as wide, and subequal to the next two. Head densely punctate, 

 front concave, ^vertex finely carinate. Beak moderate, striate 

 and punctate as usual. Prothorax moderately transverse, sides 

 arcuately subparallel basally, surface densely punctate, median 

 channel distinct, deeper behind, lateral tubercles obtuse. Elytra 

 distinctly longer than wide, broadly arcuately narrowed posteriorly; 

 strise fine; intervals broad, fiat, each with three or four more or 

 less irregular series of small, hair-like scales. Legs moderate, 

 thighs unarmed, feebly annulate with whitish scales. Claws 

 with a rather small but acute basal tooth. 



Length 2.9 mm.; width 1.75 mm. 



Corvallis, Oregon, (Moznette). 



The type is a male, having the last ventral distinctly foveate, 

 and the middle and hind femora unguiculate. 



This species must be placed near mntabilis Dietz. The latter 

 is a smaller species, with coarser, less appressed vestiture, the 

 broader scales of the upper surface much more numerous. 



Ceutorhynchus convexipennis, n. sp. 



Oval, black, moderately shining, thinly clothed above with 

 short, white appressed hairs which are somewhat coarser on the 

 elytra, where they are disposed in nearly single series on the in- 

 tervals, as well as in the striae. Antennae entirely piceous, funicle 

 7-jointed, first and second joints subequal in length, following joints 

 gradually shorter. Beak rather slender, evenly arcuate, shining, 

 sparsely punctate and lightly striate at sides basally; more sparsely, 

 finely and irregularly punctate above and apically; antennae in- 

 serted at about the middle ( 9 ?). Head densely, evenly punctate. 

 Prothorax coarsely, densely punctate, the punctures round and 

 nearly in mutual contact; base much wider than the apex, sides 

 parallel in nearly basal half, broadly constricted apically, anterior 

 margin not emarginate, lateral tubercles small, acute. Elytra 

 sub-oval, strongly convex, two-sevenths wider than the prothorax 

 and a little more than one-fourth longer than wide, widest at 

 basal fourth; striae moderate, intervals a little wider than the 

 striae, only slightly convex, surface feebly rugose, some small, 

 acute granules on the declivity. Body beneath coarsely, closely 

 punctate, each puncture bearing a white scale, the scales a little
