Total length, 16 mm. ; wing, 14 mm. 



In this species the clypeus is terminated by a little margin, 

 truncate, with the angles rather salient, but there is somewhat 

 higher, a sort of depression imitating a fase truncature, forming 

 also on each side a little tooth-like eminence. The thorax is 

 wide, depressed, very large if compared to the slender abdomen. 

 Its upper surface forms a sort of flattened vault, without gibbo- 

 sities; the scutel and post-scutel are flattened, making the con- 

 tinuation of this vault with the upper face of metathorax, which 

 is nol to be distinguished from the posterior face. The latter is 

 canaliculate with a sort of square notch, bordered with sharp 

 ridges. 



The body is not velvety, but much polished, although garnished 

 with fulvous hair. (Type of Spinolse.)
