Both sexes of this form were described by Feisthamel in 1850 as ephyra. 

 Dr. Butler, in 1865 and 1896, failed to recognise the identity of Feisthamel's insect 

 with his own viola. What Dr. Butler considered in 1896 to be c?<? of viola are 

 ephyra Godart, not ephyra Feisth. = viola Butl. Aurivillius, with wonted careful- 

 ness, put the synonymy right.

(?. Body above olivaceous black, head and pronotum with the usual white dots; 

 underside huffish white, abdomen rather darker. 



cJ. Wings above black, with a strong hyacinth blue gloss. Forewing : a 



postdiscal campanula blue band from SC^ to internal margin, composed of seven 

 spots, the first, third and fourth a little more proximal than the others, the band 



gradually broader behind, patch M^ — SM^ measuring 3 mm. in width. Hindwing : 



band of forewing continued across disc to abdominal fold, its proximal margin convex 

 before cell, where the band is 4| mm. broad, its outer margin nearly straight, but 

 indented upon the veins ; a series of purplish blue submarginal dots ; admarginal 

 interstitial markings transverse, purplish blue, extending into tails, where they 

 become whitish, anal one olive grey ; abdominal fold pale brown, a triangular, 

 grey, patch beyond end of SM^. 



Underside silvery white. Forewing : cell-bars similar to those of the allied 



species, bar 4 bent distad in middle ; submedian bar M^ — (SM') just behind base 

 of M-, submedian bar M' — M- proximal of base of M' ; median bars forming a 

 nearly continuous line, 2 J mm. distant from cell at R^, only lA mm. at R^ ; discal 

 bars situated in a brown band which runs from costal to internal margin, is nearly 

 straight, begins 11 mm. from apex of wing and crosses SM^ 6 mm. from its end ; 

 to this band is joined a large, double, blackish brown, patch M- — SM- ; postdiscal 

 bars, bars SC — M^ represented by a pale brown, rather indistinct, zigzag line, while 

 bar M^ — M^ is larger, blackish, and halfmoon-shaped ; outer margin brown; 



submarginal, white, interspace M^— SM- resembling the number 3. Hindwing : 



basal and subbasal costal bars, and subbasal bar G— SC^ absent ; submedian and 

 median bars forming two nearly continuous lines, pale russet wood brown ; the 

 series of discal and postdiscal bars parallel, situated in a faintly curved, tawny, band 

 of 2^ mm. breadth, nearly parallel to outer margin, crossing C 3 mm. from its 

 end, discal bars linear, curved, postdiscal ones more rounded, except the last ones 

 which are also linear and curved ; submarginal bars abbreviated, but transverse, 

 last two rounded, minute; admarginal, interstitial, markings transverse, ochraceous, 

 bordered at both sides with a very thin white line, anal one olive ; tails slender, 

 acute. 



?. Unknown. 



Length of forewing : 31 mm.
