428 Coleopterological Notices, VII. 



fectly simple first segment, broadly obtuse abdominal process and 

 subequal four basal joints of the tarsi, characterizing the greater 

 number of species, the male has the terminal tibial spur, which is^ 

 so essentially characteristic a feature in the capillosulum group, 

 and, except in these three species, unknown elsewhere in the 

 genus. 



The description above given is taken from a Louisiana female^ 

 and the series from Austin, Texas, before me, agrees fairly well; 

 in this series the male differs from the female in being slightly 

 stouter. The spur of the hind tibiae in the male is slender and 

 not quite half as long as the tarsus. As in many other species- 

 the abdomen is dusky, becoming paler. toward tip. 



38. C veatricosum n. sp. — Eather stout and conspicuously ventricose, 

 polished, impunctate, pale rufo-testaceous throughout the body, legs and an- 

 tennae; pubescence moderate in abundance, coarse, suberect, pale, rather re- 

 curved and mingled with longer and more erect sparse setae on the elytra. 

 Head orbicular, nearly as long as wide, subcircular behind, the eyes quite 

 small and only slightly convex; front not appreciably concave; clypeus short, 

 asperulate, with the apical margin perfectly simple and rectilinear. Antennse 

 slender, with a narrow and rather gradually formed club, distinctly longer 

 than the head and prothorax; second joint large though slightly shorter and 

 thinner than the first, feebly obconic, % longer than wide, rather longer than- 

 the next two and much thicker ; three to six equal in width ; third distinctly 

 shorter than wide; sixth quadrate; fourth slightly, and fifth distinctly, longer 

 than wide ; seventh about % wider and longer than the sixth, svyollen at apex, 

 as long as wide; eighth scarcely % wider, fully as long as wide; ninth and 

 tenth almost exactly equal, nearly }4, wider than the preceding and about as 

 long as wide; eleventh stouter, very obliquely pointed, not quite as long as 

 the two preceding. Prothorax rather small, feebly conic, the sides distinctly 

 arcuate, not quite as long as wide ; apex fully ^ as wide as the base, which is 

 not more than }ii wider than the head; surface perfectly even and convex. 

 Elytra inflated, }^ longer than wide, a little more than tvrice as long as the 

 prothorax and very nearly twice as wide, widest only slightly before the mid- 

 dle; sides arcuate ; humeral plica small but distinct, the adjacent impression 

 rather small but very evident; fovese distinct; subsutural impressions subobso- 

 lete, the suture completely unmodified at any part. Abdomen dusky, pale at 

 apex, the first segment perfectly normal. Legs well developed ; femora rather 

 strongly clavate, particularly the anterior pair; hind tarsi long and slender, 

 with the joints decreasing very slowly in length to the fourth. Length 1.25 

 mm. ; vddth 0.5 mm.

The male, which serves for the above description, has a slender, 

 simple and straight spur projecting obliquely from the apex of
