Genera and Sjjeeies of Coleoptera. 335 



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

 will give a better idea than any description), a few bristly hairs fring- 

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

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

 joint, except at the apex, and last four joints white ; body beneath 

 pitchy, with a sparse silvery pile. Length 4 lines. 



Agelasta [Lamiidoe]. 



Newman, Entomologist, p. 288. 



Agelasta Mouhotii. 



A. cinereo fulvoque pubescens, nigro maculata; elytris fasciis duabus 

 fuscis ornatis ; tibiarum apice tarsisque nigris. 



Hah. Cambodia. 



Sparingly pubescent, the dark shining epiderm everywhere more or 

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

 dark brown on the latter ; the fulvous 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 fulvous 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 

 tibiae and the tarsi black; antennae scarcely longer than the body, 

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

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



This very distinct species, which is perhaps 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 Siam. 



Agelasta rwpta. 



A. obscure-griseo pubescens, nigro maculata ; elytris fasciis duabus den- 

 tatis nigris ; tibiis annulatis tarsisque nigris. 



Hub. Cambodia. 



Sparingly pubescent, dull greyish, spotted and banded with black ; 

 head yellowish grey, obscurely spotted ; antennae longer than the body, 

 the first two and basal half of the third joint grey, the remainder 

 black, with the fourth, sixth, eight, tenth, and eleventh at their bases 

 more or less ashy ; prothorax very short and transverse, yellowish grey, 

 spotted with black; scutellum nearly quadrate, the apex slightly 

 rounded ; elytra short, subparallel, irregularly punctured, greyish, a 

 toothed band between the base and middle, and a narrower waved in-
