whiter scales predominant and with moderately long and 

 slender cinereous hairs over the entire surface. Head 

 ver}^ sparsel}' coarseh^ punctate. Thorax nearly a half 

 wider than long, broadest at middle, sides regularly arcu- 

 ate, a feeble post -apical constriction, surface very indis- 

 tinctly coarsely punctate. Elytra oval, the sides parallel 

 for a short distance, humeri rounded, disc finely punctato- 

 striate, intervals flat, irregularly biseriately punctate, each 

 puncture with an erect hair. Body beneath with paler, 

 less dense scales and with shorter hairs. Legs moder- 

 ately densely scaly and with long hairs. Length, .20 

 inch; 5 mm.

 versal in this part of the Otiorhynchide series.

Form elongate, resembling in facies a diminutive Per-

 scales and with an irregular row of short whitish hairs on 

 each interval. Beak longer than the head, longitudinally 

 plicate, eyes surrounded by a groove, scrobes terminal, 

 vague. Scape of antennae passing slightly the apex of 

 thorax, shorter than the funiculus, the first two joints of 

 which are moderately long and equal. Thorax wider 

 than long, sides regularly arcuate, a feeble post-apical 

 constriction, disc convex, coarsely deeply and closely 

 punctate. Elytra oblong-oval, nearly twice as long as 

 wide, with regular rows of moderately coarse and closely 

 placed punctures, the intervals flat and more than twice 

 as wide as the strice, the scales narrow, semi-erect and
