unmarked except for a brownish streak on upper side of hind tibiae 

 near their base, and tip of last joint of tarsi blackish. Wings with 

 a large, tegumentary, Jarown band across the disk beneath the mar- 

 ginal vein, extending distad to end of stigmal vein with a convex 

 margin, separated from the very slightly dusky apex of wing by 

 the band of colorless cilia and broken below by a narrow, pale line 

 running parallel and close to the posterior margin of wing; extreme 

 base of wing also infuscated; the veins unusually dark brown. 



Described from one female (type) reared from Pulv'iTUiria sp.,

Female. — Front and vertex twice as long as wide; 'ocelli in an 

 equilateral triangle, the posterior pair a little over one-half their 

 own diameter from the eye margin; antennal scrobes distinct, nar- 

 row, converging above but not uniting; eyes with a fine, short 

 pubescence. Antennae lost in single available specimen, but the 

 scape is described as non-expanded by European authorities. Wings 

 not uniformly ciliated, the cilia weak and transparent in a broad, 

 curved band at the end of the stigmal vein, and on the basal part of 

 wing beneath the submarginal vein, proximad of the band the cilia 

 beneath marginal vein strong and dark colored, and on apex of wing 

 moderately developed; oblique hairless streak rather indistinct 

 above, interrupted at the middle with the lower part expanded but 

 separated from posterior margin of wing by a few weak, colorless 

 cilia. Ovipositor protruded about one-half the length of abdomen. 

 Length: 1.1 mm., exclusive of ovipositor. 



Head entirely ferrugineous orange yellow; upper parts except a nar- 

 row whitish line on collar of pronotum blackish brown, with the sides 

 of mesoscutum orange yellow, and the axillae, metanotum and propo- 

 deum paler brown; underparts of thorax orange yellow, with the 

 mcsopleura slightly brownish and the metapleura entirely blackish 

 brown; venter of abdomen blackish brown, contrasting with the 

 orange yellow exserted portion of the ovipositor; tegulae whitish 

 with the posterior margin brown. Antennae described by European 

 authorities as having the scape dusky ferrugineous, the flagellum 

 brownish except the club which is yellowish white. Legs pale yel- 

 low with the middle and posterior tibiae more or less pale brownish 

 except at apex, and tip of last joint of all tarsi brown. Wings with 

 a large, tegumentary, brown spot beneath stigmal and apical fourth
