 joints 3 and 4 annular, joint 5 the longest, the remainder 

 cylindrical, hardly longer than broad in the middle, and 

 gradually tapering and lengthening towards the extremity, 

 the last conical ; tips of mandibles black ; ocelli very large, 

 filling up the space between the eyes on the vertex, black, 

 except extreme front of the frontal ocellus beneath, and the 

 outer sides of the two hinder ocelli. Thorax and abdomen 

 very finely and closely punctured ; mesothorax with two 

 converging lines slightly yellower than the ground-colour, 

 but only carinated at the lateral borders ; metathorax also 

 with a middle carina. Abdomen very large, raised, and 

 somewhat compressed laterally. Hind legs longer than the 

 others ; all the tibise armed with a pair of terminal spines. 

 Wings rather broad, yellowish hyaline, more strongly tinged 

 with yellow at the base and along the costal area of the hind 

 wings, and towards the tip a little smoky, especially on the 

 hind wings. Nervures rufous along the costa and towards 

 the inner margin ; otherwise blackish. Anterior wings with 

 3 bullae — one on the lower curve of the cell near its extremity, 

 one on the recurrent nervule, and the third on the cross-
