of the mouth- edge. The swollen out genae are carried forward beneath the toruli 

 also, and are largely visible from in front. In the middle of the clypeus is a minute 

 notch flanked on each side by a more or less distinct short lobe or tooth. The toruli 

 are elongate, sub-triangular, broadest ventrally, with their adjacent sides sub-parallel. 



Antennae (fig. 2), 6 (7)- jointed ; scape, pedicel (ring- joint), three in funicle, club 

 solid. Bulla long, apex of pedicel oblique, funicular joints gradually expanded. 

 Second funicular joint set at an angle to the oblique apical dorsal surface of the first ; 

 second and third funicular in the same straight line, but the suture between them 

 is more or less oblique. Third joint with one sensorium ; club wider than last 

 funicular, with several sensoria, and ending in a short outwardly curved beak. On

the inner apical aspect is a small sense-organ consisting of 4-5 sensory hyaline bristles,, 

 stouter than the elements of the general chaetotaxy of the antenna, standing above 

 definite passages through the integument of the club. 



Mouth-parts : Labrum triangular, apically rounded, with 2 central preapical 

 bristles. Mandibles broad basally (8:7), tridentate. Trophi nearly circular ; cardo 

 small and narrow, stipes swollen and broad ; maxillary palpus with the second joint 

 sometimes presenting a false appearance of being divided in two ; labial palpus 

 longer than either joint of the maxillary ; ligula with two median setigerous cells. 



Thorax (fig. 1, a, b, d, e, f) flat dorsally ; including the propodeon, half as long 

 again as broad, widest at the level of the fore wings. The pleurae are very little
