not at all oblique or linear, the inner short and striiform; elytra 

 rather narrower, one-half longer than wide, scarcely visibly wider 

 than the prothorax, less convex, the subapical sinus small and rather 

 abruptly formed, much less broad and shallow than in formalis; 

 striation similar, the alternate intervals rather more notably con- 

 vex; apex more ogivally lobiform; scutellum smaller. Length (cf 9 ) 

 7.6-8.2 mm.; width 3.5-3.7 mm. New Mexico (Jemez Springs, 

 Sta. Fe and Fort Wingate) and Colorado (Boulder Co.).farcta Lee. 



Form nearly as in farcta but much smaller and distinctly narrower, 

 bright brassy-bronze in lustre; under surface with polished greenish 

 lustre; legs rufo-piceous, the femora black; elytra alutaceous in the 

 female, though micro-reticulate in both sexes; head slightly more 

 than half as wide as the prothorax, with moderately convex eyes 

 and well developed, somewhat irregular strioles; antennae rather 

 stout, black, with rufous basal joint, the medial joints on the com- 

 pressed side one-half (cf ) to a third ( 9 ) longer than wide; prothorax 

 short, very nearly twice as wide as long; apex deeply sinuate, with 

 prominent and only narrowly blunt angles, much narrower than the 

 base; sides finely reflexed, subevenly and feebly arcuate, scarcely 

 parallel basally; inner subbasal striole fine, short and subobsolete, 

 the outer small, fine, oblique and barely evident; transverse impres- 

 sions distinct; elytra nearly one-half longer than wide, at the middle 

 slightly wider than the prothorax, the sides arcuate, gradually ogival 

 in more than apical third; striae fine, impunctate, the scutellar mod- 

 erate, the lateral series narrowly interrupted medially; intervals 

 nearly flat, the marginal greenish; subapical sinus small but rather 

 deep. Length (cf 9 ) 7.2-7.7 mm.; width 3.2-3.3 mm. California 

 (Truckee). Two examples taken by the writer finitima n. sp. 



5 Antennae with the basal joint alone paler. Form oblong, rather de- 

 pressed, feebly shining, the elytra alutaceous, black, the under sur- 

 face shining and with pronounced greenish lustre; legs, coxaa and 

 trochanters black, sometimes partially with feeble piceous tinge; 

 head convex, the eyes rather large but feebly convex; strioles longer 

 than usual, deep and sometimes inflated internally; antennae not 

 very slender, short, black, with rufous basal joint, extending to 

 about basal third of the prothorax in the female; prothorax fully 

 three-fourths wider than long, the sides very gradually converging 

 and feebly arcuate from base to apex, the latter sinuate, with prom- 

 inent and scarcely at all blunt angles and much narrower than the 

 base; basal angles right, not rounded; surface nearly smooth, the 

 inner striole short, the outer diffused and feeble; elytra less than one- 

 half longer than wide, slightly wider than the prothorax, the sides 

 evenly arcuate, the sinus wide and rather deep, not abrupt; striae 

 very fine, impunctate, the scutellar long; lateral series narrowly or 

 only partially interrupted; intervals nearly flat, alternately just 

 visibly convex. Length ( 9 ) 8.3 mm. ; width 3.75-3.8 mm. Nevada 

 (Reno). Two examples taken by the writer subdepressa n. sp.
