534 (158) Mr. G. R Crotch's Revision of 



striatis, lateribus opacis, explanatis, vitta obliqua magna rufa ; 

 epipleuris macula media rufa, abdomine rufo, segmeutis medio 

 puuctoque laterali nigris. L. G^ — 8| lin. 



Amazons (Bates). 



Allied to B. gemmatus by its pp'amidal form, and very distinct 

 from all the other species. I can discover no sexual characters in 

 the series of examples which I have examined. The abdomen is 

 sometimes entirely black. The punctures on the elytra are black 

 on the red vitta. 



Erotylus geminatus, sp. n. 



Subovatus, niger, nitidus, elytris profunda punctatis dorso 

 gemellato-striatis, sti'iis valde approximatis, margine macidis vage 

 sparsis epipleimsque rubris. L. 6| lin. 



Amazons (Bates). 



Closely allied to U. pustulatus in appearance, but with a de- 

 cidedly pyramidal form, though less so than in E. gemmatus, from 

 which it differs by the regular dorsal striae. 



Erotylus helopioides. 



Erotylus Jielopioides, Dup. Erot. 2, T. i. f. 11. 



, Lac. Erot. 447. 



Lacordairei {Dej.), Lac. Erot. 446. 



Brazil. 



The impunctate elytra at once distinguish this species, I have 

 no doubt that E. helojnoides and E. Lacordairei are forms of one 

 and the same species. The former appears to be of very rare 

 occurrence ; I have seen but a single bad example of it.
