margin. Second joint of the tiagellum more than half as long- 

 again as the fir.st, the second and third subequal and rather 

 shorter than the fourth. Head subo^aaque, almost smooth, the 

 front shining, the margins of the eyes broadly bordered with 

 brilliant golden pubescence ; the eyes separated on the vertex by 

 a distance equal to three-quarters of the length of the second 

 joint of the flagellum. Pronotum depressed below the level 

 of the mesonotum, much higher in the middle than at the sides, 

 almost vertical- Mesonotum and scutellum shining and almost 

 smooth, only microscopically but very closely j^unctured ; a large 

 patch of shoi't golden pubescence on the mesopleurae below the 

 base of the anterior wings. Median segment longer than broad, 

 opaque, rather indistinctly transversely striated, the strife more 

 obscure towards the apex, a median carina from the base reaching 

 beyond the middle, vertically truncate posteriorly, the face of the 

 truncation coarsely transversely striated, with a deep median 

 sulcus. Abdomen smooth and shining, highly polished, the 

 pygidial area closely punctured ; the second ventral segment 

 strongly convex, flattened on the sides at the base and with 

 a longitudinal carina from the base not reaching the middle, 

 the apex of the first segment narrowly obliquely striated. The 

 second cubital cell is pointed on the radial nervure, and about 

 equal to the third in length on the cubital nervure ; the two 

 recurrent nervures are received before the middle of the second 

 cubital cell, the first much further from the base of the cell than 

 from the second. The tarsal ungues are long.
