Male. — Essentially as in female. 



Type.— C^i. No. 24960, U.S.N.M. 



Type locality. — Vernon, British Columbia. 



Host. — Olene vagans Barnes and McDunnough. 



Described from 14 female and male specimens labeled as bred 

 from Olene vagans hy E. P. Venable. Six of ihQ paratype specimens 

 are in the Canadian National Collection at Ottawa; the remainder 

 of the type material is in the United States National Museum in 

 Washington. 



APANTELES MIMORISTAE. new species. 



Vei-y similar to anstotelme, agreeing in general appearance, in 

 color, and in the length of the ovipositor. It differs from that species, 

 however, in the first abdominal tergite, being distinctly narrower at 

 apex than at base, in the much smoother second abdominal tergite, 

 and in the whiter wings, with the stigma brown only in the margins. 



Female.— L&ngih. 2.5 mm. Head transverse ; face closely punctate ; 

 antennae shorter than the body ; vertex closely punctate and opaque ; 

 mesoscutum very closely punctate, dull ; disk of scutellum flat, punc- 

 tate and opaque ; mesopleurae opaque, mostly punctate ; propodeum 

 rugulose, with a rather well-defined median areola, which is smooth 

 and shining within ; costulae indistinct ; inner spur of posterior tibiae 

 more than half as long as the metatarsus; first abdominal tergite 

 narrowing decidedly on apical third, distinctly narrower at apex 

 than at base, closely finely ruguloso-punctate, with a longitudinal
