38 Cameron, Hyuunoptera Orientnna. 



A larger species than C. metallicits ; ma\- easih' be 

 known from it b}' the median segment being closel)' 

 reticulated, not transversely striated, by the darker 

 coloured wings with black nervures, and by the distinct 

 projecting keel on the middle of the metanotum. 



CnemocrvI'TUS, gen. 710V. 



Has the median segment areolated, as in the Heviitelina 

 and Phygadneuonina. From the former it may be known 

 by the second transverse cubital nervure being distinct, by 

 the antennae being larger and not so stout towards the 

 apex, and the areolet larger and more distinctl}^ square in 

 shape ; from the PhygadnenoniJia b\' the longer and more 

 slender antennae, by the larger square areolet, which 

 receives the recurrent nervure before the middle, and by 

 the spiracles on the petiole being received nearer the 

 middle. 



Antennae as long as the bod}-, thickened towards the 

 apex ; the basal joints of the flagellum elongate, clypeus 

 large, deeply foveate laterally above, where it is separated 

 from the face by a suture. Mandibles bidentate. Occiput 

 margined. Parapsidal furrows distinct at the base. 

 Median segment completely areolated ; the spiracles 

 small, oval. Areolet square, large ; not narrowed above ; 

 the recurrent nervure received shortly before the middle ; 

 the transverse median nervure interstitial ; the cubital 

 nervures in the hind wings pellucid. Legs stout, the 

 hinder tarsi annulated with white. Petiole longer than 

 the second segment, not much dilated towards the apex ; 

 the spiracles placed shortly beyond the middle ; the 

 apical segment white above ; the ovipositor exserted.
