sides of the pronotum and forming irregularly double lines on the 

 strial intervals, the scutellum and thoracic lobe densely albido- 

 squamose; under surface with dense white scales; beak in the male 

 feebly, evenly arcuate, thick, strongly sculptured and almost as 

 long as the head and prothorax, the antennae just behind three- 

 fifths; prothorax just visibly wider than long, the sides feebly 

 converging and subevenly, moderately arcuate, from base to the 

 unconstricted apex, which is half as wide as the base, becoming 

 gradually subparallel basally; smooth median line evident in part; 

 elytra nearly one-half longer than wide, parabolic, with obtusely 

 rounded apex, at the moderately swollen humeri distinctly wider 

 than the prothorax, about four- fifths longer; strice moderate; 

 intervals densely, coarsely and confusedly punctate and from two to 

 nearly three times as wide as the striae; male abdomen impressed 

 shallowly medio-basally though scarcely less squamose. Length 

 (cf ) 3.6 mm.; width 1.4 mm. Texas (New Braunfels), — Wickham.

 Punctures of the pronotum coarse, forming long longitudinal rugae 



throughout 17

The rugae evidently finer and closer 19 



18 — ^Form narrow, elongate-suboval, convex, black, the tibiae piceo- 

 rufous; squamules above distinct and white but rather sparse, a 

 little finer on the median parts of the pronotum, forming single and 

 double loose lines on the strial intervals, close and white beneath; 

 beak in the male rather thick, feebly arcuate, strongly sculptured 

 and fully as long as the head and prothorax, the antennae near three- 

 fifths; prothorax as long as wide, the sides moderately and evenly 

 arcuate from base to the unconstricted truncate apex, which is 

 much more than half as wide as the base; sculpture notably coarse, 

 • somewhat confused in part; elytra elongate-parabolic, with rather 

 obtusely rounded apex, only slightly wider than the prothorax and 

 fully four-fifths longer, fully three-fifths longer than wide; striae 

 moderate; intervals from two to nearly three times as wide as the 

 striae, distinctly but loosely, confusedly punctate; male abdomen 

 feebly impressed medio-basally. Length (cf ) 2.9 mm.; width i.o

Form much broader and more oblong-suboval, deep black throughout 

 the body and legs; squamules of the upper surface slender, glistening- 

 white, almost obsolete on the pronotum, except along the sides and 

 faintly along the feebly defined smooth median line; white scales 

 beneath conspicuous, though slightly separated, fine and less evident 

 on the propleura; beak (cf ) cylindric, coarsely sculptured, moder- 

 ately thick, evenly, feebly arcuate and as long as the head and 

 prothorax, the antennae near four-sevenths, or ( 9 ) a little longer, 

 with the antennae nearer the middle; prothorax nearly a fourth 

 wider than long, the sides feebly, subevenly arcuate and convergent 

 to the feeble apical constriction, the apex half as wide as the base; 

 rugee rather well defined; scutellum and thoracic lobe closely albido- 

 pubescent as usual; elytra three-sevenths longer than wide, at the
