$. Black, shining, a broad line, rounded in front, transversc 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 antennas; 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 

 irreg^arly 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, shghtly 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
