HYMENOPTERA OF SARAWAK. 113 



the apex of scutellum bordered by a stout keel ; the scutellum 

 is more strongly punctured than the mesonotum. Post-scu- 

 tellum stoutly keeled laterally, the united keels produced behind. 

 Areola longer than it is wide at the apex, which is tranverse, 

 the base is narrowed obliquely to a sharp point ; this is bor- 

 dered at the base by a triangular area, the apex being shortly 

 beyond the middle of the areola ; a keel runs from its 

 base to the top of the apical slope which is bordered 

 by a stout keel; the areola thus formed is four-angled, 

 the base being long and sharp-pointed ; the spiracular 

 area is large ; on the apical slope is a large central with an 

 irregular keel in its middle and a smaller square area. Below 

 the middle of the mesopleurae, on the apical half, is an oblique 

 - furrow, which encloses with the lower wider crenulated one a 

 triangular area. The keel bordering the sides of the metanotum 

 is twice roundly dilated at the base, the basal being the longer, 

 below these at the apex is a small and a large bluntly 

 rounded tooth. Abdomen smooth ; the basal segment is more 

 than twice longer than it is wide at the apex, it is as long as 

 the following 2 segments united. The malar space is half the 

 length of the eyes. Areolet narrowed in front, the nervures 

 touching there ; the outer one is obliquely sloped towards the 

 cubitus, the lower, and much smaller part, is sloped towards 

 the base of the cellule. 



Cremnops borneana, sp. nov. 



Luteous, a broad band across the ocelli, the antennae, apex 

 of the hind tibiae and the hind tarsi, black ; wings fuscous ; the 

 base of the stigma and the nervure yellow ; the base to the 

 transverse median nervure and to near the lower part of the 

 transverse basal yellowish hyaline ; a hyaline cloud fills the 

 1st cubital cellule and extends across to the base of the anal 

 nervure. 9 . 



Length 7 mm. ; terebra 4 mm. 



Kuching. October. 



Head and thorax closely covered with short white pubes- 

 cence. Palpi coloured like the head. Malar space as long as the 

 eyes. Thorax closely covered with short pale pubescence;
