Widely dispersed and often abundant ; Mr. Champion met with it in numbers at 

 El Eeposo. 



C. dentatus has some claims to generic distinction, it being not only natter than 

 the other species of the genus, but the males have the first abdominal segment with a 

 distinct carina. 



The form which has the elytra with seven distinct spots is much commoner than that 

 described by Gerstacker as the type, of which indeed no example is contained in the 

 large number of specimens now before me. Of the variety (fig. 6), which has the 

 thoracic spots united, and the elytra black, with the margins, a single interrupted 

 fascia, and the suture in the middle red, we have received three examples from 

 El Eeposo. 



Fig. 5 is taken from a specimen from Belize. 



ACINACES. 



Acinaces, Gerstacker, Monogr. Endom. p. 178 (1858). 



Four species of this genus have been described by Gerstacker, and no additional 

 representative has been added since the publication of the Monograph ; nor has any 

 species hitherto been recorded from the northern continent, but one is found as far 

 south as La Plata.

From the State of Panama we have received a single specimen of this species, which 

 we figure. Gerstacker only figures the prosternum and mesosternum diagrammatically.
