NORTH AMERICAN COLEOPTERA. 249 



P. Hainiltoili n. sxi.— Oblong oval, scarcely narrowed iu front, moderately 

 convex, above piceo-testaceous or pale brownish, head behind the suture piceous, 

 clypeus usually testaceous %, or broadly piceous at middle 9; thorax with an 

 indefinite, semi-circular space piceous, a small dark spot on each umbone. Thorax 

 not very closely punctate, smoother near the sides, the usual arcuate and trans- 

 verse series of coarser punctures extremely indistinct. Elytra a little more 

 coarsely punctured than the thorax, toward the apex more sparsely and less 

 deeply, the discal rows of coarser punctures scarcely discernible. Body beneath 

 and femora opaque black, the trochanters, tibite and tarsi testaceous. Length 

 .16— .22 inch. ; 4—5.5 mm. PI. iii, fig. 9. 



The mesosternal lamina is moderately prominent, the lower edge horizontal, 

 the anterior edge vertical and sinuous, the angle distinctly mucronate. 



The anterior pair of claws of the male are dissimilar, the front claw having a 

 long lobe-like, obtuse tooth at base, which is slightly everted, the hinder claw 

 rectangularly toothed. The middle pair of claws are similar, and each has a 

 broad rectangular tooth. The posterior claws are smaller, slightly irregular in 

 shape, each has an acute tooth at base smaller than in the middle claws. The 

 claws of the female are alike on all the feet, and are merely broadened at base. 



This species might readily be mistaken for a larger reftexipennu 

 when recently captured specimens are compared, a resemblance 

 which is increased by a slight explanation of the sides of the elytra 

 near the apex. It will be observed, however, that in reflexipennis 

 the head is always entirely pale, as also the thorax, while in the 

 present species the posterior portion of head, at least, is piceous. 

 The darker disc of the thorax is present, with very rare exception, 

 wdiile in reflexipennis it is never so. 



The characters observed in the male claws will certainly separate 

 the two species, while the more general characters above given must 

 be relied on for the other sex. 



Occurs in Canada (Pettit), Massachusetts (Blanchard), the coast 

 of New Jersey (Hamilton), northern California and Oregon. 



P. (liffiiSllS Lee. — Oblong oval, moderately convex, pale piceo-testaceous 

 above, head behind the frontal suture piceous or black, clypeus piceous at middle. 

 Thorax moderately closely punctate, the punctures coarser toward the side, the 

 arcuate and transverse rows of coarser punctures well marked. Elytra a little 

 more coarsely punctured than the thorax, the punctures somewhat coarser, but 

 less dense toward the apex, the usual rows of coarser punctures i-ather indis- 

 tinctly impressed. Body beneath and femora piceous opaque, tibiae and tarsi 

 pale. Length .18— .24 inch. ; 4.5—6 mm. PI. iii, fig. 11. 



The mesosternal crest is prominent, the lower edge oblique, the anterior edge 

 oblique, the angle feebly mucronate. 



The claws of the anterior male feet are dissimilar, the front claw having a 

 large lobe-like tooth at base, which is not in the same plane as the tip of the 

 tooth, so that when viewed directly from above the claw seems double, the pos- 

 terior claw is less curved and has a rectangular tooth at base. The claws of the
