represented almost everywhere ; I have not, however, seen examples of it from further 

 south in America than Brazil. Exochomus has one representative in Europe, IE. nigro- 

 maculatus, which is, perhaps, the most widely distributed of any species of the family, 

 being found from Northern Europe to the Cape of Good Hope, and from Siberia to 

 Australia, yet, strangely enough, it seems to have disappeared from England. 



Crotch has included Platynaspis in the Chilocorides, and that genus agrees with the 

 rest of the subfamily in the structure of the clypeus, and on this ground I include 

 Corystes ; but some other genera (as, for instance, the Eastern Cryptogonus) are much 

 more nearly related to the Hyperaspides, the presence of a seventh abdominal segment 

 in the male externally, depending very much upon its extrusion or otherwise, being no 

 doubt present, though possibly modified, in both subfamilies. Cryptogonus is indeed 

 treated by Weise as congeneric with Hyperaspis.

CMlocorus is a genus of about thirty-five species, distributed all over the world. 

 One species has lately been described from Australia, but CMlocorus has hitherto been 

 considered to be represented by the allied genus Orcus in that continent. Two species 

 are found within our limits.
