A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 169 



Kedescribed from the male type, No. 2698, in the Museum of Com- 

 parative Zoology, Cambridge, Mass. 



Female. — Differing from the male in having the antenna uniformly brownish 

 cupreous, the last visible sternite more elongate, and broadly, shallowly, arcuately 

 emarginate at apex, the eighth tergite more coarsely punctate, the prosternum 

 sparsely punctate and sparsely pubescent, the anterior tibia slightly arcuate and 

 unarmed at apex, and the middle tibia straight. 



Type locality. — California, no definite locality. 



DISTRIBUTION 



From material examined : 



California: No definite locality, type (Andrew Murray). Confidence, August 20, 

 1919, reared (R. D. Hartman). Northfork, May 16, 1928 (A. Wagner). 

 Yosemite, September 1914 (J. J. Sullivan). 



Also recorded in the literature from the following localities, but 

 some of these records may not refer to this species, as specimens have 

 been so often misidentified in most collections : 



California : Castella, and Nevada County (Chamberlin 1917) . San Diego County 

 (Blaisdell 1892) (not this species). Southern Sierras and San Bernardino 

 Mountains (Fall 1894, 1901) (this is monticola). Placer County, near Towle, 

 Dutch Flat, and Alta (Wright and Coolidge 1908). Lassen National Forest, 

 5,500 to 6,500 feet, June (Lange 1937). 



Nevada: No definite locality (Horn 1886) (not this species). 



New Mexico: Coolidge and Santa Fe, 6,975 feet (Cockerell 1898) (identification?) 



Hosts. — This species has been reared from western yellow pine 

 (Pinus ponderosa Lawson) collected at Confidence, Calif., by R. D. 

 Hartman. The larva mines in and under the bark, and pupates in 

 the outer wood. Lange (1937) records it in the wood of trunks and 

 branches of Jeffrey pine (Pinus jeffreyi "Oreg. Com."). Blaisdell 

 (1892) reports it as extremely injurious to apple trees, but Chamber- 

 lin (1926) examined these specimens and found that they were not 

 californica. 



The sculpture on the dorsal surface of the body is rather constant, 

 but the specimens are somewhat variable in shape, and the color in 

 the depressed areas on the dorsal surface varies from purplish cu- 

 preous to brownish cupreous. In a few specimens examined the 

 clypeus is narrowly notched at the middle of the emargination, and 

 the pronotum is widest at the basal fourth. The length is from 

 15 to 17 mm. 



LeConte (1859) described the species from a single male collected 

 in California by Andrew Murray. Horn (1886) had a number of 

 species confused under californica, and his redescription has caused 

 much confusion, and at least in part applies to monticola Fall. He 

 placed it in the group with lobed prosternum, but the type is without 

 a median lobe, and the dilation on the anterior tibia of the male is 

 incorrectly described and figured, as is also the clypeus. He also sup- 

 pressed vulcanica LeConte as a small form of californica, but this is 

 not correct, as vulcanica seems to be a valid species.
