spurs very unequal, short one less than half the length of the 

 long ones, these not quite half the length of first tarsal segment. 

 Fore wing underside with black streak behind cell, hinder 

 margin in <$ about as long as, in P 4 to 6 mm. longer than, 

 distal margin ; the pale costal area on fore wing above distinct . 

 Expanse : $ 94-136 mm., $ 112-150 mm. 



S- Tenth abdominal tergite (fig. 31 A, B) very different 

 from that of all the other species, its apical half being very 

 strongly narrowed with the apex not sinuate ; underside of 

 this narrow portion strongly chitinized, having the appearance

 (x.£, 10th tergite ; x. v, 10th sternite) ; C, <$, harpe (cm, submesial 

 ridge ; pb, basal process ; pdb, dorsal-basal process ; pv, ventral 

 process) ; D, 2, vaginal plate ; E, 2, vaginal plate and 8th tergite, 

 lateral aspect (vni, ix, x, tergites; v, vaginal orifice). 



as if the sides of the tergite, instead of being spread out laterad, 

 were bent downwards and had become fused together in the 

 mesial line ; tip of the tergite curved ventrad, forming a hook 

 which is vertically thicker (side-view) than in the allied 

 species, owing to the under surface slanting from each side 

 towards the raised mesial line ; sternite also very remarkable, 

 being produced into two long processes. The harpe (fig. 31 C)
