$. Black, shining, a broad line, rounded in front, transverse above, and of equal width throughout in 

 the centre of the clypeus, tubercles, and a line on the basal half of the anterior tibiae cream-white. Wings 

 fuscous-violaceous, the nervures and Stigma black. L. 9 mm. 



Vertex sparsely punctured, almost transverse behind; temples longer than the antennal scape, longer than 



usual, rounded. Ocellar region raised. From the ocelli a deep, clearly defined furrow runs to the antennse; its 



basal half much wider than the apex, forming an elongated oval, with obliquely sloped sides; the apical border 



narrow, furrowed by stout keels; this apical part is clearly raised; its sides obliquely sloped, and coarsely and 



irregularly punctured. Face coarsely punctured, the sides more closely than the centre; the clypeus smooth, 



except for some round punctures bordering the white line and on the sides below. Mandibles and labrum 



impunctate; the latter covered with long white hair, slightly tinged with fulvous. There are three impressed 



lines on the basal half of the mesonotum ; these are bordered by some punctures, apical slope closely and strongly 



punctured. Basal half of scutellum sparsely, apical closely punctured, as is also the postscutellum, except 



narrowly in the centre. Basal area of metanotum coarsely aciculated, opaque, the rest almost smooth; mesopleurae
