here described, and especially rufipes, which is more southern in 

 habitat. It may be easily distinguished from those to which it is 

 mure closely allied by its polished surface — pruinose when living, — 

 the rather coarser and more distinct punctures of the intervals, 

 and by the form and size of the wings which consist of a slender 

 subopaque cellulo-membranous fillet, without noticeable venation, 

 slightly wider in apical half, about four-fifths as long as the pro- 

 thorax and less than one-third as long as the elytra. The male is 

 decidedly smaller and, especially, more slender than the female. 



Pulverulent us is distinctly smaller than rufipes and as these 

 species are both abundant, the differences maj^ be rendered very 

 obvious if the large series possessed by almost every cabinet of note 

 be properly separated. 



28 It. parallelUS n. sp. — Elongate-oval, subparallel, strongly convex, 

 rather strongly shining, black ; legs piceo-rufous ; pubescence fine, moderate 

 in length, sparse, dark piceo-t'ulvous and very inconspicuous. Head moder- 

 ately transverse, feebly convex, densely and deeply punctate ; upper lobe of 

 eyes small ; antennae rather robust, the last three joints rather abruptly but 

 slightly wider, third joint much shorter than the next two together. Prothorax 

 but slightly more than one-half wider than long, very feebly narrowed from 

 base to apex, the sides evenly and rather strongly arcuate ; basal sinuations 

 moderate ; basal angles right, not in the least rounded ; disk evenly convex, 

 very densely but not very confiuently punctate toward the sides, much more 

 sparsely so toward the middle especially near the base ; punctures moderate 

 in size. Scutellum ogival, rather finely and densely punctate, with the usual 

 impunctate polished margin. Elytra nearly three times as long as the protho- 

 rax, rather shorter in the male, subequal in width throughout to the latter, 

 narrowly, parabolically rounded at apex ; disk with rows of very fine punc- 

 tures, the stria? extremely feebly impressed, more visibly so toward the suture 

 but scarcely toward the sides, the punctures separated by from two to three 

 times their own diameters ; intervals fiat, finely and very sparsely punctured. 

 Abdomen finely, sparsely punctate, with short sparse inconspicuous pubescence; 

 surface generally more or less longitudinally rugulose. Legs moderate. 



Male. — Anterior tarsi very strongly dilated, the second joint much longer 

 than the third ; intermediate rather strongly dilated but much less so than 

 the anterior ; abdomen broadly, moderately impressed in the middle toward 

 base, the fifth segment with a small transversely-oval and rather strongly 

 impressed apical fovea. 



Length 5.0-5.5 mm. ; width 2.0-2 2 mm.

This species is closely allied to pulverulenlus, but differs in 

 several points to such a degree that I can see no other correct 

 course to pursue than to separate it. The form is rather narrower
