bescence very short and inconspicuous. Length ( $ ) 20.0 mm.; width 

 7.8 mm. Texas (near El Paso) obesus n. sp. 



A — Body nearly similar in general form but much narrower and with 

 less widely separated eyes; — alio wing for differences in sex prevailing 

 elsewhere, — and differing also most obviously in being wholly aeneous- 

 green, without trace of the strong cupreous color of obesus; elytra 

 similarly narrowly and deeply sinuate at the tips and strongly bispic- 

 ulose, the very short pubescence even more evidently arranged in 

 broad and moderately definite vittae. Length (c?) 17.5 mm.; width 

 6.5 mm. Texas (El Paso) aeneoviridis n. subsp. 



Form rather stout though evidently less so than in the preceding, cupreo- 

 seneous to deep coppery-red, shining, the pubescence very short and 

 sparse, not vittate on the elytra; head rather concave anteriorly, densely 

 punctate, more or less rugose posteriorly on the vertex; eyes much less 

 prominent, their outline continuing that of the head, becoming more 

 longitudinal posteriorly, pale brown with fine black margin in all the 

 numerous examples at hand; antennae nearly as in obesus but more 

 slender; prothorax nearly as in obesus but less narrowed anteriorly and 

 with the basal angles more strongly everted and acute, the scutellar 

 sinus a Httle deeper and more angular; elytra nearly similar through- 

 out though a Uttle more elongate, almost twice as long as wide ( c?) 

 or somewhat shorter ( 9 ) ; under surface nearly similar and with 

 numerous coarse perforate punctures along the middle of the proster- 

 num and densely throughout the width anteriorly. Length (c?) 

 12.5-16.5,(9) 13. 3-17. 5 mm.; width (d^) 4.0-6.2, ( 9) 4.6-6.8 mm. 

 Southeastern Arizona compactus n. sp. 



A — Body nearly as in compactus but larger and more oblong, bright 

 cupreous, the head slightly larger and with the eyes still more widely 

 separated; prothorax nearly similarly sculptured but more trans- 

 verse; elytra more evidently oblique at the sides in apical third, the 

 pubescence less uniformly distributed, being rather obviously in 

 single lines but without the broader vittae of obesus and ceneoviridis. 

 Length (9) 19.0 mm.; width 7.1 mm. Southeastern Arizona. 



solidus n. subsp. 



Form moderately robust, reddish or coppery-bronze, moderately shining; 

 prothorax with the sides moderately arcuate, the disk convex, coarsely 

 punctured, somewhat tuberculate at the sides from confluence of the 

 punctures but without distinct callosities; scutellum small, oval; elytra 

 densely and deeply punctate, the punctures near the apex less confused 

 and having a slight tendency to form striae ; body beneath more shining 

 than above, moderately densely punctured but smoother along the 

 median Une; prosternum very coarsely punctured in front, the process 

 smooth, with a row of coarse deep punctures so closely placed as to 

 resemble a groove. Length 15. 0-19.0 mm. North Carolina (near 

 Wilmington), — fide G. H. Horn carolinensis Horn 



15 — Body rather narrowly, subcylindrically convex, shining, cupreous, the 

 pubescence short but very evident, not vittate on the elytra; head for
