Colorado. The accompanying cut gives a rude impression of it. Less than twenty specimens of fossil butterflies are known in the world, and this is by far the most perfect and best preserved.
ABOUT NAMES
Authors: Grote A. R.
Published: February 2010

I have read, as all of us have, the review of a book by C.J. Maynard, on our Butterflies, by Mr. W. H. Edwards, and which appeared in the February number of the Canadian Entomologist. Whatever Mr. Edwards writes in trenchant and to the point, so that we have received the impression that Mr. Maynard's book is really not what it ought to be, is not up to current scientific knowledge, and is inferior in its illustrations. There is no more to be said about the book on this head; its publication will probably do very little real good, except perhaps that here and there a reader into whose hands it may chance to fall may have his interest excited in the subject, and so be led to buy a better one, as, for instance, that of Prof. French, to say nothing of Mr. Edward's splendis volumes.
STUDIES OF THE NORTH AMERICAN PROCTOTRUPIDÆ, WITH DESCRIPTIONS OF NEW SPECIES FROM FLORIDA
Authors: Ashmead William. H.
Published: February 2010

In this second paper on the North American Proctotrupidœ, I have taken up the sub-family Platygasterinœ, comprising, for the most part, small black species, all parasitic in larvæxs belonging to the Dipterous families Cecidomyiidœ and Tipulidœ.

It will be seen that I have recognized in our fauna species in all of the described genera but Iphetrachelus Haliday, and one new genus parasitic on Cecidomyious hickory galls.
ALETIA ARGILLACEA
Authors: Grote A. R.
Published: February 2010

I have found in various collecitons in Europe, both public and private, specimens of the moth of our Cotton Worm determined after Hübner as above. From a note from Dr. Staudinger, I gather that in his collectin the moth is so determined and as proposed by me. Were I now to propose to call this species by its synonym, Noctua xylina Say, I do not think any of the entomologists in Europe would agree thereto, or be governed by Dr. Hagen's reasons for the change.

Length of body, male, with app., 50 mm.; female,45. Length with wings 65 mm. Exp. al., 118 to 120.

Very similar in shape and color to A. Americana. After long consideration I beliver them to be different species, until by a larger material it shall be shown that the differences given are such that A.Texana shoudl be considered to be only a well marked variety.
THE CLASSIFICATION OF THE BOMBYCIDÆ
Authors: Grote A. R.
Published: February 2010

Notwithstanding much that has been learnedly written upon the family Bombycidæ, or Spinner Moths, no strong exclusive structural characters have been brought to light which hold the groups together as a natural family. Following Linné and Latreille, the American authors, Dr. Harris and Dr. Packard, have, however, considered such a family to exist. In Germany the different groups, or sub-families, have been raised to the rank of families, while under the loose term Bombyces the Spinner Moths as a whole have been designated.
SOME NORTH AMERICAN TACHINÆ
Authors: Sacken Baron Osten
Published: February 2010

Tachina (Exorista) futilis Say., MSS. ♂, ♀. Palpi, antennæ and legs black; face, front and lst abdominal segment with a brassy-yellow reflection. Length, 7–10 mm.

Bottom of the antennal foveæ silvery gray; the lowr part of the cheeks likewise; front, lateral parts of the face and the orbit of the eyes below and behind (genal and occiptial orbit) brassy-yellowish, the coloring of the front being of a more saturate yellow than the lateral parts of the face; above the antennæ, in the middle of the front, a brown stripe, attenuated posteriorly; it bifurcates on the vertex, enclosing the grayish ocellar triangle; the hind plane of the head (occiput) gray. The row of frontal bristles consists; 1st, of three bristles pointing backwards, the uppermost of which is placed on the top of the vertex; 2nd, of three shorter bristles pointing forward; 3rd, of four or five bristles which form diverging rows, descending on both sides of the antennæ, the last being a little below the end of the second antennal joint.
SOME NOTES ON THE GENUS COLIAS WHILST ALIVE IN THE IMAGO STATE
Authors: Geddes Gamble
Published: February 2010

The paper which I have prepared to read upon the genus Colias differs from any that I have consulted up to the present time, in that it treats principally of the habits of the different species during lifetime in the imago state.

During the last ten years giganitc strides have been made by lepidopterologists in breeding the different species of this perplexing family, and their efforts have been crowned with such succes that only a few remain about which nothing is known of the primary stages. It is about the life habits in the prefect state of someof these that I propose to address you, and if my paper does no good, it certainly cannot do any harm, as you will see by the subjoined list of my captures of the different species of Coliadæ that I have a right to express an opinion in this particular direction.
ON SO-CALLED REPRESENTATIVE SPECIES
Authors: Grote A. R.
Published: February 2010

The species of our insects having near allies in the better known or earlier known European fauna, have called “representative” by the elder Agassiz. And this term would be sufficiently exact and useful did we not associate with it the somewhat metaphysical sense, that these forms were separately created and owe their resemblance to the arbitrary will of the Creator.
ON THE GENERA ALLIED TO HOMOPTERA
Authors: Grote A. R.
Published: February 2010

I have (Can. Ent., vol, xv.) shown the different structure of the tibiæ in the genera o N. Am. Noctuidœ allied to Homoptera Boisd. But sometime previously I pointed out that this name was used for a section of Hemiptera, and that for this and other reasons we should probably be thrown back upon Pheocyma of Hübner.

FURTHER INJURY TO LIVING PLANTS BY WHITE ANTS
Authors: Scudder Samuel. H.
Published: February 2010

More than twenty-five years since (Proc. Boston Soc. Nat. Hist., v.7, p. 287–288) I published an account of serious injury to living grape-vines in hot-houses in Salem, Mass., by our common species of whit ants. Termes flavipes. No further notice of their injury to living vetetation appears to have been taken unitl a few years ago, when Prof. J. H. Commstock, then government entomologist, state ( Rep. Comm. Agric., 1879, 207–8) that they had been found in Texas and Florida “girdling the bark of orange trees and guava bushes near the surface of the ground, or eating out the interior of sugar-cane and other plants.”
ON COLIAS ERIPHYLE Edw., AND C. HAGENII Edw
Authors: Edwards W. H.
Published: February 2010

In my last paper I showed that C. Hagenii was a yellow form of C. Eurytheme Bois., and I am now prepared to say that Hagenii is identical with Eriphyle, and the name gives way to this. I described Eriphyle, Tr. Am. Ent. Soc., v., 202, 1876, from about thirty individuals of both sexes, taken in British Columbia, at Lake Lahache, by the late G. R. Crotch; and related that they were submitted to Mr. Henry Edwards, who pronounced them distinct from any of the Pacific coast species, an opinion with which I agreed.
NOTES ON CALLIMORPHA
Authors: Smith John. B.
Published: February 2010

In the early spring of 1887, while arranging the National Museum collection of Arctiidœ, I tried to make out the varieties of Callomorphalecontei listed in our catalogues, and soon came to the conclusion that we had to do with more species than were generally accepted. I investigated the literature of the subject and prepared a paper, the results of which were first communicated to the Entomological Society of Washington at their March meeting (see Entom. Americ., iii., p.20).

NOTES ON THE LOCUSTIDÆ, WITH DESCRIPTION OF A NEW SPECIES
Authors: Davis Wm. T.
Published: February 2010

Whether they fill the listener with a train of happy thoughts, as Gilbert White says, or whether they produce a sadness because the days of summer are nearly gone, as Dr. Harris asserts, the songs of crickets and other Orthoptera have, nevertheless, the merit of always being interesting. An insect that can sing—that has something to say—even though it be the same, night after night, enjoys a sort of individuality, and this lon discussion of the Katydids and the quiet murmur of the tree crickets, constitute one of the chief charms of our summer evenings.
DISSOSTEIRA CAROLINA

Published: February 2010

During the past summer I collected at Dublin, Wayne Co., Ind., a number of Œdipodini that seem to be a long-winged variety of the above named species. A comparison of the dimensions given by Thomas and Saussure for D. carolina and D. longipennis with measurements taken from eleven of these specimens, will show what the difference amounts to.
THE COCCIDÆ IN THE MUSEUM OF COMPARATIVE ZOOLOGY, CAMBRIDGE, MASS
Authors: Hagen H. A.
Published: February 2010

Having newly arranged the Coccidæ of our collection, which have been named by Prof. J.H. Comstock, I compared them with the professor's Catalogue for 1883, and ascertained the presence of two-thrids of the 168 numbers enumerated. I find that only 27 N. Amer. species are wanting. Among the insects received in the collection of the Peabody Academy is Lecanium tiliœ, A. Fitch, from Mt. Carroll, Ill., by Mr. Shimer, very probably identical with A. Fitch's species, and Lecanium tulipiferœ, Cook, by typical specimens.
THE LARVA OF LIPHYRA BRASSOLIS PROBABLY APHIDIVOROUS
Authors: Holland W. J.
Published: February 2010

Some two years ago I received from Rev. L. C. Biggs, H.B.M. Chaplain at Penang, a parcel of insects collected by Mr. F. G. Durnford in Sungei-Ujong. Among them was a speciment the envelope containing which was labelled Charaxes Durnfordi, n. sp. Mr.Biggs, in sending the lot, called attention to this particular specimen in his note, saying: “It looks as if it were covered with mildew, which Durnford assures me is really fluff detached at the time of its capture.” I did not examine the specimen ver particularly at the time of its receipt, except to note that it was covered with a whitish mealy deposit, particularly thick upon the abdomen, and that it was not a Charaxes.
ON HEMARIS DIFFINIS, Boisd
Authors: Grote A. R.
Published: February 2010

In my own collection I labelled a form in which a slight dentation of the terminal band on primaries was perceptible (and which in this respect agreed with Boisduval's figure in the Species General, and with Abbot's of fuciformis) as H. diffinis. It differed from tenuis by a greater breadth of band, a perceptible apical stain, a somewhat brighter or ore yellow haired body. Whether this was Mr. Strecker's Aettira, I Knew not, since I was unacquainted with this author's work, having seen only his numbers on occasion.
FURTHER ADDITIONS TO THE LIST OF CANADIAN MICRO-LEPIDOPTERA

Last season being but a poor one for the Lepidopterist in this locality, I got but little that was new to me in this department. Being in communication with Prof. Fernald about the few I had in duplicate, I proposed to send all my single specimens to him, to name what he could and return them to me again. The professor most generously consented to the very exacting conditions, and returned my insects, which made the double journey by express, without a break, accompanied with the following names:-
TINEINA
Authors: Chambers V. T.
Published: February 2010

I am but imperfectly acquainted with this genus, knowing it only through the Nat. Hist. Tin,, vol. xi. ; andl the plan of that work does not seem to admit of details of structure. If it is equivalent to Aechmia, Perittia, Tinagma and Douglassia combined, as those genera are limited in Ins. Brit., v. 3, then the proper place for this species is in it. But if, as I conclude from the account in Nat. Hist. Tin.. it is the equivalent of Tinagma alone, and the other groups above mentioned are good, distinct genera, then this species, while possessing affinities with all, would be out of place in either.

The usual black band behind the eye broad and distinct, and reaching last division of pronotum, bounded below by a narrower white stripe. A broad white stripe from base of elytra connects with a white stripe at insertion of posterior femora, forming a right angle. Outside of hind femora is crossed by two indistinct dusky bands that extend upon upper edge. Lorver sulcation reddish. Knees black. Hind tibiæ blue. Elytra light brown with very small black spots in the disk.
NOTES ON LARVÆ—FONDNESS FOR WATER—HINTS TO BEGINNERS
Authors: Siewers C. G.
Published: February 2010

Last spring, while collecting beetles under the bark of decayed logs, I met with numbers of the larvæ of Arctia isabella (hairs brown in the middle, black at each end of larva,) about to spin up. Not knowing their hybernating habits, they had always baffled me, and under the impression that they would require another season to mature, had been turned loose. I collected some twenty, put them into a box with cotton and paper scrap, and they at once spun up, all but four. These wandered up and down for a week, having some want, and wasting away.
ON THE PREPARATORY STAGES OF SATYRUS NEPHELE
Authors: Edwards W. H.
Published: February 2010

I have tried for several years past to raise larvæ of Satyrus nephele to maturity, but met with no success till this last spring. It is very easy to obtain the eggs by confining the female with a tuft of grass. I tied a gauze bag on such a tuft set in a flower pot, while in the Catskills, and 21st August, 1876, obtained perhaps fifty eggs. Some were laid on the blades and stems of the grass, but many were dropped loose on the ground. The eggs hatched about the 21st of September, and the young larvæ without feeding entered upon their hybernation.
ON THE HABITS OF AMBLYCHILA CYLINDRIFORMIS
Authors: Williston S. W.
Published: February 2010

The greta interest in which this beetle has been held by Entomologists for so long has renderes an accurate account of its habits very desirable ; but for a very long period–over twenty years–it has singularly eluded more experienced observers. In the Proceedings of the Kansas Academy of Science for 1876, a slight account was published by Mr. H.A. Brous, but from the very small number taken by him, his article was necessarily imperfect.
NOTES ON SOME SPECIES OF HOMOPTERA
Authors: Bean Thos. E.
Published: February 2010

The suggestion of Mr. Hill (quoted on p. 89) that Homopteras “edusa and lunata are possibly sexes of one species,” has reminded me of my own doubts regarding not only edusa and lunata, but also Saundersii, and caused me to make a careful examination of my material.

My entire stock numbers 83 local specimens, arranged after authentic types in three series, consisting of 42 “lunata,” 24 “Saundersii,” and 17 “edusa.”.

The specimens separated as lunata show no white lines or areas on upper side of wings.
PIERIS VERNALIS A VARIETY OF PIERIS PROTODICE
Authors: Bean Thos. E.
Published: February 2010

Experiments and observations during 1874–5, supplemented by comparison of a large suite of specimens, seemed to invalidate the specific separation of vernalis. Submitting the facts to Mr. W. H. Edwards, he confirmed my opinion, and in the recently issued “Catalogue of the Diurnal Lepidoptera of America North of Mexico,” he has placed “vernalis” as a variety of P. protodice.

CATOCALÆ TAKEN AT SUGAR AT CENTER, N. Y
Authors: Bailey James S.
Published: February 2010

The following list will show the order in which Catocalæ were taken during July and August, 1877, at sugar, and the number taken each day of each variety, in this particular locality. Center has proven itself rich in Diurnals, and now especially so in catocalæ. It is singular, after working up the field thoroughly for several years, not a vestige of a catocala has before this year been seen by the writer. In fact their presence was doubted, until this season a caterpillar was seen.

I have received from Canada (London, Mr. Saunders) a nerv and easily recognizable species of Nola,larger than ovilla, and in describing it, I have again gone over the characters of Argyrophyes, which I find to be allied to Nola, and not to belong to the Geometridæ. I have corrected my former observations on Argyrophyes, which I find to have been largely erroneous.

TINEINA FROM TEXAS
Authors: Chambers V. T.
Published: February 2010

My knowledge of this genus is derived wholly from Prof. Zeller's paper. It is equal in part at least to Holcocera Clem. (I have to thank Prof. Riley for calling my attention to the fact that in some of my references to this genus the name is incorrectly given as Holocera.)

B. sciaphilella., as described and figured, differs from H. triangularella Cham. as to the position, size and form of the triangular spots on the wings. Sciaphilella has distinct opposite, comparatively small costal and dorsal triangles, while triangularella has no dorsal triangle, but a single large costal one, wide upon the costa and crossing the fold, and it also has the apical part of the wing distinctly streaked and clouded with brownish gray.

ON THE LARVAL CHARACTERISTICS OF CORYDALUS AND CHAULIODES AND ON THE DEVELOPMENT OF CORYDALUS CORNUTUS
Authors: Riley Chas. V.
Published: February 2010

The paper relates to the development of one of the most singular and interesting of North American insects–the largest of the Order Neuroptera. In its perfect state this insect is a great, clumsy, nocturnal fly, popularly called Hellgrammite, and charecterized by the jaws of the male being converted into a pair of long, curved, cylindrical and tapering prehensile organs, like the finger of a grain-cradle. In the larva state it is aquatic and much esteemed as fish-bait by fishermen, who call it a “crawler,” “dobson,” etc. Indeed, one of the most popular artificial fish-baits is a patent india-rubber imitation of it.

IL-15 is required for NK cell development and homeostasis in vivo. Because IL-15 is presented in trans via its high-affinity IL-15Rα–chain to cells expressing the IL-15Rβγ complex, we postulated that certain IL-15–bearing cells must be required for NK cell homeostasis. Using IL-15WT/WT and IL-15−/− mice, bone marrow chimeras with normal cellularity, and a selective depletion of CD11chi dendritic cells (DCs), we demonstrate that ablation of the resting CD11chi DC population results in a highly significant decrease in the absolute number of mature NK cells. In contrast, administration of Flt3 ligand increases the CD11chi DC population, which, when expressing IL-15, significantly expands mature NK cells via enhanced survival and proliferation. In summary, a CD11chi DC population expressing IL-15 is required to maintain NK cell homeostasis under conditions of normal cellularity and also is required to mediate Flt3 ligand-induced NK cell expansion in vivo.

Visualizing oncogene/tumor Ag expression by noninvasive imaging is of great interest for understanding processes of tumor development and therapy. We established transgenic (Tg) mice conditionally expressing a fusion protein of the SV40 large T Ag and luciferase (TagLuc) that allows monitoring of oncogene/tumor Ag expression by bioluminescent imaging upon Cre recombinase-mediated activation. Independent of Cre-mediated recombination, the TagLuc gene was expressed at low levels in different tissues, probably due to the leakiness of the stop cassette. The level of spontaneous TagLuc expression, detected by bioluminescent imaging, varied between the different Tg lines, depended on the nature of the Tg expression cassette, and correlated with Tag-specific CTL tolerance. Following liver-specific Cre-loxP site-mediated excision of the stop cassette that separated the promoter from the TagLuc fusion gene, hepatocellular carcinoma development was visualized. The ubiquitous low level TagLuc expression caused the failure of transferred effector T cells to reject Tag-expressing tumors rather than causing graft-versus-host disease. This model may be useful to study different levels of tolerance, monitor tumor development at an early stage, and rapidly visualize the efficacy of therapeutic intervention versus potential side effects of low-level Ag expression in normal tissues.

Urokinase receptor (urokinase-type plasminogen activator receptor [uPAR], CD87), a GPI-anchored protein, is considered to play an important role in inflammation and fibrinolysis. The Gram-negative bacterium Burkholderia pseudomallei is able to survive and replicate within leukocytes and causes melioidosis, an important cause of pneumonia-derived community-acquired sepsis in Southeast Asia. In this study, we investigated the expression and function of uPAR both in patients with septic melioidosis and in a murine model of experimental melioidosis. uPAR mRNA and surface expression was increased in patients with septic melioidosis in/on both peripheral blood monocytes and granulocytes as well as in the pulmonary compartment during experimental pneumonia-derived melioidosis in mice. uPAR-deficient mice intranasally infected with B. pseudomallei showed an enhanced growth and dissemination of B. pseudomallei when compared with wild-type mice, corresponding with increased pulmonary and hepatic inflammation. uPAR knockout mice demonstrated significantly reduced neutrophil migration toward the pulmonary compartment after inoculation with B. pseudomallei. Further in vitro experiments showed that uPAR-deficient macrophages and granulocytes display a markedly impaired phagocytosis of B. pseudomallei. Additional studies showed that uPAR deficiency did not influence hemostatic and fibrinolytic responses during severe melioidosis. These data suggest that uPAR is crucially involved in the host defense against sepsis caused by B. pseudomallei by facilitating the migration of neutrophils toward the primary site of infection and subsequently facilitating the phagocytosis of B. pseudomallei.

IgA is a specific isotype required for mucosal immunity and is the most abundant Ab produced in vivo. Recently, several inductive signals for IgA class switch recombination have been identified; however, the molecular details of the action of these signals and the specific factors acting in B cells remain elusive. In this study, we show that combination of retinoic acid (RA) and TGF-β1 with other factors induced a much higher frequency of IgA-switched cells than reported previously. In addition, IgA production is severely impaired in Runx2-Runx3 double-deficient mice. In Runx2-Runx3–deficient B cells, both RA- and TGF-β1–dependent inductions of α germline transcription are completely blocked. These data suggest that Runx proteins play an essential role in IgA class switching acting downstream of RA and TGF-β1 signaling.
Mechanism of T Cell Tolerance Induced by Myeloid-Derived Suppressor Cells

Ag-specific T cell tolerance plays a critical role in tumor escape. Recent studies implicated myeloid-derived suppressor cells (MDSCs) in the induction of CD8+ T cell tolerance in tumor-bearing hosts. However, the mechanism of this phenomenon remained unclear. We have found that incubation of Ag-specific CD8+ T cells, with peptide-loaded MDSCs, did not induce signaling downstream of TCR. However, it prevented subsequent signaling from peptide-loaded dendritic cells. Using double TCR transgenic CD8+ T cells, we have demonstrated that MDSC induced tolerance to only the peptide, which was presented by MDSCs. T cell response to the peptide specific to the other TCR was not affected. Incubation of MDSCs with Ag-specific CD8+ T cells caused nitration of the molecules on the surface of CD8+ T cells, localized to the site of physical interaction between MDSC and T cells, which involves preferentially only TCR specific for the peptide presented by MDSCs. Postincubation with MDSCs, only nitrotyrosine-positive CD8+ T cells demonstrated profound nonresponsiveness to the specific peptide, whereas nitrotyrosine-negative CD8+ T cells responded normally to that stimulation. MDSCs caused dissociation between TCR and CD3ζ molecules, disrupting TCR complexes on T cells. Thus, these data describe a novel mechanism of Ag-specific CD8+ T cell tolerance in cancer.
c-Myb Promotes the Survival of CD4+CD8+ Double-Positive Thymocytes through Upregulation of Bcl-xL
Authors: Yuan Joan , Crittenden Rowena B. , Bender Timothy P.
Published: February 2010

Mechanisms that regulate the lifespan of CD4+CD8+ double-positive (DP) thymocytes help shape the peripheral T cell repertoire. However, the molecular mechanisms controlling DP thymocyte survival remain poorly understood. The Myb proto-oncogene encodes a transcription factor required during multiple stages of T cell development. We demonstrate that Myb mRNA expression is upregulated as thymocytes differentiate from the double-negative into the metabolically quiescent, small, preselection DP stage during T cell development. Using a conditional deletion mouse model, we demonstrate that Myb-deficient DP thymocytes undergo premature apoptosis, resulting in a limited Tcrα repertoire biased toward 5′ Jα segment usage. Premature apoptosis occurs specifically in the small preselection DP compartment in an αβTCR-independent manner and is a consequence of decreased Bcl-xL expression. Forced Bcl-xL expression is able to rescue survival, and reintroduction of c-Myb restores both Bcl-xL expression and the small preselection DP compartment. We further demonstrate that c-Myb promotes transcription at the Bcl2l1 locus via a genetic pathway that is independent of the expression of T cell-specific factor-1 or RORγt, two transcription factors that induce Bcl-xL expression in T cell development. Thus, Bcl-xL is a novel mediator of c-Myb activity during normal T cell development.

Periprosthetic Joint Infection in Patients With Arthroplasty Undergoing Perioperative Colonoscopy
Authors: Anderson Ashley B. , Slaven Sean E. , Watson Nora L. , Cody John P. , McGill Robert J. , Potter Benjamin K. , Nealeigh Matthew D.
Published: May 2024

Importance

Periprosthetic joint infection (PJI) is a rare but devastating complication. Most patients undergoing total joint arthroplasty (TJA) also need routine screening colonoscopy, in which transient bacteremia may be a potential source for hematogenous PJI. Patients and surgeons must decide on an optimal time span or sequence for these 2 generally elective procedures, but no such guidelines currently exist.

Objective

To evaluate associations of colonoscopy with the risk of post-TJA PJI for the development of clinical practice recommendations for colonoscopy screening in patients undergoing TJA.

Design, Setting, and Participants

This retrospective cohort study of Military Health System (MHS) beneficiaries older than 45 years who underwent TJA from January 1, 2010, to December 31, 2016, used propensity score matching and logistic regression to evaluate associations of colonoscopy with PJI risk. Statistical analyses were conducted between January and October 2023.

Exposure

Colonoscopy status was defined by Current Procedural Terminology code for diagnostic colonoscopy within 6 months before or 6 months after TJA.

Main Outcomes and Measures

Periprosthetic joint infection status was defined by a PJI International Classification of Diseases code within 1 year after TJA and within 1 year from the post-TJA index colonoscopy date.

Results

Analyses included 243 671 patients (mean [SD] age, 70.4 [10.0] years; 144 083 [59.1%] female) who underwent TJA in the MHS from 2010 to 2016. In the preoperative colonoscopy cohort, 325 patients (2.8%) had PJI within 1 year postoperatively. In the postoperative colonoscopy cohort, 138 patients (1.8%) had PJI within 1 year from the index colonoscopy date. In separate analyses of colonoscopy status within 6 months before and 6 months after TJA, younger age, male sex, and several chronic health conditions (diabetes, kidney disease, and pulmonary disease) were each associated with higher PJI risk. However, no association was found with PJI risk for perioperative colonoscopy preoperatively (adjusted odds ratio, 1.10; 95% CI, 0.98-1.23) or postoperatively (adjusted odds ratio, 0.90; 95% CI, 0.74-1.08).

Conclusions and Relevance

In this large retrospective cohort of patients undergoing TJA, perioperative screening colonoscopy was not associated with PJI and should not be delayed for periprocedural risk. However, health conditions were independently associated with PJI and should be medically optimized.
