112 HYMENOPTERA OF SARAWAK. 



the sternum are crenulated. Metanotum closely reticulated, 

 a keel down its centre ; the metapleurae punctured at the base, 

 irregularly reticulated elsewhere. The basal 4 segments of the 

 abdomen are closely longitudinally striated, the striae becoming 

 gradually weaker ; the base of the 5th segment is weakly 

 punctured ; the apical two are smooth and shining. The basal 

 tooth on the hind coxae is long, curved ; and its apex reaches 

 to the end the coxae ; the lower one is much smaller, hardly 

 one fourth of the length of the upper. The 2nd cubital cellule 

 is clearly longer than wide, its apex being not much more than 

 half its length on the posterior side ; the 2nd transverse cubital 

 nervure is about the length of the 1st abscissa of the radius ; 

 it is shorter than the 1st, the 2nd cellule being thus narrower 

 at the apex than at the base. 



There are 5 short, stout spines on the innerside of the 

 fore tibiae ; the abdomen is broader than the thorax ; it is 

 longish oval and is as long as the head and thorax united ; the 

 ocelli are in a black spot ; a keel runs down from them to the 

 antennae ; the antennae are filiform, much longer than the body. 

 The longitudinal nervure in the hind wings is roundly curved. 



Agathin^e. 

 Disophrys tinctipennis, sp. nov, 



Luteous, the flagellum and the hinder tarsi black ; wings 

 fuscous, the base to the transverse median and to the top of 

 the transverse basal yellowish hyaline, the hinder fuscous, 

 yellowish hyaline at the base. 6 . 



Length 8 mm. 



Kuching. September. 



Flagellum of antennae thickly covered with black, the 

 scape and thorax with fulvous pubescence. Face, clypeus and 

 thorax distinctly, moderately closely punctured. The keel 

 running from the outer ocelli to the antennae is stout ; in the 

 centre is a narrower keel. Middle lobe of mesonotum separat- 

 ed ; in its middle, on the basal slope, is a stout keel, which ends 

 in 2 fine ones. Mesopleurae furrow irregularly crenulated. 

 Scutellar depression large, with 3 stout keels in the middle ;
