■white or wliitisli. On the upper surface the white sci.les are 

 poattercd siiiirly on tlie head atul rostrum, condensed into a 

 fechle line on each side of prothorax, form a distinct spot 

 on each side of scntcllnm, and some very feeble ours else- 

 wlierc. Tlic shouklers are ratlier strongly rounded, so that, 

 althouiili the elytra at their widest are distinctly wider than 

 the prothorax, their outlines appear to be almost continuous 

 •with those of that segment. The lower surface of each of 

 the four front tibise appears to have three distinct equal- 

 sized teeth : one in middle, one near and one at apex, but 

 the latter one is the terminal hook.

Rostrum moderately long, parallrd-sided, with dense, 

 clearly defined punctures in front of antennai ; behind same 

 coarser, sublineate in arrangement, but concealed towards 

 base ; with a narrow median carina. Scape inserted about 

 two-fiftlis from apex of rostrum, and distinctly shorter than 

 funicle ; first joint of funicle stouter and longer than second. 

 Prothorax moderately transverse, and punctures normally 

 almost concealed. Elytra subcordate, base strongly tri- 

 sinuate, with rows o£ suboblong, partially concealed punc- 

 tures, interstices nowhere ridged. Abdomen with basal 

 segment somewhat flattened, but the middle of its apex with 

 a narrow but distinct tubercle; apical segment with a large 

 shallow depression. Femora stout, rather lightly dentate ; 

 front tibiae subfalcate, lower surface somewhat grooved, 

 apical hook unusually strong. 



Length 2^-3 mm. 



? . Differs in having the clothing less variegated, rostrum 

 somewhat thinner and with smaller punctures, abdomen
