Description of New Species of 

 Hymenoptera from Borneo. 



A — On some new species of Iphiauhx ( Braconidae) 

 from Kuching, Borneo. 



By P. Cameron. 



I am indebted to Mr. John Hewitt, the Curator of the 

 Sarawak Museum, for the opportunity of describing the fol= 

 lowing species of Iphiauhx which appears to be the most 

 abundant genus of Hymenoptera in Malaya, so far as the 

 number of species is concerned. 



The species may be most conveniently grouped by the 

 form of the plate on the base of the 2nd abdominal segment. 



i. The plate large, triangular, striated, bordered by 

 oblique striae. Ins ignis, Sm., cariniceps, Cam., 

 octofoveatus, Cam. In this group the 1st abdomi- 

 nal segment is closely longitudinally striated, and 

 the metanotum is more or less black. 



ii. The plate minute smooth, followed by a keel which 

 extends to the apex of the segment ; the central 

 part bordered by keels ; the 1st segment keeled 

 laterally and down the centre. Alienatus, Cam. 



hi. The plate moderately wide at the base, becoming 

 gradually narrowed to a fine point, then continued 

 as a keel to the apex of the segment. In this 

 group the striation does not extend beyond the 

 middle of the 3rd segment, the following segments 

 being smooth. There is a distinct keel down the 

 middle of the 1st abdominal segment and a less 

 distinct one along the sides. Extrancus, Cam. 

 enrythecus, Cam., and declinatus, Cam,
