2 T. sordidus Lee— Proc. Am. Phil. Soc, XV, p. 217. 



Robust, oval, convex, rather densely and uniformly clothed 

 throughout with small slender scales, silvery gray to yellowish in 

 color, and generally a little more condensed along the elytral 

 suture ; erect setae completely wanting. Beak rather short, slender, 

 straight, cylindrical, feebly tapering and slightly bent near the apex, 

 barely as long as the prothorax, finely, densely punctate, squamu- 

 lose and more or less carinulate; antenna? inserted at apical third, 

 rather slender, the second funicular joint but slightly shorter than 

 the first, slender, outer joints barely perceptibly wider, the club 

 rather elongate, obliquely pointed at apex, rounded at base, almost 

 equally trisected by two straight sutures. Prothorax slightly wider 

 than long, the sides rapidly convergent from base to apex, broadly 

 and evenly arcuate, constricted behind the apex, the latter scarcely 

 more than one-third as wide as the base, the punctures circular, 

 deep and dense. Elytra parallel, broadly rounded behind, one-fourth 

 longer than wide, much wider than the prothorax and more than 

 twice as long. Posterior femora feebly toothed. Length 4.0-4.7 

 mm. ; width 2.1-2.4 mm. 



Iowa and Illinois. Our largest species, sufficiently common and 

 very readily recognizable by the characters given. The three speci- 

 mens before me are probably males ; in the female, the antenna? 

 are undoubtedly less apical. 



3 T. tectus Lee— Proc. Am. Phil. Soc, XV, p. 217. 



Oblong-oval, convex, black, the antennae rufescent; body covered 

 densely throughout with yellowish-white scales, whitish along the 

 suture and middle of the pronotum and also toward the sides of the 

 body ; scales rather wide but parallel and subelongate, strigose. 

 Beak evenly, moderately arcuate, subcylindrical, feebly tapering 

 only very near the apex, finely, densely punctured throughout, 

 densely squamulose but nude beyond the antennae, in the male much 

 shorter than the prothorax, with the antennae inserted near apical 

 third, in the female much longer, as long as the prothorax, with the 

 antennae inserted at the middle ; antennae slender, the basal joint of 

 the funicle as long as the next three, second slightly longer than the 

 third. Prothorax in the male two-fifths wider than long, with the 

 sides inflated before the middle and the apex less than one-half as 

 wide as the base, in the female longer, one-fourth wider than long, 

 with the sides parallel and nearly straight, the apex more than one-
