explanate, and without distinct prehumeral carinae; surface densely, 

 coarsely, very irregularly rugose, finely, sparsely punctate between 

 the rugae, and without distinct pubescence. Scutellum feebly, trans- 

 versely carinate, and the surface finely, densely reticulate. 



Elytra distinctly wider than pronotum at base, and about equal in 

 width at base and behind middle; sides feebly rounded for a short 

 distance behind the base, feebly, broadly constricted near middle, 

 broadly arcuately expanded behind middle, then obliquely narrowed 

 to the tips, which are separately, rather broadly rounded, and feebly 

 serrulate; sides of abdomen broadly exposed above; disk feebly de- 

 pressed, sutural margins slightly elevated posteriorly, and with 

 broad, shallow basal depressions ; surface densely, coarsely imbricate- 

 punctate, sparsely uniformly clothed with short, recumbent, white 

 hairs, and each elytron ornamented with more or less distinct pubes- 

 cent spots as follows : One in basal depression, one in front of middle, 

 and the other at apical third. 



Abdomen beneath rather densely, finely punctate, the punctures 

 connected transversely by fine, sinuate lines, which are coarser on 

 basal segment, and sparsely clothed with recumbent, whitish pubes- 

 cence, which is slightly longer at middle of basal segment ; first seg- 

 ment feebly convex at middle, last segment broadly rounded at apex ; 

 vertical portions of first segment rather densely pubescent ; pygidium 

 coarsely punctate, feebly, longitudinally carinate, but the carina not 

 projecting. Prosternum densely punctate, somewhat rugose, and 

 sparsely clothed with long, erect, inconspicuous hairs ; prosternal lobe 

 broad, strongly declivous, and broadly, rather deeply, arcuately 

 emarginate in front; prosternal process broad, the sides expanded 

 behind the coxal cavities, and truncate at apex (visible part). Tibiae 

 slender, anterior pair slightly arcuate, and the anterior and middle 

 pairs armed with a short tooth on inner margin at apex. Posterior 

 tarsi distinctly shorter than tibiae, and the first joint as long as the 

 following two joints united. Tarsal claws similar on all feet, cleft 

 near the middle, the inner tooth broad, shorter than outer one, and 

 not turned inward. 



Length, 6.75 mm. ; width, 1.75. 



Female. — Differs from the male in having the head more cupreous 

 in front; first two abdominal segments more finely punctured and 

 less pubescent; prosternum more sparsely punctured and the 

 pubescence at middle shorter, and the tibiae unarmed at apex. 



Redescribed from the male and female cotypes, Cat. No. 6608 in 

 the United States National Museum. 



Type locality. — Texas (definite locality unknown).
