anteriorly, posteriorly usually with some weak \vrinkling and punc- 

 tures; upper surface of hind coxa smooth and polished; tarsal claws 

 each with three teeth; ovipositor sheath about 1.4 as long as the 

 forewing. 



Female: Ferruginous. An oblique blackish triangle projecting in- 

 ward and backward from the eye toward the lateral ocellus (fig. 16, j) ; 

 labial palpus and maxillary palpus, especially basally, infuscate; 

 flagellum blackish ; thorax often with small infuscate areas on the inner 

 part of the lateral lobe of the mesoscutum, on the sterna, and some- 

 times elsewhere; wings heavily tinged with reddish brown, the fore- 

 wing darker at the apex and with a large conspicuous dark brown 

 mark below the stigma (fig. 15, i). 



Male: Colored Uke the female except as follows: Head largely to 

 entirely black; pedicel blackish; thorax largely to almost entirely 

 black, but always with at least the median lobe of the mesoscutum 

 partly ferruginous laterally; middle and hind coxae more or less ex- 

 tensively blackish basally; usually a dorsal basal stripe on first tergite, 

 a subapical triangle on each side of second tergite, fourth tergite 

 dorsally, fifth tergite except ventrally, and most or all of sixth and 

 seventh tergites black. The apical and substigmal wing marks are 

 somewhat smaller and weaker than in the female. 



Type: U. S. N. M. No. 58825, 9, Kooskooskie, near Walla Walla, 

 Wash., July 15, 1932, M. C. Lane (Washington). 



Paratypes: 18 cf , 27 9, from British Columbia (Hundred Mile 

 House, Robson, and Wellington); California (Big Flat on Coffee 

 Creek in Trinity County and Carrville in Trinity County at 2,400 to 

 2,500 feet); Idaho (Post Falls and Priest River Lake); Montana 

 (Missoula) ; Oregon (Cascadia, Lucky Boy Camp on the Blue River, 

 Parkdale, Suttle Lake at 3,435 feet, and Triangle Lake in Lake 

 County); and Washington (Blue Mountains, Dayton, Kooskooskie 

 near Walla Walla, Mill Creek near Walla Walla, and Wolf Fork on 

 the Touche River). Dates of capture are distributed from June 10 

 to September 1. A female from Priest River Lake, Idaho, was taken 

 while flying about Pinus contorta. Two other specimens were reared 

 as follows: cf , from Leptura obliterafa in Pinus ponderosa, Missoula, 

 Mont., June 10, 1914, H. B. Kirk; 9, from Pinus ponderosa infested 

 with Leptura obliterata, L. plagifera, and Anoplodera sanguinea, Priest 

 River Lake, Idaho, July 20, 1902, A. D. Hopkins. 



This species occurs in British Columbia and the Northwestern 

 United States. It parasitizes lepturine cerambycids in Pinus. Rec- 

 ords indicate that it occurs often at lower altitudes than does the simi- 

 lar appearing Aulacostethus occidentalis. The specific name is proposed 

 in honor of H. R. Foxlee, who collected a number of specimens at 

 Robson, British Columbia, and whose other collections have been 

 doing much to make known the insect fauna of that vicinity.
