104 HVMENOPTERA OF SARAWAK. 



tudinal striae. Median segment coarsely reticulated ; the reti- 

 culations on the lower part of the pleurae are longish, regular and 

 oblique ; above, the striae form shorter, more rounded reti- 

 culations. Coxae stoutly, irregularly striated; the hind femora 

 are finely, closely punctured, almost striated, the claws with 

 4 teeth besides the apical one. Transverse median nervure 

 interstitial or almost so, it touching the hinder edge of the 

 transverse basal. 



Apart from the differences in coloration this species 

 differs from the other Sarawak species — P. erythrocephalus 

 Cam. in the pronotum being toothed. It belongs to Deraio- 

 dontus Bradley (which, however, appears to be identical with 

 Pristaulacus Kieff. sensu sir.) except that it has 4, instead of 

 2 teeth on the pronotum.

 the centre and sides of median segment, the abdomen and the 

 hinder legs, black ; the ventral surface white, with large black 

 marks on the sides ; wings to the transverse basal and median 

 nervures yellowish hyaline, fuscous beyond ; the stigma black,
