TWO GENERA OF CHAiLCID-FLIES — GAHAN 359 



blackish; anterior legs including their coxae yellow; middle legs 

 brownish yellow; posterior legs dark brownish with aeneous reflec- 

 tions, the apices of their coxae yellowish; wings hyaline; abdomen 

 black with the short petiole and base of following tergite yellow. 



Structurally similar to longiceps but with head not perpendicularly 

 truncate behind ; lateral ocellus about twice its own diameter in front 

 of occipital margin and not more than half its diameter from eye mar- 

 gin ; distance between lateral ocelli a little less than twice the distance 

 from lateral ocellus to anterior ocellus; malar space equal to about 

 half the height of eye; scape subcylindrical, not thickened, and not 

 quite attaining level of front ocellus; pedicel more than twice as long 

 as thick; ring joint short; first funicular segment a little shorter than 

 pedicel, last segment about as broad as long; club about as long as 

 two preceding segments. Whole head with nearly uniform, close, 

 fine, and shallow punctate sculpture. 



Pronotmn short, conical; mesoscutum a little broader than long, 

 narrowing and rounded anteriorly; parapsidal grooves traceable but 

 very shallow ; axillae narrowly separated ; scutellum moderately con- 

 vex, a little shorter than mesoscutum, rounded at apex ; propodeum less 

 than half as long as scutellum, without carinae or grooves, bare medi- 

 ally but densely hairy laterad of spiracles. Dorsum of thorax sculp- 

 tured like head, and clothed with short pubescence ; pleura more weakly 

 sculptured and more shining. Marginal vein of forewing a little more 

 than twice as long as stigmal vein and a little longer than postmar- 

 ginal; base of wing nearly uniformly ciliated but more sparsely so 

 than remainder of surface. Anterior femur slightly enlarged, straight 

 above, nearly evenly rounded beneath ; hind femur moderately broad, 

 straight beneath, evenly rounded above ; hind tibia compressed, not so 

 broad as femur. Abdomen nearly as long as thorax, and a little nar- 

 rower, elongate-elliptical in outline, and very v.eakly reticulated. 



Type locality. — Beverly, N. J. 



Type.—\5. S. N. M. No. 56653. 



Reinarhs. — Described from 32 females and 1 male. Twenty-four 

 of these specimens were received from the Oriental Fruit Moth Lab- 

 oratory, at Moorestown, N. J., and of this number 20 are labeled as 

 having been reared from Grapholitha molesta (Busck). It is evident, 

 however, that at least 8 of these were not primary parasites of the 

 fruit moth, since cocoons of Macrocentrus from which they had 

 obviously emerged were pinned with the specimens. It is possible 

 that in some instances the species was actually a primary parasite 

 of Grapholith-a. Localities represented in the Oriental Fruit Moth 

 material were Beverly, Masonville, Moorestown, Parry, Evesboro, and 

 Burlington, N. J. The 4 other specimens received from the Moores- 

 town Laboratory bear the following data : 1 from Farmington, Conn.,
