4. Chromomcea rufescens, n. sp. 



?. Length 4| lines: — shining; sparingly clothed 

 with a very short, fine pubescence ; labrum black ; head 

 and prothorax (flanks included) dark castaneous, with an 

 obscure line down the centre, and a marginal patch at 

 each side^ black ; elytra reddish-brown, with the apex 

 more or less dusky-black ; head strongly and rugosely 

 punctured ; prothorax a little longer than wide, sides 

 sub-parallel, slightly narrowed in front ; closely and 

 rather finely punctured, at each side of the usual basal fovea 

 is a small narrow elongate depression, close to the hind 

 margin ; hind angles narrowly rounded ; scutellum trans- 

 verse, broadly rounded behind ; elytra rather broad, de- 

 pressed; punctate-striate, the stria3 a little fainter at the 

 sides^ base J and apex ; intervals sub- convex, punctured^ 

 and more or less transversely wrinkled ; body beneath, 

 save the metasternum which is partly of a bright red, 

 black; finely pubescent, very glossy; middle joints of 

 abdomen bright red, remainder pitchy ; antennse red, 

 the three basal joints being paler; basal half of thighs, 

 and the tibia?, yellowish-brown ; ti]3s of the latter, and 

 apical half of the former, red ; their tips, and the tarsi, 

 darker. 



The terminal joint of the antennee is smaller than the 

 preceding, and is somewhat acutely pointed at the apex. 



In the two female examples of this species before me, 

 one has the head darker, the prothorax more obscured 

 by dusky patches, and more depressed, the sides more 

 parallel and less contracted in front, and the basal callo- 

 sities of the elytra much less pronounced, than in the 

 other. I do not know the male. The larger size, and 

 nearly uniform reddish-brown colour, will serve to dis- 

 tinguish this species from any of the foregoing.

 ashy pubescence ; somewhat strongly depressed ; head 

 rather narrow, strongly punctured ; the punctures, be- 

 hind the eyes, elongate ; prothorax a little longer than

 hind angles scarcely, or very narrowly, rounded ;
