torj^ite (AV/) ajipears as a lung strong' hook, while the steruite (AV) is a small 

 fold : the length of the tergite as compared with that of hi'entttA can be best seen 

 from PI. XXV. f. 3. 4. The dorsal lobe of the clasper (IV/) is rather w.^ak, apically 

 dilated and bent inwards, irregularly ladle-shaped, the ventral lobe ( Tc) ends in 

 two heavy teeth : the impair process common to both harpes ijir) is fishtail-shaped : 

 tlie lateral processes of the harpe are very unequal, that of the right harpe (^pdl) 

 being long and pointed, projecting beyond the ventral edge of the clasper, while 

 the process of the left clasper {jirlr) is short and more or less obtuse. The needle- 

 like jirocess (//) between clasper and tenth sternite vei'y prominent. 



?. Eighth tergite (PI. XVIII. f. 5) with a sharp prominent cone upon the 

 upper surface at each side, pointing distad. Vaginal armature (PI. XVIII. f. 1) 

 witii a large postvaginal i)late {prp) which is very prominent ; the distal margin 

 slightly bi-emarginate, the mesial portion somewhat produced and bent ventrad. 

 so that the plate appears mcsially almost sinuate in an anal aspect ; the angles of 

 tlie plate rounded.

?. Only one badly damaged s])ecimen, which is, however, so pecniiar in the 

 structure of tlie copniatory organs that we do not hesitate to make it the type of 

 a name for tliis new subspecies Large, general colour nearly as dark as in 

 ti-ilin. inidatiis, more ashy grey on body and base of forewing ; forowing with traces 

 of a double submedian line which cnjsses M at tlie base of M', discal line evenly 

 concave, slightly angled just before inner margin. Upperside of mid- and iiindtibia 

 purer white than in iiiuhttuK. 



Eighth tergite (PI. XV III. f. s) with an enormously developed, deeply 

 sinuate, irregularly notched and rugate plate, which is homologons to the two 

 cones of the tergite of frilln. i(n(lnfi(.<. The jiostvaginal ]>late (PI. XVIII. f. 4) 

 is also remarkably ditferont in being rather drepjy sinuate, witli the tivo lobes 

 rounded.

S. Upper lobe of clasper rounded, prujeeting lieyond the lower lobe, which 

 is obliquely truncate with the ventral angle somewhat produced (PI. XXXIV. f 9) : 

 the unpair process pr found in the other subspecies is here deeply divided into 

 a narrow and shorter right jiiece and a longer and broader, ajiically pointed and 

 somewhat denticulated, left blade (PI. XXXIV. I'. 7); this structnre shows that
