next two combined. Length ( $ ) 19.5 mm. ; width 6.8 mm. Washing- 

 ton State (Tacoma) leviceps n. sp. 



Size much smaller, shining, almost pure vivid green above, the under sur- 

 face, except laterally, and the abdomen ceneo-cupreolate; head relatively 

 somewhat larger, strongly, confluently punctate, the eyes moderate, not 

 noticeably prominent; antenna? black, with the metallic lustre greatly 

 diminishing apically; prothorax nearly four- fifths wider than long, al- 

 most parallel, the sides but feebly arcuate though more rounding and 

 converging anteriorly, the apex less evidently narrower than the base; 

 surface strongly punctate, densely laterally, with four small rounded 

 impressions, one on each side of the broadly and feebly impressed 

 median line just before the middle, the others in the usual sublateral 

 position but feebler than in the preceding; elytra slightly more than 

 twice as long as wide, the sides more rectilinearly oblique apically, 

 five times as long as the prothorax and almost a third wider, sculptured 

 as in the preceding, immaculate; under surface similar, the fifth ventral 

 in the male rather narrowly truncate at tip, the truncature very faintly 

 bisinuate. Length (cJ*) 15.3 mm.; width 5.3 mm. California, — Cab. 

 Levette depressa n. sp. 



42 — Body beneath coarsely punctured; elytra cupreous at the sides. Form 

 elongate-oval, subdepressed; head moderately densely punctate, brilliant 

 green in color changing to cupreous ; prothorax broader than long, nar- 

 rower in front, the sides very feebly arcuate; surface moderately convex, 

 with rather coarse punctures, which are more densely placed at the sides, 

 brilliant cupreous in color ; elytra at base wider than the prothorax, oblong- 

 oval, the apex feebly attenuate, the tips feebly emarginate, with the sutural 

 angle acute and slightly prolonged; surface striate, the intervals equal, 

 moderately convex and sparsely punctate, the coloration diversified, 

 brilliant blue along the suture, shading to green, with the margin cu- 

 preous ; under surface very densely punctured at the sides of the metaster- 

 num and abdomen, brilliant cupreous in color with green reflection; 

 prosternum and first ventral not sulcate. Length 15.0 mm. Cali- 

 fornia (Owen's Valley) and Oregon connexa Horn 



Body beneath finely punctured, more closely and strongly laterally as usual; 

 elytra sometimes suffusedly cupreolate but never with distinct cupreous 

 side margins 43 



43 — Species of the Pacific coast regions 44 



Species of the far interior of the continent 45 



44 — Prothorax but slightly narrowed anteriorly, the sides almost parallel; 

 upper surface pure brilliant green, the under surface cupreolate as 

 usual. Body depressed, very shining; head very densely and conflu- 

 ently but almost evenly punctate, the eyes not prominent; prothorax 

 fully three-fourths wider than long, the sides nearly straight and par- 

 allel, gradually more rounding and converging anteriorly; surface 

 coarsely punctate, confluently so laterally, feebly impressed on the 

 median line, the sublateral rounded impression behind the middle
