Isolated from its congeners by the following characters in 
combination :—Femora of male unarmed, foliaceous margins of 
prothorax moderately wide (about the width of one-sixth of the 
disc), surface nitid, elytra strongly and evenly striated, hind 
angles of prothorax extremely prominent and acute, hind tibize of 
male strongly compressed and flexuous. It may be remarked that 
C. simulans, Haag-Rutenberg, is founded on a female; and the 
description, moreover, being a very bad one, omitting nearly all 
important characters, it is difficult to form a clear idea of what 
that insect is; but the expression “lang herzférmig” applied to 
its prothorax certainly does not fit the prothorax of this species, 
the width of which is just about once and two-thirds the length 
down the middle line. In Mr. Bates’ tabulation of Cardiothorac 
(E.M.M., 1879, pp. 32, &c.) the present insect would stand beside 
Castelnaudi and grandis, from both of which the even striation of 
its elytra distinguishes it. The greatest width of the prothorax 
is exactly equal to that of the elytra by measurement, but to a 
casual glance the prothorax appears slightly wider. <A strong 
character, if constant, is the oblique carina running across the 
foliaceous margins of the prothorax near the front, and cutting 
oft the front angles.

Distinguished at once from its previously-described congeners 
by the very much finer puncturation of its prothorax and the
