LYCANIDA. PORITIA. 39 
The genus /oritia is a particularly difficult one, as the males of several species appear to 
possess no constant characters by which to distinguish them ; while the females, though variable, 
present considerable and well-marked differences. The blue markings in the female on 
the upperside when present are iridescent, as are those of the male, but to a rather less extent. 
All the species appear to be rare and but seldom caught in perfect condition. 
The complete transformations of no species of the genus is known, but a description 
of the pupa of ?. hartertit, Doherty, will be found under the description of that species. 
The genus appears to be strictly confined to the Indo-Malayan region.. In India it occurs: 
only in Sikkim eastwards to Assam, thence southwards through Burma to Singapore, several 
species being found in Sumatra, Java, and Borneo, 
Koy to the Indian species of Poritia. 
A. Both sexes, underside, both wings closely covered with catenulated bands of annular spots. 
a. Female, upperside, both wings more or less marked with blue. 
a‘. The blue coloration less extensive than the black, often with some ferruginous spots’ 
on the forewing.

DESCRIPTION: “MALE. UPPERSIDE, doth wings jet-black. /urewing with the lower 
part of the base from beneath to beyond the cell and extending into the black of the 
exterior margin brilliant deep blue, or in’some lights emerald-green, in the middle of which 
is an elongated black spot, a row of very small similar brilliant blue spots obliquely before 
the apex and along the exterior margin. AHindwing with the same brilliant blue extending 
deeply concave; second median nervule originates considerably before the lower end of the cell. HinpwinG 
broad, outer margin scalloped, costal nervure shorter than in Deramas, ending considerably before the apex of 
the wing ; second subcostal nervule originates considerably before the end of the cell, second median nervule even 
more so ; discoidal ced/ with its end-truncate, not oblique; #pfer disco-cellular nervule oblique, hardly half as 
long as the lower ; ower disco-celludary regularly and strongly incurved. Aztenx@ more slender than in Deramas, 
the club more distinct ; Ja/fz with the last joint still longer and more slender and acute. And /egs with the first 
joint of the tarsi not perceptibly swollen. ove /egs with the femur enlarged, longer than the tibia ; tarsus hardly 
two-thirds as long as the tibia, clavate, not articulate, with a few short spines, claws small, slender, partially 
concealed, accompanied by the usual hairs, but with no paronychia. J/iddle and hind legs with five distinct 
joints, claws, paronychia, and pulvillus. Male with a tuft of long hairs on the upperside of the hindwing in the 
cell. This description is based on a single male of J. clorznda.” This MS. species is the male of P. fotina 
Hewitson. : 
As Mr. Doherty describes his genus 4vassaga in comparison with Porttia, I give his definition of the 
latter : ‘‘In this genus the upper discoidal nervule of the forewing originates at the end of the discoidal cell, 
so that there is a very short upper disco-cellular nervule; the middle disco-cellular is upright and very slender ; 
the lower disco-cellular obsolescent. In the hindwing the disco-cellular nervules are also very slender, the upper 
rather long ; the second median nervule is giyen off opposite to the lower end of the cell. The apex of the 
forewing is rather rounded, the upper part of the outer margin being strongly rounded. .The markings of the 
underside are annular and exceedingly variable. The sex mark at the base of the hindwing of the male is a 
conspicuous tuft of black hairs on a dark ground. The hiudwing of the female is less angled outwardly than 
in Massaga.” (Journ, A. S. B., vol. lviii, pt. 2, p. (1889).
