126 HYMENOPTERA OF SARAWAK. 



joints united; claws small. Antennae filiform, bare, longer 

 than the body, the 3rd and 4th joints equal in length ; the 

 scape globular, not much longer than broad. Disco-cubitus 

 not broken by a nervure. 



I only know the $ of this genus of Xorides. The front 

 tibiae are not inflated as in manj of the genera of the group. Its 

 affinities are clearly with Spiloxorides ; but that genus has the 

 median segment areolated, not reticulated, much shorter and 

 not tuberculate laterally at the apex, its hinder coxae much 

 shorter and the basal joint of the hinder tarsi is shorter than 

 the other joints united, being not much longer than the 2nd and 

 3rd united. 



Ccsnostoma filicorms, sp. nov. 



Black, labrum, clypeus, orbits broadly, the edge of theprono- 

 tum, scutellum, the 4 front legs, the basal two- thirds of the 

 hinder tibiae and tte hinder tarsi, yellow ; the hinder coxae and 

 femora rufo -testaceous ; the extreme base of the hinder coxae, 

 their apical third, trochanters, base of tibiae narrowly and their 

 apical fourth, black ; the apices of all the abdominal segments 

 banded with yellow ; wings hyaline, the nervures and stigma 

 black, the base of latter white. 5 •

 basal foveae large vnder than long ; post-scutellum with 2 

 longer than wide foveae. The reticulations irregular, much 

 longer than wide. Propleurae smooth, the meso- shagreened 

 and thickly haired, the meta- ! closely reticulated. Base of 

 petiole smooth ; in the centre are 2 narrow keels with a keel 

 on either side, the rest closely, irregulary reticulated ; the 2nd

 sions closely striated ; there is a curved furrow. On the apex
