Interstitial punctures in even or uneven, at least approximately, single

4_Elytral punctures moderately strong and dense throughout. Form 

 rather broad but oblong-oval; beak shorter than the prothorax in 

 both sexes, feebly arcuate, more slender and smoother in the female 

 as usual; antennae inserted near three-fifths (cf ), or just behind the 

 middle ( 9 ) ; prothorax but slightly shorter than wide, the parallel 

 and feebly arcuate sides oblique in less than apical third, the apex 

 feebly constricted and fully half as wide as the base; punctures 

 deep and very close, the smooth median line distinct, entire; elytra 

 a little wider than the prothorax and very nearly twice as long, ob- 

 tusely rounded at apex; grooves moderately coarse, closely punctate, 

 not crenate; intervals from less to more than twice as wide as the 

 grooves; prosternal spines of the male long, slender and porrect. 

 Length (cf 9) 3.0-3.4 mm.; width 1.2-1.4 mm. Indiana, Missis- 

 sippi (Vicksburg) and Nebraska. Nine specimens. .. confusa Boh. 

 Elytral punctures coarser, similarly dense. Form more broadly oblong- 

 oval and larger in size, black throughout, subalutaceous, the fine 

 gray squamules rather sparse but everywhere evident, confused 

 throughout on the elytra; beak in the female very nearly as long as 

 the prothorax, very smooth and slender, feebly tapering, rather 

 strongly arcuate, the antennae slightly behind the middle; pro- 

 thorax larger than in confusa, very slightly wider than long, the 

 subparallel and feebly arcuate sides more rapidly and more trans- 

 versely rounded just behind the tubulate apex, which is fully half 

 as wide as the base; sculpture similar, except that the punctures are 

 a little coarser; elytra longer and with more converging arcuate 

 sides, three-fifths longer than wide, the apex similarly not very 

 obtuse and with somewhat individually distinct tips, distinctly 

 wider than the prothorax and almost twice as long; strise similar; 

 interstitial sculpture dense and much coarser and deeper. Length 

 (9) 3.65 mni.; width 1.45 mm. Kansas (locality unrecorded).

5 — Interstitial punctures nearly as strong as in confusa, the beak in the 

 female unusually arcuate. Body more ventricose, with relatively 

 wider elytra; beak in the female slightly longer than the prothorax, 

 slender, smooth and strongly arcuate, slightly tumid and more 

 punctulate at base, the antennae barely behind the middle; pro- 

 thorax shorter, a fifth wider than long, the parallel sides more arcu- 

 ate, more gradually oblique anteriorly, the feebly tubulate apex 

 rather more than half as wide as the base; elytra shorter, fully a 

 fifth wider than the prothorax and twice as long, obtusely sub- 

 parabolic, with moderate humeral callus; grooves moderately 

 coarse, not very deep; intervals twice as wide as the grooves, the
