segment rufo-testaceous ; legs rufo-testaceous, tlie posterior black, 

 the base of middle tibiae, their apex more narrowly, the middle tarsi, 

 basal half of hinder (the basal joint to near the apex), and, to a less 

 extent, the fore tarsi, white. Abdominal petiole about twice longer 

 than the rest of the abdomen. Terebra almost as long as the body. 

 Wings clear hyaline, the nervures and stigma almost white. Cephalic 

 tubercles short, bluntly rounded. Pro- and mesothorax smooth and

 crenulated. Metanotum strongly aciculated. Pleurae smooth. $ . 

 Length, 7 mm. ; terebra 6 mm. 



Outer orbits lined with white. Mandibles pale, black at the 

 apex. Basal joints of palpi black, the rest testaceous. Middle femora 

 of uniform thickness. Pronotum about one-half longer than it is 

 wide at the apex. There are only two teeth on the hind femora, 

 a conical one behind the middle and a small conical one near the 

 base of the apical fourth. 



Megischus ruficollis, sp. n. 

 Black, the head and prothorax red, the face and oral region paler 

 in tint, the outer orbits broadly and the basal half of the mandibles 

 pale yellow ; the basal four or five joints of the antenna3 and the

 darker coloured, the hinder black, the knees rufo-testaceous, the 

 narrowed basal part of the tibiae fuscous, the tarsi white ; there are 

 two large teeth on the femora, one near the apex of the basal third, 

 the other near the base of the apical fourth ; there are two short 

 stumpy teeth at the base, four small, sharper ones between the large 

 ones, the apical more widely separated from the others than these 

 are from each other ; there are three small ones beyond the apical 

 large tooth, the basal longer and sharper than the others and touch- 

 ing the large one, the other two are stumpy, the basal larger than 

 the apical. Wings hyaline, the stigma and nervures fuscous, the 

 base of the stigma paler. $ . Length, 7 mm. 



Kuchiug, Borneo (John Hewitt, B.A.). 



Face shagreened, closely transversely striated, more strongly on 

 the sides ; the vertex is more finely striated. The lower frontal spine

 sparsely so at the apex ; the metapleurai aciculated, the pro- and 

 mesopleurae smooth. Hind femora and abdominal petiole closely 

 transversely striated. Scutellar fovea clearly defined, twice wider 

 than long, of equal width, deep; the base bounded by a narrow 

 smooth keel, the sides by a smooth wide one. Pronotum about one- 

 fourth longer than it is wide at the apex. The cubitus is straight, 

 extends to the apex of the transverse cubitus (which is straight) and 

 forms a sharp angle with it.

Black, the apex of clypeus, its sides more broadly than the centre, 

 the apex of pronotum narrowly, the sides of the propleurie more 

 widely, the mark narrow^ed and rounded at the base, and a large
