Allied to 2\ lot or, but with the arraBgement of color-

 elytris maculis magnis cinereis sex ornatis, apicibus

Black, minutely pubescent, the ashy portions formed 

 by a stouter pubescence ; head ashy, except the mesial 

 groove and stripe behind the eye, lip with yellow hairs ; 

 prothorax ashy, the central and a broad stripe on each 

 side black ; scutellum transversely elliptical ; elytra with 

 a large ashy spot at the base on each side the scutellum, 

 another at the side and directly before the middle, and 

 an irregular squarish spot, nearly meeting its fellow at 

 the suture between the middle and apex, the apices 

 clouded with ashy white, which is not well defined ante- 

 riorly ; body beneath glossy black in the middle, the sides

 ribus, fciscia irregulari prasapicali cinerea excepta ;

Hah . — Makian . 



Brown, covered with a very thin ashy pubescence, 

 which "v^nth the derm gives a dark leaden hue to the 

 whole upper surface, exce]it that the head is more de- 

 cidedly ashy, and a small irregular band near the apex, is 

 also ashy ; body beneath ashy, the middle line glabrous, 

 brown ; antennse and legs pure luteous. 



Length 8 lines. 



I was at first inclined to regard this species as a variety 

 of the last, but in addition to the apparently decided dif- 

 ferences of colour, there are also other slight variations 

 in regard to puncturation, convexity, &c.
