The whitish-grey pubescence of the upper surface is dense and 

 extensive enough to give the appearance of the general surface 

 being almost white, the non-pubescent parts looking like black 

 markings. The non-pubescent parts are mostly elevated, but the 

 one of them that is largest in area (a wide ante-median fascia on 

 the elytra, widest on the margin and much interrupted at the 

 suture) is on the level of the general surface ; this non-pubescent 

 part is coarsely rugulose, the rest being Itevigate or nearly so. 

 The elevated non-pubescent spots consist of a number of small 

 granules protruding through the pubescence on the sides of the 

 prothorax, a short longitudinal ridge on the middle line of the 

 prothorax (entirely in the basal half), with an irregular, somewhat 

 lunate ridge on either side of it (these lunate ridges longer than 

 the central one and not quite glabrous), and a number of spaces 

 on the elytra resembling obtuse feebly-elevated tubercles, some of 

 those in the hinder half being very much larger in area than the 

 rest, and having a diameter scarcely less than a third of the 

 width of the elytron. As in the preceding species the derm 

 near the apex has more or less tendency to a reddish tone of 

 color. In the examples before me the pubescence on the head is 

 patchy, and in parts thin ; this may be due to abrasion. Joints 

 3-7 of the antennae are distinctly spined. 



This species is at once distinguished from most of its congeners 

 by the bi-spinose emargination of the apex of the elytra (thougli 

 the sutured apex is an angle rather than a well-defined spine) ; 

 and by the form of the prothorax, the sides being nearly straight 

 from close behind the front to behind the middle, and then con- 

 verging from a fairly well-defined angle somewhat sinuously to
