Prothorax less coarsely to finely and usually very densely punctate, at 

 least in the male 21 



21 — Prothorax dilated anteriorly, so that it is wider before the middle 

 than at base. Form subparallel, convex, black, the legs rufescent; 

 squamules of the upper surface small and linear, whitish and evident 

 on the elytra; beak in the male almost evenly arcuate, feebly 

 tapering, dull in lustre and half as long as the body, the antennae 

 inserted at fully three-fifths, the first and second funicular joints 

 equal in length, the last transverse, the club paler, apparently with- 

 out basal denticle; prothorax not quite a third wider than long, the 

 sides strongly rounded before the middle, straight and feebly con- 

 verging thence to the base; apex feebly constricted, half as wide as 

 the base; punctures not coarse but strong, dense and distinctly 

 defined, the median smooth line traceable medially; elytra feebly 

 oblique and but slightly arcuate at the sides to the obtusely rounded 

 apex, a fourth longer than wide, at the rather prominent humeri 

 slightly wider than the prothorax, two-thirds longer; grooves 

 moderate though abrupt and deep, a third to fourth as wide as the 

 densely and not very coarsely punctato-rugose intervals; under 

 surface with dense white scales. Length (cf) 3-2 mm.; width 

 1.35 mm. Texas (Dallas), — Wickham parallelus n. sp. 



Prothorax of the usual form 22 



22 — Squamules of the elytra linear but white and distinct, arranged in 

 single lines, becoming double basally on some of the intervals; 

 basal thoracic lobe feeble. Body narrowly oval, strongly convex, 

 black throughout, not shining; squamules of the pronotum small, 

 sparse and inconspicuous; beak in the male evenly arcuate, not 

 very thick, dull, strongly sculptured and half as long as the body; 

 antennae inserted but slightly beyond the midd-le, the first two 

 funicular joints subequal in length, the club paler, narrower than 

 usual in the male and not distinctly dentate at base; prothorax 

 barely a fourth wider than long, the sides parallel in basal fourth, 

 thence feebly converging and nearly straight to apical fourth, then 

 gently rounding to the distinctly constricted apex, which is four- 

 sevenths as wide as the base; punctures moderate and very dense 

 throughout; smooth median line narrow and irregular, traceable 

 centrally; elytra almost a third longer than wide, narrowly parabolic 

 but with very feebly arcuate sides, at the feebly tumid humeri a 

 little wider than the prothorax; grooves deep, the intervals slightly 

 alternating, coarsely punctato-rugose and two to two and one-half 

 times as wide as the grooves; white scales dense on the under surface.

Squamules of the elytra linear, white and distinct though small and not 

 close-set, in single series or rather broadly confused on the alternately 

 very narrow and rather broad intervals. Body moderately stout, 

 subrhomboid-oval, convex, black throughout, the pronotal squam- 

 ules small, fine and inconspicuous, the dense scales of the under
