from base to the faint apical constriction; apex less than half as 

 wide as the base; elytra ovoidal, the striae coarser and deeper than 

 in helvinus. Length {(^ 9) 2.25-2.85 mm.; width 0.9-1.3 mm. 

 Maryland and District of Columbia to Mississippi (Agricultural 

 College). Six examples alternatus Csy. 



Form more abbreviated than in alternatus, the size smaller; color simi- 

 larly obscure rufo-piceous; scales above pale yellowish, slender and 

 moderately close on the pronotum, a little more visible laterally, 

 the strial intervals almost uniformly but loosely clothed with 

 slender squamules, not forming more than two irregular lines on 

 each, but coarser and dense on the third behind the middle; beak 

 shorter and less arcuate, the antennae inserted slightly (cf), or 

 much (9), behind the middle; prothorax distinctly shorter and 

 more transverse, two-fifths to one-half wider than long, the sides 

 strongly, subevenly arcuate, gradually becoming parallel basally; 

 punctures dense; elytra shorter, broadly ovoidal, the striae deep but 

 only moderately coarse; intervals subequal and almost twice as 

 wide as the striae, the first much narrower as usual. Length (cf 9 ) 

 1.8-2.25 mm.; width 0.78-^1.0 mm. Illinois, — F. M. Webster. 



curtulatus n, sp. 



4 — Body small, rather narrowly suboval, the elytra inflated and the 

 prothorax narrow; color almost black; squamules of the upper 

 surface yellowish, slender and uniform on the pronotum, not more 

 distinct laterally and barely so along the median line, whiter and 

 coarser on the elytra, which are obscure rufous in color, almost 

 uniformly distributed but forming not more than two irregular 

 lines on each interval; beak in the female moderate in thickness and 

 curvature, slightly longer than the head and prothorax, the antennae 

 inserted far behind the middle; prothorax a fifth wider than long, 

 the sides moderately converging, nearly straight, becoming broadly, 

 feebly arcuate anteriorly; apex barely more than half as wide as 

 the base; punctures dense; elytra ovoidal, rather pointed at apex, 

 the individual apices narrowly rounded as usual in the genus; 

 striae deep, moderate; intervals subequal, twice as wide as the 

 striae, excepting the very narrow first interval. Length (9) i-8 

 mm.; width 0.7 mm. Indiana. Levette collection. 



angusticolUs n. sp 



5 — Pronotum densely but subevenly punctate 6 



Pronotum with the punctures more or less confluent, forming coarse 

 broken longitudinal rugae 9 



6 — Pale scales of the elytra dense through most of intervals two and 

 five, the pronotum with two broad and distinct vittae of more 

 fulvous and less conspicuous squamules. Body rhomboidal, nearly 

 black, the legs rufo-piceous; pale scales above yellowish and glisten- 

 ing; beak in the male much longer than the head and prothorax, 

 arcuate, the antennje inserted slightly beyond the middle and the 

 funicle longer than in the preceding section, the male prosternum 

 unarmed; prothorax nearly one-half wider than long, the sides sub- 

 evenly and strongly arcuate to the evident apical constriction, 

 becoming parallel basally; apex half as wide as the base; elytra
