separates the eyes from one another on the upperside of the 

 head. As minor points of difference may be noted the com- 

 plete absence of pubescence from the first joint of the antenna? 

 in both sexes and the presence of two tolerably distinct, 

 though short, spines between the anterior and posterior on 

 each side of the prothorax.

This fine species may be distinguished by the somewhat 

 trapezoidal form of the prothorax in both sexes. In the male, 

 as in the female, the outer margins of the pronotum, furnished 

 with a series of rather strong spines, distinctly converge 

 anteriorly, and each forms with the front margin a tolerably 

 acute and slightly projecting angle. In the male the pro- 

 notum is very closely and rather minutely punctured and 

 opaque, with a narrow transverse space at the base, a trian- 

 gular area on each side of the middle, and two smaller areas 

 external to it, sparsely punctured and more or less glossy. 

 In the female the pronotum has two slight swellings on each 

 side of middle of the disk ; it is sparsely punctured and sub- 

 nitid over the whole central area, but is somewhat more 

 thickly punctured and less nitid towards the sides. The 

 elytra are very minutely granular and only slightly glossy 

 over most of their surface, but are smoother and glossier 

 alongside the anterior part of the suture. 



Basitoxus rugosus, sp. n. 



Piceo-fuscus, fortiter subrugoseque punctatus ; tibiis omnibus apice 



extus spinosis. 

 <J . Lateribus pronoti subparallelis, breviter denticulatis ; disco 



basi et plaga utrinque prope medium sparse punctatis nitidis.
