Baring 429 



surface white; beak in the female slender, smooth, feebly arcuate, 

 slightly bent and thicker toward the head, half as long as the body; 

 antennae inserted just beyond the middle, slender; prothorax a 

 third wider than long, the sides very evenly arcuate from base to 

 apex, subparallel basally, converging apically, the apex not con- 

 stricted and distinctly less than half as wide as the base; punctures 

 moderately coarse, larger and less dense than in the preceding species, 

 distinctly separated throughout, with the smooth median line very 

 irregular but subentire; elytra in outline nearly as in defectus, at the 

 more prominent humeri slightly wider than the large prothorax and 

 only about three-fifths longer; grooves coarse; intervals as wide 

 as the grooves to twice as wide; punctures rather coarse and very 

 close but clearly defined. Length (9) 3-7 mm.; width 1.65 mm.

Squamules of the elytra confused on all the intervals 23 



23 — Prothorax unusually elongate, barely visibly shorter than wide.. .24 



Prothorax distinctly wider than long 25 



24 — Form narrowly subrhomboidal, moderately convex, black, the legs 

 not paler; squamules above very fine, whiter and distinct on the 

 elytra; beak in the male notably slender, arcuate, dull and coarsely 

 sculptured, slightly constricted near the base, half as long as the 

 body, the antennae piceo-rufous, inserted just beyond the middle, 

 the second funicular joint distinctly shorter and narrower than the 

 first, the last transversely cuneiform, the club large, the tooth very 

 short, feeble and obtuse; prothorax a fifth or sixth wider than long, 

 the sides feebly converging and nearly straight, gradually rounding 

 in apical third; apex feebly constricted and half as wide as the base, 

 punctures small, dense; smooth median line only vestigial centrally; 

 elytra with rather prominent humeral swelling, slightly wider and 

 three-fourths longer than the prothorax, a third longer than wide, 

 the sides feebly oblique and slightly arcuate to the relatively some- 

 what broadly obtuse apex; grooves moderate; intervals equal, twice 

 as wide as the grooves, the punctures rather coarse and very close 

 but clearly outlined; large dense scales of the under surface almost 

 white. Length (cf) 3-2 mm.; width 1.28 mm. Kentucky. Lev-

Form less narrow and more rhomboid, the sides of the elytra more 

 oblique and barely arcuate to the relatively narrower, though ob- 

 tusely rounded apex; coloration and vestiture nearly similar; beak 

 in the male thicker, not constricted near the base, dull and strongly 

 sculptured, more tapering, the sides flatter and more sulcate, simi- 

 larly arcuate but shorter, not half as long as the body, the antennae 

 . nearly similar, except that the tooth of the club is still smaller and 

 more feeble; prothorax larger, longer, barely visibly wider than 

 long, the sides and median line nearly similar; punctures much 

 coarser, dense; elytra broader basally, more triangular, less obtuse 

 at apex, a fourth longer than wide, at the prominent humeral swell- 

 ings distinctly wider than the prothorax, scarcely two-thirds longer; 

 grooves distinctly coarser than in regidaris, the intervals subequal, 

 much wider than in that species, though scarcely twice as wide as
