170 Cameron, Hymenoptera Orientalia. 



transverse band, incised in the middle at the apex ; the 

 oblique furrows on the last segment, narrow, deep and 

 distinct. 



The following species is probably related to the fore- 

 going group. The colour of the abdomen and legs is 

 doubtful, as the ferruginous tint of the abdomen and legs 

 may be caused by chemical discoloration ; but structurally 

 it is distinct from any of the yellow species. The scutellum 

 is more distinctly keeled at the apex than in the yellow 

 species, the apical and the lateral keels being continuous.
