as foot-notes.* The latter compares it with C. favana, Kollar, to which it has not even a 
distant relationship. 
The figure shews both sides of a male example from Gunduk, Biluchistan, in my 
collection, 
Gonus 189.—ILERDA, Doubleday. (PLare XXVIII). 
Ilerda, Doubleday, List Lep. B M., vol. ii, p. 25 (1847) ; id., Hewitson, Ill. Diurn. Lep., p. 57 (1865) ; 
Heliophorus, Geyer, in Hiibner’s Zutrage, vol. iv, p. 4o (1832).T 
FOREWING, triangular, costa gently curved, male with the afer acute (much rounded in 
I. sena, Kollar), outer margin nearly straight or somewhat convex (much rounded in JZ. sena), 
inner margin straight ; in the female the apex is move rounded than in the male, and the outer 
margin is very convex ; costal nervure terminating about opposite to the apex of the discoidal 
cell ; first subcostal nervule well removed from the costal nervure, originating at about two- 
thirds of the length of the discoidal cell from its base ; second subcostal with its base nearer to 
that of the upper discoidal than to that of the first subcostal ; ‘Aird subcostal somewhat long, 
given off about midway between the apex of the cell and of the wing; «per discoidal 
nervule originating exactly at the point where the middle disco-cellular nervule is given off ; 
middle and lower disco-cellular nervules nearly straight and nearly upright, the lower rather 
longer than the middle ; second median nervule given off a short distance before the lower end of 
the cell ; submedian nervure straight. HINDWING, somewhat lengthened, usually furnished 
with a moderate-sized /ai/ at the termination of the first median nervule ; the tail, however, 
is reduced to a mere tooth in some species ; outer margin somewhat varying in outline ; in 
some species it is scalloped, in others oblique from the apex to the termination of the second 
subcostal nervule, thence to first median nervule straight, in others again it is evenly rounded 
throughout ; costal nervure much arched at base, terminating at the apex of the wing ; fist sab- 
costal nervule given off some little distance before the apex of the cell ; dzsco-celludar nervules 
straight and somewhat outwardly oblique, the upper a little shorter than the lower ; second 
median nervule given off a little before the lower end of the cell ; sabmedian nervure straight 5 
internal nervure recurved. Male with no secondary sexual characters. 
Although Z. seva differs considerably in outline and somewhat in style of markings 
from the other species of //erda, it has exactly the same neuration as has /. epicles, Godart, 
which is the type of the genus; in which therefore it is retained as a slightly aberrant 
species. 
Professor Westwood (Gen. Diurn. Lep., vol. ii, p. 482 (1852) describes the Jlerde as 
** beautiful Indian species with naked eyes, setose palpi, antenne with long joints ringed with 
on the underside, where they seem at first glance, extremely similar to phanicurus, Lederer, as on this side 
the hindwings are light yellow or ash-grey with red marginal spots. In the Persian casfius they are darker 
yellowish-brown with brownish marginal spots, which only very seldom turn into reddish. Also the underside 
of the forewings is in the variety ¢ransiens lighter grey, with more yellowish red on the outer part than in 
caspius.” (Staudinger, |, Cc.) 
* “ Chrysophanus susanus, n.sp. Hapirat : Gunduk, Biluchistan, June, 1885 ExpANSE : 1 inch, All'ed 
to C. phanicurus, Lederer. Uprrersipe. Both wings smoky brown, with the copper colour shewing through. 
Forewing paler than the hindwing, and of amore copper hue. oth wings darker towards the base, the few 
markings on the wings above caused by the markings below shewing through the wing. Forewing with 
three spots in the cell in a line, one being at each end and one in the middle ; costal margin and hinder 
margin deeper brown, and a band of the same colour on the outer margin. Hindwing witha faint submarginal 
band of reddish, clearer towards the anal angle; tail as ina C. phle@as, Linnzus, but long and produced like a 
* Hair-streak.. Head white with a brown centre, collar white ; eves and dody brown ; antenn@ brown with white 
bands. UNpersibe, doth wings coloured and marked somewhat as in A. panava, Westwood[ C. favana, Kollar], 
all the spots and lines black surrounded with whitish. /oewng pale copper yellow, fading to whitish at the base, 
three spots in a line in the cell, one in the interspace below, just underneath the centre cell spot, marginal line 
black, a submarginal macular band with a thinner macular line between, but not reaching the hinder margin, and 
a discal corresponding row of spots smaller than the submarginal row. AHindwing coloured and marked 
almost exactly as in C. fanava; two spots at the end of the cell ; and five rows oP apes and macular lines 
on the wing; subbasal row consisting of two spots; ante-medial row of four spots almost in a line, passing 
just inside the two spots at the end of the cell ; a curved row of discal spots ; a submarginal macular line ; a 
band of white between these rows ; another macular line close to the border line, which is also black with a red 
band between.” (Swinhoe, MS.) 
+ Heliophorus has fifteen years priority over //erda, but as the former name has never since it was invent- 
ed by Geyer for a species of this genus been used for the genus, I prefer to leave undisturbed the well-known 
name J//eda for this group of butterflies, ‘ .
