of polyxena. Forewing : median bars R- — M' more or less marked, but bars 



SC* — R^ not present, or very faiatl}' indicated ; disc pale buff yellow, paler in front 

 than behind ; discal barsi M' — SM- faintly indicated as orange buff lunules, the 

 respective postdiscal interspaces therefore not clearly separated from the discal area, 

 the same is the case with interspace R' — R^, the black area convex between 

 M.^ and SM^, but incised at (SM'), also convex between the veins from R^ — M-, 

 more produced proximad between R- and M\ sinuate between R' and R^, here only 

 6 — 7 mm. broad ; postdiscal interspace SC* — R' sometimes separated from the 



discal area. Hindwing : discal area pale buff yellow in front ; median bars 



O -R2 marked ; postdisco-submarginal patches all with the proximal portions 

 developed, hence the white dots within the patches, patch R^ — R' a little larger 

 than patch R' — R-, white dots large, especiall}' upper two. 



Underside as in the palest specimens of repetitus, median interspaces of 

 forewing less brown, much shaded with buff; discal interspaces R' — SM^ of fore- 

 wing much broader than median ones ; tail short, rounded at tip, not spatulate. 



Length of forewing : J, 35 — 37 mm.

S. Wings above as in bright specimens of repetitus. Forewiug : median 



bars not marked ; black outer area variable in width in front, always very narrow 

 behind, measuring about 5 mm. behind BI^, and 18 to 21 mm. at R', sometimes inter- 

 rupted at (SM'), in which case the tawny admarginal patch M- — SM^ is connected 

 with the liasi-postdiscal area ; discal bar M" — SM" absent, or indicated as a faint 

 tawny lunnle, bar M' — M^ black in upper half, bar R^ — M' also black, mostly 

 completely merged together with the black area ; tawny postdiscal interstitial 

 spot R'— R^ sometimes present. Hindwing : proximal portions of postdisco- 

 submarginal patches R' — SM'' absent, hence white dots at proximal side of the 

 remaining submarginal portions of the black patches, size of these patches variable, 

 but patch R'— R- smaller than the following two or three. 



Underside bright ferruginous tawny, discal interspaces paler proximally, bars 

 very prominent, especially on account of their conspicuous white borders, discal 

 bars regularly arched, on the whole more deeply concave than in the other forms 



oi polyxena. Forewing : position of bars as variable as in repetitus and other 



subspecies of poli/xena, but median bars R- — SM- rather more often continuous ; 

 white submarginal scaling prominent, distally generally limited by black scaling. 



Hindwing : admarginal interspaces ochraceous, submarginal black, blue, white 



spots prominent ; tail 4 — 7 mm. long. 



? . Resembling certain ? ? of repetitus. Wings ahore, discal area white, with 

 a yellow tint, more distinctly yellow buff at internal margin of forewing, on 

 hindwing the pale colour gradually merging between R^ and M' into the tawny 



colour of the basi-discal area. Forewing : median bars SC'-*— M^ marked ; 



discal bars R' — M" very thin, deeply arched, the postdiscal interspace M' — M- nearly
