lent me by M. René Oberthiir) to C. semilobata. The latter differs from the present 
insect in the relatively broader elytra and more prominent humeri, and in having the 
black dorsal patch more broadly and more deeply emarginate at the sides; the discoidal 
patch on the prothorax, too, being parallel at the sides and acutely produced in front 
(instead of triangular as in C. stali). Boheman’s var. a of C. punicea®, of which there 
is a specimen in the Sallé collection with his ticket attached, is evidently a pallid 
example of C. stali. We figure a well-marked male example from Teapa.

Of this insect I have seen three specimens of the typical form, including the type; 
one of these has the scutellum yellow and the elytral punctuation finer. C. salebrata 
is based upon a pallid example of the same species; and the var. B, of which four 
specimens have been obtained, is probably a small smooth form of it. C. infantula 
closely resembles C. lugubris, but may be known from it by the single (post-median) 
transverse black fascia on the elytral margins. We figure Boheman’s types, both 
‘of which are contained in the Baly collection.

C. bilobata only differs from C. palmata in having the scutellum and the eighth and 
ninth joints of the antenne black, and it cannot be maintained as distinct, these 
characters being variable; the single specimen from Oaxaca is intermediate between 
the two forms. The species is apparently scarce, one or two specimens only having 
been received from each of the localities mentioned. C. palmata is closely allied to
