which the hinder almost touch. Mesonotum shining ; 

 the scutellum pallid yellow ; the base of the median 

 segment depressed in the middle; a stout transverse keel 

 behind it ; behind this keel the segment is coarsely 

 shagreened and with an indistinct furrow down the 

 centre ; the pleurae coarsely shagreened. Legs uniformly 

 fulvous, almost bare ; wings clear hyaline ; the stigma 

 fulvous ; the clear bare space contains one large horny 

 mark, with a distinct dark border ; above it is a curved 

 spot, and behind two smaller spots. Abdomen darker 

 towards the apex. The cubital nervure is much thickened 

 at the base. 



Enicospilus, or Henicospilus as the purists would have 

 it, differs from Ophion proper in the fore wings having a 

 clear space, which usually contains one or more horny 

 points ; and, the stump of the cubital nervure, found well 

 developed in Ophion, is absent. In some cases the smooth 

 space is present without having horny points in it, or they 

 are very faint. In either case I believe it will be found 

 that the base of the cubital nervure is thickened, which 

 is not the case with Ophion, sensu sir. In view of the 

 great similarity of the species of Ophion, it seems to me 

 desirable to adopt Enicospilus as a distinct genus. Species 

 belonging to it are found in all parts of the world.
