more separated, producing a strong dense bloom, 'the pygidium similar 

 in form, only very feebly convex and clothed nearly like the elytra; 

 hind tibiae much more dilated at apex than in the male, as usual in 

 the genus, and much longer than the tarsi. Length 21.8 mm.; 

 width 10.8 mm. One specimen. 



California (Shasta) and Oregon (Clackamas Co.). .longipalpis n. sp. 



Elytral vestiture squamiform 12 



12 Body moderate in size and stoutness, smaller and less cylindric than 

 the preceding, the vestiture very dense and cinereous- white; integu- 

 ments dark brown in color, the prothorax frequently rufescent; head 

 and concave clypeus densely clothed with coarse decumbent hair, 

 the long erect hairs dense and very conspicuous; last palpal joint 

 nearly one-half longer than the antennal club, which is unusually 

 small, the excavation entire, very deep and more or less open; pro- 

 thorax of the usual form, the sides generally coarsely crenulate 

 throughout, the basal angles obtuse, though only narrowly rounded, 

 and the side margins at base unusually reflexed; punctures strong, 

 irregularly close-set throughout, more so basally than apically; 

 vestiture with the usual medial and lateral condensations, the 

 decumbent hairs slender but evidently squamiform, sparse, the 

 erect hairs long and numerous; scutellar vestiture dense and elongate- 

 squamiform; elytra a third to two-fifths longer than wide, two-fifths 

 wider than the prothorax, not so abruptly rounded and obtuse at 

 apex as in the preceding, the coarse dense decumbent squamules 

 gradually pointed and four or five times as long as wide; pygidium 

 densely clothed with slightly narrower squamules, the abdomen still 

 less conspicuously clothed, though densely at the sides of each 

 segment; hind tarsi not quite as long as the tibiae. Length 18.0 

 20. o mm.; width 8.3-9.7 mm. Ten examples. 



Female larger and more elongate-cylindric than the male, cas- 

 taneous, the vestiture finer and less dense though very distinct; 

 head with slightly separated punctures and very fine, small, sparse 

 decumbent hairs, the erect hairs rather short and inconspicuous, 

 wanting on the clypeus, which is very short and concave; tumor of the 

 vertex large and very conspicuous; antennal club small, broadly oval, 

 the last palpal joint slender, two-thirds as long as the club, the 

 narrow excavation extending from basal to apical sixth; prothorax 

 relatively larger and broader than in the male, otherwise nearly 

 similar, except that the basal angles are rounded and the margin 

 basally not or scarcely reflexed; punctures rather coarse, irregularly 

 close-set, the long erect hairs numerous but not dense, the decumbent 

 hairs short, fine and sparse; scutellum with dense short squamuliform 

 vestiture; elytra somewhat as in the male but longer and about a 

 fourth wider than the prothorax, rugulose, sparsely, finely, irregularly 

 punctate, the prostrate hairs short, fine and only moderately close-set, 

 closer apically, along the suture and on the pygidium. Length 20.0 

 21. o mm.; width 9.5-10.0 mm. Four examples.
