tliiiii twice as long as wide, those of the sides and siitnral interval 

 paler and contrasting strongly with the rest of the disk, wliich varies 

 in color from ochreo-cinereous to greenish or cupreons iniscix. 



S. siH»i«lns sp. nov. — Slightly more robust, but rather less convex than 

 elegans. Black, legs and anteunje bright rufous; vestiture consisting of broad 

 densely placed scales, whi(!h are nearly white on the sutural interval and at the 

 sides of the elytra, elsewhere ashy white, with faint greenish or pearly lustre; 

 elytral setaj visible only on the declivity, where they are short, subrecumbent 

 and inconspicuous. First funicular joint equal to the second and third united, 

 fourth distinctly longer than the third, fifth shortest. Thorax fully one-half 

 wider than long, widest at middle, sides evenly arcuate. Elytra widest at apical 

 third, posthutneral sinuatiou feeble. Front and middle tibia' strongly deei>ly 

 arcuate within in apical half, the inner margin almost angulate above the sinus; 

 outer margin more broadly arcuate toward the apex. Length 6.5 mm. 



Described from a single female taken by myself at Lake Tahoe, 

 California. 



S. niiscix sp. nov. — Black, antennae rufous, legs blackish in the male, 

 rufous in the female; vestiture dense, sides and sutural interspace of the elytra 

 cinereous, elsewhere with a decided ochreous or greenish tint ; scales somewhat 

 variable, but as rule quite twice as long as wide and rather coarsely strigose. 

 Autennte and legs nearly as inalbidus. Abdominal setce unusually numerous 

 and bristling in the male, less so in the female. Length 4.6-6.8 mm. 



The type series sent me by Mr. Ricksecker is from the vicinty of 

 Sacramento, California, and was I believe collected by Koebele. 

 With these I have placed specimens from Easton, Washington 

 (Koebele), and Helena, Montana (Hubbard and Schwarz), which 

 conform rather closely to the types, but are very variable in color, 

 some being brilliant green or cupreous. These strikingly resemble 

 elegans, but seem distinct and more nearly in accoi-d with miscix by 

 the more strongly emarginate, less parallel front tibiae ( S ), by the 

 more arcuate middle tibiae, the relatively longer fourth funicular 

 joint, the slightly more transverse thorax and the more hirsute 

 abdomen. 



Elegans seems to range entirely across the continent, there being 

 specimens from Montana and California in the material before me 

 which I am not able to separate. Californicus extends the entire 

 length of the Pacific district, and eastward to New Mexico, if .a 

 speciMin from the latter locality is properly referred.
