[March, 'zoPhyllopecta, a nomen nudum of Riley's, is made t:y Zacher
to replace Trioza tripunctata Fitch. This name can be givenno consideration because the species is clearly a member ofTrioza.
Psyllopa Crawford has been merged by its author with
Aryta'inia.E Several species were described in Psyttopa but
all are now referred to the European genus, Arytaina.
Zacher has tangled himself in the translation of the English
language when he catalogs Trioza tr,ipunctata Low as a synonym of Psyl,la Kuwayamai Crawford. The synonymy ofthree specific names is correctly as follows:6
Psylln tripunctata Fitch (r851)-referred to Trioza tripunctata (Fitch) by Riley in 1893. This is a valid species.
Tri.oza lripunctata Low (t877), preoccupied. Sulc has
declared this speciesto be identical with Trioza trisignataL6w.
Hence T. tripunctata Low (nec Fitch) is a synonym of I.
trisi,gnata Low.
Psylla tripunctala Kuwayama (r9o8), preoccupied by
Fitch's old name for the American species now known as
Trioza tripunclata.
Hence, the Psylla species name has beenchanged to Ps. kutuayamai Crawford. This is Nor a synonymof. Trioza tripunctata, as Zacher states.
Trioza sonchi is one of Riley's nomina nudabut resurrectedby Zacher. The same insect (probably) was described in r9r4
as Hemitrioza sonchi Crawford.

Psaronius brevitibia sp. n.
General coloration light brown; head and mesonotal praescutum unmarked with darker; metatarsi whitish; tibiae short; wings pale yellow,sparselymarked with darker; vein Rz entirely atrophied.
9.-Length 24 mrn.; wing r4.4 mm.; abdomen alone r9.5 mm. Rostrum and palpi dark brown. Antennae with the scapal segmentslightbrownish yellow; flagellumbroken. Head rufous brown, narrowly silvery
adjoining the eyes; occiput and adjoining parts of the vertex dull brown.
Mesonotal praescutum light brown without distinct stripes; scutumand postnotum with a very indistinct median line. pleura pale rvithout
distinct markings.
Legs with the femora and tibiae light brown, the tips of the latter narrowly dark brownish black; metatarsi whitish, the baseand apex narrowly
darkened; remainder of the tarsi dark brown; tibiae comparatively short(hind tibiae r r.S mm. ; in P. pygmaeztsr4.z mm.).
Wings pale yellow, the costal and subcostalcells deeperyellow; small
dark brown seamsat the origin and fork of -R.s,and as very narrow seams
along the cord and outer end of cell rsl Mz; wing-apexin cells -Rz,Rs, R;
and Mt faintly darkened; veins dark brown, C, Sc,R, Rs and Rr yellow.
Venation: vein Rz entirely atrophied, quite as in P, abnormisAlexander;
cell Mr about equal to or a little shorter than its petiole.
Abdominal tergites brown, the sternitesmore yellowish.

Hololype: 9, Obidos, August 28, rgrg (H. S. Parish).
By means of the author's key to Psaronius, cited under thepreceding species, P. breviti,biawould run to P. abnorrnis, ofParaguay, a greyish fly with the costal margin of the wings
conspicuously infuscated. It much more resembles P. pyglnaeus Alexander (Guiana-Brazil) which has vein R, imperfectly preserved, being represented by a short spur that isfused with Rr at the tip; this species has the tibiae considerably longer as given above, and the details of venation andcoloration are slightly different.

Halteres dark brown, the extreme base of the stem pale. Legs with thecoxae testaceous; trochanters paie brown; remainder of the legs palebrow n; no ti bi al spurs.
Wings with a strong grey suffusion; veins brown. Venation; almost
as in P. conjuncto but ftzar a little longer; Rs before r a iittle longer; basal
deflection of Czrr some distance beyond the fork ol M and cell Ms much
deeper, vein Mr alone being longer than the fused portion of. Mt and Ca.
Abdomen dark brown, the sternites a little paler. Ovipositor with thevalves horn-colored, long, straight, the tips acute.

Hol,otype: Q . Itacontiara, October r6, 19r9 (H. S. Parish)The lack, or apparent lack, of tibial spurs would refer thisfly to the genus Eril/tera rather than Polymera, yet the appearance of the insect is so very similar to speciesof this lattergenus that it is referred here, at least provisionally. Whether
the tibial spurs are similarly lacking in P. conjunclo Alexandercannot be determined at this time as no specimensare at hand.
Brachypremnauniformis sp. n..
Close to B. d,ispell,ens;femora and tibiae uniformly dark brown, thetarsi fadrng into cream-color.
g.-Length
r5 mm.; wing r4.z mm.
Generally similar to B. d,ispeltrens(Walker), differing as follows: Palpi with the first segment dark brown.
the apex narrowly pale; segment two entirely pale yellow; segment threeblack basally, about the outer third obscure yellow; last segment blackwith the extreme tip conspicuous yellow.
Mesonotal praescutum with theintermediate pair of brown stripes broader. I-egs with the femora andtibiae of all the legs uniform brown; tarsi pale brown, the distal segments
passing into cream color. Abdominal sternites one to eight with an elongate-oval black dash near the center of each segment.

Holotype: 9, Parintins, October 8, r9r9 (H. S. Parish).
Brachypremna uniJormis differs conspicuously from all theknown species of the genus with the exception of B. unicolor
Osten Sacken (Antilles) in the uniformly dark femora andtibiae. By means of the author's key to the speciesof thisgenus (Journ. N. Y. Ent. Soc., vol. zo, p.228; rgr2), B. uni.
formis would not run past the initial couplet because of thecombination of venation and leg-coloration. The venationis quite as in B. d,ispellensand related species but the entireabsence of white on the femora and tibiae precludes its reference to any of these species. B. unicolor differs from allother speciesof the genus as known, including this new form,.
in the very curious wing-venation.
