half wider than long, subconical, the converging straight sides 

 becoming broadly arcuate anteriorly, the tubulate apex half as 

 wide as the base, the surface densely rugulose, the narrow smooth 

 line obliterated anteriorly; elytra two-fifths longer than wide, the 

 oblique sides evenly and rather strongly arcuate from the very 

 moderate humeral prominences to the somewhat acute apex, nearly 

 a third wider than the prothorax and between two and three times 

 as long; striae deep; intervals rather less than three times as wide 

 as the grooves, the punctures small, widely spaced in single series, 

 more close-set on the second and third, confused on the fifth basally; 

 squamules beneath denser on the last three abdominal segments. 

 Length (cf ) 2.3 mm.; width 1.15 mm. Missouri, — Schuster. 



densicollis n. sp. 

 Fine squamules above indistinct or very inconspicuous throughout.. .15 

 15 — Form somewhat as in the preceding but narrower, the sides of the 

 elytra subevenly oblique but less arcuate, with the apex similarly 

 narrowly subogival; color black, somewhat shining, the legs black; 

 beak in the female slender, nearly smooth distally, evenly and feebly 

 arcuate and distinctly longer than the head and prothorax, the an- 

 tennae at the middle; prothorax short, three-fifths wider than long, 

 trapezoidal, the strongly converging sides nearly straight to the 

 line strong apical constriction, the apex more than half as wide as 

 the base; surface with dense but relatively not very fine rugulosity, 

 the median smooth line obsolete; elytra three-sevenths longer than 

 wide, scarcely a fourth wider than the prothorax and between two 

 and three times as long; sides subparallel and nearly straight, oblique 

 and rounded in apical half, the humeral callus feebler than usual in 

 this section; striae moderate; intervals between three and four 

 times as wide as the striae, each with a single remotely spaced series 

 of very small punctures. Length (9) 1.7 mm.; width 0.78 mm.

Form stouter, the sides of the elytra less oblique, more feebly, subevenly 

 arcuate, the apex much more obtuse than in either of the two pre- 

 ceding; color black, rather shining, the pronotum and under surface 

 densely sculptured and dull; beak in the female slender, only just 

 visibly arcuate, nearly smooth distally, about as long as the head 

 and prothorax, the antennae barely perceptibly beyond the middle; 

 prothorax small, conical, with broadly arcuate, basally straighter 

 sides, scarcely one-half wider than long, the subtubulate apex 

 fully half as wide as the base; surface finely, very densely rugose, 

 the median smooth line wholly obliterated; elytra two-fifths longer 

 than wide, at the very prominent humeri fully two-fifths wider than 

 the prothorax, nearly three times as long; striae moderate; intervals 

 about three times as wide as the grooves, each with a single series of 

 small and well separated punctures. Length (9) 2.5 mm.; width 

 1.2 mm. Indiana. Levette collection parvicollis n. sp. 



The strigapunctus, of Hamilton, I find from a typical specimen 

 sent by the author, is none other than the true tuhulatus of Say.
