352 MEMOIRS ON THE COLEOPTERA 



in the sublateral condensations and along the very dense median 

 line; erect hairs wholly wanting; scutellum almost glabrous, narrowly 

 and densely squamulose along the middle but not to the apex; elytra 

 broader than in variolosa, two-fifths longer than wide, a fourth wider 

 than the prothorax, more rugose than in the preceding, the decumbent 

 short hairs white throughout, dense and evidently squamiform along 

 the suture and in the scattered irregular clusters, in which, similarly, 

 a vague lineal arrangement can be seen occasionally, very sparse but 

 coarse elsewhere; pygidium and abdomen nearly similar; middle 

 tarsi slightly shorter than the tibiae. Length 25.0-25.5 mm.; 

 width ii. 5-12. 3 mm. Kentucky. Three male examples.

32 Body of very small size and rather slender, moderately convex, sub- 

 cylindric form, rather shining, pale castaneous in color, the abdomen 

 blackish but paler apically; vestiture nearly as in the preceding 

 species, white throughout; vertex sparsely clothed with moderately 

 long subdecumbent, and but little longer erect, hairs, those near the 

 eyes feebly squamiform; clypeus less than twice as wide as long, 

 moderately concave, broadly sinuate at apex, with rounded angles 

 and nearly straight subparallel sides, very sparsely clothed with 

 stout decumbent hairs, smaller and denser apically, except toward 

 the sides, antennal club slender, only feebly reflexed distally, a 

 little more than twice as long as the stem; last palpal joint long and 

 slender, with an elongate flat area on the outer side; prothorax short, 

 more than twice as wide as long, the sides very obtusely and moder- 

 ately prominent medially; surface feebly rugulose, subevenly, not very 

 sparsely and moderately punctate, rather coarsely anteriorly, the 

 decumbent vestiture in the form of elongate lanceolate scales, with 

 a few minute hairs intermingled, dense along the median line and 

 more broadly, less densely aggregated in the usual sublateral vittae, 

 which are very irregular; scutellum squamulose throughout; elytra 

 nearly one-half longer than wide, only slightly wider than the pro- 

 thorax, rapidly rounding behind to the very obtuse apex, the suture 

 with slightly elevated margins but not in the least more densely 

 squamose, the irregular patches of dense white lanceolate scales 

 sometimes having a faintly lineate arrangement; surface rugose, the 

 punctures coarsely impressed; pygidium nearly as in variolosa; 

 middle tarsi not as long as the tibiae. Length 18.5-19.0 mm.; width 

 7.7-8.0 mm. Three examples. 



Female slightly stouter and more inflated posteriorly than the male, 

 with still somewhat shorter prothorax but otherwise almost as in 

 the male, except the head, which is shorter and relatively much 

 broader, the clypeus differing remarkably, being more than twice as 

 wide as long and regularly trapezoidal in form, the arcuate apex 

 scarcely more than three-fourths as wide as the base, the sides straight, 

 the angles moderately rounded; vertex much more coarsely and 

 densely punctate than in the male; last palpal joint much smaller, 

 very slender, with the outer flattened area much reduced; antennal 

 club small, scarcely more than half as long as the stem; pygidium less 

 evenly clothed and more densely, except toward the sides; tibiae, as
