Varies from reddish brown to brownish black in colour ; head 

 and prothorax sparsely coA'ered with tawnj"^ pubescence ; elytra 

 with tawny or asby-grey pubescence, or with pubescence which is 

 partly ashy-grey and partly tawuy, somewhat variable in its 

 distribution, but with a marked tendency to arrangement in 

 longitudinal series of sublinear spots ; body beneath, legs, 

 and antennae entirely covered with tawny or grey pubescence. 

 Antennae extended to the posterior third of the elytra in the c? 

 and to their middle in the $ ; tirst joint reaching to a little past 

 the hind margin of the eye ; fifth to tenth angulate anteriorly at 

 the apex. Prothorax a little longer than broad, strongly and 

 irregularly rugose above and at the sides, marked with a trans- 

 verse groove near the apex and a bisinuate groove near the base ; 

 the disc with scattered patches of tawny pubescence. Elytra 

 densely punctate ; each truncate at the apex, with the outer angle 

 acute or subdentate, the sutural angle spined.

Very like R. simulans. White, in general appearance, but distin- 

 guishable from it by the following characters : — Elytra generally 

 rounded, sometimes subtruncate, at the apex, but without external 

 tooth or angle, and with only a very short spine at the suture. 

 Pronotum somewhat less strongly rugose and less sparsely 

 pubescent than in li. simulans, its length scarcely greater than 

 its width across the middle. 



Length 20-27i ; breadth 5-7 mm.

Eyes large, deeply emarginate, not extending to a line with the 

 antenual condyles in front, rather closely approximated above, with 

 the narrow space between them n:iarked with a feeble median 

 carina. Antenna? scarcely or not at all longer than the body in 

 the $ , a little longer in the S ; fifth to tenth joints sharply edged 

 in front and acutely angulated at the apex ; eleventh only a little 

 longer than the tenth. Prothorax strongly rugose, a little longer 

 than broad, rounded at the sides, constricted and transversely
