Size of X. fasciatum, with which it agrees in coloration 

 throughout, except that the wings are a little darker, the 

 dorsal band is a little broader, and the ovipositor is of a 

 reddish brown throughout, while in X. fasciatum it is green 

 at the base ; wings .08 in. shorter than the wing-covers ; 

 both shorter than the body ; ovipositor nearly equalling 

 the hind femora in length. In these respects it differs very 

 much from X. fasciatum. 



Length of body, .5 inch ; of wing-covers, .33 in. ; of hind 

 femora, .43 in. ; of ovipositor, .4 in.
