type locality; one female reared by C. T. Dodd from an acorn of 

 California white oak {Quercus lohata) at Walnut Creek, Calif.; one 

 female (Hopkins U. S. No. 15637^ reared by L. H. Weld from 

 Quercus sp. at Las Vegas, N. Mex. ; one female (Hopkins U. S. No. 

 14215f ) reared by J. M. Miller from the gall of Cynips 7naculipennis 

 Gillette at Ashland, Oreg.; one female (Bureau of Entomology No. 

 168°) reared from Walskm amorpheUa Clemens, Alameda County, 

 Calif. ; and one female from Menlo Park, Calif., F. Hornung. 



There is great variation in size, the largest female being 12 mm. 

 long and the smallest male less than 4 mm. 



CALLIEPHIALTES BENEFACTOR, new species 



Very similar in form to niteicola, but differing from the description 

 of that species as follows : 



Female. — Length, 9 mm.; antennae, 7 mm.; ovipositor, 12 mm. 

 Head more distinctly punctate, face rather densely so; face hardly 

 two-thirds as long as broad; temples very narrow, convex. Thorax 

 distinctly punctate, mesoscutum rather densely so, propodeum densely 

 and more coarsely punctate, carinae represented by parallel ridges 

 flanking a longitudinal groove; nervellus reclivous, broken dis- 

 tinctly above middle. Abdomen narrow, only second tergite distinctly 

 longer than broad at base, first and third to fifth as broad as long, 

 punctation dense, tubercles rather low and hardly less densely punc- 

 tate ; ovipositor distinctly longer than body. 



Black ; scutellum piceous red ; hind tibia fuscous above, pale below ; 

 hind tarsus except extreme base entirely fuscous ; legs otherwise much 

 as in nuclcola, but dorsal stripes of middle and front tibiae less dis- 

 tinct; Avings as in nucicola. 



Male. — Face fully two-thirds as long as broad, densely punctate 

 and with short, dense pile ; abdomen only slightly more slender than 

 in female; genitalia very long and slender. 



Scape and pedicel white in front ; lateral lobes of mesoscutum, 

 subalar tubercle, and lower mesopleurum, piceous red; front and 

 middle legs, except posterior side of femora and upper side of middle 

 coxa, white; hind trochanter also largely white. 



Host. — Grapholitha nwlesta Busck. 



Type.— v. S.^.M. No. 42897, from Burlington, N. J. 



Twenty-three females and 17 males, all reared from the oriental 

 fruit moth; 14 females and 10 males from the type locality; 1 male 

 from Hopewell, N. J. ; 4 females and 3 males from Harrisburg, Pa. ; 

 3 females and 2 males from Chambersburg, Pa.; 1 of each sex from 

 Manchester, Pa.; and 1 female from Stewartstown, Pa. 



The only striking variation is in the color of the thorax in the 

 male. The allot3^pe displays about the average color, some specimens 

 having the red much brighter and embracing the entire mesosternum,
