During the past few years, numerous speciesof undescribed
Tipulidae from Eastern North America have come to hand andhave been diagnosed. In the present paper, the writer discusses
species of the genus Lintnophila pertaining to the subgenera
Ephelia Schiner and Phylidorea Bigot. The material upon which
this paper is based is iargely contained in material taken by thewriter; in extensive series of crane-flies taken by Professor J.
Speed Rogers in Michigan, Indiana, Tennesseeand Florida; andin collectionsfrom Ontario made by Mr. C. Howard Curran. A
ferv additional specimensconsidered at this time were included in
the U. S. National Museum and U. S. Biological Survey Collections and in an extensive series of Adirondack Tipulidae sent tome by IVIr. Howard Notman. I rn'ould express my sincere thanks
to all of the above mentioned entomologists for co-operation in
making knorvn the crane-fly fauna of the country.
Limnophila (Ephelia) solstitialis n. sp.
lVIale.-Lensth about 5 mm.; wing, 64z mm.
Female.-Length about 6.5 mm.; wing, 7-Z.S mm.
Generally similar to L. (E.) aprilina O. S., differing especiallyin the average smaller size, different lving-pattern and the structure of the male hypopygium.

having the two ends narrowlv conflueni; the short sublateral
stripes tending to fuse with the intermediatesat their anterior
encls. Wings with a more abundant pattern, the clorrds andseams along the cord, outer end of cell rs/ M, and at theends of the longitudinal veins more broken; two, or sometimes three, brown spots in the outer end of cell end A, there
being a small spot at the end of vein end A, with a larger,
more basal area lying near the outer enclsof cells tst A andzntl A, in transverse-alignment with the large costal blotch

The specimens of L. aprilina mentioned by Osten Sacken(Mon. Dipt. N. Amer., Part 4: zz4, t869; iast paragraph) probably refer to solstitialis. Likewise all records f.or apri,lina in my"Crane-flies of New York, Palt I: Bo9-8ro ; rgrg" pertain tosolstitialis with the exception of the Tompkins Co. records, whichrefer to aprilina. fn Johnson's "Diptera of New England," p. z9;
1925, all the records presumably refer to solstitialis with thesingle exception of the material taken at Whately Glen, Massachusetts,by the writer which again pertain to aprilina. It is probable that aprili,na flies much earlier than solstitiolis and mostrecords for June to August pertain to this latter species. The
records for aprilina and solstitiali,s are very confused. I am indebted to Dr. Nathan Banks of the Museum of Comparative Zoology for critical notes on the type-series of. aprilizo,' from thesenotes it is very apparent that Osten Sacken had two speciesconfused in his original series and that a third speciesfrom California was later added when the material from the "Western
Diptera" was incorporated in the coliection.
Limnophila (Ephelia) serotinella n. sp.
fuIale.-Length about 4.2-4.3 mm.; rving, 5-5.3 mm.
Female.-Length about 4.2 r;rm.; wing, 4.8 mm.

The size is smaller than all but the smallestindividuals of
solstitiaLis. The rn'ing-patternis somewhat heavier, there being in casesthree dark markings across the outer end of thelast anal cell. The rnale hypopl'gium has the outer dististylesmall, the basal half dilated, thence suddenlynarrowed to theacute simple apex ; the usual lateral spinous lobe is also
slenderbut blunt at the tip, placed far out at the apex of thestyle; the inner or cephalic margin of the style at its widest
point is produced into an obtuse lobe. Inner dististyle shortand broad.
Habitat: Tennessee.
