136 Cameron, HymenopUra Orientalia. 



Clypeus not separated from the face by a suture. Eyes 

 large, reaching near to the base of the mandibles ; the 

 upper orbits margined. Mesonotum trilobate, reticu- 

 lated in the middle at the apex. Metathorax elongate, 

 with a gradually rounded slope to the apex ; the spiracles 

 placed near the middle, oval. Legs elongate, slender, 

 the hinder tarsi large, elongate, smooth, or striated on 

 the outer side ; the hinder tarsi nearly equal in length 

 to the tibiae ; the claws with a stout basal tooth, shorter 

 than the other, which is curved and thinner; coxae large, 

 elongate. Abdominal segments smooth ; the petiole 

 longer than the second segment, gradually widened towards 

 the apex; the other segments not much broader than 

 their length, smooth ; the gastrocceli distinct ; the ovipositor 

 long, issuing from a ventral cleft. The spiracles are small, 

 oval, almost round, and are placed near the middle of the 

 segment. 



This genus is nearly allied to RJiyssa and Epirhyssa,. 

 which differ from it in the transversely striated mesonotum, 

 in the shorter metathorax, in the mandibles being biden- 

 tate, in the shorter petiole, which has the spiracles placed 

 much nearer the base, and in the longer hinder tarsi, which 

 are distinctly longer than the tibiae. 



A. A reolet absent.
