HYMENOPTERA FROM SARAWAK. 43 



large spiracular area. The two front legs are of a paler rufous 

 colour than the thorax; the middle pair have a piceous hue. 

 The wings are of a uniform dark fuscous-violaceous colour, 

 with black nervures and stigma. Abdomen deep black, smooth 

 and shining ; the petiole is furrowed along the sides. 



The malar space is not quite so long as in typical Agathhlini, 

 the head not being so rostriform as usual. It differs also from 

 Agathis in the hinder claws having a tooth near the base. 



ICHNETJMONID/E. 



Siphimedia, gen. nov. 



Wings without an areolet; the recurrent nervure intersti- 

 tial, or almost touching the transverse cubital; the transverse 

 basal nervure interstitial ; the transverse median nervure in hind 

 wings broken shortly above the middle. Mesonotum trilobate ; 

 the middle lobe transverse at the base, sharply pointed at the 

 apex; the parapsidal furrows deep. Post-scutellum deeply 

 bifoveate at the base. Median segment areolated more or less 

 with three or four basal area? ; the areola distinct ; the spiracles 

 are linear, longish and are placed in the middle. Legs, and 

 especially the posterior, stout; the hinder femora thickened/ 

 shorter than the tibia? ; the four front claws are cleft, the hinder 

 simple; the hind coxae are twice as long as thick, the basal joint 

 only as long as the following three united and not much longer 

 than the apical. The antenna? stout, shorter than the body. 

 The petiole is twice longer than the width at the apex ; it is 

 broad at the base and becomes gradually wider towards the 

 apex; the spiracles are placed shortly behind the middle; the 

 abdominal segments are smooth, without furrows or depressions ; 

 the second and following segment's are wider than long; the 

 hypopygium is very large, plough-share-shaped and projects 

 beyond the dorsal segment; the ovipositor is stout and is about 

 as long as the body. The front legs have one, the four hinder 

 two, spurs. There is a curved furrow on the sides of the meso- 

 sternum. 



The antenna? are placed well up on the face, above the 

 middle of the eyes, which are parallel; the apex of the clypeus 

 is rounded ; the mandibles have two subequal teeth ; the cly peu
