ART. 14 THIETEEN" NEW ICHNEUMON-FLIES CUSHMAN 11 



Described from two females and one male received from the Pro- 

 vincial Museum of British Columbia and reared November 22, 1925, 

 by G. A. Hardy. The female paratype is returned to the Provincial 

 Museum of British Columbia. 



CHELONUS (CHELONELLA) PECTINOPHORAE, new species 



Very similar to husseyi Viereck, but differs constantly, so far as 

 the available material goes, in several details of structure. 



Female. — Length, 3 mm.; antennae, 2 mm. Head from above 

 broadly transverse, temples strongly convex, occiput rather shallowly 

 excavated, the arc of its curvature hardly a quarter circle; vertex 

 behind ocelli, temples, cheeks, and sides of frons minutely striate, 

 opaque; frons medially subopaque, weakly impressed; eyes parallel 

 within, about three-fourths as long as width of face; face minutely 

 granularly opaque; clypeus more shining than face, minutely punc- 

 tate; malar space much longer than basal width of mandible; an- 

 tennae 16-jointed, only slightly thickened beyond middle, all flagellar 

 joints longer than thick but the subapical ones only slightly so. 

 Thorax robust; pronotum reticulate-rugose; mesoscutum shining, 

 finely reticulate-punctate, prescutum medially and the notauli cari- 

 nate, area in front of scutellum reticulate-rugose, the longitudinal 

 rugae very irregular and only a little stronger than transverse rugae ; 

 scutellum subpolished, more or less rugose around margins, lateral 

 areas foveolate with a broad polished margin; metanotum in the 

 form of a broad, foveolate groove, pleura reticulate-rugose; propo- 

 deum very coarsely reticulate-rugose above, more finely so behind, 

 the basal middle somewhat elevated, apophyses very small; basal 

 abscissa of radius shorter than second, strongly curved and joining 

 the second at a distinct angle. Carapace rather narrow, nearly two 

 and a half times as long as broad, broadest near apex, densely pilose 

 apically, longitudinally rugose, the rugosity becoming reticulate 

 toward apex, at middle with about 18 rugae, basal carinae strong, 

 converging posteriorly, extending on to the horizontal surface and 

 setting off a more finely striate basal area ; ovipositor not surpassing 

 apex of carapace, very slender. 



Black with basal two-fifths of abdomen, except basal area, white; 

 scape ferruginous; palpi pale testaceous; hind legs black, apex of 

 coxa and trochanters pale testaceous, broad annulus on tibia and tar- 

 sal joints except apices whitish; middle legs piceous and front legs 

 largely ferruginous with same pattern as hind leg; wings hyaline 

 with a pale fuscous cloud below stigma, stigma and veins dark brown 

 with basal vein, base of stigma, bases of longitudinal veins, entire 

 submedius, and all veins in hind wing whitish. 



Male. — Antennae nearly as long as body, slender, 24- jointed; 

 apical incision of carapace broadly transverse, about four times
