pletely similar in every other detail of structure. The male asso- 

 ciated with the female type of rectus is a normal male of concavus. 

 Length 9.5-13.8 mm.; width 3.0-4.6 mm.

Indiana ; Illinois. This species is about as long as concavus 

 and distinctly more robust, also with a shorter, stouter beak, in 

 which the sexual differences are much less pronounced. The vesti- 

 ture is cinereous, extremely short, moderately dense, almost evenly 

 distributed and squamiform, and it may be distinguished at once 

 from concavus, not only by this character, but by the feebly ele- 

 vated rostral carina. The prothorax is almost identical in outline 

 with that of concavus but is a little shorter. Length 12.0-15.3 

 mm. ; width 3.8-5.2 mm.

16 Ii. SOror n. sp. — Rather robust and convex, parallel, moderately shin- 

 ing, black throughout, the antennae piceous ; vestiture yellowish, dense, feebly, 

 coarsely mottled on the elytra, very short, somewhat dense, squamiform ; sur- 

 face densely pollenose. Head and beak finely but strongly, evenly, moderately 

 densely punctate, the beak in the female slender, rather arcuate, cylindrical, 

 shining, very slightly longer than the prothorax, the antennae inserted at two- 

 fifths from the apex. Prothorax one-fourth wider than long, the apex trun- 

 cate, three-fifths as wide as the base, the latter broadly, distinctly, angularly 

 lobed or cusped in the middle; sides visibly convergent and feebly arcuate 

 from the base, rather abruptly narrowed or constricted in apical fourth ; disk 

 with a large deep ovoidal impression extending from the base to apical fourth, 

 the sculpture feebly rugulose and consisting of moderately coarse and finer 

 punctures densely intermingled, the pubescence denser laterally and in the 

 depression. Elytra more than twice as long as wide and between three and 

 four times as long as the prothorax, subequal in width to the latter, rather 

 obtusely ogival and minutely notched at apex ; sides parallel, nearly straight ; 

 disk broadly, strongly impressed in the middle at base, having rows of moder- 

 ately coarse distant punctures, the intervals minutely, densely, indistinctly 

 punctulate. Abdomen rather densely clothed with longer pubescence. Legs 

 short but not very robust, sparsely clothed with short pubescence. Length 

 10.5 mm. ; width 3.6 mm.

Allied to concavus but diverging in many decisive characters, 

 among which may be mentioned the shorter beak of the female and 

 the difference in form, depth and extent of the pronotal impression. 



17 L.. laramiensis n. sp. — Rather stout, parallel, somewhat depressed 

 above along the middle, black throughout, the antennae scarcely paler; integu-
