subgenerically. The species, with synonymy, will stand as 
follows — 
Neopalla hydropica (Muls.) 
Neopalla lebasi (Muls.) 
Syn. Neda murilloi Chpn. 
Dargo new name 
Oeneis Mulsant, 1850, loc. cit., p. 497, 500; not Oeneis 
Hiibner, 1819, Verz. bekannt. Schmett., (4), p. 58. 
Type of genus — Oeneis nigrans Muls. 
Mulsant proposed the genus Oeneis for two Brazilian 
species, Oeneis obscura n. sp. and 0. nigrans n. sp. Crotch, 
in his Revision of Coccinellidae, 1874, p. 206, selected O. 
nigrans Muls. as genotype and at the same time suppressed 
the genus as a synonym of Cryptognatha Muls. This may 
have been an unfortunate selection, for a study of the 
types of the two species may very well show that the two 
species are not congeneric and that O. nigrans Muls. be- 
longs in what is now known as Delphastus Casey. If my 
supposition is correct, Dargo will fall as a synonym of 
Delphastus and a new genus will have to be defined for 
O. obscura Muls. and its allies. — Edward A. Chapin,
