The larger size and widened elytral margins are the only characters whereby this 

 genus can at present be separated from Cycloneda ; as restricted by Crotch it includes 

 about eight American species. 



1. Neda ostrina. 



Coccinella ostrina, Erichs. Archiv fiirNaturg. xiii. i, p. 182 l . 



Neda ostrina, Muls. Monogr. Coccin. p. 199 2 ; Crotch, Rev. Coccin. p. 168 \ 



Neda orbignyi, Muls. Spec. Col. Trim, secur. p. 280 4 . 



Neda peruviana, Muls. loc. cit. p. 281 s ; Monogr. Coccin. p. 199 6 . 



Hob. Mexico 3 . — South Ameeica, Colombia 2 4 , Brazil 3 , Peru 12356 . 



Not received by us from Mexico ; there is a specimen (perhaps the one alluded to by 

 Mulsantj in Crotch's collection, from that of Chevrolat, so labelled, and this is the sole 

 authority for the occurrence in the Northern continent of this species. 



2. Neda marginalis. 



Neda marginalis, Muls. Spec. Col. Trim, secur. p. 277 x ; Monogr. Coccin. p. 197 2 ; Crotch, Rev. 



Coccin. p. 168 3 . 

 Neda flavens, Muls. Opusc. Ent. iii. p. 41 4 ; Monogr. Coccin. p. 197 5 . 



Hab. Mexico 123 , Ventanas in Durango, Chilpancingo in Guerrero, Jalapa (Hoge), 

 Omilteme 8000 feet, Amula 6000 feet (H. H. Smith), Misantla (Flohr), Cuernavaca, 

 Cordova, Orizaba, Oaxaca (SalU) ; Guatemala {Salle), Tepan (Conradt), Duenas, San 

 Geronimo (Champion) ; Costa Rica, Cache (Bogers). 



Crotch quotes 3 Brazil, but with doubt. I have seen no specimens of N. marginalis 

 from the Southern continent. The locality oi N. flavens was unknown to Mulsant 45 . 



Subfam. CHILOCOBIDES. 



This is one of the most natural divisions of the Coccinellidee, well characterized 

 by the front of the head forming a sort of clypeus surrounding the eye, and cover- 

 ing (in Chilocorus at least) the point of insertion of the antennae, which thus lie in 

 a fovea beneath it. The inner edge of the epipleurse of the elytra is also generally 

 divided behind the middle into two ridges, with a narrow channel between them 

 for the reception of the margin of the hind body, thus closing very effectually the 

 passage between it and the elytra. I do not find this character mentioned by authors, 

 but it exists in several of the genera I have at present studied. 



The species are distributed very widely over the whole world, Chilocorus alone being
