nearly smooth space; surface coarsely, deeply, conflueutly punctate between 

 smooth spaces. 



Elytra distinctly wider than pronotum, five-sixths longer than wide ; sides 

 parallel from humeral angles to just behind middle, then obliquely converging 

 to tips, which are separately broadly rounded ; lateral margins coarsely serrate ; 

 basal depressions broad, very deep ; humeral depressions broad, moderately 

 deep ; surface glabrous, uneven, intervals between costae and smooth spaces 

 coarsely, deeply, confluently punctate. Each elytron with four more or less dis- 

 tinct longitudinal costae ; first straight, extending from apex to base, very narrow 

 on apical half, broadly dilated on basal half; second narrow near apex, in- 

 terrupted at apical third, then expanded into a wide, smooth space, becoming 

 narrower and irregular on basal third ; third narrow, broadly interrupted behind 

 middle, expanded and joined to second near middle and at basal third; fourth 

 barely indicated, extending along lateral margin from humerus to apex. 



Abdomen beneath finely, deeply, rather densely, irregularly fossulate-punctate, 

 sparsely clothed with very short, recumbent, white hairs, with more or less dis- 

 tinct lateral callosities, intervals indistinctly granulose ; last visible sternite deeply, 

 broadly, arcuately emarginate at apex, with a rather distinct, serrate, submarginal 

 ridge, lateral margins coarsely serrate ; eighth tergite subtruncate at apex, coarsely, 

 deeply, confluently punctate, but not longitudinally carinate. Prosternum coarsely, 

 densely, transversely rugose, densely clothed with long, semierect, white hairs, 

 with a smooth, longitudinal, median line ; anterior margin strongly, arcuately 

 rounded at middle, with a broad, short, median lobe. Anterior femur with a large, 

 acutely angular tooth, which is dentate on outer margin. Anterior and middle 

 tibiae slightly arcuate, the former with a long, sinuate dilation at apex, posterior 

 tibia straight. 



Length 12 mm., width 5.5 mm. 



Redescribed from the male type, No. 2700, in the Museum of Com- 

 parative Zoology, Cambridge, Mass. 



Female. — Differing from the male in having front of head uniformly brownish 

 cupreous, more sparsely punctured and more sparsely pubescent, antenna piceous, 

 with a vague greenish reflection, last visible sternite slightly longer, and broadly 

 subtruncate at apex, the eighth tergite broadly rounded at apex and more deeply 

 punctate, prosternum coarsely, sparsely punctate, and very sparsely pubescent, 

 anterior tibia unarmed at the apex, and middle tibia straight. 



Type locality. — Santa Fe, 1ST. Mex. (Type simply labeled with a 

 dark-green disk.) 



DISTEIBtTTION 



From material examined: 



Arizona: No definite locality (Horn collection). 



New Mexico: Sante Fe, type series (Fendler). Mt. Capitan, August 29 (Bryant). 

 Cloudcroft, September 5 (S. Shimek). 



Also recorded in the literature from : 



Arizona: Carr's Peak, Huachuca Mountains (Chamberlin 1926). 



California: Pinon Flats (L-indsley and Ross 1940). 



Nevada: Goldfield. Esmeralda County, 7,000 feet, July 27 (Chamberlin 1926). 



New Mexico: Gallinas and Water Canyons (Cockerell 1898). Jemez Mountains, 



August 4 (Chamberlin 1926). 

 Utah: Zion National Park (Tanner 1928). 



Hosts.— The larval habits are unknown, but adults were collected 

 by Tanner (1928) around western yellow pine (Pinus ponderosa 

 Lawson), and by Linsley and Ross" (1940) on California juniper 

 (Junipeims calif ornicus Carriere). 



No variation was observed in the few specimens examined except in 

 size, the length ranging from 13 to 15 mm.
