io6 Cameron, Hymcnoptera Oricntalia. 



the recurrent nervure is received in front of the transverse 

 cubital, ahuost touchinc^ it ; its upper half is broadly 

 curved, its lower straii,dit, oblique ; the curved part is 

 broadly bullated at the top and bottom ; the second trans- 

 verse cubital nervure is largely bullated at the bottom ; 

 the transverse median nervure is received in front of the 

 transverse median, not touching it. The petiole becomes 

 gradually dilated from the base to the apex; the base has 

 a semicircular depression, inside of which are a few 

 longitudinal striations ; beyond this is a shallow, strongly 

 aciculated depression which becomes gradually narrowed 

 to the apex ; the second segment is distinctly furrowed on 

 the basal half at the sides; the gastrocceli rufous, shallow, 

 finely striated. 



AITIIRIS, ^^;/. nov. 



Head buccate. E}-es large, not converging below ; 

 reaching near to, but still distant from, the base of the 

 mandibles ; above, on the inner side, there is a distinct 

 rounded incision. The clypeus not defined from the face; 

 the mandibles have two stout apical teeth. I^ehind, the 

 head is not much developed and is obliquely narrowed ; the 

 occiput immarginate. Scutellum flat ; the sides stoutly 

 keeled to shortly beyond the middle; there are two foveae 

 at the base of the post-scutellum. Aletathoracic spiracles 

 large, linear ; outside them is a stout, obliquely bent keel. 

 Legs stout, the femora thickened ; the calcaria short and 

 thick ; the last joint of the hinder tarsi as long as the 

 preceding three joints united ; the claws stout, simple ; 

 there are two spurs on the hinder tibiae. Wings without 

 an areolet ; the first abscissa of the radial nervure straight, 

 oblique ; the second curved upwards at the base ; the 

 recurrent ncr\-ure is curved and is almost interstitial with 

 the transverse cubital ; the transverse median nervure is
