 Ischyrus anriculatus.

 anterior angles frilvoiis.

Ischyrus distinguendus, Lac. Erot. 111. 

 Mexico. 



Ischyrus collatinus, sp. n. 



Fulvus, oblongus, subtus niger, prosterni latei'ibus rufis ; ca])ite 

 rufo vertice nigro, thorace ci'ebrius punctatis, subtransverso, late- 

 ribus rotundatis, antice angustlore, linea transversali discoidali 

 nigra (utrinque abbreviata) basique nigro margiuato in medio; 

 scutello nigro ; elytris subltevibus punctato-striatis, singiilo maculis

 versus, 1 transversa paulo, aute medium, 1 minima mai'ginem 

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

N. Granada. 



The colouring is unique in this gentis. 



Epytus. 



I)ej. Cat. 452 {f>/p. violaceiis, Sturm). 



[Ooet/anus, Hope, 1841, Lac. Erot. 194.] 



This genus differs fr'om Ischyrus by the almost equal dilata- 

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

 granulated, though Lacordaire gives them as being finely so. 

 The species are 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. 



Ischyrus 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- 

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