edges; elytra a fourth longer than wide and a fourth wider than the 

 prothorax, the sides parallel and feebly arcuate; apex rapidly ob- 

 tusely rounded; surface with the punctured striae deeply impressed 

 internally but very feeble throughout externally, the second interval 

 without coarse punctures; pygidium pearly in lustre, minutely, 

 remotely punctate, slightly strigilate toward base, not very convex. 

 Male with the hind margin of the last ventral rather abruptly 

 deflexed along the shallow sinus. Length (cf) 20.5-21.7 mm.; 

 width 11.0-12.0 mm. Mexico (Durango) *subenodis n. sp. 



Last joint of the maxillary palpi (cf ) with a large chagrined area, which 

 is very shallowly impressed, or never deeply concave 4 



4 Male with the clypeal suture rectilinear and transverse, obsolescent 

 only medially, the clypeal apex with a small acute medial sinus in 

 the type; eyes less developed, separated by rather more than three 

 times their width. Body more elongate and cylindric, pale and some- 

 what brassy-green and rather shining above, the clypeus cupreus; 

 entire under surface, legs and pygidium dark testaceous, with 

 brilliant pale cupreous lustre, the hind coxae more silvery, the meta- 

 sternum bluish only antero-medially ; head barely two-fifths as wide 

 as the prothorax, the clypeus strongly, irregularly and closely 

 punctate, twice as wide as long, parabolic, with the contour slightly 

 reflexed, more strongly at apex; prothorax scarcely three-fifths wider 

 than long, the sides evenly and moderately converging and broadly 

 arcuate from base to apex, the short apical angles very blunt, the 

 basal rounded; basal lobe distinct; punctures minute and remote, 

 more distinct and closer near the sides; scutellum much wider than 

 Jong, ogival, scabrous in a line paralleling the edges, elsewhere finely, 

 sparsely punctate; elytra barely wider than the prothorax, nearly a 

 third longer than wide, parallel, with feebly arcuate sides, rapidly 

 very obtusely rounded at apex, the impressed, distinctly and closely 

 punctate striae becoming very shallow laterad; second interval with 

 very few moderate punctures in single line; pygidium very shining 

 but somewhat pearly, sparsely and transversely scratched basally, 

 sparsely punctate apically, the median line feebly tumescent; sixth 

 ventral abruptly deflexed along the shallow sinus. Length (c? 1 ) 

 20.7 mm.; width n.o mm. Arizona (Cochise Co.).angusta n. sp. 



Male with the clypeal suture broadly arcuate, obsolete except laterally 

 but readily traceable by the sculpture, the apex obtusely rounded 

 and subtruncate; eyes larger and more prominent, separated by two 

 and one-half times their width. Body less elongate though rather 

 more so than in lecontei, colored as in the preceding but deeper and 

 purer green above and except that the entire metasternum is blue, 

 the hind coxae more shining, greenish; clypeus shorter, more trape- 

 zoidal, almost similarly punctate; prothorax nearly similar but 

 fully three-fourths wider than long and with the feebly arcuate sides 

 more converging from base to apex, all the angles better defined and 

 not more than roundly blunt at their apices, the sculpture similar; 

 scutellum much less transverse and more evenly punctate near the 

 edges; elytra similar in outline but shorter, not more than a fourth 

 longer than wide, the striae internally rather deeply impressed and
