CERAMBYCID^E 213 



a strong double median cow-lick which does not attain base or apex; 

 elytra one-half wider than the prothorax and three times as long, 

 tapering in both sexes, everywhere minutely, closely punctate 

 and pubescent, the hairs rather long, dense, golden, generally 

 nearly transversely laid, with one or two more prominent irregular 

 lines of diverse lay. Length (cf 9 ) 11.5-12.5 mm.; width 3.1-3.6 



mm. California (probably the coast regions) aureatus n. sp. 



A Nearly similar to the preceding but a little stouter and with 

 silvery and not golden thoracic vestiture, which is however simi- 

 larly dense and thrown up in two similar medial longitudinal 

 cow-licks, differing distinctly in having the entire antennae, in- 

 cluding the basal joint, very pale yellowish-testaceous in color, 

 similar otherwise to the male antennae of aureatus, except that 

 the fourth joint is still a little shorter, being less than twice as 

 long as wide; eyes very slightly less prominent, similar other- 

 wise; prothorax similar in its sculpture and elongate form; 

 elytra similar in form, less alutaceous, the minute punctures less 

 dense or distinct, especially on the flanks, the marginal bead 

 blacker, pale basally; abdomen similar, the basal joint of the 

 hind tarsi distinctly longer. Length (cf ) 12.0 mm.; width 3.5 

 mm. California (locality unrecorded), Levette. 



gilvicornis n. subsp. 



Last dorsal ( 9 ) broader basally, more rapidly narrowing and with 

 slightly arcuate sides to the relatively more narrowly bilobed tip, 

 the median nick broader and shallower, angulate and forming a 

 right angle; body larger and much stouter, black, the elytra darker 

 red-brown, the abdomen ( 9 ) ferruginous, blackish at the sides 

 basally; legs brownish-testaceous, the antennae darker, brownish, 

 with the basal joint black; head nearly as in the preceding but with 

 smaller and less prominent eyes and scantier pubescence, the an- 

 tennae (9) scarcely more than one-half as long as the body; pro- 

 thorax larger and stouter, not quite so elongate and rather more 

 conical but otherwise similar, except that the pubescence is paler 

 yellowish-cinereous and much less dense, not concealing the sculp- 

 ture, which is a little coarser; elytra nearly as in the preceding but 

 broader and with shorter, less golden but more sericeous pubescence, 

 which is similarly irregular. Length (9 ) 12.7 mm.; width 3.9 mm. 



California (locality unknown) sericatus n. sp. 



Last dorsal (9) much broader, parabolic in form, the relatively much 

 narrowed apex bilobed, the nick angular and nearly as in sericatus, 

 the body nearly similar in form, coloration and sculpture but still 

 stouter; head similar but with still shorter and less conspicuous 

 pubescence, the antennae similar; prothorax shorter, stout, only 

 very little longer than wide, narrower at apex than at base, moder- 

 ately biconstricted, the obtuse and very moderate tubercles rather 

 more anterior, the punctures finer and denser, the pubescence short, 

 still more cinereous and not concealing the surface; elytra as in 

 sericatus but broader, the grayish pubescence still shorter and the 

 irregular lines much less evident. Length (9) 13-5 mm.; width 

 4.25 mm. Utah subpinguis n. sp.
