Deretiosus aspratilis, n.sp. 



(J. Densely covered all over (except apex of rostrum and a 

 space between front coxae) with pale fawn-coloured scales, paler 

 on head, rostrum and under surface than elsewhere. Prothorax 

 scarcely fasciculate, but with a number of very stout, erect scales, 

 especially towards the apex. Each elytron with a strong fasci- 

 culate crest on 3rd interstice, commencing at base and terminat- 

 ing before middle, the scales composing it being large, wide and 

 fluted throughout, shoulder with a small fasciculate crest, a 

 number of stout scales arising elsewhere and marking the posi- 

 tions of feeble fascicles. 



Rather narrow, moderately convex. Rostrum almost straight, 

 sides feebly incurved to middle. Antennae slender; scape about 

 the length of funicle, inserted in exact middle of rostrum; 1st 

 joint of funicle obtriangular, longer than 2nd, the 7th apparently 

 soldered to the club and causing it to appear elongate-elliptic. 

 Prothorax strongly transverse, sides not suddenly dilated and not 

 elevated, apex produced and fully half the width of base, base 

 trisinuate, disc somewhat uneven. Scutellum transverse. Elytra 

 raised above and not much wider than prothorax, base strongly 

 trisinuate, shoulders produced and rounded, sides parallel to near 

 apex; striae scarcely traceable. Femoral teeth moderately large 

 and acute, the intermediate smallest, the posterior longest and 

 very acute; tibiae very short. Length 5 J, rostrum 1J (vix); 

 width 2J mm.

In another specimen the elytra at the summit of the posterior 

 declivity are marked with a transverse narrow whitish fascia and 

 several small whitish patches along suture. The apparently 

 6-jointed funicle is not due to accident, as it is exactly the same 

 in the two specimens under examination; the 7th joint is clothed 

 like and appears to be truly a part of the club. This and the 

 two following species are narrower and less depressed than the 

 two preceding, and the prothorax is somewhat differently shaped.
