ICHNBUMONID.B FROM BORNEO. 171 



sides above ; spiracles large, linear. Abdominal petiole stout, be- 

 coming gradually slightly wider towards the apex, where it is twice 

 the width of the base ; the post-petiole not separated ; the spiracles 

 placed close to the middle ; those on second placed at the apex of the 

 bssal third. Clypeus clearly separated, its apex in the middle with 

 two short rounded teeth ; the sides with a hollowed rounded dilatation. 

 Fore tibias thickened, narrowed at the base ; basal joint of tarsi longer 

 than all the rest united. 



This genus, like Echthrus, Torbda, &c, is intermediate 

 between the Cryptinse and the Pimplinas ; from the position of 

 the spiracles on the abdominal segments, they may be placed in 

 the Xoridini. The mesopleuras, as in the Cryptinas, are bordered 

 by a furrow ; and, as in that group, there are parapsidal furrows. 

 Its affinities are clearly with Torbda, Cam., from which it may 

 be known (the coloration being also very different) by the bi- 

 dentate apex of clypeus, smaller square areolet, tuberculate apex 

 of metanotum, and longer metatarsus. Echthrus and Nyxeo- 

 philus are placed by some authors in the CryptinaD ; by others in 

 the Piuiplinae ; probably there will be also a difference of opinion 

 as to the position of Dinocryptus and Torbda. 



DlNOCRYPTUS NIGER, Sp. DOV. 



Black ; thorax, base of abdomen and of legs thickly covered with 

 short black pubescence ; wings uniformly fuscous violaceous. ? . 

 Length, 21 mm. ; ovipositor, 10 mm. 



Kuching. April (R. Shelford, M.A.). 



The entire body is closely punctured. Basal part of metanotum 

 slightly carinate in the middle, and slightly depressed on either side of 

 the centre. There is a pale white line in the centre of the orbits on the 

 outer and inner. The second to fifth abdominal segments have trans- 

 verse impressions near the middle. The last segment is large, depressed 

 at the base ; the apex is depressed above, and is thickly covered with 

 long black hair. Antennas long, slender, the basal two joints of 

 flagellum equal in length. 



XORIDINI. 



Co3nostoma, gen. nov. 



c? . Upper part of clypeus short, obliquely projecting ; the lower 

 part longer, not obliquely projecting, obliquely narrowed, the apex 

 transverse. Labrum large, semicircular, fringed with long hair. 

 Mandibles edentate, broad at the base, narrowed towards the apex. 

 Malar space furrowed, as long as the antennal scape. A furrowed 

 keel between the antennas. Head cubital, temples broad, occiput 

 transverse, margined. Thorax four times longer than wide, largely 

 developed before the wings ; mesonoturn 3-lobate. Scutellum flat, 

 two large deep foveas at its base. Post-scutellum stoutly keeled on 

 the sides. Metanotum longer than broad, flat, with the apex rounded, 

 longitudinally reticulated ; the spiracles longish oval. Wings without 

 an areolet, the recurrent nervure received beyond the transverse
