A large species closely allied to C. colossus, Blackb., but of 

 wider and more ro'bust l)uild and more obscurely coloured. In 

 the unique specimen known to me of this insect the tarsal vestiture 

 has been much matted, and I have not been able to restore it very 

 satisfactorily. In its present condition the vestiture is of a pitchy- 

 black tone in general, but in places is distinctly fulvous, and I 

 have no doubt the tarsal vestiture in a fresh example is entirely 

 fulvous. Subject to the differences specified in the diagnosis 

 above, the diagnosis of C. colossus may be read as applying to 

 this insect.

C. LATICOLLIS, Sp.nOV. 



C. colosso affinis ; differt prothorace quam longiori (et postice 

 quam antice) fere duplo latiori, in medio quam ad basin 

 manifeste latiori ; elytrorum puncturis seriatis minus sub- 

 tilibus. [Long. 8-91, lat. 4i-44 lines. 



This species is nearer to colossus than I like, but the differences 

 seem to be of a kind that cannot but be specific ; indeed, the form 

 of the prothorax in the present insect (of which I have seen a 

 good many examples) is alone sufhcient to form a distinction from 

 every other Chalcopterus that I have seen, that segment being at 

 its widest at the middle and thence slightly narrowed to the base.

C. GRACILIOR, sp.nOV. 



C. Bovilli valde affinis ; corpore supra Isete cyaneo vel violaceo 



(capite obscuriori) certo adspectu viridi-tincto ; corpore 



subtus splendide metallico-iridescenti ; antennis (9 ?) quam 



corporis dimidium paullo breviori ; prothorace magis sub-
