* Tregret that I did not receive Mr. Haliday’s talented ‘ Hymenopterorum 
Synopsis,’ until too late to make use of it in my text; I have however added his 
groups in this Synopsis, as synonyms, rather than entirely omit them. His primary 
divisions of the order are Sessiliventres and Petioliventres, which the identical struc- 
ture of the ovipositor of Urocerus and Ichneumon appears to me to oppose.
