Thorax and abdomen normal, the parapsidal furrows com- 

 plete, distinct ; abdomen slightly longer than the thorax, 

 the ventral valves very slightly exserted ; ovipositor not 

 exserted. Sculpture of the body not marked. Abdomen 

 sessile. 



Fore wings not short and broadly rounded as in some 

 genera of the Trichogrammatinas but shaped as in many of 

 the Aphelininas {Prospaltella Ashmead), its blade being long- 

 pyriform and gradually rounded at the apex, moderately nar- 

 row, its discal ciliation dense, normal, not at all arranged in 

 regular lines, totally absent proximad of the distal end of 

 the venation with the exception of a short triangular projec- 

 tion of it proximad along the caudal margin ; marginal cilia 

 of fore wings moderate to moderately long ; fore wings deeply 

 clouded proximad, the fumated area continuous, uniform and 

 reaching distad slightly into the discal ciliation and slightly 

 beyond (distad) the apex of the venation; remaining por- 

 tion of fore wing hyaline. Venation of the fore wing straight, 

 the marginal vein short, straight, clavate, stout, slightly 

 shorter than the narrow submarginal vein which broadens 

 slightly proximad, the postmarginal vein absent, the mar- 

 ginal vein apparently obliquely truncate at its apex, but in 

 reality curving concavely caudo-distad ending in a nipple- 

 like point to form the apex of the very short stigmal vein. 

 Blade of the posterior wings linear, subacuminate, with three 

 true lines of discal cilia, including the usual single row along 

 each margin among the bases of the marginal cilia both of 

 which are away somewhat from the margins ; the marginal 

 cilia short along the cephalic margin, longer and slenderer 

 along the caudal margin, somewhat longer than the greatest 

 width of the wing ; posterior wings fumated proximad. 



Legs normal, the distal tarsal joint slightly longer than 

 either of the other two, tarsi bearing a pair of tarsal claws 

 each, hidden from above. Mandibles with at least two equal 

 acute outer teeth, and if a third inner (mesal) tooth is pres- 

 ent, it is much shorter and less acute. 



Male. — The same, but differing notably in the discal cilia- 

 tion of the fore wing, which has a broad naked band across it
