DESCRIPTIONS OF THREE UNDESCRIBED GENERA 

 OF ICHNEUMONID.E FROM BORNEO. 



By p. Cameron. 



ACCENITINI. 



Phalega, gen. nov. 



Wings without an areolet; second recurrent nervure received behind 

 the transverse cubitus, widely distant from it ; disco-cubital nervure 

 broken by a stump of a nervure, transverse median nervure received 

 beyond transverse basal ; transverse median nervure in hind wings 

 broken at the middle. "Wings longer tlian the body. Basal joint 

 of hind tarsi fully longer than the following two united. Parapsidal 

 furrows deep ; the mesonotum clearly trilobate. Metanotum with a 

 keel above the apical slope. Petiole stout, three times longer than 

 wide, clearly separated from the second; ovipositor not much longer 

 than the abdomen. Four front claws cleft. The second abdominal 

 segment is wider than long ; the hypopygium in the female does not 

 project beyond the tip of the abdomen. Head not much wider than 

 the thorax ; apex of clypeus with a small but distinct tubercle in the 

 middle of the apex. Hind coxfe short, about twice longer than wide. 

 Colour uniformly rufous. First joint of flagellum nearly as long as 

 the following two united. 



Comes closest to Collyria and Chorhchizus. 



Phalega lutea, sp. iiov. 



Rufous-luteous, the flagellum of antennae and apex of tibiae fuscous ; 



the hind tarsi black. Wings bright luteous hyaline, the apex of the 



fore wings behind and of the hind pair all round, smoky; the nervures 



and stigma bright luteous. ? . Length, 12 mm. ; ovipositor, 6 mm. 



Matang. August (R. Sbelford, M.A.). 



Face and clypeus strongly and closely punctured ; the face roundly 

 projecting in the middle ; the clypeus with a tubercle on either side 

 above. Vertex almost smooth. Front deeply excavated in the middle, 

 its centre with a distinct longitudinal keel ; the sides punctured. 

 Thorax closely punctured, smooth on the apex of the mesopleurse 

 and on the base of metapleurae. Base and apex of metanotum smooth; 

 the middle punctured and with some strife. Abdomen smooth. Re- 

 current nervure distant from the transverse cubital by three-fourths of 

 the length of the latter ; its front half roundly curved. Hind legs very 

 long ; the femora not greatly thickened, but still clearly thicker than 

 the much longer tibi*. 



DiNocRYPTUS, gen. nov. 

 Areolet large, square, not narrowed in front ; transverse median 

 nervure almost interstitial ; disco-cubital nervure not broken, the 

 radial cellule elongate ; transverse median nervure in hind wings 

 broken below the middle. Wings uniformly fuscous violaceous. 

 Median segment without keels ; the apical slope tuberculate on the
