Pseudomorpha behrensi

Description
P. Behrensi, n. sp.?Oblong parallel, moderately depressed, piceous black, shining. Head smooth, with but few distant punctures each bearing an erect yellow hair. Thorax moderately convex, nearly twice as broad as long, apex feebly emarginate, angles obtuse, sides strongly rounded, slightly converging to apex, hind angles broadly rounded, base truncate; sparsely muricately punc tured, each puncture with an erect hair, margin slightly reflexed and sparsely fimbriate. Elytra parallel, nearly twice longer than broad, feebly convex, sparsely muricately punctured, each puncture with a yellowish erect hair, margin sparsely fimbriate with yellow hairs. Body beneath ferruginous brown, abdomen punctured and pilose. Legs ferruginous, femora very robust. Length .38 inch; 9.5 mm. This species differs from Cronkhitei, Horn, in having the form more parallel and more convex. The thorax is much more convex and not as broad and the sides are more broadly rounded and converge less to the apex ; the lateral margin is more broadly reflexed and the im pression within, consequently deeper and extending faintly within the hind angles. In this species the disc of thorax has a median faintly elevated ridge which is scarcely at all evident in Cronkhitei. The elytra of Behrensi are parallel on the sides while, in Cronkhitei they con verge toward the apex, in the latter species the elytra are nearly smooth with scarcely any traces of punctures, in the latter species the muricate punctures are quite strong and though confusedly arranged at base are in strias beyond the middle. The femora of Behrensi are much more robust than those of the other species.

Distribution
For this interesting addition to the fauna of California, science is indebted to Mr. James Behrens of San Francisco, by whom a single specimen was collected and kindly placed at my disposal. I am not informed of the precise locality from which it was obtained. It must however belong to the fauna west of the Sierras.
