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

 (Type Gocc. gujantca, Linn.) 



This 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, maculis nigris tes- 

 sellatis, margine epipleurisque rufis. L. c. 71 lin. 



The geminate striic are very closely approximate, and 

 separate the black spots from each otlier by yellow lines. 



CYPHEEOTYLUS, gen. nov. 

 (Type Chrysom gihhosa, Linn.) 



The genus appears to me more defined than any of those 

 with a narrower rostrum, except perhaps Homceotdns. 

 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 condjine to separate it at once. 



The acute gibbosity of C. sphacclatus fades gradually 

 into the convex form of C. Goryi. 



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



(Erotylus) (1842). 



This does not differ sufficiently to entitle it to specific 

 distinction ; the elytra! punctures arc rather finer, and the 

 median black spot is larger. 



23. Cypherotylus imiircssopiinctaiiis, sp. nov. 



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

 bosus) ; thorace lateribus rectis, antice angustato, basi
