not depressed. Length 5.5 mm. New Mexico Horn (Bull. Bk. 

 VI, p. 52)] tenebrosus Lee. 



14 Body deep black, moderately shining, the under surface and femora 

 black, the tibiae and tarsi obscure rufous; head (d 71 ) evidently more 

 than half as wide as the prothorax, the eyes moderately large and 

 prominent; prothorax scarcely more than a third wider than long, 

 rounded on the sides and gradually narrowed anteriorly from behind 

 the middle, the apex feebly sinuate and four-fifths as wide as the 

 base, the apical angles but slightly rounded; surface distinctly 

 explanate near the hind angles and with fine punctures near the 

 base, the fovese subobsolete; elytra one-half longer than wide, the 

 side margins with a feeble prominence at basal fifth, the apical sinus 

 barely traceable, nearly obsolete; surface rather coarsely and deeply 

 striate, with moderate strial fovese and somewhat convex intervals. 

 Female with the head only scarcely visibly larger than in the male, 

 the prothorax distinctly shorter when compared with the elytra than 

 in that sex. Length (d 71 9 ) 6.3-6.8 mm.; width 2.5-2.7 mm. New 

 Jersey (Atlantic city), and Virginia, westward to Iowa (Keokuk).

parallelus Hald. 



Body and legs nearly similar throughout to the preceding, but somewhat 

 narrower, less convex and with a smaller head, the elytra not quite 

 one-half longer than wide, though twice as long as the prothorax, 

 the latter a little shorter than in parallelus, less explanate postero- 

 externally and with the anterior angles much more broadly rounded, 

 the hind angles generally less broadly rounded; elytra nearly similar, 

 but with a less visible protuberance at the sides near the base and with 

 the apical sinus more completely obsolete. Length (c? 9 ) 5.2-6.4 

 mm.; width 1.8-2.4 mm. Kansas, Texas and Colorado (Boulder). 



hesperus n. sp. 



The species named parallelus Hald., above, is the one usually 

 identified as Selenophorus parallelus of that author, but the original 

 description (Pr. Acad. Phila., I, 1843, p. 301) does not agree very 

 well; this is as follows: 



Lengthened oval, black, shining; antennae, palpi, tibiae and tarsi 

 rufous; femora darker or chestnut; head glabrous; posterior impressions 

 of the pronotum slight and minutely rugose; elytra slightly sinuate, 

 striate; striae alternately obsoletely punctured, a row of about 6 punctures 

 upon the inner edge of the 3d insterstice. 8 mill. long. Larger and 

 narrower in comparison than S. ellipticus, with the sides of the elytra 

 more nearly parallel and the abbreviated stria near the scutel more 

 distinct. 



No locality is given under the descripton, but, as the species is 

 listed in a catalogue of the Coleoptera of southeastern Pennsyl- 

 vania, preceding in the same paper, it is to be assumed that the 

 species is from that region. The length is materially greater than
