8 Horizontal part of tergite 1 almost smooth, with faint, satin-like sheen and at most 



with fine, widely scattered punctures on its horizontal part ; ovipositor short, 

 hardly two thirds as long as the hind tibia.

- Horizontal part of tergite 1 with large, well separated punctures over most of its 



surface ; towards posterior corners, the outline of the punctures is obscured by 

 striate-rugosity ; ovipositor considerably longer, fully as long as the hind tibia. 



The yellow and black areas more sharply contrasted than in moscus ; propodeum 

 intensely black ; antenna relatively longer than in moscus ; mesosternum reddish- 

 yellow in type, darker in front and with a dark streak along each side ; mesosternum
