334 MEMOIRS ON THE COLEOPTERA 



as wide as long, roundly angulate at the sides, which are thence 

 feebly converging basally, more strongly apically; punctures 

 relatively rather small, well separated, each with a slender hair-like 

 depressed scale, varying in degree of fineness, becoming dense and 

 white in the strongly impressed median line and sublateral oblique 

 vittae, the latter interrupted beyond the middle, also with the erect 

 hairs sparse and only moderately long, becoming very long an- 

 teriorly; scutellum densely squamose along the middle; elytra a 

 third longer than wide, fully two-fifths wider than the prothorax, 

 circularly rounded behind, feebly rugulose and with rather fine 

 and irregularly sparse punctures bearing the yellow hair-like 

 scales, five or six times as long as wide, the dense white lines and 

 suture as in crinita; pygidium large, slightly transverse, triangular, 

 nearly flat, strongly reflexed at tip, very densely and evenly clothed 

 throughout with small whitish scales and fine short hairs; middle 

 tarsi scarcely more than four-fifths as long as the tibiae. Length 

 28.0 mm.; width 13.0 mm. A single specimen labeled "Texas" but 

 certainly in error and probably from Washington State. 



nigra n. subsp. 



B Male still larger in size, pale ferruginous in color throughout the 

 body, legs and antennae, the elytra piceous-black, the abdomen 

 black, paler at apex; pygidium obscure ferruginous; decumbent 

 scale-like hairs pale yellow, the erect hairs pale yellow-brown, the 

 dense lines of scales white; head somewhat as in the preceding, 

 except that the clypeus is notably broader, with the sides more 

 strongly converging from the obtusely rounded angles to the base; 

 vertex blackish; antennal club large, three times as long as the 

 stem; palpi as in nigra but paler in color; prothorax in outline nearly 

 as in the preceding, the sides' more nearly parallel in less than 

 basal half, strongly converging before the obtuse angulation, pale 

 rufous in color, with slightly coarser but shallow, irregularly rather 

 well separated punctures, the vittae and decumbent scale-like 

 hairs nearly similar, but the erect hairs are everywhere long, 

 abundant and very conspicuously shaggy, much more abundant 

 and longer, except apically, than in nigra; scutellum ferruginous, 

 densely squamose along the middle and with a few scales sparsely 

 scattered laterally; elytra large, two-fifths longer than wide and 

 two-fifths wider than the prothorax, rounding posteriorly from 

 slightly behind the middle, the dense white suture and vittae as in 

 nigra, the surface rather smoother, the small punctures more 

 numerous, the scale-like hairs five or six times as long as wide, 

 similarly very gradually and finely attenuate; pygidium in form 

 and vestiture nearly as in nigra; middle tarsi slightly longer, 

 almost as long as the tibiae. Length 32.0 mm.; width 14.0 mm. 

 A single example, without indication of locality but probably from 



Oregon mystica n. subsp. 



Antennal club notably small, only slightly longer than the head and not 

 quite twice as long as the stem, more nearly as in the opposita fuscida 

 series; body of smaller size than in crinita and allied forms; coloration 

 of the integuments and nature and coloration of the vestiture through-
