cJ ?. Mid- iind bindtilda white ubove ; the latter in S as long as, iu ? 2 mm. 

 longer than, the first tarsal segment ; ^lllll•s very uueqnal, short ones less than 

 half the length of tlie long ones, tliese not quite half the length of the first tarsal 

 segment. Forewirjg below with black streak behind the cell, hinder margin in 6 

 about as long as, in ? 4 to 6 mm. longer than, distal margin ; the pale costal area 

 on the forewing above distinct. 



6. Tenth abdominal tergite (PI. XXIII. f. 24) very different from that ot 

 all the other species, its apical half being very strongly uarroweil with the apex 

 ?iof sinuate ; the underside of this narrow portion is strongly chitinised, having 

 the appearance 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 ; the tip 

 of the tergite is curved ventrad (PI. XXIII. f. 2b), 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 (c) ; sternite also very 

 remarkHble, being produced into two long processes (PI. XXIII. f. 24). The harpe 

 (PI. XXXII. f. 11) consists of a ventral triangular ridge jjc, which is subvertical 

 upon tlie plane of the clasper and covered for the greater part with small scales ; 

 the subraesial ridge cm is basally produced into a comjjressed process ^^i, while it 

 fades away distally into the vermicular folding of the clasper; the dorso-basal process 

 jj(/b is slender, curved, apically dilated and here beset with bristle-bearing tubercles. 



? . The eighth tergite very different from that of the other species iu being 

 dee)ily divided by a narrow sinus (PI. XVI. f. 5. 6), the two lobes more or less 

 notched or irregularly emarginate. The vaginal plate also characteristic (PL XYI. 

 f. 4. 5) : the vaginal orifice (c) mesial, surrounded proximally and laterally by a 

 fold, at each side of the orifice there is a groove bordeied by a fold ; the postvaginal 

 plate very broadly rounded, almost truncate, extremely feebly emarginate mesially ; 

 fig. gives a side-view of the end of the abdomen, showing the relative position 

 of the dorsal and ventral })lates ; the anal cone (consisting of segments ix. and x.) 

 is somewhat pushed auad to make it visible.
