joints apicaliy reddish; wings hyaline, veins and stigma, except meta- 

 carpus, costa, and base of stigma, black. Abdomen black with the' 

 apical margins of all segments very narrowly castaneous; sternites 

 and pleurites black separated by broad bands of white. 



Male. — Length, 9 mm.; antennae, 8 mm. Unusually similar to 

 the female, differing practically only in the color of the middle tarsi, 

 palpi, antennae, and face and in the lack of the two white marks 

 on the posterior edge of mesoscutum; palpi except apical joint of 

 labial palpi, which is fuscous, white; clypeus and face white, with 

 clypeal suture, median stripe on face, and a triangular mark below 

 each antenna black; antennae black, with scape as well as pedicel 

 and basal joint of flagellum white beneath; middle tarsi fuscous in- 

 stead of reddish as in female. 



Host. — Notolophus antiqua (Linnaeus). 



Type locality. — Portland, Oregon. 



Type.— Cat. No. 22876, L.S.N.M. 



Described from three females and four males reared by E. J. New- 

 comer, of the Bureau of Entomology, under Quaintance No. 14083. 



The two female para types differ from the type practically only in 

 size, peratype h being only 8 mm. long. The three male paratypes 

 differ but little from the allotype, paratj^pe d being 10 mm. long and 

 e lacking the white markings on scape and lateral margins of meso- 

 scutum. 



APECHTHIS ONTARIO (Cresson). 



Pimpla Ontario Cresson, Trana. Amer. Ent. Soc, vol. 3, 1870, p. 146, male. 

 Type, Acad. Nat. Sci. PMla., No. 1415. 



Discussion based on type, specimens compared with type by Vie- 

 reck and the writer, other specimens in the Academy of Natural Sci- 

 ences of Philadelphia and ten other specimens in the National Museum, 



Easily distinguished from pidicornis (Cresson) by the characters 

 used in the key, and also differing as follows: Antennae pale brown- 

 ish beneath; front coxae in female mostly reddish, not whitish at 

 apex, mostly whitish in male; propodeum with upper hind angles 

 not especially prominent, the lateral face of propodeum with upper 

 margin and pleural carina converging posteriorly; punctures of ter- 

 gites well separated, never confluent; averages somewhat smaller. 



Length.— Femide, 7-12 mm., male 8-10 mm. 



Distribution. — The type is from Canada. The National Museum 

 series includes specimens from Quebec, Ontario, Michigan, Vancou- 

 ver, Washington, Idaho, and California. 



Hosts. — A pair from Quebec were reared from the pupa of the 

 spruce bud worm {Tortrix fumiferana), a female reared under Hop- 

 kins No. 11100 at Pittsburg, New Hampshire, from the same host, 

 and a female from Sonoma County, California, was taken "In the act 

 of ovipositing on Tortrix on wild pea."
