232 MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. [May 8, 



Covered above with a short dense reddish-grey pubescence varied 

 or marbled with brown ; head minutely punctured, the mesial line 

 extending to the lip ; prothorax transverse, rounded at the sides, 

 rather finely punctured ; scutellum rounded behind ; elytra broader 

 behind the middle, the punctures larger than those on the prothorax, 

 and very irregular, the brown mottling the whole of the elytra in a 

 very indefinite manner, but forming posteriorly an oblique zigzag 

 line, anterior to which, but behind the middle, is a large brown well- 

 marked spot ; body beneath dark chestnut, the sides of the abdomen 

 densely clothed with a rich-reddish-brown pile ; legs covered with a 

 delicate rosy pubescence, banded with dark brown, the two basal 

 joints of the tarsi entirely rosy, the third and fourth varied with 

 brown ; antennae longer than the body, also with a short rosy pu- 

 bescence, the four basal joints spotted, and at their tips, as well as 

 the tips of the remainder, ringed with browu. Length 7 lines. 



Not to be distinguished generically, as it appears to me, from the 

 Mesosa curculionoides of Europe. It is a very distinct species from 

 the M. perplexa of China.

Dark brown, the pubescence brownish grey mingled with spots 

 and patches of dark brown and white; head glabrous in front (from 

 abrasion ?), black, finely punctured, a patch of whitish pubescence 

 under the eye ; prothorax transverse, scarcely broader than the head, 

 finely corrugated, the pubescence very slight and mostly brownish 

 grey ; scutellum small, rounded posteriorly ; elytra with a slightly 

 elevated granular line on each side at the base, the punctures very 

 small and partly concealed by the pubescence, behind the middle a 

 series of white spots forming an indefinite band, nearer the apex a 

 similar band but narrower, the rest greyish, with dark spots ; body 

 beneath and legs with a slight greyish pile ; the knees and ends of the 

 tibiae black ; tarsi ashy, bordered with black ; antennae ( $ ) as long 

 as the body, black, the third and fourth joints (except at the tips 

 and their tufts) ashy, scape nearly glabrous, finely punctured. 

 Length 8 lines. 



A fine and very distinct species. 



Cacia pistor.
