 which are very conspicuous in JEgithus, are here absent or almost obsolete.

The older authors considered this insect to be a mere variety of C. unicolor, a species 

 which occurs further south; but it is probable that they confounded with it others of 

 similar appearance. The references to Latreille and to Duponchel are given, as those 

 authors probably refer to this species in the text, though their figures do not apply to 

 it — that in Humboldt's work probably represents a Coccimorphus, but one more like 

 C. emys, and the Mexican locality, " Nouvelle Espagne, Jorullo " 2 , pointing also probably 

 to that species. Crotch gives " Guatemala ;" there is, however, no specimen from that 

 country in his collection.
