and with obsolete scutellar impression of the elytra ; the abdomen 

 is not margined at the sides with denser pubescence. Length 6.5- 

 6.8 mm. ; width 2.5 mm. 



13 L,. pygmaeus n. sp. — Elongate, elliptical, moderately slender, convex, 

 polished, black throughout, the tarsi rufo-piceous ; antennae rufous with darker 

 club ; vestiture short, sparse, feebly mottled on the elytra. Head convex, 

 finely punctate ; beak slender, cylindrical, strongly arcuate, finely, densely 

 punctate, more strongly so in the male, in the latter sex very short, not quite 

 as long as the prothorax, much longer in the female, the scrobes extending 

 rather beyond apical third in both sexes. Prothorax short, one-half to two- 

 thirds wider than long, the base much wider than the apex and broadly, 

 feebly cusped in the middle ; apex truncate ; sides strongly convergent from 

 base to apex and rather strongly arcuate ; disk with a small feeble basal im- 

 pression, finely, feebly, sparsely punctulate and with coarse remote variolate 

 punctures, denser at the sides where there is a very narrow feebly marked 

 line of denser pubescence. Elytra twice as long as wide, just visibly wider 

 than the prothorax, rather narrowly parabolic at apex ; sides parallel and 

 very slightly arcuate especially behind ; disk with a broad and feeble scutel- 

 lar impression and with completely unimpressed rows of distant punctures, 

 which are coarse toward base but gradually very fine toward apex ; intervals 

 extremely minutely, feebly, sparsely punctulate. Abdomen more densely 

 clothed with longer hair. Legs short but rather slender, sparsely pubescent. 

 Length 5.0-6.2 mm. ; width 1.8-2.2 mm. 



Kansas. - 



The single pair before me indicates a species somewhat allied to 

 musculus, but with more arcuate and less densely punctured beak 

 and more coarsely and remotely punctured pronotum, the latter 

 being only impressed near the base ; the size is very much smaller, 

 it being in fact the smallest species known to me from our fauna.

New York to Idaho. A rather large species, not very densely 

 and nearly evenly clothed with very short robust hairs, and gener- 

 ally densely covered with yellow pollen. The prothorax is broadly 

 impressed along the middle, strongly so near the base, and is from 

 one-third wider than long to nearly as long as wide. The beak is 

 rather longer than the prothorax in the male and much longer in 

 the female, the antennae inserted at apical third. The female, 

 although larger than the male, is relatively more slender, and the 

 type of rectus is an unusually small specimen of the former sex, in 

 which the prothorax is only slightly wider than long, but com-
