Provespa a New Genus in the Vespidae. 



By William H. Ashmead. 

 In arranging the Vespidce in the National Collection I find 

 quite a large series of Vespa dorylloides Saussure, collected by 

 W. L. Abbott, in Trong, Lower Siam, which I find cannot be 

 placed in Vespa Linne as now restricted, and for which I propose 

 to erect a new genus Provespa, easily separated from Vespa L. 

 by the aid of the following table : 



Third cubital cell along the radius fully as long as the cubitus or a little 

 longer. 

 Ocelli large, rather close together, the lateral almost touching the eye 

 margin, not their width from it ; abdomen rounded at base, 



not truncate Provespa, gen. no v. 



(Type. — Vespa dorylloides Saussure. ) 



Ocelli small, the laterals far from the eye margin, at least thrice their 



width from it ; abdomen truncate at base .... Vespa Linne. 



(Type. — V. vulgaris L.)
