arcuate, as long as the head and prothorax and strongly sculptured, 

 the antennae at four-sevenths; prothorax as long as wide, the sides 

 parallel and straight, broadly rounding before the middle to the 

 unconstricted apex; punctures deep and strong, moderately coarse, 

 separated by their own diameters; elytra narrowly oval, at the 

 moderate humeral swellings evidently wider than the prothorax, 

 about three-fourths longer; apex rather obtusely though circularly 

 rounded; strial grooves deep and sharply defined, the intervals each 

 M'ith a single series of well separated and moderate punctures, twice 

 as wide as the grooves or less. Length (9) 2.3 mm.; width 1.18

12 — Prothorax with the sides rapidly rounding in scarcely more than 

 apical fourth. Body narrowly suboval, black, somewhat shining, 

 the legs obscure rufous; squamules above narrow and whitish, 

 distinct, not dense, less evident on the median parts of the pronotum, 

 generally in a single line on the strial intervals, though irregularly 

 double on two or three; white scales dense beneath; beak in the 

 male thick, cylindric, evenly and moderately arcuate and fully as 

 long as the head and prothorax, deeply, not closely sculptured, the 

 antennae at four-sevenths; prothorax a fifth wider than long, the 

 sides very feebly arcuate, rounded at apex, which is more than half 

 as wide as the base; punctures moderate, not dense but irregular, 

 the smooth line subentire; scutellum quadrate and densely albido- 

 squamose; elytra nearly one-half longer than wide, three-fourths 

 longer than the prothorax and slightly wider, the sides moderately 

 oblique and subparabolicallj' rounded; striae moderate; intervals 

 flat, strongly punctured and of unequal widths; male with a but 

 little less squamose medio-basal impression. Length (c?') 3.3 mm.; 



width 1.3 mm. Iowa (Hamburg), — Soltau simulans n. sp. 



Prothorax with the sides gradually rounding and converging in fully 



apical half 13 



13 — Body elongate, subrhomboid-oval, rather convex and dullish black, 

 the legs obscure rufous; whitish squamules of the upper surface 

 nearly as in the preceding but more conspicuous, similarly arranged 

 on the pronotum and scutellum, dense and white below; beak (cf ) 

 feebly arcuate, dull and strongly sculptured, slightly thickened at 

 base, or (9 ) nearly similar but more slender, about as long as the 

 head and prothorax in both sexes, the antennae at three-fifths (cf ) 

 or four-sevenths (9 ); prothorax a fourth (9 ) to a sixth (cf ) wider 

 than long, the sides becoming parallel in about basal half; punctures 

 rather coarse and close-set; median smooth line narrow, entire; 

 elytra nearly one-half (cf) to two-fifths (9) longer than wide, 

 elongate-parabolic, the apex somewhat obtusely rounded, at the 

 rather prominent humeri distinctly wider than the prothorax, three- 

 fourths longer; striae moderate, one-half as wide as the intervals or 

 much more; interstitial punctures small, not dense; male with a
