344: Mr. R. E. Turner 07i Fossorial TJymenoptera, 



Aslimead places this genus in his Pisoninoe together witli 

 his genus Fseuduhelioryetes, which 1 treat as a synonym ot" 

 Paranysson. But I consider the entire eyes and incised 

 mandibles remove it from that group, though the genus is 

 the most isolated of the present subfamily, and some doubt 

 as to the correct position is justifiable. The incised man- 

 dibles and single spur of the intermediate tibise remove it 

 from the Nyssoninse. The mandibles of S. rubricatus, the 

 only species in which I have been able to study the inner 

 margin^ have two small teeth near the base, as in the other 

 genera of the subfamily. This points to the correctness of 

 Kohl's views as to the relationship of tlie genus.
