of submarginal vein, reacliing across disk of wing, obliquely inter- 

 rupted by the hairless streak, and subintorrupted below by a narrow 

 line of paler color running parallel to the posterior margin of wing, 

 the spot augmented also by character of the ciliation described 

 above; veins pale yellowish. 



Redescribed from one female of European origin but without lo- 

 cality lal)el. This species evidently varies in coloration as accord- 

 ing to Mayr the notum of thorax may be either brown or orange 

 yellow.

Female.— Front and vertex about two and one-third times as long 

 as wide; ocelli in an acute-angled triangle, the posterior pair about 

 one-half their own diameter from the eye margin; antennal scrobes 

 shallow and wide; eyes with a rather dense, but short, fine pubes- 

 cence. Antennal scape about one-third as wide as long, widest 

 beyond the middle; pedicel iibout as long as the first three funicle 

 joints combined; all funicle joints equal or nearly so in length, 

 gradually increasing in width after the second, the sixth being 

 nearly twice as wide as the first two, all wider than long; club oval 

 with truncate base and rounded apex, nearly one-half wider again 

 than the last funicle joint and as long as the last five preceding joints 

 combined. Wings not uniformly ciliated, cilia blackish on area 

 beneath stigmal vein and on apical fourth of disk, and pale or whitish 

 on an intervening curved band and on most of area beneath the 

 submarginal vein; oblique hairless streak reaching only about one- 

 half of the way across disk of wing from stigmal vein, obscured 

 below by the weak ciliation. Length: 0.8 to 1.0 mm. 



Front, vertex and mesonotum rather dull orange yellow, the meso- 

 notum frequently becoming dusky after death; face, cheeks, and 

 underparts pale yellowish white, the cheeks sometimes brighter 

 yellow and v/ith a blackish brown spot on lower corner, and the 

 middle of venter on each side of ovipositor sheath pale brownish; 

 concealed portion of the occiput and of the pronotum, the meta- 

 notum, propodeum, and dorsum of abdomen blackish brown, the 

 latter with a broad, transverse whitish band near base nearly or 

 quite interrupted in the middle, and with a lateral, submarginal 

 white streak behind the vibrissal plates; collar of pronotum and teg- 

 ulae whitish, each with the usual brown dots. Antennal scape, 

 base of pedicel, first three funicle joints and club black, the scape 

 with base, apex and a narrow line on the upper margin of the outer 

 face white, but on inner face the white expands and covers whole 

 surface except a large spot on lower apical corner; apex of pedicel
