intervals each with a single series of long stiff erect hut rather fine 

 setae ; on the under surface the scales are whitish and very dense 

 throughout, intermixed with long setae on the abdomen. Beak in 

 the male short, thick, densely hispido-squamulose, nude and pol- 

 ished near the apex, subequal in length to the prothorax, the an- 

 tennae inserted near apical third. Prothorax nearly one-half wider 

 than long, the sides strongly evenly arcuate, convergent and 

 strongly constricted near the apex, the latter about one-half as 

 wide as the base. Elytra one-fourth wider than the prothorax 

 and very nearly three times as long, broadly angulato-emarginate 

 at base. Posterior femora obsoletely dentate. Length 2.9 mm. ; 

 width 1.25 mm. 



Texas. Readily known by its complex vestiture, transverse 

 prothorax, and fine long and semi-erect setae. The fifth ventral 

 segment is deeply and rather widely impressed or excavated in the 

 male. 



7 T. aratus Say.— Cure, p. 26 ; Ed. Lee. I, p. 294. 



Oblong-elongate, convex, black, the legs, antennae and tip of beak 

 rufescent; body densely clothed throughout with scales of various 

 forms and colors ; those of the beak robust and hair-like, usually 

 more or less bristling near the point of antennal insertion ; those of 

 the pronotum slender, strongly strigose, converging obliquely back- 

 ward, fulvous, but whitish along the middle and laterally near the 

 base ; those of the elytra very large, broad, widely imbricated, 

 granulose and not at all strigose in structure, and of various shades 

 of gray and blackish, confusedly intermingled; intervals of the 

 elytra each with a single series of long coarse bristling recurved 

 setae. Beak scarcely longer than the prothorax, just visibly arcu- 

 ate, very feebly tapering from base to apex, slightly constricted at 

 the antennae, the apical portion nude and shining ; antennae with 

 the first funicular joint as long as the next two. Prothorax one- 

 half wider than long, the apex rather abruptly narrowed and con- 

 stricted, less than one-half as wide as the base. Elytra at base 

 one-fourth wider than the prothorax, two and two-thirds times as 

 long, three-fifths longer than wide, the sides subparallel and straight 

 in basal three-fifths, evenly, obtusely rounded behind. Posterior 

 femora rather slender, strongly, obtusely prominent beneath at 

 apical fourth, and with the usual subapical emargination. Length 

 3.3 mm. ; width 1.4 mm.
