rowed in front, the recurrent nervure received at the apex of 

 the basal third ; the transverse median nervure almost inter- 

 stitial ; the radius issuing from near the apex of the stigma, 

 which becomes gradually thickened towards it ; transverse 

 median nervure in hind wings unbroken. Parapsidal furrows 

 absent; the pleural furrow distinct at the basal half. Scutellum 

 roundly convex. Median segment regularly areolated ; the 

 petiolar area longish triangular, joined to the areola by a 

 longish pedicle ; the areola longish horse-shoe-shaped ; spira- 

 cles short-oval, about twice longer than wide. Abdomen 

 smooth, shining, the petiole becomes gradually widened from 

 the middle, it is longish, has a short, broad ovipositor. Cly- 

 peus net separated. Claws small, simple. Antennae long and 

 slender, densely, shortly pilose. Tibiae spinose. The spira- 

 cles on the 1st abdominal segment are placed shortly, but 

 distinctly beyond the middle. Ocelli distant from the eyes. 

 Temples wide, obliquely narrowed ; the occiput rounded 

 inwardly. There are no lateral keels on the 1st abdominal 

 segment ; the spiracles on the latter are placed shortly beyond 

 the middle. The radial cellule is long, narrow, extending close 

 to the apex of the wing. There are 5 large areœ on the apex 

 of metanotum or 10 in all. 



May be known from Mesochorus Gr. by the longer, narrower 

 radial cellule and stigma, by the more completely areolated 

 metanotum, with its longish, not roundish spiracles. 



Edrisa pilicornis sp. nov. 



Pale testaceous, the metanotum more reddish in tint, the 

 antennae, the front, except on the sides, vertex, upper part of 

 occiput, mesonotum, base of scutellum, and the abdomen 

 black ; the base of l^t abdominal segment dark rufous, the 

 apical half of the 2"^^ segment and a square indentation on 

 the black base, pale yellow ; legs yellowish testaceous, the
