ICHNEUMON-FLIES — GELINAE I MESOSTENINI 69 



brown; flagellum with a white band, interrupted below, that covers 

 about 5.5 segments; tegula dark brown; subtegular ridge sometimes 

 white ; metapleurum usually with a round postmedial ferruginous area ; 

 propodeum often ferruginous apicolateraUy ; front and middle legs 

 fulvoferruginous, sometimes with some weak infuscation, sometimes 

 the front coxa mostly fuscous, their tarsi brownish apically and the 

 basal 0.15 of their tibiae whitish; hind coxa, trochanters, and femur 

 ferruginous, the apical 0.3 it of the femur usually infuscate; hind tibia 

 dark brown, its basal 0.2 white; hind basitarsus brown, its base and 

 apex whitish; segments 2-^ of hind tarsus white; segment 5 of hind 

 tarsus dark brown; segments 1-3 of abdomen ferruginous, the first 

 sometimes a little infuscate basally; tergites 4-7 of abdomen black, 

 the fourth often partly ferruginous laterally and the seventh with a 

 median apical white spot. 



Type: 9, reared from cocoon of Trichiosoma spicatum Ithaca, 

 N.Y., 1936, H. Townes (Washington, USNM 63753). 



Paratypes (75 cf, 739): From Alberta (Edmonton); British Colum- 

 bia (Robson, and Scotch Creek near Celista) ; Colorado (Phantom 

 Valley in Rocky Mountain National Park at 9,400 ft.) ; Idaho (Wal- 

 lace) ; Maine (Northeast Harbor and Turner) ; Massachusetts (Cum- 

 mington); Michigan (George Reserve in Livingston Co., Marquette 

 Co., Midland Co., Ogemaw Co., and Osceola Co.); Minnesota (Plum- 

 mer) ; New Jersey (Moorestown) ; New York (Bemus Point, Breesport, 

 Ithaca, New Russia, Saranac Lake, and Syracuse) ; Ontario (Chalk 

 River, Ignace, Merivale, and Ottawa) ; Quebec (Aylmer, Covey 

 Hill, Montigny, Montreal, Quebec, and Sweetsburg) ; and Washington 

 (Pullman and Yaldma City). 



The dates of collection are rather evenly distributed from early 

 summer to early fall. The earliest and latest dates of collected 

 specimens are: June 2 at Aylmer, Que., and September 6 at Robson, 

 B.C. Specimens loiown or suspected to have been laboratory reared 

 are recorded as early as March. 



Reared lots include 4 rearings from Trichiosoma triangulum, 1 

 from T. tayloril, 1 from Trichiosoma s-p., 2 from Clavellarius americanus, 

 1 from saw^y cocoon on Crataegus, 1 from sawflj^ cocoon on Castanea, 

 1 from gall on Rosa, and 1 from Archips cerasivoranus. It is presumed 

 that the host records of a gall and Archips are errors and that the 

 species normally parasitizes only clavellariid cocoons. About eight 

 specimens, including both sexes, usually emerge from a single host 

 cocoon. They cut several exit holes while emerging. 



This subspecies is transcontinental in the Transition and Canadian 

 zones.
