into an exceptionally prominent liurap, with anterior ocellus 

 facing forwards at summit and the posterior pair evidently 

 flanking the sides. 



Protliorax only about 0*7 the length of the head, transverse, 

 with angles rounded ; widest near posterior angles, where it 

 is twice as wide as long ; surface with network reticulation 

 as in head, except a belt across disc. Pterothorax widest at 

 junction of meso- and metathorax. Legs much as in allies, 

 hind-tibige long, slender basally. Wings reaching to sixth 

 abdominal segment, fore-wings slightly upturned distally, 

 with veins (including marginal) strong ; upper vein fused 

 with costa ; lower vein joining the hind-margin at or just 

 before the distal sixth. Costal fringe of about fifteen curved 

 sette; lower cilia also sparse, fun^ate, rather long, slender, 

 and wavy. 



Abdomen comparatively heavy, elongate-ovate, and about 

 1*4 times as broad as the pterothorax at broadest. Tentli 

 abdominal segment long, more than twice as long as broad 

 near base, divided above. Apical setaj vestigial, a pair on 9, 

 at hind angles, only about 0'3 the length of segment 10.
