Dipsomyia, Bezzi, Nova Acta Akad. Naturf. Halle, Vol. 91, p. 389 (1909). 
Characters. — Head rounded, ocellar prominence with long, well-separated bristles; face bare, 
cheeks narrow; antennz short, the third joint very short, bearing a thick arista which is twice as long as 
the antennze; proboscis thick, blunt, vertical or slightly inclined, the palpi large, exserted perpendicul-- 
arly, black. Thorax but little convex, opaque cinereous; dorsocentral bristles strong, extending to the 
front margin, alternating large and small bristles, acrostichals distinct, biseriate, scutellum with marginal 
hairs in addition to the two bristles; metapleurz bare. Legs black, front coxz one-fourth as long as 
their femora, with projecting sete in front, front femora incrassate, spinose at their base, front tibiae 
pectinate within with short bristles, pulvilli-distinct but small. Wings elongate, narrow, rather pointed, 
the axillary angle very obtuse, no stigma, costa extending around the hind margin, humeral crossvein 
present, auxiliary vein evanescent apically, first vein ending beyond the middle of the wing, third vein 
furcate, its pedicel arising near the middle of the second basal cell, fourth vein arising at the base of the 
anal cell, discal cell rather large, complete, emitting three posterior veins, the second posterior cell 
sessile, anal cell shorter than the second basal, the crossvein rounded and distinct from the anal fold. 
Type species : D. spinifera, Bezzi, from South America. the only known species. Bezzi states 
that this genus seems intermediate between PAilotutra and Hilarempis, resembling the former in its general — 
venation, shortened antennz and lengthened bristles, but differing in its lengthened proboscis, thickened 
front femora and long second basal cell.

8. GENUs PROCLINOPYGA, NOV. GEN. 
Characters. — Slender olivaceous species with black legs. Head globular, eyes of both sexes 
widely separated, facets uniform, bare, front wide the sides converging toward the antennze, ocelli large, 
not elevated, a pair of strong diverging distant ocellar bristles behind which on the level of the posterior 
ocelli is a pair of smaller diverging approximated lesser ocellars; sides of the face parallel, the face of 
the female broader than in the male; cheeks small and narcow but separated from the face; antennze 
located above the middle of the head, plainly three-jointed, the basal joints subequal, the third joint 
conical but with concave sides, arista terminal, as long as the third joint, thickened, geniculate at its 
attachment, three-jointed, the basal segment minute and quadrate, the apical part consisting of a 
microscopic hair; proboscis very short, thick, fleshy, and blunt, palpi short, horizontal, rather clavate 
and hairy ; occipital hairs biseriate, the uppermost bristle-like. Thorax broader than the head, entirely 
pollinose, no pubescence, bristles prominent, metathorax longer than the scutellum and not declivous, 
one humeral, one posthumeral, an oblique row of three notopleurals, several supra-alars, one postalar,
