are flat, and finely but not closely punctured ; lateral 

 margins reflexed ; underside deep shining black, finely 

 punctured, pubescent ; legs yellow, with the apical half 

 -of all the thighs, and the base and apex of all the tibiae, 

 black ; palpi, and three first joints (save the tip of the 

 third) of the antennae, reddish ; tips of the former dusky, 

 remaining joints of the latter black; tarsi dusky red. 



The hind thighs are strongly compressed, and are ex- 

 panded in the middle within, into a very broad blunt 

 tooth ; the tibite are all strongly keeled externally, the 

 anterior feebly sinuous, the posterior very strongly 

 sinuous or twisted, completely excavated or channelled, 

 on their inner side, from near their base, and expanded in 

 the middle ; these characters, together with the more 

 projecting* eyes, the smaller and narrower form, brighter 

 colours, sparser pubescence, and the elytra gradually 

 attenuated behind, are the distinguishing features of the 

 males in this genus. 



The present species may be at once separated from 

 C. picta (Pascoe, Journ. Ent. ii. 491) by its smaller size, 

 more prominent eyes, squarer prothorax, finer punctua- 

 tion, and differently coloured labruni, antennae, legs, and 

 elytra.

I have great pleasure in dedicating this handsome 

 little species to my friend F. P. Pascoe, Esq.

$. Length 3 1 lines: — very similar in colour, mark- 

 ings, &c., to the preceding, but the black of the pro- 

 thorax and elytra is somewhat dusky, and with a slight 

 greenish tinge ; it is also a little larger ; the eyes are 

 less prominent, the head broader, the prothorax shorter, 

 broader, rounded at the sides, decidedly narrowed an- 

 teriorly, the hind angles more strongly rounded, and 

 the punctuation of the whole insect, both above and 

 on the underside, is coarser. 



The $ is more pubescent than the S ; the black of 

 the prothorax and elytra of a duskier hue, and with a 

 more decided greenish tinge ; the eyes less prominent ; 

 the elytra broader, and gradually expanding to the 

 middle, with the yellow stripe broader and extending 

 nearer to the apex ; the tibiae are keeled only at the
