CHALCID FLIES OF GENUS PERILAMPU3 — SMULYAN 403 



apically and occupying about one-third to somewhat more than one- 

 half of scape, sensoria usually coarse or moderately coarse. 



TVp^.— U.S.N.M. no. 22886. 



Redescribed from a large series of specimens of both sexes including 

 the type, which is a male from eastern Florida. 



Distribution. — Widely distributed and apparently a rather common 

 species. I have seen material from the District of Columbia and 

 two or three provinces in Canada, including British Columbia (June), 

 and from the following States: Maine (June, July); New Hampshire 

 (July, Aug., Sept.); Massachusetts (July, Aug.); Rhode Island (Aug.); 

 New York (July, Aug.); New Jersey (July to Oct., inch); Pennsyl- 

 vania (July, Aug., Sept.); Delaware (June, Aug.); Maryland (June 

 to Sept., incL); Virginia (July, Aug., Sept. "captured on tliistle"); 

 Florida (July); West Virginia; Oliio (April to Sept., incl.); Michigan; 

 Indiana (Aug., Sept.); Illinois (April, July, Aug.); Missouri (July); 

 Arkansas (July); Louisiana; Kansas (Aug.); Oklahoma; Texas (May 

 to Dec, inch); Colorado (Aug.); Nevada (July); Wasliington (May); 

 California. 



Hosts. — Zenillia (Exorista) sp., Ascogaster sp., Cremastus cooki 

 Weed, Meteorus sp., Apanteles sp., Macrocentrus pallisteri De Gant, 

 ''hymenopterous cocoons," 



The species has been reared in association with a number of lepidop- 

 terous insects, but very likely it was hyperparasitic. 



PERILAMPUS FULVICORNIS PROTHORACICUS, new variety 



Female. — Length about 2-3 mm. Differs from. fulvicornis Ashmead 

 in three essential respects: (1) Anterior edge of pronotum at lateral 

 angles depressed, the punctate portion of pronotoprepectal area at 

 dorsal margin short, seemingly occupying distinctly less than half 

 the distance between anterior edge of pronotum and the tegula of 

 wing; (2) basal shallow furrows on underside of apex of scutellum not 

 turning caudad medially or turning caudad only slightly and meeting 

 on the median line to form a single more or less curved furrow or an 

 obtuse angle; (3) neck of propodeum weakly sculptured, only rarely 

 coarsely sculptured. 



Other differences are as follows: Area along inner margins of parap- 

 sides usually rather distinctly sculptured or roughened; interspaces 

 between unbilicate punctures on scutellum apparently always entirely 

 finely reticulated; base of extension of axilla on side of scutellum 

 sometimes not quite reaching to middle of axilla; wing hairs, post- 

 marginal vein, and stigmal vein usually long; head often with a 

 greenish tinge and sometimes distinctly greenish; thorax often a 

 gray metallic black, the areas along inner margins of parapsides rarely 

 bronzy; abdomen often with a distinct gray reflection; wings rarely 

 with a very faint brownish cloud beneath marginal vein.
