North American Species of TrogopJilmus, 379 



where it is scarcely more than one-seventh wider than long; sides 

 obtusely angulate and rounded, feebly convergent and feebly arcuate to 

 the apex, slightly more strongly convergent atid nearly straight toward 

 base; the latter feebly arcuate, scarcely three-fourths as wide as the 

 disk, very much narrower than the apex; the latter feebly arcuate; 

 basal angles rather more narrowly rounded than usual, apical obtuse, 

 slightly rounded; disk evenly convex, not impressed, finely, deeply, 

 and densely punctate, the median impunctate area very narrow, short, 

 and not at all well defined, not tumid. Elytra very nearly as long as 

 wide, nearly one-third wider and about one-fourth longer than the pro- 

 thorax, rather convex, very feebly impressed near the suture toward 

 base, moderately, rather deeply and densely punctate; punctures sepa- 

 rated by but slightly more than their own diameters. Abdomen slightly 

 narrower than the elytra, parallel; sides slightly arcuate; border mod- 

 erate; surface finely, feebly reticulate, minutely and rather densely 

 punctate. Legs slender. Length 1.9 mm.

The three species, facetus, scrupulus, and c07ifusus, are 

 mutually rather closely allied, and although at once distin- 

 guishable when compared, are not so easily differentiated by 

 description. It may be stated, however, that the prothorax of 

 facetus is distinctly transverse, excessively densely punctate, 

 alutaceous, and with a very narrow slightly tumid median im- 

 punctate area. In scrupulus the prothorax is not as transverse 

 as in facetus, and its surface is polished and more than twice as 

 sparsely punctate, the punctures feebler, and the median area 

 twice as wide and not at all tumid. In confusus the prothorax 

 is but just visibly wider than long, and is nearly as densely and 

 deeply punctate ?^sm facetus, hvit not alutaceous; the median 

 area is rather wider than in that species, not tumid, and not 

 very well denned; the eyes and elytra also are relatively smaller 

 than in either of the others. In scrupulus the elytra are more 

 sparsely punctate. 



61 T. scrupulus n. sp. — Moderately slender, rather convex, black; 

 legs piceous-black, tarsi paler; antennae black throughout; pubescence 

 extremely fine, short, rather sparse, and scarcely noticeable; integu- 

 ments shining. Head rather small, scarcely four-fifths as wide as the 

 prothorax, feebly convex, finely and strongly granulose and subaluta- 

 ceous, the punctures so nearly obsolete as to be not distinctly definable 

 amongst the granules; prominences small, but rather strong; antennae 

 short and robust, scarcely as long as the head and prothorax, strongly
