seen in lateral aspect. Ovipositor stout, curving upward, issuing from the 

 tip of the abdomen, but visible as an impression in the specimen to the base of 

 the abdomen where it curves upward to the middle of the basal part of the 

 abdomen. Wings and legs not preserved.

This may be a Palaeotorymus but its large size and stout habitus 

 recall so strongly the North American T. magnificus O. S. that I have 

 ventured in the absence of the wing to place it in the recent genus. 



Palaeotorymus, gen. nov. 



General habitus like that of Torymus and its allies, but easily distinguishable 

 by the immensely elongated postmarginal vein which extends nearly to the 

 apex of the wing. In recent Torymidae the postmarginal vein is generally 

 distinctly developed, but in no case does it approach this extraordinary length.
