 largost and contiguous, followed by a submaririmtl ami marginal scries of waved and linear fireyisli spots, 

 between which the colour is somewhat paler. Posterior wings with a suhmargmal series of greyish 

 spots placed between the nervnles, followed by a series of subcorneal spots of the same colour, which are 

 placed conjointly in pairs between the nervules ; marginal spots as on anterior wings, but more hmulate ; 

 fringe of l oth win^s alternately greyish. Wings beneath brownish oclii-aeeous ; anterior wings with the 

 marginal and submargmal markings as above, the macular fascia at end of ceil subobsoleto and greyish ; 

 the basal half of winu is pale carttjtneotis, with the costal area and cell marked as in male; posterior 

 wings with the marginal and submarginal markings as above, and the centre crossed by a faint greyish 

 fascia more or less corresponding to that on the wings of the male.

There is no doubt of this being a variable species, though we need not necessarily follow 

 Mr. Kirby* to the full extent of his varietal speculations, and though, in one philosophical 

 sense he is most probably correct, on the other hand a number of local races have now become 

 so well established that the much -vexed, contested, and, in some quarters, almost deified term 

 " species" must necessarily he applied. t The two males which I have figured — the first from 

 Quedah ami the second from Province Wellesley— sufficiently show inconstancy of type, and 

 Dr, Aurivillius J has added (and doubtless correctly added) several names to the synonymy, 

 which I have only refrained from copying here, owing to the exigencies of the treatment of a 

 local fauna. § 



The late Mr. Darwin, in reference to his theory of " sexual selection," lias drawn attention 

 to the colour-markings of the male of this species, to which his attention had been called by 

 Dr. Schulte, of Fiirstenwalde. The markings of the male when viewed from behind are pure 

 white, " but when viewed in front, in which position, as Dr. Schulte remarks, the male would 

 be seen by the female when approaching her, the white markings are surrounded by a halo of 

 beautiful blue."|| 



The Bros, de Alwis have given drawings of the larvti and pupa of this species as found in 

 Ceylon, 11 which Mr. Moore has described** as 11 Larva purple-brown ; head armed with two 

 long erect branched spines, the segments with a dorsal row of three (two only on the anterior
