500 Memoirs on the Coleoptera 



punctures of the single interstitial series are more minute and much 

 more widely separated; male with a distinct spine before each 

 anterior coxa, about as long as the basal thickness of the beak and 

 suberect and very acute, the abdomen feebly, indefinitely impressed 

 medio-basally. Length (cT 9 ) 3-0-3.35 mm.; width 1.4-1.7 mm. 

 Pennsylvania. Two specimens spiniger n. sp. 



Form not quite so stout, similar in coloration, lustre and sculpture; 

 beak (d^) almost similar but less arcuate, much longer than the 

 head and prothorax, with the antennae near three-fifths; prothorax 

 nearly similar but shorter, three-fourths wider than long, the smooth 

 median line similarly narrow and well defined; apical tubulation 

 similar; elytra similar but not so inflated, the grooves not quite so 

 coarse and the remote punctures along the bottom less evident; 

 intervals similar; legs much more conspicuously clothed with longer 

 and more bristling squamules, the abdomen similar, the prosternum 

 with a short and broadly angulate tubercle before each coxa; female 

 smaller than the male, with shorter beak, having the antennae at 

 the middle and the pronotal apex relatively broader than in the 

 male. Length (c?' 9 ) 2.8-3.25 mm.; width i. 25-1 .6 mm. Indiana. 



proximus n. sp. 



6 — Body smaller and more narrowly oval than in any of the preceding, 

 similarly black and shining; beak in the male evenly and distinctly 

 arcuate, rather thick, strongly sculptured and much longer than 

 the head and prothorax, the antennae rather beyond four-sevenths; 

 prothorax transverse, the sides less rapidly rounding anteriorly 

 than in either of the preceding, rounding before the middle, sub- 

 parallel basally, the sculpture closer, consisting of very large, oval, 

 subcontiguous punctures basally and close but coarse long rugae 

 elsewhere; smooth median line obliterated; elytra broadly oVoidal, 

 much wider than the prothorax and two and one-half times as long, 

 the sculpture as in proximus; male with a feeble medio-basal 

 abdominal impression, the prosternum without distinguishable 

 modification before the coxae; legs piceo-rufous. Length (cf) 2.85 



mm.; width 1.4 mm. New York. strigosicollis n. sp. 



— Pronotal punctures everywhere isolated and distinctly defined, even 

 at the sides and also beneath on the propleura; sparse setiform 

 squamules of the upper surface unusually distinct. Body very 

 stout, rounded-oval and convex, shining, black, the legs rufous; 

 beak in the male evenly, moderately arcuate, slightly tapering, a 

 little longer than the head and prothorax, the antennae somewhat 

 beyond four-sevenths; prothorax three-fifths wider than long, the 

 slightly converging and nearly straight sides broadly, evenly round- 

 ing in apical third to the short but strong tubulation, which is half 

 as wide as the base; median smooth line strongly defined and entire; 

 elytra barely visibly longer than wide, evenly elliptic, wider than 

 the prothorax and more than twice as long; grooves rather coarse, 

 intervals twice as wide as the grooves, the well separated uniserial 

 setae very distinct; male with a very short spiniform tubercle before 

 each anterior coxa. Length (cT) 3.1 mm.; width 1.5 mm. Iowa 

 (Iowa City), — Wickham puncticollis n. sp.
