Baring 503 



less than one-half wider than long, the converging sides straight, 

 rapidly and strongly rounding anteriorly, but for only a very short 

 distance, to the tubulate apex, which is half as wide as the base; 

 surface finely, densely rugulose; smooth line distinct only toward 

 base: elytra but little over a fourth longer than wide, the sides 

 feebly converging in basal, more rapidly oblique and rounded in 

 apical, half, a third wider than the prothorax and rather less than 

 two and one-half times as long; striae fine, about a fourth as wide 

 as the intervals, the single series composed of minute and widely 

 separated punctures. Length (cf) 1-8 mm., width 0.85 mm. 

 Pennsylvania. A single typical example subcalvus Lee. 



Body less minute, convex and very much stouter in form, the humeri 

 similarly prominent; fine darkish squamules above minute and 

 very inconspicuous, more evident and whiter beneath 13 



13 — Form subrhombic, very stout and convex, shining, black, the legs 

 black; beak in the female rather long, feebly arcuate, distinctly 

 sculptured and very much longer than the head and prothorax, the 

 antennae at about the middle; prothorax conical, scarcely one-half 

 wider than long, the strongly converging sides very feebly, subevenly 

 arcuate throughout, the constriction not deep, the subtubulate apex 

 half as wide as the base; surface finely, densely rugulose, the smooth 

 line narrow, distinct only toward base; elytra a fourth longer than 

 wide, a third wider than the prothorax and more than two and one- 

 half times as long, the sides behind the prominent humeri parallel 

 and straight, rounding and oblique in apical half to the narrowly 

 rounded apex; striae moderate; intervals three times as wide as the 

 striae, with single series of fine and distant punctures. Length (9 ) 

 2.15 mm.; width 1.15 mm. Missouri (locality unrecorded). 



nanulus n. sp. 



Form very broadly oval, convex, black and shining, the legs black; beak 

 moderately thick, evenly, very feebly arcuate, distinctly longer than 

 the head and prothorax and strongly sculptured; antennae at four- 

 sevenths; prothorax nearly as in the preceding but more transverse 

 and with more strongly converging sides, notably arcuate only for a 

 very short distance at the tubulate apex, which is more than half 

 as wide as the base, two-thirds wider than long, very densely rugu- 

 lose, the fine smooth line traceable only basally; elytra broader, 

 barely a fifth longer than wide, subelliptic, with narrowly rounded 

 apex, a fourth wider than the prothorax and two and one-half times 

 as long; striae moderate; intervals between three and four times as 

 wide as the grooves, the punctures fine and distant, forming rather 

 less regular single series than usual. Length (d^) 2.25 mm.; width 

 1.2 mm. Kentucky. One example brevipennis n. sp. 



l4^Fine and suberect, setiform squamules of the elytra forming even 

 single lines and very distinct. Body fusiform, narrowly rounded 

 behind, convex, moderately shining, black, the legs partially piceous; 

 squamules on the pronotum more evident in a small spot at the basal 

 lobe, inconspicuous beneath; beak in the male slender, sculptured, 

 evenly and feebly arcuate and evidently longer than the head and 

 prothorax, the antennae at four-sevenths; prothorax not quite one-
