This is a small species of metallic-green colour, with light-flavous legs ; the thorax 

 is simply angulate behind the middle, very finely punctured ; and the elytra are distinctly 

 and rather regularly punctate-striate ; the basal portion is transversely depressed, and 

 the punctation there as well as at the sides much stronger ; the posterior knees are 

 generally piceous.

Hob. Mexico, Cordova (H'oge). — Colombia 1 . 



Two specimens from Mexico are before me which I must refer to M. Lefevre's 

 species, although with some degree of uncertainty, as the type must be compared. In 

 these Mexican specimens there is a distinct basal depression of the elytra ; in other 

 respects they agree with the description. 



16. Colaspis subcostatus. 



Subelongate, obscure dark rufous or piceous ; legs light fulvous ; thorax angulate at the sides, closely punc- 

 tured ; elytra geminate-punctate-striate, the interstices costate. 



Length 2|-2| lines. 



<J . Head longitudinally depressed at the vertex, closely and finely punctured ; clypeus more or less distinctly 

 separated by a transverse groove ; labrum narrow, testaceous ; antennae testaceous, the terminal joints 

 more or less stained with fuscous ; thorax twice as broad as long, the sides reflexed-marginate, angulate 

 behind the middle, surface closely and finely punctured, but more strongly towards the base ; elytra 

 obsoletely depressed below the base, distinctly and rather strongly geminate-punctate-striate, the punc- 

 tuation less strong and arranged in single rows towards the apex, where the interstices are slightly 

 costate ; underside obscure rufous, more or less stained with piceous ; intermediate tibiae curved. 



§ . Larger, of a lighter fulvous colour, especially the thorax, the latter obsoletely bisinuate at the sides ; elytra 

 with a metallic greenish tint, the interstices throughout raised into longitudinal costae; underside and 

 legs fulvous ; intermediate tibiae but slightly curved.

1 have but little doubt that the four specimens obtained by Mr. Champion represent 

 both sexes, although the differences in colour and sculpture are rather strongly 

 expressed. The tarsi in the males are, as usual, strongly dilated, those of the females 

 normal. C. inquinata, Lefev., seems to be an allied species, but differs in the strong 

 and distant punctuation of the thorax, and in its smaller size. The male of the present 

 species is of a dark bronze or piceous colour; its longitudinal elytral costse are 

 only indicated ; its thorax is more distinctly dentate at the sides, while that of the
