described above agree absolutely, I think Ihave correctly paired them, while, if the female 
of this species be variable, Mr. Moore’s description would be correct.” (de Nicéille, 1. c.) 
Females from Masuri and Sikkim since obtained agree also with my description of that sex, 
and not with Mr. Moore’s. Colonel Lang reports C, alboceruleus from “Naini Tal, 5,500 
to 8,600 feet (Cheena), May, andagain August to October.” Mr. Doherty records it from 
“* Khati, N.-W. Kumaon, 7,000 feet, rare.” It occurs rarely in Sikkim in March, April, May, 
October, November, and December. It has a rather more extended range than C. mavginata, 
mihi, as it occurs to the west as far as Simla at any rate. I am unaware, or have failed to 
recognise, that there is any seasonal dimorphism in this species. It is a rare species, but is 
very easily recognised. 
I append as a foot-note Mr, Moore’s original description of this species. *

DESCRIPTION: “ MALE. UPPERSIDE, 40th wings lavender-blue. Forewing with the 
costal margin somewhat broadly, and the outer margin very broadly, especially at the apex, 
dusky black ; a patch of irrorated white scales on the disc between the third median nervule 
and the submedian nervure, obsolete in some specimens, Aéndwing with a broad even 
outer black border, somewhat divided by a series of bluish lunules, which are most prominent 
at the anal angle, and often enclose black spots. UNDERSIDE, 0th wings white, slightly tinted 
with blue. forewing with a slender dusky disco-cellular streak, a discal series of six elongate 
spots, arranged ina regular sinuous line in some specimens (as in the female figured), or 
in others more irregularly (as in the male figured) ; a submarginal lunular line, a marginal 
series of linear spots, anda fine anteciliary line. Aindwing with the spots arranged as in 
C. puspa, Horsfield, but they are less prominent, those on the margin reduced to linear marks. 
Cilia white on both sides in both sexes. FEMALE. UPPERSIDE, 0th wings very deep blue, almost 
black. Forewing with a broad pure white patch from near the subcostal nervure to the 
inner margin, a prominent disco-cellular streak, and the base thickly irrorated with deep 
blue scales. Ainzdwing with the outer margin rather less deeply blue than in the forewing, and 
bearing a series of pale lunules including Elack spots, the disc white but irrorated towards 
the abdominal margin with blue scales, as is also the base of the wing. In some specimens the 
white area on both wings is much restricted, appearing on the hindwing only at the middle 
of the costal margin, UNDERSIDEas in the male.” (de Wicéville, 1. c.) 
I have figured and described as above the form of both sexes of this species which occurs 
in Sikkim in the rains. The form which is found in the spring and autumn (dry-season) 
differs very considerably : in the male the blue coloration of the upperside of the male 
is much lighter and less purple, and the costa, apex, and outer margin are very 
narrowly black. The forewing has a patch of white on the disc quite as large as in C. 
albocaruleus, Moore, and it reaches the inner margin. The hindwing has a large patch of 
white from the apical half of the costa to the middle of the wing ; all the rest of the surface is 
powdered with blue scales, and is crossed by the darker veins ; there is a fine anteciliary black 
line, but no broad outer black border as in the rains form. All the spots on the underside of 
both wings are much less prominent. The female differs quite as much. The base, apex, and 
outer margin are less broadly black, leaving a pure white discal patch twiceas large as in the 
* “Mateand FEMALE. Uppersine, doth wings pale clear blue, discal area of the forew/sng and apical area 
of the Aindwing white. Forewing with a broad outer marginal black band terminating in a point at the posterior 
angle in the male, but not reaching the angle in the female. A¢mdwing with a narrow marginal black line 
and a series of small indistinct spots, the latter still less apparent in the female. Czd/a white, with an inner 
bordered line adjoining the band on the forewing. UNDERSIDE, 40th wings white, with small and slender black 
markings disposed | ‘similarly to those in P, [=C.] puspa, Horsfield, but without the lunular line encompassing 
the marginal spots.” (J7oore, 1. c.)
