ment 1 robust, slightly expanded toward apex, three-fourths as long 
as third; segments 2 to 5 slender, cylindrical, the third twice as long 
as fourth; segments 6 to 11 slightly serrate, diminishing in length to 
the eleventh, which is acute at apex. 
Pronotum cylindrical, distinctly longer than wide, subequal in 
width at base and apex, widest just behind middle; sides arcuately 
rounded, more obliquely converging anteriorly; disk strongly convex 
and slightly uneven; surface coarsely, deeply, confluently ocellate- 
punctate, sparsely clothed with short, semierect, inconspicuous hairs. 
Scutellum densely clothed with short, recumbent, yellowish hairs. 
Elytra cuneiform, extending to middle of first abdominal sternite, 
at base subequal in width to pronotum behind middle, strongly de- 
hiscent along sutural margins at apical halves, the tips narrowly 
rounded; surface coarsely, rather densely, uniformly punctate, 
sparsely clothed with long, erect, yellowish hairs. 
Abdomen beneath indistinctly punctate, sparsely clothed with long 
and short, erect, inconspicuous hairs. Posterior legs long and slender ; 
femora abruptly clavate at apices and extending to tip of abdomen; 
tibia slender, cylindrical, not expanded toward apex, uniformly clothed 
with short, semierect, stiff hairs, but the hairs not forming tufts to-

Length 10 mm. width 1.75 mm. 
Type locality—Hamburg Farm, Costa Rica. 
Type.—U.S.N.M. No. 57680. 
Remarks.—Described from a single female collected at night on a 
freshly cut sapotaceous tree, January 3, 1937, by Ferdinand Nevermann. 
This species is allied to /schasia crassitarsis Gounelle, but it differs 
from the description given for that species in having the pronotum, 
elytra, and underside of the body brownish yellow, the dorsal surface 
of the pronotum slightly uneven, the elytra cuneiform and more 
strongly dehiscent posteriorly, and in not having the posterior tibiae 
expanded toward their apices. 
Genus EPIMELITTA Bates 
EPIMELITTA ACUTIPENNIS, new species 
Male—Short and rather robust, strongly flattened above. 
Head prolonged into a short snout, black, except clypeus, labrum, 
and mandibles, which are brownish yellow; surface densely, coarsely 
punctate on occiput, with a deep, longitudinal groove between the eyes, 
rather densely clothed with long, recumbent, pale yellow hairs; eyes 
large, deeply emarginate, separated from each other on the front by 
about the diameter of first antennal segment. Antenna short, slightly 
expanded toward apex, pale yellowish brown and strongly shining at 
base, becoming opaque and dark brown toward apex; segment 1 robust,
