LYCA‘NID&. CYANIRIS. 109 
in the shade of the blue on the upperside of the male is the chief character by which the two 
species can be distinguished, though the spots onthe underside of the forewing are rather 
more irregularly placed in C. Zimdbatus than they are in C. singalensis.

HaBiraT: Ceylon. 
EXPANSE: @, 1°3 to 1°53 9, 1°2 inches. 
DEscRIPTION: ‘‘MALE. Uppersipé, doth wings very dark blue, Czlia white, with 
blackish inner marginal border. UNDERSIDE, doth wings white. Forewing with a dusky 
brown streak atthe end of the cell, a submarginal transverse linear row of four [or five] linear 
spots, a spot near the costa, and a marginal row of dentate spots. Mindwing with two 
equi-distant brown spots on the anterior border, a spot within and a streak at the end of 
the cell, a curved discal series of five spots, two lunate marks on the abdominal border, and 
an outer marginal row of dentate spots. 7%ie and ¢arsi with black bands.” 
“Near to P. kasmira” [=G. celestina, Kollar]. (Afoore, 1. c. in Ann, and Mag, of Nat. 
Hist.) 
FEMALE. UPPERSIDE, forewing glossy bluish-purple, outwardly paler; the costa some- 
what broadly, the outer border more broadly and decreasingly black. Hindwing rather 
paler than in the forewing, the costa bounded posteriorly by the costal nervure and its second 
branch black, a series of oval black spots between the veins on the margin, the veins out- 
wardly black, an anteciliary black line. Cz/éa whitish, UNDERSIDE, both wings as in the male. 
The nearest ally to this species is C. /émdbatus, Moore, especially specimens of that species 
from Shillong. It may, however, be known by its very dark lavender-blue colour on the 
upperside of the male, and by the discal spots on the underside of the forewing in both sexes 
being arranged almost in a line and divided only by the veins ;in every other Indian species 
they are arranged more or less angle to angle. It appears to be the commonest species 
of the genus in Ceylon. Mr. Hutchison records it from the ‘* Central Province ; hills, 3,000 
to 6,000 feet, in forest land, at all times. Gregarious. Settles by hundreds in damp spots on 
the roads.” Wade records it from Kandy, and Messrs. Mackwood and Fairlie have sent 
me specimens from Lindula, Punduloya, East Matall, Masdeliya, Lagella, and Kakgalla.

DESCRIPTION: ‘* MALE. UPPERSIDE, doh wings lilac-blue. Cilia white, with an inner 
black line. Forewing with a very narrow exterior marginal black band. Aindwing with a 
very narrow marginal black line and a few minute speckles at apex. UNDERSIDE, doth wings 
white, with slender dusky markings, as in P. [ =C. ] puspa, Horsfield.” 
“ Differs from P. [=C.] dilectus, Moore, in its more pointed forewing, darker colour, and 
more prominent marginal line.” (A/oore, 1. c.) 
FEMALE. UPPERSIDE, forewing with the costa, apex and outer margin broadly black, 
the rest of the wing iridescent bluish-purple, paler outwardly ; a somewhat indistinct disco- 
cellular spot. Windwing blue, the veins, costa and outer margin broadly black, the latter bearing 
series of blue well-formed lunules. UNDERSIDE, doth wings as in the male. Described from 
a specimen from Shillong. 
There is no difficulty whatever in distinguishing this species from C. dilectus, the latter 
being of a much lighter blue colour on the upperside, and almost always having irrorated 
patches of white on both wings. It is very much nearer to C. danka, Moore, the latter, however, 
in the male being still darker on the upperside, the narrow black border still narrower, and the 
discal series of spots on the underside of the forewing arranged almost ina connected line, not 
well-separated and irregularly-placed as in C. /imbatus. It differs from C, séngalensiss
