77. HELiEUS HoPEi, Brenie. 



Mon. Cossyph. I. p. 68, pi. V. fig. 4. 



Oval, dull black ; head rounded and rugose, clypeus not emar- 

 ginate, separated from the epici'anium by a deep transverse groove; 

 labrum rounded and salient. Antennoe scarcely the length of the 

 thorax, rugose and hairy, the four last joints round. Thorax 

 transverse, narrowed in front, convex, sinuate behind, strongly rugose 

 and carinate, the median line elevated into a carina, the margins 

 not reflexed all round, broad particularly towards the posterior 

 angles which are acute and feebly recurved, the anterior angles touch 

 only and are thin and very pointed. The elytra narrow slightly on 

 the sides towards the apex and terminate in a slight point ; they 

 are rugose, with numerous slightly visible costpe, the disk is convex 

 at the base and flattened towards the apex ; on each elytron and 

 about the middle of its breadth is a strongly salient costa, longi- 

 tudinally rounded, which extends from the base to two-thirds of 

 the length, where it is obliterated and approaches the suture, the 

 suture is not sensibly elevated, the margin is as large as that of the 

 thorax at the humeral angles and is almost reduced to a simple 

 reflected boi'der posteriorly on each side. Legs and under surface 

 dull black.

 group to which the two following species belong.

" Oblong, parallel at the sides, impunctate, rusty-brown, opaque, 

 sparsely covered with fulvous hairs simulating scales ; head a little 

 prolonged anteriorly ; clypeus rounded ; prothorax rather trans-
