<S ? . The smallest species of the genus, variable in tint. Pal])U«, breast and 

 first two abdominal stcrnites paler than in the other species, more jiiukish. Wings 

 not dentate, or the teeth very faintly indicated, bnt forewing distinctly augulate at 



W. Forewing : the obliipie distal band diffused ])osteriorly ; the first discal line 



rather heavy, continnous ; the greyish costal subapical area either stopping at R', 

 or extending beyond this vein ; the curved pinkish grey submarginal line broad, 

 generally continuous with the apical lunules of the same colour. 



I'tidersule : both wings different from those of all the other sjiecies. 



Forewing : a subapical, costal, triangular, chestnut patch extending to R', straight 

 proximally, where it is bordered by a grey or pinkish grey line or patch ; the outer 

 disc between R' and SM- ferruginous tawny or pinkish vinaceous, or vinaceous 

 cinnamon, not so dark as the subapical patch ; pinkish grey submarginal scaling 

 extended, diffuse, basal half of costal margin mostly of the same colour as the 



hiudwing. Hindwing : brown marginal border vestigial, narrow, sometimes 



better marked, reaching at R^ only half-way to the second pair of discal lines. 



c?. Harpe (PI, XLVIII. f ",'5) remarkably different from those of the other 

 species, being much prolonged. Peuis-sheath (PI. LV. f. 24) with a broad left 

 process which is rounded at end and is dentate at the distal and proximal edges ; 

 f. 23 represents the sheath in a dextro-lateral view. 



?. Vaginal plate (PI. XLI. f. 10) widely diftereut from that of most other 

 species, the difference corresjaondiug to that found in the harpe of the S ; sides of 

 the plate nearly ]iarallel, suddenly converging near end, apical part narrow, deeply 

 concave ; orifice of vagina covered by a halt-cylinder, the apical edge of which is 

 sinuate, the proiuinent lobes obliquely rounded ; proximal part of the plate sub- 

 membranaceous, almost regularly folded, while the lateral parts are smooth and 

 deeply concave at the sides of the half-cylinder. 



Larva, as figured by Butler, differs from that of socrates in the narrower lateral 

 line ; the figure given in Horsfield & Moore, I.e., has a broad line, and may be that 

 of socrates f. cinerea.
