8 HYMENOPTERA FROM BORNEO. 



divided at the sides, which, at the furrow, are reticulated ; there 

 are no transverse furrows on the apex of the segments ; there 

 is a narrow crenulated furrow on the base of the 4th segment. 

 The raised centre of the 1st abdominal segment is keeled down 

 the sides and down the middle ; on the sides are 3 or 4 irregular 

 foveae ; the wide lateral furrows are irregularly transversely 

 striated. Malar space nearly as long as the antennal scape, 

 more than one third of the length of the eyes. Centre of 

 face base, smooth, the sides sparsely haired. Temples as 

 long as the top of the eyes, rounded, but hardly narrowed ; 

 the occiput rounded inwardly. Metapleural furrow distinct, 

 continuous. On the centre of the apex of the metanotum are 

 3 stout keels, bordered at the end by a stouter transverse one. 

 Front distinctly broadly depressed in the centre ; there is a 

 furrow down the middle. Tibiae and tarsi densely covered 

 with black stiff hair. The apical wing nervures are fuscous. 6 



Length 9-10 mm.

Black, the head, thorax and fore legs red, the middle legs 

 of a darker red, their tarsi fuscous wings fuscous, the nervures 

 and stigma black ; the 2nd, 3rd and entirely the 4th abdonimal 

 segment to shortly beyond the middle closely, strongly longi- 

 tudinally striated ; the area on 2nd segment reaching to the 

 apex, becoming gradually • narrowed to a sharp point ; some- 

 what strongly longitudinally striated ; the raised central part of 

 the 1st segment broadly furrowed down the middle, the furrow 

 narrower than the sides, which are irregularly longitudinally 

 stoutly striated, almost reticulated. Apical slope of metano- 

 tum stoutly longitudinally striated, the centre at the base 

 raised, the raised part smooth at the base, the apex with a 

 twisted keel. Sheaths of ovipositor broadly white at apex. 9 . 



Length 13 mm., terebra 20 mm.
