epinotum narrow and compressed. The dorsum of the epinotum 

 flat, with slightly raised lateral margins which end just before the 

 apex in two short teeth which are continuous with the sharply raised 

 lateral margins of the declivity (see Pig. 3, p. 4). Petiole convex 

 anteriorly, sharply truncate and slightly concave posteriorly, com- 

 pressed laterally so as to form an acute dorsal ridge which ends 

 posteriorly in a curved point, with a small notch at its base. - The 

 posterior apex of the petiole lies considerably higher than the thorax. 

 Ventral lamella produced along nearly its whole length into a 

 blade-like expansion which is truncate in front and semicircularly 

 emarginate behind. 



x\bdomen pear-shaped ; 1st segment nearly as long as the 2nd, 

 the latter as long as the remaining segments together. The apical 

 segment is microscopically rugulose and with a sparse but coarse 

 piligerous puncturation. 



The legs are long, the posterior metatarsi as long as the tibiae. 



? . Unknown. 



3 . 18 mm. Testaceous, scutellum and last two abdominal seg- 

 ments darker. Head, between the eyes and ocelli and posteriorly, 

 black and shining. Wings pale fuscous, nervures and stigma 

 piceous. Head strongly transverse. Eyes and ocelli very large, the 

 former occupying almost the whole of the sides of the head. 



Clypeus trapezoid, arcuately emarginate in front, and separated 

 from the frontal area behind by a suture. The frontal area is large 

 and projects back in an acute angle between the antennal sockets. 

 Frontal carinae rudimentary. Antennae filiform and very long, 

 reaching back to the apex of the 4th abdominal segment ; the 

 scape very short, about as long as the long diameter of the 

 ocellus. 



The mesonotum is dull and finely punctured, rounded, and with a 

 shallow furrow on each side which extends from the posterior margin 

 to a point beyond the anterior edge of the tegulae. A feeble ridge 

 in the centre extends from the pro-mesonotal suture to about the 

 middle of the mesonotum. Scutellum raised above the level of the 

 rest of the notum ; it is sloping in front and behind, somewhat 

 compressed laterally and separated from the mesonotum by a deep 

 and clathrate suture. 



Epinotum with a faint median sulcus at its extreme base ; the 

 declivity is not steep, but forms a continuous curve with the dorsum 

 and its lateral margins are defined by rather feeble ridges which 

 converge towards the base and almost meet below the median 

 sulcus. The declivity smooth and shining below, the rest of the
