 BANCHI. 

 Baliena, gen. nov. 



Arcolct small, oblique, the transverse cubital nervurcs 

 touchin;^ above ; the lower side angled ; the apical abscissa 

 of the radius is curved upwards. Eyes larger than usual ; 

 distinctly converging beneath, reaching close to the base 

 of the mandibles. Cl}^peus small, twice as broad as long; 

 its apex semicircularly depressed. Mandibles broad at 

 the base, narrowed at the apex, which has one tooth. 

 Face roundly convex, reaching near to the lower side of 

 the e}'es. Occiput immarginate. Mesonotum trilobate ; 

 the middle lobe triangular at the apex. Scutellum large, 

 flat. INIedian segment elongate, nearly as long as the 

 mesothorax ; it has a gradual slope to the apex, has the 

 small, somewhat oval, spiracles in the middle, has no keels, 

 and is closeh^, but not strongh', reticulated. Legs long, 

 slender ; the hinder coxa; large, as long as the petiole, 

 which becomes gradually wider towards the apex ; the 

 spiracles on the petiole are circular and are situated 

 shortly before the middle ; the apex of the petiole is not 

 curved. Claws bifid. Ovipositor longer than the 

 abdomen, and issuing from a ventral cleft. 



The abscissa of the radius is curved upwards at the 

 base ; the transverse basal nervure is interstitial ; the 

 recurrent nervure is received at the base of the apical 

 third ; the second transverse cubital nervure is faint ; the 

 recurrent nervure is largely bullated in the middle ; the 

 sub-discoidal nervure issues from the middle. 



Comes near to Banchns and Exetastes ; the former 

 may be known from it by the pectinated claws : the latter 

 by the different form of the face and clypeus ; by the 

 metathoracic spiracles being placed behind the middle ; 

 and bv the shorter legs.
