A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 247 



Head uniformly dark green, broadly, deeply depressed on vertex and occiput ; 

 front slightly convex; surface coarsely, rather densely, irregularly punctate, 

 more or less rugose behind clypeus, sparsely clothed with very short, erect, 

 inconspicuous hairs; clypeus deeply, angularly emarginate in front, arcuately 

 rounded on each side. Antenna brownish cupreous, greenish on basal segments, 

 distinctly narrowed to apex ; intermediate segments compact, nearly square, 

 broadly subtruncate at outer margins ; third segment slightly longer than follow- 

 ing two segments united. 



Pronotum twice as wide as long, subequal in width at base and apex, widest 

 along middle; sides parallel for nearly their entire length, slightly converging at 

 apical and posterior angles; anterior margin truncate; base broadly, arcuately 

 emarginate on each side, median lobe slightly produced and broadly rounded; 

 disk uniformly convex, without depressions or callosities ; surface coarsely, 

 densely, uniformly punctate, distinctly, transversely rugose, intervals densely 

 granulose. 



Elytra slightly wider than pronotum, nearly twice as long as wide ; sides 

 parallel from humeral angles to behind middle, then arcuately converging to tips, 

 which are separately narrowly rounded ;* lateral margins coarsely serrate ; basal 

 depressions broad and moderately deep ; humeral depressions obsolete ; disk 

 moderately convex, slightly uneven; surface glabrous, without foveae or costae,. 

 coarsely, densely, uniformly punctate, transversely rugose, intervals densely 

 granulose. 



Abdomen beneath coarsely, rather sparsely, uniformly punctate, sparsely clothed 

 toward sides with very short, recumbent, inconspicuous, white hairs, intervals 

 densely granulose, without lateral callosities ; last visible sternite shallowly.. 

 broadly emarginate at apex, with a strongly elevated, coarsely serrate, submar- 

 ginal ridge, which is transversely truncate in front of apex, lateral margins 

 slightly sinuate, but not serrate ; eighth tergite not visible. Prosternum coarsely, 

 densely punctate, coarsely, transversely rugose, with a few very short, inconspicu- 

 ous hairs, anterior margin rounded, with a rather broad, short, median lobe. 

 Anterior femur with a short, broad, triangular tooth, which is coarsely dentate 

 on outer margin. Anterior tibia strongly arcuate, unarmed ; middle and posterior 

 tibiae straight. 



Length 6 mm., width 2.25 mm. 



Redescribed from the type in the Fall Collection (in the Museum of 

 Comparative Zoology, Cambridge, Mass.). 



Male. — Differing from the female in having the last visible abdominal sternite 

 more deeply emarginate at apex. The genitalia are similar to those of bicolor. 

 The anterior tibia is unarmed in both sexes. 



Type locality.— -"Oak Creek Canyon, 6,000 feet, Ariz., July, F. EL 

 Snow." 



Host. — Unknown. 



Fall described the species from a single female, and the only other 

 specimen examined by the writer is a male collected June 30, 1939, at 

 Prescott, Ariz., by D. J. and J. N. Knull, and a male collected at Globe, 

 Ariz., by D. K. Duncan.
