and very shallow; surface densely, finely punctate, more densely punctate and 

 rugose basally, rather densely clothed with moderately long, erect, white hairs. 

 Each elytron with three more or less distinct, vaguely elevated costae; first 

 smooth, straight, distinct, extending along sutural margin from apex to in front 

 of middle ; second smooth, short, extending from median fovea backward but not 

 reaching apex ; third scarcely indicated, not smooth, and following outline of 

 lateral margin ; and with three slightly cupreous foveae, one on disk in front of 

 middle, one behind middle toward lateral margin, and one at apical third inter- 

 rupting first costa. 



Abdomen beneath coarsely, sparsely punctate, smooth along posterior and 

 anterior margins of segments, sparsely clothed with rather short, erect, incon- 

 spicuous hairs, and with smooth, indistinct, but not elevated, lateral callosities ; 

 last visible sternite broadly, deeply, arcuately emarginate at apex, without a 

 submarginal ridge, lateral margins coarsely serrate; eighth tergite sparsely, 

 coarsely punctate, broadly, shallowly, arcuately emarginate at apex. Prosternum 

 coarsely, densely punctate, more or less rugose, sparsely clothed with long, recum- 

 bent, whitish hairs ; anterior margin with a broad, short, median lobe. Anterior 

 femur with a short angulated tooth, which is feebly dentate on outer margin. 

 Anterior tibia arcuate, with a moderately long, rounded dilation at apex ; middle 

 and posterior tibiae straight. 



Length 8.25 mm., width 3.25 mm. 



Kedescribed from the male type in the collection of H. C. Fall 

 (Museum of Comparative Zoology). 



Female. — Differing from the male in having the head uniformly reddish cupre- 

 ous, the last visible sternite broadly, shallowly, arcuately emarginate at apex, 

 the eighth tergite more densely, coarsely punctate, and anterior tibia unarmed 

 at apex. 



Type locality.— -Mt. Wilson, Calif. 



DISTRIBUTION 



From material examined 



California: Mt. Wilson, June 14-16, 1903, type series (H. C. Fall). Gray 

 Meadow, Tulare County, June 1926 (H. F. Wickham) ; July 5, 1913. 



Also recorded in the literature from the following localities : 



California : Sierra Madre ; Lake Tahoe ; Tuolumne and Shasta Counties. Fall 

 (1907) records it as not rare in the Southern Sierras at altitudes of 3,000 to 

 6,000 feet. 



Oregon: Mt. Jefferson, July 20, 7,500 feet (Chamberlin 1925). 



Hosts. — The larval habits are not known, but Fall (1907) reports it 

 as occurring most commonly on scrub oak (Quercus dumosa Nuttall), 

 and Chamberlin (1917) records it as probably breeding in the smaller 

 limbs of Jeffrey pine (Plnus jeffreyi "Oreg. Com.") and yellow pine 

 (Firms ponderosa Lawson) . 



Very little variation was observed in the few specimens examined. 

 The foveae on the disk of the elytra vary in color from reddish cupre- 

 ous to bronzy green. In the specimens from Gray Meadow the prono- 

 tum is widest in front of the middle and the lateral margins strongly 

 converge posteriorly. The last visible abdominal sternite of the fe- 

 males is usually shallowly emarginate at the apex, but in a few exam- 

 ples it is vaguely notched. The front of the head is usually reddish 

 cupreous in the females, but in one of the examples from Gray Meadow 

 it is bronzy green with a distinct cupreous tinge. The length is from 

 7 to 9 mm. 



This species is allied to fragariae Fisher, but it differs from that 

 species in having the pubescence slightly longer and the foveae on 

 the elytra very distinct.
