Pubescent, deep black, varied with a nearly pure white (the figure

 ing the sides of the elytra; tarsi brownish, and the terminal joint 

 yellowish white ; antennre slightly ciliated beneath, black, the fourth

Ayelasta Mouliotn. 



A. cinereo fidvoque pubeseens, nigro maculata ; elytris fasciis duabus 

 fiiscis oruatis ; tibiarum apice tarsisque nigris.

Sparingly pubescent, the dark shining epidei-m everywhere more or 

 less visible ; head and prothorax with a thin fulvous pile, spotted vnih. 

 dark brown on the latter ; tlie fidvous passes into ashy posteriorly, and 

 is continued on to the scutellum and base of the elytra, where it is 

 limited by a broad band of dark brown, having its posterior border 

 very irregular ; the rest of the elytra is fidvous with a denticulate band 

 towards the apex ; and the whole, not occupied by the two bands, is 

 dotted with small brown or nearly black spots, the centres of each 

 being occupied by a shallow puncture ; legs ashy, the lower half of the 

 tibii© and the tarsi black ; anteunte scarcely longer than the body, 

 black, the first three, base of the fourth, and the fifth joints ashy ; body 

 beneath -svith a thin ashy pile. Length 5-6 lines. 



This very distinct species, which is perliaps most nearly connected 

 with A. amicus, Wh., may be recognized by the clear ashy-grey at 

 the base of the elytra, contrasted with the rich-dark-brown band 

 which succeeds. I have dedicated it to M. Mouhot, who, as is well 

 known is now, and has been for some years, investigating the Zoo- 

 logy of Cambodia and Siara.
