1208 COLEOPTERA 



more or less squamose grooves separated by three carinse, the sides 

 also carinate. Scrobes deep in front, quite easily seen from above, 

 and prolonged along the sides of the rostrum to below the eyes, but 

 becoming shallow on reaching these organs. Scape flexuous, apex 

 clavate ; funicle 7-articulate ; second joint elongate, as long as but 

 more slender than first, joints 3-6 transverse, seventh larger than 

 the preceding one ; club short and compact, ovate. Eyes rotundate, 

 distinctly facetted, placed not on the sides, but on the upper part of 

 the head, and therefore more approximated than is usually the case 

 in allied genera ; moderately distant from thorax. Thorax truncate 

 in front, bisinuate at base, a little constricted near apex, without 

 ocular lobes. Scutellum invisible. Fdytra widest behind the pos- 

 terior femora, gradually narrowed to width of thorax at base. Pro- 

 sternum widely but not deeply incurved in front. Ahdovien large, 

 basal two segments connate, second larger than first, their suture 

 oblique towards the sides but very feebly marked, third and fourth 

 very short. Legs rather elongate ; tibiae flexuous, mucronate ; tarsi 

 short, their soles almost sponge-like, third joint hollowed out above 

 but not lobate. 



The position of the eyes, the peculiar scrobes, and strongly 

 carinate rostrum are distinctive. 



213o. D. duniGtOSUS, «•■■*• Subovate, elongate, convex, 

 opaque ; smoky-black, antennae and tarsi rufo-piceous ; sparingh' 

 clothed with small, elongate rather than round, greyish-yellow 

 scales, but near the sides and hind part of elytra with very coarse, 

 upright, pale-brown, squamiform setae. 



Rostrum longer than thorax, with four obvious grooves, having 

 slender grey scales in them, extending from the eyes to point of 

 antennal insertion. Thorax barely as long as broad, somewhat con- 

 stricted in front, sides a little rounded ; with an abbreviated median 

 carina, distantly and moderately punctured, in front of the base at 

 the middle slightly depressed, and having about ten or twelve tuber- 

 cular elevations on the back part of the disc ; the coarse setae form 

 three tufts on each side, two smaller ones on the apex, and two 

 others a short distance behind these. Elytra depressed at the 

 scutellar region, gradually widened as far as the hind thighs ; with, 

 on each elytron, four rows of large shallow depressions or coarse 

 punctures not extending more than two-thirds of the whole length, 

 behind these impunctate, but with a few obsolete striae near the 

 apex ; on the punctate portion there are several small tubercular 

 elevations, besides others on the sides ; the coarse setae are most 

 conspicuous behind, where they form nearly twenty small tufts. 

 Legs and tarsi with some line greyish scales ; tibias, particularly the 

 anterior, much bent, their extremity oblique. 



Underside piceous ; second abdominal segment quite impunctate 

 on the middle, apical one moderately closely punctured.
