 Frontal depression finely, closely transversely, regnlarly striatal to the anterior ocelhis, which

 wings hyaline, venaticui black. Frontal de|)ression closely, regularly, not very strongly 

 striated, sejiarated from the anteriiu- ocellus by a smooth, sliglitly curved, flat keel; it is 

 sejiarated from the eyes by a broad band which, on the inner side, bears three rows of 

 punctures lielow. two above; the inner side is obliquely depressed towards the eyes and has 

 t\vo rows. Thorax on the ]iro- and mes(umtum and scutellnm closely, regidarly not very 

 strongly punctured; ajiex of scutellum margined, the centre with the keel stronger and 

 depressed in tlie middle, forjiiiug two slight lolics n:irrowed inwardly. The centre of the 

 metanotum has, ou either side. !i stout keel, which runs from the outer basal part to the inner 

 central, the two forming a large triangular area. Closely, ahnost unif(M'mly, not very strongly 

 ]iunctured. The luirroweil apical part of the scntellum margined, furrowed on the inner 

 side, the centir of the apex broadly biloliate, the lobes not [irominent. The depressed part 

 of the metanotum striated, the striic moderately strong, more or less curved, bordered at 

 base and apex by a snmoth margin. Abdomen as hmg as thorax, terminal sheath short,
