The four costal black dots at the base of tlie forewiug are mostly separated from 

 one another ; the two outer ones are, however, sometimes connected with each other 

 by a black line situated along the costal nervnre; between spots 2 and 3 there is a 

 slight indication of a fifth costul dot. Tlie wliito area of tlie forewing is ratlier deeply 

 indented at veins 3 and 4, and the submedian fold is in most specimens more or less 

 obviously marked with brown scales. The white patch at the anterior angle of the 

 cell stands isolated from the white area: its length varies in our series from 

 3 to 4 mm. 



The black spot in the middle of the cell of the hindwing is sometimes minute, 

 sometimes as large as the spot at the apex of the cell.

The upperside of the thorax and the base of the forewing are generally brighter 

 yellow than in the preceding subspecies; the basal black spots of the fore wings are 

 larger in most individuals, the two outer ones of the four costal dots are usually 

 merged together; the white area is less indented at veins 3 and 4; the submedian fold 

 has no brown scales within the white area; the white jiatch at the anterior angle of 

 the cell is larger, measuring in length from 4 to (i mm., and is nearly always con- 

 nected with the white area by means of white scales between veins 5 and 0. The 

 black s])ots of the iiindwing vary much in size in the various specimens: the hi'owii 

 bordcrof the hindwing is sometimes very narrow. 



Our single specimen (cj) from Upper Tonkin lias the white area of the fore- 

 wing above only slightly sinuate at the submedian fold; on the underside tlie outer 

 edge of this area is regularly convex, with indentations at the veins. 



The specimens from the Loo C'lioo Islands agree jjartly very well with Indian 

 examples, but in most of them the white patch at the apex of the cell is joined to 

 the white area of the forewing ; in one d and two ? ? the white colour of the fore- 

 wing above has so much increased in the costal region as to encircle the black sjjot 

 at the a])ex of the cell. 



In cull. Staudinger there is h vi'iIa from Darjiling (ex coll. Atkinson) which 

 has the basal half of the forevying below snlfused with brown scales; on the hind- 

 wing below there is a limad brown streak extending from the central spnt ul' (he cell
