40 LYCAENIDAL. PORITIA. 
from the base beneath the cell (in? some specimens encroaching within) to the exterior 
margin, within which is a row of more or less defined marginal and submarginal black 
spots, exterior margin defined by a black line, abdominal and anterior margins greyish-black, 
a tuft of fine greyish hairs near the base. Zorax above greenish-black ; addomen black ; 
antenne black, ringed with white; Zead and palpi above hoary; palpi and ¢horax beneath 
and /egs white, tibiz and tarsi with black spots. UNDERSIDE, 40th wings very pale ashy 
colour, covered with numerous transverse irregular-shaped black-bordered pale brown mark- 
ings, those at the base short, a series across the disc zigzag, others along the exterior margin 
with narrow inner white lines, posterior angle of both wings witha black spot bordered 
above with orange-red. FEMALE. UPPERSIDE, both wings brownish-black. Forewing with 
a pale orange-yellow streak in the middle, above and beneath which are purple-blue 
connected streaks. Aindwing with ill-defined purple-blue marginal and discal spots, 
exterior margin defined by a very narrow yellow line, which is bordered within by a 
similar white line. Ci/éa in both sexes alternate brown and white.” (AZoore, 1. c ) The extent of 
the blue area of the upperside in the male is very variable in different Sikkim specimens. 
In one extreme the elongated black spot in the submedian interspace in the forewing is 
entirely absent, as are also the marginal and submarginal black spots on the hindwing. 
The underside of both wings in both sexes of Sikkim specimens varies much in the 
ground-colour, being in some specimens pale ochreous-white, in others ashy ; the prominence 
of all the markings is also very variable. It occurs in Sikkim in October and November, 
I have received specimens also from Sibsagar in Upper Assam taken by Mr. S. E. Peal, 
from the Chittagong Hill Tracts taken by the late Mr, H, M. Parish in November, and 
one female from Tsenbo in Upper Burma taken by Major C. H, E.. Adamson in May. 
Mr. W. Doherty has given me the following description of the egg of P. hewitsoni:— 
“Egg a truncate pyramid, half again as long as wide, with two vertical, two sloping, and 
two horizontal faces, reticulate above as is usual inthe Zyce@nide, It is the most remark- 
able egg known to me among Butterflies, and I was particularly anxious to examine other 
species to see whether this form was constant or not. But although seven species of Poritia, 
all very conspicuously coloured, are described from the Malay Peninsula, I have not ob- 
tained a single specimen of any of them during my stay here [in Perak] from the middle 
of May to the middle of November. The seven known species were mostly taken at Singapore, 
though that locality would seem to be very unfavourable for rare insects on account of the 
absence of virgin forest.” 
Mr. Doherty has described a variety (or better, local-race) of P. ewitsont under the 
name of favoyana chiefly on the coloration of the upperside of the female as follows :— 
“* Taken commonly at Myitta, Tavoy. The males are remarkably variable, many are 
wholly indistinguishable from those of P. phraatica, Hewitson, I have taken every variation 
from those resembling Mr. Distant’s figure of P. phraatica to those with an irregular blue 
area below the cell, wholly separate from a long submedian streak and a solid oblique sub- 
apical band. The underside varies greatly, and does not differ from that of P. phraatica. 
The female is pale blue over fully one-third of the forewing, and has more resemblance to 
the male than to the northern female with its small blue area. In the Tavoy form this ex- 
tends from the cell to the hind margin projecting in the interno-median interspace within 
one-eighth of the outer margin ; there is a blue spot in the cell, and a variable subapical 
band sometimes obsolete. The ochreous discal spot of the forewing is occasionally pre- 
sent, The blue area on the hindwing is variable but usually considerable,” (Doherty, 1. c.)
