into an exceptionally prominent iiunip, witli anterior ocellus 

 facing forwards at sununit and the posterior pair evidently 

 flanking the sides. 



Prothorax only about 0*7 the lengtli 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 nieso- and nietathorax. Legs much as in allies, 

 iiind-tibite 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 o£ about fifteen curved 

 setfe; lower cilia also sparse, fuinate, rather long, slender, 

 and wavy. 



Abdomen comparatively heavy, elongate-ovate, and about 

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

 abdominal segment long, more than twice as long as broad 

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