 (Chri/somela) (1758) - Coccinclla surinamensis, Linn. 

 Cent. Ins., p. 10 (1763) - Acgithus surinamcnsis, Lac. 

 Mon. Erot., p. 285 (1842). 



Specimens in my Collection are from Costa Rica, Colum- 

 bia, Ecuador, Amazons, Brazil. 



Distinct by its smooth elytra, which together with the 

 abdomen are testaceous. Linn?eus's davicornis was des- 

 cribed from Rolander's specimens, which were again 

 described by De Geer, so that the identity of the two is 

 certain. 



Intermediate coxal line distinct. 



BRACHYSPHCENUS, Lac. Mon. Erot., p. 296 (1842). 



(Type-?) 



This genus is still a magazine of different forms, but I 

 have not found any good characters whereby to separate 

 them. Sphenoxus and Tgpocephalus appear to me good 

 genera. B. irroratus and £. multinotattis are Priotcli, and 

 others are mixed up in the several sections. 



19. Brachysphcenus zonula, sp. nov. 



B. circulo proximus, sed humeris late nigris, annulo flavo 

 antice posticeque denticulato distinctis. L. c. 3 lin. 



Ecuador (Buckley). 



I cannot separate the single specimen from Chontales 

 now before me from the species characterized above taken 

 in Ecuador by Mr. Buckley. It differs only in that the 

 yeUow margin extends up to the shoulder, instead of 

 obliquely across as in Mr. Buckley's specimens.

 (1842). 



Occurs likewise in Venezuela. Coll. Chevrolat.
