North American Species of Trogoplilmus. 347 



by fully twice their own diameters, almost three times as wide at the 

 sides where they are very narrowly separated, but scarcely polygonally 

 crowded, impressions distinct, broad, even. Elytra nearly quadrate, 

 a little wider and nearly one-half longer than the prothorax, trans- 

 versely, rather strongly convex, very feebly impressed near the suture 

 toward base, rather coarsely and strongly punctate, the punctures sepa- 

 rated by slightly less than twice their own widths. Abdomen parallel, 

 slightly narrower than the elytra; sides feebly arcuate; border moderate; 

 surface very feebly reticulate, minutely and moderately densely punc- 

 tate. Legs slender. Length 2.4 mm.

Differs from spectatus, which it resembles in general char- 

 acters, in its more slender form, generally denser and more un- 

 even pronotal punctuation, and the more broadly rounded sides 

 of the prothorax. 



22 T. lepi<lu§ n. sp. — Rather slender, black; legs throughout pale 

 rufo-testaceous; antennee piceous-black, feebly rufous at base; pubes- 

 cence short, not very dense; integuments shining. Head moderate, 

 rather convex; antennal prominences short and strong; antennae dis- 

 tinctly longer than the head and prothorax, slender, very feebly in- 

 crassate; joints two to four uniformly and rather rapidly decreasing in 

 length, the latter one-third longer than wide; eyes large, moderately 

 prominent and more finely faceted than usual; tempora short, strongly 

 rounded, one-third as long. Prothorax one-third wider than long; 

 sides broadly rounded anteriorly, coarctate to the apex, rather strongly 

 convergent and distinctly, evenly arcuate to the base, the latter very 

 feebly arcuate, two-thirds as wide as the disk, much narrower than the 

 apex, the latter truncate; apical angles scarcely rounded; basal more 

 strongly so; disk widest at anterior two-fifths, rather convex, finely, 

 rather densely punctate, the punctures separated by about twice their 

 own widths, larger and denser at the sides; impressions distinct, slightly 

 subinterrupted in the middle. Elytra quadrate, distinctly wider and 

 two-fifths longer than the prothorax, very feebly impressed near the 

 suture toward base, rather coarsely, strongly, and unevenly punctate, 

 the punctures much finer and sparser laterally and toward apex, rather 

 dense toward suture and base. Abdomen parallel, very slightly narrower 

 than the elytra and slightly wider than the prothorax; sides feebly 

 arcuate; border moderate; surface finely subgranulose, feebly shining, 

 minutely and rather .sparsely punctate. Legs slender. Length 2.4 mm. 



Iowa (Cedar Eapids 1). Dr. E. Brendel. 



This very distinct species is to be easily identified by its 

 rounded converging sides of the prothorax, pale legs, piceous 

 antennae and rather more finely faceted eyes.
