Trichcgrammatomyia new genus. 



Ftmale. — In n\\ table to the Chcetostrichini runs to Brachy- 

 grav'.ma Girault (there is a ring-joint, the antenna' 7-jointed); 

 but the following differences: The marginal vein is not stout 

 yet net long (about six times longer tbiin wide, nearly twice the 

 length of the well-developed stigniiil); the ovipositor is inserted 

 proximad of the middle of the venter by a little; the marginal 

 fringes of the not broad fore wings are long (more or less a third 

 the greatest wing-width), the club is not much wider than the 

 funicle; the discal ciliati( n ( f the fore wing is moderate and bears 

 regular lines cephalad and caudad only. Caudal wings narrow, 

 not l(>ng, \\ith two lines of discal cilia, the caudal marginal cilia 

 as long as the marginal cilia of the fore wing. Habitus of Tricho- 

 gramma. No oblique line of seta' from the stigmal \ein. Caudal 

 femur stouter, the tarsal joints more or less equal, longer than wide. 

 Mandibles with two acute teeth and an inner oblique truncation. 



The male antenna has the flagellum filiform, only one funicle 

 joint which is nearly twice longer than wide and the club is divided 

 near the middle, the two joints about as long as the funicle or the 

 pedicel; funicle and chii) with long, stiff hairs. 



Trichcgrammatcmyia tortricis new species. C.enotype. 



hcnmJe. — Length 0.50 mm. 



Black, the fore wings dusky from base to end of the stigmal 

 vein, the \enati( n dusky. Face, \ertex, lateral margins and 

 median line of scutum and distal third of scutum (more 

 at the meson), orange yellow. Club twice longer than its greatest 

 width (at middle), a little longer than the scape, 1 hemispherical, 

 2 conical, not spined at apex, over twice the length of 1. Funicle 

 joints subequal, each o\er twice wider than long; pedicel twice or 

 m.cre the length of the funicle. F'ore wings with about twelve 

 lines ( f discal cilia where widest, the ciliation extending back to 

 the base of the marginal vein (centrally). Tarsi pale. 



Described from, one malp, and seven females frc m the eggs of 

 Tortnx cerasivorana, Guelph, Ontario, Canada, (C. J S. Bethune).
