This species is generally smaller than preceding, violet or blackish 
blue, beneath almost black, and the elytra are wider than thorax. ‘The 
antennee are quite stout, tapering toward tip and are serrate. Length .40 
to .52 inch, = 10—13 mm. _ Hab. Texas. 
C. cicatricosum, Mann. Bull. Mosc. 1853, III, p. 246. 
The thorax is marked by three longitudinal raised lines and is 
densely pubescent; the elytra are thickly coated with conspicuous hair, 
except where the surface is interrupted by raised glabrous lines which 
cross each other and present the appearance of net work. Length .50 
inch, =12.5mm. Hab. Colorado.

This species varies considerably in size and but little in other re—

This genus presents another remarkable form. The antenne are 
very stout, quite hairy, the thorax very convex and rounded at the sides, 
the elytra constricted behind the base and strongly rounded at tip and 
the entire surface deeply punctured and pubescent. Two species have 
been distinguished; 
More slender, elytral punctures before middle gross, somewhat confluent, surface 
shining; behind middle finer, surface opaque .... ...... ....... Agassizil. 
More robust, surface all shining, punctures large, foveate, irregular, more or less con-

The hair behind the middle of elytra is more dense, and 3d and 4th 
joints of antennze about equal. Length .45 inch, =12mm. Habitat, 
California.
