the Coleopterous Family Erotylidce. (57) 433 

 Ischyrus auriculatus. 



Ischyrus auriculatus, Lac. Erot. 123. 

 Cayenne, Bahia. 



Distinct from all others by the thoi'ax being black with the 

 anterior angles fulvous. 



Ischyrus distinguendus. 



Ischyrus distinyuendus, Lac. Erot. 111. 

 Mexico. 



Ischyrus collatinus, sp. n. 



Fulvus, oblongus, subtus niger, prosterni lateribus rufis ; capite 

 rufo vertice nigro, thorace crebrius punctatis, subtransverso, late- 

 ribus rotundatis, antice angustiore, linea transversali discoidali 

 nigra (utrinque abbreviata) basique nigro marginato in medio; 

 scutello nigro; elytris sublsevibus punctato-striatis, singulo maculis 

 nigris 7; 1 transversa paulo infra scutellum, 1 minima marginem 

 versus, 1 transversa paulo ante medium, 1 minima marginem 

 versus, 1 obliqua in tertia apicali, 1 subapicali, ad suturam con- 

 juncta. L. 3 lin. 



N. Granada. 



The colouring is uniqu.e in this genus. 



Epytus. 



Bej. Cat. 452 (typ. violaceus, Sturm). 



[Oocyanus, Hope, 1841, Lac. Erot. 194.] 



This genus differs from Ischyrus by the almost equal dilata- 

 tion of the labial and maxillary palpi. The eyes are coarsely 

 granulated, though Lacordaiie gives them as being finely so. 

 The species ai"e apparently confined to the West Indies. 



Epytus violaceus. 



Erotylus violaceus, Sturm, Cat. 82, T. iv. f. 38 (1826). 



Oocyanus , Lac. Erot. 196. 



Cuba. 



Epytus tarsatus. 



Oocyanus tarsatus, Lac^ Erot. 196. 



Iscliyrus tarsalis, Lac. Erot. 106. 



Cuba, Columbia (Reiche). 



I cannot doubt from the descriptions that Lacordaire has de* 

 scribed this species twice over, the only discrepancy being size. 



The locality "Columbia" assigned to Reiche's specimen is pro- 

 baVjly erroneous, as I have seen numerous examples from Cuba.
