ClCINDELID^E AND CARABID^ 



sometimes traceable as a feeble vestige; apical spot vestigial; apical 

 margin of the labrum black in both sexes, broadly shaded with 

 piceous medially on the disk (9). Length (cf 9 ) 12.0-14.0 mm.; 



width 4.8-5.6 mm. California (Placer Co.) depressula Csy. 



A Similar but larger, broader and still flatter, darker and more obscure 

 green, the prothorax larger, wider than the head; humeral and 

 post-humeral spots both well developed, the apical spot also 

 large; punctures closer; under surface wholly deep violet-blue. 

 Length (d 71 ) 13.8 mm.; width 5.4 mm. California (locality 



unrecorded) scapularis Csy. 



Elytral humeri obtuse as usual in re panda and i2-guttata 7 



7 Under surface wholly polished green and blue; surface rather depressed, 

 the elytra more inflated in the female; color above blackish-brown, 

 never green, the maculation rather fine but variable as usual; all 

 the spots distinct; elytral granules small; labrum with a fine entire 

 black apical margin in both sexes, the female with a small quadrate 

 black anterior spot at the middle; prothorax rather large and trans- 

 verse, as wide as the head. Length (cf 9 ) 10.5-13.0 mm.; width 

 4.4-5.5 mm. Sierras from middle California and adjacent parts 



of Nevada to Washington State oregona Lee. 



Under surface shining metallic green or greenish-blue, the sides of the 

 sterna coppery; form stouter, the size larger, opaque, olive green to 

 coppery-brown above, the elytral markings generally larger than in 

 the preceding; labrum wholly pale in both sexes, with only an ex- 

 tremely fine apical margin black and without trace of a black 

 medial spot in the female; polished granules of the elytra larger, 

 denser and more conspicuous than in any other species. Length 

 (cf 9 ) 11.8-13.5 mm.; width 4.8-5.4 mm. Colorado, .audax n. sp. 

 8 Median band of the elytra having the usual form in the group, mode- 

 rately flexed posteriorly from the marked elbow on the medial line. .9 

 Median band very slender throughout, not broader at the transverse 

 part or posterior extremity as it is in all the preceding forms, ar- 

 cuately bent near the median line, the oblique posterior part longer 



than in any other species of the group 10 



9 Elytra barely one-half longer than wide, together gradually and 

 broadly rounded behind in about apical third, the edge broadly 

 rounded externally. Color pale coppery-bronze to obscure aeneous, 

 sometimes obscure greenish, always brighter and more coppery 

 toward the sides, the pale markings rather full, all the spots well 

 developed; labrum with a very fine black apical margin; prothorax 

 moderate, the sulci brighter coppery to blue; under surface bright 

 green to bluish-green, the sides of the sterna cupreous. Length 

 (cf 9) 11.0-12.5 mm.; width 4.5-5.4 mm. New Mexico and Colo- 

 rado guttif era Lee. 



A Similar to the preceding in size, sculpture and outline but brownish- 

 black, the elytra never more than feebly coppery at the sides; 

 under surface wholly shining metallic green or blue, the sterna 

 never coppery. Length (cf 9 ) 11.0-12.8 mm.; width 4.4-5.2 mm. 

 California (maritime regions north of San Francisco).
