148 Mr. Crotch's Descriptions of 



EROTYLUS, Fab. Syst. Ent., p. 123 (1775). 

 (Type Cocc. gigantca, Linn.) 



Tliis genus seems to me somewhat difficult to charac- 

 terize, as Lacordaire has comprised species with the rostrum 

 parallel and coarctate in it. 



All are of tolerably large size, and more or less visibly 

 gemellate-punctate. 



21. Erotylus Nicaragua, sp. nov. 



Ovatus, niger, nitidus, thorace punctato, elytris laete 

 flavis, sat regulariter gemellato-striatis, raaculis nigris tes- 

 sellatis, margine epipleurisque nifis. L. c. 7i lin. 



The geminate strite are very closely approximate, and 

 separate the black spots from each other by yellow lines. 



CYPHEROTYLUS, gen. nov. 

 (Type Chrysom gibhosa, Linn.) 



The genus appears to me more defined than any of those 

 with a narrower rostrum, except perhaps Homceotclus. 

 The uniform coloration (black, elytra pale whitish, with 

 impressed irregular black dots), the thorax margined at the 

 base, the interstitial punctuation hardly apparent, the sexual 

 differences, all combine to separate it at once. 



The acute gil)l)osity of C. sphacelatus fades gradually 

 into the convex form of C. Goryi. 



22. Cypherotylus dromcdarius, Lac. Mon. Erot., p. 455 

 {Erotylus) (1842). 



This does not differ sufficiently to entitle it to specific 

 distinction ; the elytral punctures are rather finer, and the 

 median black spot is larger. 



23. Cypher otylus impressopunctatus, sp. nov. 



Niger, paulo abovatus, acute convexus (sed hand gib- 

 bosus) ; thorace lateribus rectis, antice angustato, basi
