Flavo-testaccum : antennis apicem versus, elytris maculis sex

 quadricostatis, inters! itiis costulis transversis. Long. 4| lin.

The tborax is moderately narrowed in front, with a complete 

 well-defined mesial carina, the posterior angles acute. Elytra at 

 the base not wider than the thorax, gradually but not much wider 

 posteriorly, the three spots on each elytron are rather pale dusky. 



Since this species was originally described I have come to the 

 conclusion that it is only a variety of the American Calopteron tri- 

 color, Oliv. ; in which case the locality with which it is marked 

 must be an error. G. tricolor usually has the tibiic dusky, which is 

 not the case in the specimen described as notatum ; but the species is 

 very variable.
