 strongly gibbous, obsoletely punctured, pilose ; post- 

 scutellum impunctate, the space between the 

 scutellums reticulated. Metathorax very strongly 

 reticulated, gibbose, the centre excavated; there 

 are only four median areae, the superniedian being 

 absent ; the posteromedian very strongly reticulated ;. 

 at its base is a small, shining, impunctate space ; the- 

 metapleurae are less strongly reticulated than the 

 rest of the metathorax. The prosternum is covered 

 with long yellowish hair, the mesothorax closely 

 pilose ; metathorax with the hair longer, but more^ 

 irregularly distributed. Petiole finely punctured,
