A very abundant Tropical-American species, ranging from Northern Mexico to Brazil. 
With long series of specimens from the same localities, the colour of the underside 
proves (as in C. bifossulata) to be of no value as a specific character. In typical 
C. trisignata, of which we have received many specimens from Yucatan, the underside 
is entirely testaceous; in C. bis-tripunctata it is in great part black; in C. bi-impressa 
(described as having the underside flavescent) it is also in great part black in the 
majority of the large number of examples before me, both forms having occurred 
together at Jalapa and elsewhere. The three elytral spots, when present, are larger 
and more distinct than in C. difossulata or C. bicolor ; but they are sometimes obsolete 
or small, or the posterior one only (C. bi-impressa) may be obliterated. C. trisignata 
also varies greatly in size, the males, as usual, being shorter and more rotundate than 
the females. C. bis-tripunctata, Herbst, from Maryland, is doubtfully quoted as a 
synonym by Boheman; it is perhaps a variety of C. bicolor, Fabr. The Mexican 
specimens in the British Museum which were referred by Boheman to C. limpida * 
(a Brazilian insect) probably belong here; they appear to be small pallid males 
of the var. bi-impressa. The Brazilian C. sexpunctata, Fabr., is a very close ally of 
_C. trisignata.
