HYMENOPTKRA FROM SARAWAK. 41 



sparsely punctured. Mandibles black, broadly rufous at the 

 base ; the palpi rufo-testaceous. Thorax smooth and shining- 

 rufous ; the median segment black. The anterior legs rufous ; 

 the posterior four black ; the middle trochanters rufous. Wings 

 brownish-smoky, with a slight violaceous tinge at the base; the 

 stigma and basal nervures black ; the apical nervures fuscous. 

 The sides and ventral surface of the petiole are pale testaceous ; 

 its base is smooth ; the rest of it coarsely reticulated. The 

 second and third segments are closely, irregularly longitudinally 

 punctured, at the apex almost reticulated; the fourth is closely 

 reticulated, the centre more strongly than the sides ; the other 

 segments are smooth. The keel on the base of the second 

 segment is not very distinctly defined ; it is broad at the base, 

 becomes gradually obliquely narrowed towards the apex, is 

 more strongly striated than the rest of the segments and 

 reaches to shortly beyond its middle; the lateral furrows are 

 wide, oblique and stoutly striated ; the lateral furrows on the 

 third and fourth segments are narrower and more roundly 

 curved ; the transverse furrows on the base and apex of the 

 third and fourth segments are closely longitudinally striated. 



Ilolcotroticus, gen. nov. 



Claws of all the legs bifid ; the inner claw smaller than the 

 other. Median segment completely areolated. Apex of the 

 scutellum bifurcate, bordered by stout keels-; the apex of the median 

 segment obliquely depressed. Malar space moderately large, the 

 oral region not greatly lengthened. Wings longer than the body ; 

 the areolet narrowed at the top ; the nervures without a stump of 

 a nervure. The oblique mesopleurse furrow is wide and deep; a 

 narrow oblique one runs from its middle. Pro- and mesopleurte 

 above with an oblique keel; between the tops of the middle and 

 hinder coxae is a stout keel. The fore tarsi are longer than the 

 tibiae; all the joints are longer than broad; the middle three are 

 much shorter than the others. The hinder legs are much longer 

 than the others ; their coxae are large, more than twice longer 

 than wide. The joints of the maxillary palpi are elongated, 

 the three penultimate joints are not short, compressed or lenticu- 

 lar. The occiput is margined, the sides more distinctly than the 

 upper part; the two hinder ocelli are flat, not convex; there is a
