stoutly, closely striated. The upper part of the mesopleura smooth ; 

 the base with scattered round punctures, the apex depressed, with 

 stout, oblique, clearly separated keels. Metapleura widely reticu- 

 lated, the reticulations at the base long, narrower, and more 

 irregular. Abdominal petiole smooth. Legs densely pilose ; the 

 tibiae and tarsi not spinose ; hind calcaria short, not so long as the 

 third tarsal joint. Second abscissa of radius with a straight, 

 oblique slope towards the middle of the wing, the apex of the 

 radial cellule being thus much widened, the apical abscissa has a 

 straight, slightly oblique slope ; the junction of the two forms a 

 narrow rounded angle ; the recurrent nervure is roundly curved and 

 is joined to the cubitus by a short, oblique l^ranch, from the lower 

 part of which the cubitus issues ; the cubitus beyond this is very 

 faint ; the transverse median nervure is received at a distinct dis- 

 tance beyond the transverse basal. There is a stout keel on the 

 lower part of the front. 



Comes near to E. dimidiata. 



EVANIA MEEIDIONALIS, Sp. nOV. 



Black, the flagellum of antennae dark rufous, darker coloured 

 towards the apex ; the tibiae and tarsi piceous ; wings clear hyaline, 

 the stigma blackish ; the costa fuscous, the nervures whitish testa- 

 ceous ; metasternal process diverging. Face impunctate, pilose ; a 

 distinct furrow runs down from the outer side of the antennae to the 

 mouth, the lower part curving inwardly. Mandibles brownish. 

 Eyes parallel ; ocelli separated from the eyes by a slightly greater 

 distance than they are from each other. Malar space large, about 

 two-thirds of the length of the eyes. Mesonotum and scutellum 

 smooth, almost impunctate ; parapsidal furrows deep, wide, smooth. 

 Metanotum closely, irregularly reticulated. Propleurae finely, closely 

 rugose, striated closely at the apex. Mesopleurae closely reticu- 

 lated ; the upper part coarsely shagreened, smoother, more shining 

 at the apex below. Metapleurae irregularly shagreened above ; the 

 rest reticulated, the reticulations running into striae at the apex. 

 Abdominal petiole smooth and shining above, the sides opaque. 

 Hind coxae smooth ; the tibiae not spined ; the long spur of the hind 

 tibiae reaches to slightly beyond the middle of the metatarsus, and 

 is slightly longer than the second tarsal joint. $ and <? .
