HYMENOPTERA OE SARAWAK. . 103 



the mesonotum ; in C. ruficeps it is slightly raised ; the parapsi- 

 dal furrows are absent. C. lutea may belong to Platybracon, 

 Szep. 



Lissobracon, gen. nov. 



Head cubital ; temples broad ; occiput and cheeks not 

 margined. Apex of clypeus obliquely depressed, rounded. 

 Antennae stout. Three cubital cellules. Radial cellule long, 

 extending to the apex of the wing. Transverse median nervure 

 received beyond the transverse basal. Second discoidal cel- 

 lule closed. Anal nervure not interstitial. Hinder wings as 

 in Bracon, but with the pobrachial and the transverse pobra- 

 chial nervures obsolete. Legs of moderate length. Abdomen 

 smooth and shining, without transverse furrows on any of the 

 segments. 



There is a clear malar space; scape of antenna?, short, 

 thick, not much longer than broad, not much longer than the 

 3rd. Mandibles with a long upper and a shorter and blunter 

 subapical tooth. Mesonotum indistinctly lobed ; the furrows 

 shallow, not clearly defind. Calcaria short. Antennae stout, 

 not narrowed towards the apex. 



This genus has not a semicircular opening between the 

 mouth and the mandibles, it being transverse, not rounded. 

 In other respects it agrees fairly well with the Bmconnea 

 except that the transverse median nervure is not interstitial ; 

 but it does not fit very well in to any of the tribes. The 

 antennae are much stouter than usual. 



Lissobracon forticorniS) sp. nov. 



Black, smooth and shining, the head,, thorax, except the 

 metanotum and the front legs rufous ; antennae stout, black, the 

 scape sparsely haired, the flagellum bare. 9 . 



Length 19; terebra 50 mm. 



Hab. Matang. 



Head sparsely haired ; the metanotum covered with longish 

 black hair ; the femora sparsely, the tibiae and tarsi thickly cover-
