North American Species of TrogopJilostis. 355 



prominent than the eyes; antennae rather short and robust, gradually 

 and rather strongly clavate, as long as the head and prothorax; second 

 joint nearly as long as the next two together, but very slightly more 

 robust, twice as long as wide, third much longer than the fourth, the 

 latter about as long as wide, tenth very slightly wider than long. 

 Prothorax widest at anterior third, where the sides are broadly rounded 

 and coarctate to the apex, slightly more strongly convergent and very 

 feebly arcuate to the base, w^hich is feebly arcuate, nearly three-fourths 

 as wide as the disk, and much narrower than the apex; the latter trans- 

 'versely truncate; apical angles obtuse, not rounded; disk about one- 

 third wider than long, feebly convex, very strongly, longitudinally bi- 

 impressed, the impressions distinctly subinterrupted, finely and not 

 very densely punctate, the punctures much larger, denser, and more 

 scabrous near the sides. Elytra slightly wider than long, one-third 

 wider and longer than the prothorax, rather strongly impressed near 

 the suture, rather coarsely punctate, the punctures separated by nearly 

 twice their own widths, and finer and sparser exteriorly and toward 

 apex. Abdomen about as wide as the elytra; sides parallel and de- 

 cidedly arcuate; border moderate; surface finely reticulate, minutely 

 and sparsely punctate. Length 2.4-2.8 mm.

The joints two to four of the antennae may be said to 

 decrease nearly uniformly, and very rapidly in length. The 

 pronotal impressions are very strong, which, together with the 

 coloration of the body, will readily serve to identify this species. 



31 T. congener n. sp. — Rather slender, black; legs and antennae 

 throughout piceous; pubescence dense, short, fine; integuments feebly 

 shining. Head scarcely three-fourths as wide as the prothorax, rather 

 convex, minutely and extremely densely punctate, subalutaceous; 

 prominences short, strong; antennae distinctly longer than the head and 

 prothorax, slender, very feebly incrassate; joints two to four uniformly 

 and moderately decreasing in length, the latter decidedly elongate, 

 tenth very slightly longer than wide; eyes rather small, slightly promi- 

 nent, the tempora two-thirds as long, very strongly arcuate through- 

 out and as prominent as the eyes, not angulate. Prothorax nearly one- 

 half wider than long, widest at anterior two-fifths, where the sides are 

 rather broadly rounded; thence rather feebly convergent and slightly 

 arcuate to the apex, and more strongly so and very feebly arcuate to 

 the base; the latter broadly arcuate, two-thirds as wide as the disk, 

 very much narrower than the apex; the latter truncate; apical angles 

 obtuse, feebly, sublaterally dentate; basal obtuse, rather broadly 

 rounded; disk feebly convex, finely, rather deeply and very densely
