Baring 497 



strongly and very densely punctate. Length (9) 3.8 mm.; width 

 1.7 mm. Missouri (St. Louis), — Schuster fusiformis n. sp. 



Prothorax shorter, with long anastomosing longitudinal rugae, the punc- 

 tures more or less isolated basally 3 



3 — Form notably stout, convex, shining, deep black, the legs piceous; 

 squamules of the upper surface very sparse but longer and more 

 distinct than in the preceding, especially on the elytra and in a 

 narrow sublateral thoracic line; under surface nearly similar; 

 beak (cf ) thick, strongly arcuate, densely sculptured and slightly 

 longer than the head and prothorax, or (9), longer, more slender 

 and less sculptured though not very smooth, strongly, evenly arcu- 

 ate and not quite half as long as the body; antennae near three- 

 fifths (cf ), or at the middle (9 ); prothorax one-half (cf ) to three- 

 fifths ( 9 ) wider than long, the converging and feebly arcuate sides 

 very rapidly rounded apically to the tubulate apex, especially in 

 the male, the apex barely half as wide as the base; smooth line 

 obliterated (cf), distinct (9); elytra slightly less elongate than in 

 fusiformis, otherwise nearly similar, though more obtuse at apex, 

 nearly three times as long as the prothorax in the female — this sex 

 smaller in size than the male — and with stronger interstitial punc- 

 tures. Length (d^ 9) 3.4-3.6 mm.; width 1.4-1.5 mm.; Missouri 

 (St. Louis). Taken by the writer. Two specimens. 



gravidula n. sp. 



Form less obese but nearly similar in coloration, lustre and vestiture, 

 the elytra differing in outline, being parallel to behind the middle 

 and then obliquely rounding to the apex; beak in the male a little 

 longer, still more evidently longer than the head and prothorax, 

 the latter similar, but with the apex rather more than half as wide 

 as the base; elytra one-half longer than wide, distinctly wider than 

 the prothorax and two and two-thirds times as long; striation 

 nearly similar; intervals having the punctures similar but more 

 inclined to uniserial arrangement on some of the intervals, the 

 punctures very much coarser than in fusiformis. Length (d^) 3.0 

 mm.; width 1.35 mm. Iowa ellipsoidea Csy. 



4 — Prothorax smaller, with more rapidly converging sides; size small. 

 Narrowly fusiform, convex, polished, black, the legs piceous; squam- 

 ules above very slender, almost invisible, more evident though 

 sparse near the sides of the prothorax and on the median line just 

 before the basal lobe; under surface as in the preceding species; 

 beak in the male unusually long and moderately thick, arcuate, 

 densely sculptured and much longer than the head and prothorax, 

 the antennae at four-sevenths; prothorax more than one-half wider 

 than long, the sides strongly converging from the base and straight, 

 moderately arcuate anteriorly, with the constriction very deep, the 

 tubulate apex more than half as wide as the base; punctures rather 

 coarse, in general well separated, partially subconfluent, the smooth 

 line entire and sharply defined; elytra ovulate, more than one-half 

 longer than wide, nearly a fourth wider than the prothorax and 

 between two and three times as long; interstitial punctures not very
