male of similis than in the same sex of montanus, being scarcely 

 more than one half longer than wide and more obviously wider 

 than crest. In montanus the sexual disparity in the size of the 

 horn is very great. The truncature of the last ventral segment 

 ((^) is distinctly more strongly emarginate in similis than in mon- 

 tanus. 



Although agreeing in the dentate male front tibiae with cal- 

 caratus, both montanus and similis differ considerably from the 

 latter in general habitus, and resemble rather bifasciatus, which 

 of course is very distinct by its interrupted pale elytral fasciae 

 and the simple fore tibiae in the male. 



Notoxus intermedius n. sp. Moderately stout, testaceous ; elytral mark- 

 ings, consisting of a small basal subsutural spot on each, a median trans- 

 verse fascia and a small subapical one, black. Both the basal and sub- 

 apical marks are, however, either entirely wanting or but faintly indicated 

 in more than half the specimens seen. Decumbent pubescence not dense, 

 intermixed with semierect hairs of moderate length; integuments shining, 

 moderately closely finely punctate. Antennae scarcely or feebly incrassate 

 apically, the tenth joint scarcely one half longer than wide. Eyes a little 

 longer than the tempora. Prothoracic horn (c?) moderately stout, fully 

 one half longer than wide, not constricted at base, margin not dentellate 

 except basally, broadly evenly rounded apically; crest well developed, mar- 

 gin not dentellate. In the female the horn is wider and constricted basally. 

 Elytra twice as long as wide or very nearly so, feebly inflated post- 

 medially, sutural angles rounded, not distinctly produced in the male, a 

 little produced and with a slight external sinuation in the female. Be- 

 neath finely punctate and pubescent; legs moderate, the anterior tibiae 

 toothed at the middle of the inner margin in the male; last ventral not 

 impressed, the apex distinctly emarginato-truncate in the male, subacute 

 and narrowly rounded at apex in the female. 



Length 3.2-4 mm.; width 1.1-1.35 mm. 



Described from a series of thirteen specimens taken by Dr. 

 Fenyes at Bishop and Olancha, Inyo, Co., California. The type 

 is a male from Bishop. 



This species, in its fully marked form, is closely similar to cal- 

 caratus, which differs in its much longer and more numerous 

 elytral setae, stouter prothoracic horn with distinctly dentellate 

 side margins, sutural angles not produced in the female, and with 

 the last ventral in the male impressed and feebly truncate, but 

 not emarginate at apex. The sexual characters are nearly as in 

 montanus and similis, especially the later, but the size and gen- 

 eral appearance are nearly as in calcaratus.
