Family Trichogrammatidae. 



Subfamily Oligositinae. 

 Tumidifemur geniis novum. 



Normal position. 



F e m a 1 e: — Head normal, the Vertex wide, bearing the three 

 ocelli in a curved line across the vertex, the lateral ocelli not touching 

 the eye margin, the antennae inserted GÜghtly below (ventrad) the 

 middle of the face but ßlightly dorsad of an im.aginary line drawn 

 between the ventral ends of the eyes, 6-jointed — scape, pedicel, 1 ring- 

 joint and a 3-jointed club, the latter with scattered stiff pubescence 

 which is not very long; scape not reaching to the cephalic ocellus, 

 straight, cylindrical, distinctly longer than the pedicel; the latter 

 rather stout, obconic, not much longer than wide; ring-joint usually 

 hidden, shallow; club rather stout ovate, short, composed of three 

 rather indistinct, u.nequal joints, subequal in length to the scape. 

 Mandibles tridentate, all of the teeth acute. Parapsidal furrows com- 

 plete; abdomen short, obtusely conical, not longer than the thorax, 

 the ovipositor and its valves concealed beneath the venter, not exserted 

 or projecting slightly at tip. Legs normal but the caudal femora enlarged 

 and longitudinally striated, twice the width of the others, elliptical 

 oval and shorter than their tibiae, about tv/ice longer than broad; 

 tarsi 3-jointed, the joints all short, lengthening slightly distad; tibial 

 spurs Single, absent on the cephalic tibia, consequently the strigils 

 absent, elsewhere short and straight, acute. Trochanters 2-jointed. 



Fore wings moderately broad, pyriform in general outline, enlargmg 

 regularly distad, the apex rather oblately rounded, broadest at the 

 distal cighth, densely normally ciliate discally, the marginal cilia all 

 very short, barely longer than' the discal cilia which are short and 

 fine; marginal cilia around wing apex nearly uniform, exceedingly 

 short along each margin, there closer and barely visible; a conspicuous 

 oblique hairless line dividing the discal ciliation and running proximo- 

 caudad from the stigmal vein as in Aphelintts Dalman, but no oblique 

 line of discal cilia. Proxiraad of this line the discal ciliation is absent 

 excepting a small triangulär area of about four or five lines against 

 the marginal vein and two isolated cilia against the submarginal vein 

 proximad of its break ; two thirds the way down a short spur is given 

 off from the hairless line, entering the discal ciliation. Fore wing 

 uniformly slightly fumated proximad out as far as the end of the 

 stigmal vein and the discal ciliation included by the fumated area is 

 about twice coarser than the main part of the ciliation distad. 

 Venation straight; submarginal vein very narrow, breaking distad 

 and then as wide as the marginal, slightly longer than the marginal; 

 the latter long, somewhat over a fourth the wing length, not broad; 

 postmarginal vein absent; stigm.alvein distinct, normal, with a distinct, 

 short neck and a slender uncus, its knob rounded-oval. Venation 

 bearing six or seven large setae. Posterior wings broad, their blade 

 knife-shaped, the cephalic margin straight, the caudal margin curved
