semitransparent projection, extending equally on both 

 sides of the tegular. Behind the eyes there is a sharp keel 

 extending their entire length, and separated from them by 

 a clear space. 



Head as wide as the mesothorax ; the front and vertex 

 coarsely punctured, sparsely covered with short, fuscous 

 hair ; the centre below the antennae shining, its middle 

 almost impunctate ; the base and apex with large, deep, 

 widely separated punctures ; the part next the eyes 

 closely rugosely punctured, almost longitudinally striated. 

 Clypeus with large, deep punctures, except near the eyes, 

 where the punctures are smaller and closer. Labrum 

 fringed with long, fulvous hair. Mandibles black, piceous 

 at the apex ; the base opaque, finely striated ; with one 

 large apical, and a smaller subapical tooth. Scape of 

 antennae fringed with longish pale hair above ; the 

 flagellum brownish beneath towards the apex. Pro- and 

 meso-notum and scutellum shining, smooth ; the meso- 

 notum with three shallow furrows in front ; the apex of 

 the scutellum with a row of shallow, large, round 

 punctures ; the post-scutellum covered with white 

 pubescence. Median segment with an oblique slope at 

 the apex ; without any basal area, but with a faint indi- 

 cation of two converging furrows. The mesopleurae 

 coarsely punctured at the base ; the apex with a broad 

 clearly defined space, broad at the top, gradually narrowed 

 to the bottom, and bearing stout, longitudinal, distinctly 

 separated keels. Metapleurae shining, uniformly marked 

 with shallow punctures and with a broad, shallow furrow 

 at the base. Wings hyaline, the costa, stigma and nervures 

 testaceous ; the second cubital cellule is of nearly equal 

 width, and scarcely one-half the length of the top of the 

 third cellule ; the first recurrent nervure is interstitial ; the 

 second received at the end of the second cellule, the trans- 

 verse cubital nervure turning up sharply (jbliqucly from it.
