CHOLEVA. 



This genus seems to \m fairly well represented in Australia ; 

 although only two species have been described. Of these 

 C auMi'aJis, Er., may be distinguished from all other species 

 known to me by the following characters in combination : — Colour 

 and pubescence black ; mesosternum finely carinate ; prothorax 

 and elytra transversely strigose. C. obscurus, Macl., has not 

 been formally described — the only indication of its characters 

 being a statement (Tr. Ent. Soc. N.S.AV., IL, p. 155) that it 

 differs from C. australis in its pubescence being light coloured, 

 and its prothorax and elytra longitudinally, instead of trans- 

 Aersely, scratched or striolated. If it is to be inferred that the 

 prothorax is distinctly striolate longitudinally (in the same man- 

 ner that it is transversely in C. australis) I am confident that I 

 have not seen the insect ; if the reference be merely to the 

 slight longitudinally striolate appearance resulting (in many 

 species of the genus) from the direction of the adpressed hairs 

 which clothe the surface, there is nothing in the description whicli 

 would distinguish C. obscurus from any species (with one or two 

 exceptions) of Cholera known to me. In this latter case it is 

 impossible to describe any new species without running some 

 risk of re-naming Sir W. Macleay's insect ; subject to that re- 

 mark, the following appear to be new. It may be noted that in 

 the Australian species of Cholera having the mesosternum carinate 

 (so far as my own observation goes) the carina is not a strongly 

 elevated one like that of the European C. sericeus, Fab., but a 

 very line line running down the centre of the segment, and 

 usually becoming obsolete in the front part ; the front part, how- 

 ever, consisting of a sort of thickened transverse fold, which is 

 more elevated than the carina, although not truly carinate (as in
