DESCEIPTIONS OF NEW CUCUJIBM AND CLEEID2E. 

 BY CHAS. O. WATEEHOUSE. 



GUCJJJIBM. 

 HECTARTHEUM. 



I have had occasion to examine the numerous specimens of this 

 genus iu the British Museum, but I regret to say with no very satis- 

 factory results. Among them, however, I find a few tolerably well- 

 defined species, which are at present undescribed, and of which I 

 subjoin diagnoses. The species may be tabulated as follows ; it 

 being understood that the humeral stria reaches from the shoulder 

 nearly to the apex ; the dorsal stria is close to the humeral stria, but 

 nearer to the suture ; the lateral stria is midway between the humeral 

 stria and the margin. All the species have a sutural stria wliich joins 

 the marginal stria at the apex. 



I. Anteniiffi with the 3rd to 10th joints notched at their apex below. 



A. Elytra with humeral stria only well-defined. 



a. Femora and apical spot to the elytra red (W. Africa) . 



Thorax distinctly broader in front ffiffas, Fab. 



Thorax very little „ „ „ ciirfijoes, lUc-wm. 



h. Uniform black, naiTOW (Java) bistriatmn, G&i-,t. 



B. Elytra with humeral stria, and a very short dorsal stria. 



a. Frontal furrows closed in front ; channel on the 



under-side of the head near the base of 

 the antennae turned away from the eye 

 posteriorly (India) depressum, Sm. 



b. Frontal furrows more or less open in front ; chan- 



nel below the head extended to the eye.
