(J ? . The smallest species of the genus, variable iu tint. Palpns, breast and 

 first two abdominal sternites paler than in the other species, more jiinkish. Wings 

 not dentate, or the teeth very faintly indicated, but forewing distinctly angnlate at 



11^. ^Forewiug : the oblique distal band diffused posteriorly ; the first discal line 



rather heavy, continuous ; 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 luniiles of the same colour. 



Underside: both wings different from those of all the other s]iecies. 



Forewing : a subapical, costal, triangular, chestnut j)atch 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 subajiical jiatch ; jiinkish grey submarginal scaling 

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



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



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



(J. Harpe (PI. XLVIII. f 25) remarkably diff"ereut from those of the other 

 species, being much prolonged. Penis-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 i)late (PL XLl. f. 10) widely different from that of most other 

 s]iecies, the difference corresponding to that found in the harpe of the S ; sides of 

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

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

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

 membranaceiius, 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 socratcs in the narrower lateral 

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

 of socndcs f. vinerea.
