 Long., 3 1. ; lat., 1^1. 



A remarkable insect, with no near ally among described 

 species ; it might perhaps be regarded as the type of a new genus. 

 In some of its characters it agrees with Cleptor.

0. ccelestris, sp. nov. Sat fortiter convexus ; sat nitidus ; supra 



coeruleus, viridi violaceoque micans ; subtus niger — antennis, 



tarsis, tibiis anticis et abdomine testaceis ; capite sparsim 



subtiliter, prothorace subtiliter minus sparsim, elytris sat

(vix). 



A very pretty species, resembling in colour 0. cyanocephalus, 



Muls., and chalybeus, Boisd., but scarcely so convex as either of 



those insects, and much more strongly and closely punctured 



than either of them, or than 0. Australasice, Boisd. From 



0. cyanoceplialus it differs also in the colour of the legs, and from 



0. chalyheus in the more strongly rounded sides of the prothorax. 



0. Lafertei, Muls., I have not seen, but it appears to be a larger 



insect, of somewhat similar 'colour, but having some conspicuous 



violet spots symmetrically arranged on the prothorax.
