HYMENOPTERA FROM SARAWAK. 47 



apex ; the eyes are Urge, parallel ; the malar space is small ; the 

 spiracular area is obsolete ; below the spiracles, in the middle 

 of the metapleura}, is a curved longitudinal keel, which originates 

 shortly behind the middle, but not extending to the base ; there 

 are two transverse lines on the base of the median segment ; 

 the bases of the tibite are black. The basal segment is 

 longer than the width of its apex ; the other segments 

 are all wider than long ; the transverse and oblique furrows are 

 distinct; the head is only very slightly developed behind the 

 eyes. 



Comes nearest perhaps to X, punctata. Fah. The edge of 

 the pronotum is more sharply raised than usual ; the base of the 

 middle lobe of the mesonotum more distinctly separated, and 

 the labium more projecting and sharper pointed,

Hab. Borneo (Shelford). 



This species forms a section with three large arete on the 

 median segment and only one apical. 



Antennae brownish on the under side ; the scape yellow 

 beneath; head luteous; the ocellar region and the greater part 

 of the occiput black. Face sparsely punctured, slightly keeled 

 down the middle. Clypeus smooth and shining, its apex broadly 

 rounded. Mandibles black at the apex. Mesonotum smooth and 

 shining, base covered with a short pile, black; the sides and two 

 lines in the middle, extending from the base to near the apex, 

 bright yellow. Scutellum thickly covered with long black 

 hair; its apex, from shortly behind the middle, black. The base 

 of the median segment between the stigmas and to near the 

 apex of the arete is black; the central area is nearly square; the 

 lateral are longer and narrowed towards the apex and are long- 

 er on the outer than on the inner side, the apex being oblique. 

 The apex of the propleurte, the base of the meso-, the top below 

 the tubercles and the apex except a large spot above, and the 

 basal half of the metapleura±, are black. Legs coloured like
