EROTYLUS.— CYPHEKOTYLTJS. 103 



black apex. The piliferous spot in the male is a small patch clothed with blackish- 

 brown hair. 



Twelve specimens, seven of which are males. 



CYPHEROTYLUS. 



Cypherotylus, Crotch, Cist. Ent. i. p. 148 (1873), & p. 537 (1876). 



Under this name Crotch included all those species of Lacordaire's genus Erotylus 

 which have the front of the head coarctate, the elytra with black impressed punctures, 

 and the thorax margined at the base. Many of the species are remarkable for the 

 way in which their elytra are elevated. This genus attains a higher degree of latitude 

 than the true Erotyli, several species being found in Mexico, and one or two passing 

 the Rio Grande, while comparatively few are known as existing south of the Amazons. 



Section I. Elytra strongly gibbose, the middle of the suture acuminate. 



1. Cypherotylus debauvei. (Tab. VI. figg. 2, 2 a, <$ .)

Hab. Panama, Volcan de Chiriqui 2500 feet {Champion). — Colombia 23 ; Guiana 12 , 

 Cayenne 23 ; Bolivia 2 ; Beazil 3 . 



Two specimens, a male and a female, of this species are all I have seen from Central 

 America. It is easily recognized among other species of the same section by the two 

 posterior pairs of legs having the femora coral-red in the middle. 



2. Cypherotylus dromedarius.

Section II. Elytra gibbose, the suture forming an even keel.
