136 HYMENOPTERA FROM SARAWAK. 



defined ; there is a stout longitudinal keel and two less distinct 

 oblique ones on either side of it. Wings hyaline, the radial 

 cellule and the greater part of the apical cubital cellule, smoky ; 

 the petiolated cellule is about one half the length of the fol- 

 lowing 1 ; it receives the recurrent nervure distinctly behind het 

 middle. The four anterior tibia 1 and tarsi are yellow ; the 

 mid tibia are marked behind with black ; the hinder are black, 

 except for a yellow band near their base and the metatarsus. 

 Abdomen closely and coarsely punctured ; black, the apex of the 

 third and of the sixth segment banded with yellow ; the pygidiuin 

 is broad, coarsely punctured; its apex transverse, depressed, 

 membranous, except at the sides ; the epipygium is depressed. 

 The third ventral segment is banded broadly with yellow in the 

 middle. 



A distinct species, not very nearly related to any of the des- 

 cribed Indian species. Characteristic is the " enclosed space" at 

 the base of the median segment which is less clearly bounded 

 than usual and is longitudinally and obliquely coarsely striated 

 and the excavated middle of the median segment.

Sculia pulchriuestita, sp. nov. 



Black ; the head and thorax densely covered with fulvous hair 

 and with a dense golden pile ; the basal segments of the 

 abdomen with blue and purple tints ; the segments edged with 

 pale fulvous hair; the wings fulvous-hyaline: the fulvous tint 

 deeper along the apex; the stigma and nervures deep 

 fulvous. 9 •

Hab. Borneo. 



Antenna black, the scape covered with pale fulvous hair. 

 The vertex behind and in the centre is strongly and closely 

 punctured, and there are a few punctures on the outside of the 

 ocelli ; the upper part of the vertex is smooth, bare and furrowed 

 in the middle : the lower part is punctured and thickly covered 

 with fulvous hair. The clypeus is smooth, base, subtriangular 

 and Hat ; its apex is Hat, broadly rounded and piceous ; the apex 

 of the mandibles broadly rufous. Thorax densely covered, 

 except ou the apical slope of the median segment, with pale
