formed bv veins R' ami M' always black, even iu the s|i(Himeiis with the baud miiili 

 widened; black triangular space before base of M- at least 1 mm. (generallj- 2 mm.) 

 wide at M-; no white or bluish white scaling at outer side of band; discal spot 11' — li- 

 very variable in size and shape, ofteu with a second, smaller, spot in front ; sub- 

 marginal spot SC'' — R' also variable, ofteu absent, seldom with a spot in front or 

 another behind; cell only in the extreme specimens of the Himalayan spring brood 

 with pale scaling (Nov. ZooL. V. t. X. f. 3), such specimens also with pale scaling 



at costal margin. Hindwing : discal band triangular, reaching submedian fold, 



where it is mostly joined to snbanal, abdominal, more or less triangular, pale patch ; 

 inner edge of band well defined in the dark forms, less so in the North Indian sjiring 

 brood with extended band ; outer edge concave from C to IV and then again from 

 R' to M-, or nearly evenly convex (in the specimens with extremely wide band) ; 

 at distal edge of band, beyond 51-, a trace of a pale bine Inunle, iu extreme si)ocimeus 

 of the spring brood (N. India) often with three very thin Inuules between K-' and 

 SM-; a complete series of white submarginal dots, the dot before S(.'- often absent; 

 admarginal spots tawny ochraceous, transverse, often obscure or obliterated, anal 

 one generally better defined and varying in tint from ochraceous to buff; tails 

 generally with bluish metallic plumbeous lines, the hinder line of second tail often 

 continued along anal margin of wing to subanal abdominal pale patch ; last two 

 white submarginal dots mostly with jjale blue scaling at outside; black submarginal 

 spots (between the white submarginal ones and the admargiual spots) not clearly 

 marked; fringe white at anal angle; tails pointed, varying in length. 



Uiulersidc : discal band exactly as wide as above, but greenish white. 



Forewing : middle cell-bur represented by two dots, encircled with white, the upper 

 often wanting, the lower closer to point of origin of M- than to base of wing, 

 upper cell-bar very obliijuc, continuous with submedian bar M- — (SM'), edged white 

 proximally, somewhat bi-undulate ; median bars M' — (SM') also continuous, bar 

 j{,3 — M' a little more distal, mostly prolonged a little along R^, and often not 

 separated at M' from point of origin of R'; bar D thin, heaviest in front behind R-; 

 median bar R- — R^ mostly absent, but sometimes indicated about midway between 

 cell and discal bar, median bar R' — R- always present, forming the proximal border 

 of the discal greenish white patch R' — R-, median bar 8C= — R' only present in 

 specimens which have also the respective greenish white discal spot marked ; discal 

 bars R^ — SM= mostly forming the outer border of the discal band, but ofteu 

 separated from it, especially bars R' — M^ by a rufous interspace, the bars themselves 

 sometimes rufous, discal bar R-— R^ rather heavier than the others, bars SC^ — R- 

 mostly rather thin, straight or convex, seldom slightly concave, bar SC — SC"' seldom 

 marked, but always present in the specimens which have a submarginal spot between 

 those veins; postdiscal and submarginal bars joined to form strongly arclied lunules 

 between R- and (SM'), bars SC— R- forming mostly rings, upper postdiscal bars 

 often (sometimes all the discal bars) rufous; a black jiatch behind (SM') replacing 

 the last postdisco-submarginal lunulc, another patch behind SM-; interspace between 

 submedian and median lines of bars olivaceous, mostly more or less rufous chestnut, 

 this chestnut, colour extended between R- and R' distad to discal bar, forming mostly 

 a patch at the proximal side of that bar, sometimes also cellules SC!^ — !{'- more or 

 less rufous chestnut ; outer marginal area olivaceous, rest of wing vinaceous fawn 



colour, shining in side-light. Hindwing : submedian line of bars just outside the 



praecostal vein, bordered white proximally, concave, continued a little beyond M ; 

 median line of bars entering cell at origin of It'-, crossing ]\I at or a little beyond oris^iu
