recumbent pubescence easily removable, and leaving merely a minute super- 

 ficial scar. Prosternum not distinctly punctate, minutely, feebly scabrous and 

 alutaceous, the median groove deep but narrow ; episterna transverse, short, 

 the inner marginal line distinct, broadly arcuate ; metasternum with the per- 

 forate punctures about equal in size to those of the elytra, and separated by 

 about three times their own widths. Abdomen dull, excessively minutely, 

 densely pubescent, the perforate punctures completely wanting. Legs mode- 

 rate ; intermediate tarsi short, about one-half as long as the tibiae, but with 

 the second joint rather longer than wide. Length 1.5 mm.

In its entirely impunctate abdomen this species differs from any 

 other of the subgenus ; it somewhat resembles ovatiis, but differs 

 in its more elongate form and in its coarser elytral punctures, these 

 being about twice as large as in that species. The longer hairs of 

 the elytra in ovatus are longer than in navicvlatus, and the short 

 oppressed ones much sparser. In ovatus there is no trace of macu- 

 lation, whereas in the present species the pubescence is paler at 

 three indefinite lateral spots on each elytron, giving, under extremely 

 low power, the appearance of three imperfect transverse fascia? ; in 

 the former the intermediate tarsi are nearly two-thirds as long as 

 the tibiffi.

 gradually pointed behind, nearly twice as long as wide, widest near the 

 middle, piceous-brown, very densely pubescent ; integuments shining. Head 

 finely and very sparsely punctate. Prothorax more than twice as wide as long; 

 sides straight ; apex two-thirds as wide as the base ; median lobe small, dis- 

 tinct ; median groove obsolete ; surface shining, very feebly reticulate near the 

 sides, not very coarsely, very sparsely punctate, with the interspaces much 

 more minutely, densely punctate. Scutellum small, slightly longer than 

 wide, feebly convex, densely pubescent ; sides and base feebly arcuate. Ehjtra 

 about three and one-half times' as long as the prothorax ; sides distinctly 

 arcuate and nearly coarctate with those of the prothorax, the humeri almost 

 impunctate and slightly, longitudinally tumid ; surface rather coarsely, 

 sparsely punctate ; punctures perforate and separated by from three to four 

 times their own diameters ; interspaces polished, the minute recumbent hairs 

 not arising from definite punctures. Prosternum shining, minutely and not 

 very densely punctate, much more densely punctate and alutaceous anteriorly ; 

 median groove fine, extending nearly to the apex ; episterna short, broadly 

 triangular, clearly limited within throughout, 'the inner margin arcuate ; 

 hypomera flat, not impressed, minutely, densely reticulate, dull, minutely, 

 densely pubescent, not visibly punctate ; inner bead wide, flat, polished ; edge
