A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 191 



these records refer to some of the closely allied species which are 

 confused under carinipennis in most collections. 



Hosts. — Bedard (1938) reports that Burke identified the larvae col- 

 lected beneath the bark of Douglas fir (Pseudotsuga taxifolia (La- 

 Ma rck) Britton) during October in Idaho as this species, and the 

 adults have been collected by Hofer in Arizona and by Burke in 

 Utah on this host plant. The species has been recorded in the lit- 

 erature from western yellow pine (Pinus ponderosa Lawson), sugar 

 pine (Pinups lambertiana Douglas), loclgepole pine {Pinus contorta 

 Loudon), pihon (Pinus edulis Engelmann), and western larch (Larix 

 occidentalis Nuttall), but on account of the number of other species 

 confused under carinipennis these host records should be verified 

 before being accepted. 



The color in the punctured areas on the dorsal surface of the body 

 varies from reddish cupreous to bronzy green, and on the front of 

 the head in the males from green, through yellowish green, to red- 

 dish cupreous. The clypeus is usually arcuately, rarely angularly, 

 emarginate in front. The sculpture on the pronotum is more or less 

 variable, and the sides are usually parallel and more or less sinuate 

 at the middle, but occasionally specimens are found with the pro- 

 notum widest near the apical angles, and the sides strongly, obliquely 

 converging posteriorly. The prosternum is sometimes smooth at the 

 middle and more or less rugose toward the sides. The length is from 

 10.5 to 13 mm. 



This species was described by LeConte from a single male. Horn 

 (1886) records it from Colorado and Nevada, but does not mention 

 the type locality Utah ; in fact, the specimens mentioned by him from 

 Colorado are not this species.

Male. — Moderately elongate, rather strongly depressed above, strongly shin- 

 ing, piceous on the smooth elevated spaces, bronzy green in the punctured 

 areas ; beneath dark green, slightly purplish at sides. 



Head uniformly bronzy green, with two small callosities on front, and a dis- 

 tinct, smooth, longitudinal carina on occiput • front flat ; surface coarsely, deeply, 

 confluently punctate, rather densely clothed with long, erect, inconspicuous 

 hairs; clypeus broadly, deeply, subangularly emarginate in front, arcuately 

 rounded on each side. Antenna bronzy green, slightly piceous at outer margins 

 of segments, gradually narrowed to apex ; intermediate segments not compact, 

 subtriangular, as long as wide, broadly subtruncate at outer margins ; third 

 segment one-third longer than fourth. 



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

 apex, widest along middle ; sides parallel and slightly sinuate at middle, 

 slightly converging at base and apex; anterior margin rather strongly sinuate, 

 with a small, broadly rounded, median lobe; base broadly, arcuately emarginate 

 on each side, the median lobe slightly produced, and narrowly truncate in front 

 of scutellum ; disk moderately convex, with a broad, longitudinal, densely punc- 

 tured, median sulcus, limited at each side on apical half by a broad, elevated, 

 smooth callosity, and on each side midway between this callosity and lateral 

 margin an irregular, smooth, longitudinal callosity, which is broadly interrupted
