The characters of this subfamily have already been fully detailed 

 {ante, p. 176). It is principally distinguished from the Dictyo- 

 jpharinoi by the position of the ocelli, of which there are usually 

 three, and one of them placed on the apex of the face ; this facial 

 ocellus is stated by Stal to be very rarely wanting, and if wanting 

 the sides of the clypeus are convex and not carioate. From the 

 subfamilies which immediately follow it, it is to be at once dis- 

 tinguished by the length of the claval vein, which does not reach 

 the apex.
