sparse whorl of long, slender, curved setae, the loops of the basal 
circumfilum scarcely extending to the middle of this enlargement, 
those of the distal hardly beyond its apex; terminal segment (fig. 20b) 
with the basal enlargement subglobular, separated from the pro- 
longed distal swelling by a short, slender stem, the latter with the 
basal two-thirds cylindric, slightly constricted at the distal third, 
the terminal portion slender, subconical. Palpi (fig. 20c); the first 
segment broadly and irregularly oval, the second a little longer, 
stouter, the third a little longer and more slender than the second, 
and the fourth a little longer than the third; face yellowish brown, 
eyes large, black. Mesonotum a variable reddish brown, lighter 
posteriorly, submedian lines yellowish. Scutellum yellowish, post- 
scutellum and abdomen pale yellowish brown. Wings hyaline, 
costa light brown, the third vein joins the margin well beyond the 
apex; halteres yellowish transparent basally, fuscous apically. Legs 
pale brown, tarsi slightly darker; claws slender, very strongly bent, 
almost forming a right angle, simple. Genitalia; basal clasp seg- 
ment stout, slightly produced at the internal basal third, excavated 
at the distal third; terminal clasp segment stout, tapering, a heavy 
apical spur; dorsal plate broad, deeply and roundly emarginate, the 
lobes with a greatly prolonged latero-posterior process, curving 
therefrom to a minor submedian process, the angles with long, stout 
setae; ventral plate slender, deeply and roundly emarginate, the 
lobes slender. Harpes long, slender, apparently consisting of two 
slender, chitinous processes extending along the slender lobes of the 
ventral plate. Type Cecid. 132. 
Hyperdiplosis coffeae Felt 
1911 Felt, E. P. Ent. News, 22:305 
The midge was reared February 3, 1911 by W. H. Patterson, St 
Vincent, W. I., from the fruits of the Liberian coffee tree, Coffea 
liberica. It is tentatively referred to this genus, although the 
claws are less strongly bent, and the circumfila are more produced 
than in other species placed in this group. 
Hyperdiplosis fungicola Felt 
1911 Felt, E. P. Econ. Ent. Jour., 4:552-53 
This delicate, yellowish species was reared in August 1897 from 
larvae on the outside of a nearly rotten, fungus affected nectarine 
received at the bureau of entomology from Mrs R. B. Tenney, 
Washington, D. C. It is closely allied to H. lobata Felt 
from which it is most easily separated by colorational characters. 
Larva. Length 1.5 mm, moderately stout, tapering anteriorly, 
pale yellowish. Head moderate, tapering, broadly rounded distally. 
Antennae stout, with a length three times the diameter; breastbone 
wanting. Skin coarsely shagreened, each segment laterally with a 
stout seta near the middle; posterior extremity subtruncate, with
