spots, the outer series speckled with metallic green scales. FEMALE. UPPERSIDE, both wings 
with blue basal and white discal areas, the discal areas black-spotted, the outer borders 
black and traversed by a more or less distinct row of slender white lunular marks which are 
single on the forewing and double and broadest on the hindwing.” UNDERSIDE, doth wings 
as in the male. 
** Note.—The markings on the underside of this species are wider and more broken up 
than in the allied North Indian form (7. za7a,* Kollar), and the female is more prominently 
white-marked on the upperside.” (JZoore, |. c. in Lep. Cey.) 
Fabricius in establishing the species in 1793, described only the female : but Godart in the 
Encyclopédie in 1823 described also the male, Dr. Horsfield in 1828 redescrited both sexes : 
but the India House Museum contained only one female specimen from the Mediterranean 
coast, this species not having been taken in Java by Dr. Horsfield. The term used by him for 
the colour of the underside macular streaks is ‘ater’: while he distinguishes the penultimate 
spot of the marginal series of the hindwing as ‘ ziger’—and ‘ pronounced black.’ 
** M. Lucas’ figure is not very characteristic. The species may readily be distinguished 
from 7. xara,* Kollar, of India by the break in the submarginal series of spots on the under- 
side of the hindwing, the spots towards the costa forming a line with those beyond the cell.” 
(Butler, 1. ce in Proc. Zool. Soc. Lond., 1884). I find this character to hold good in a single 
female specimen from Aden (Mr. Butler is writing about Aden butterflies) in my collection, 
but it does not exist in the four typical Algerian specimens I have described above. As I 
cannot find this character represented in any Indian specimen, and it does not occur (in some at 
any rate) North African examples, Mr, Butler may hereafter, perhaps, consider it a sufficient 
character on which to found a ‘‘ new species.” 
EG, pale apple-green with porcelain-white ridges and tubercles, the ridges arranged in 
lines parallel to or concentric with the equator, the tubercles arranged meridianally in curv- 
ed lines, so that the tubercles, when the egg is viewed from above, form a figure 
like a star of many rays all curved similarly and in the same direction. The tubercles appear 
very conspicuous under a microscope and are blunt conical, in size they are equal in diame- 
ter about to the intervals between them. The egg is very much flattened, and with a 
wide depression at its apex, it has in fact much the proportions of an Echinoid of 
the genus Diadema. The character of the sculpturing of this egg, as compared with 
that of Curetis thetys, Drury,is quite different. Larva, just half an inch in length when 
full-grown, much flattened, the head pale ochreous and completely hidden under the second 
segment, which is somewhat wide, the third and fourth segments progressively a little wider, 
whence the body very gradually tapers to the last segment, which is about as wide as the second. 
Colour pale green, the whole upper surface covered with a shagreening of small white 
tubercles, which under a magnifying glass give it a frosted appearance ; along the lateral edge 
of the body and round the anal segment there are numerous somewhat long whitish hairs. From 
the third to the anal segment there is a somewhat broad (slightly decreasing in width posteriorly) 
yellowish-green dorsal stripe, which bears a red stripe in its middle decreasingly on the 
first four segments on which it appears ; in some specimens the dorsal stripe is marked with 
reddish on both sides, which colour is very conspicuous on the twelfth and thirteenth segments. 
There is also a subdorsal series of small spots from the third to the eleventh segments inclusive, 
which are quite inconspicuous in some specimens. The extensile organs on the twelfth segment 
are small. The constrictions between the segments slight and inconspicuous, Dr. Lang 
says it feeds on “ Liziphus [? Zizyphus] vulgaris.” In India it eats the young leaves and 
flower buds of Zizyphus jujuba. Dr. A. Forel of Geneva identifies the ants which attend 
these larvae as “ Camponotus rubripes, Drury (sylvaticus, Fabricius), subspecies compressus, 
Fabricius ; and Pheidole latinoda, Roger.” PuPa, of the usual lyczenid shape ; head, thorax,’ 
and wing-cases green speckled thickly with black, abdomen green. There is an indistinct 
* How either Mr. Moore or Mr Butler can have ascertained that the underside spots and markings of Kollar’s 
T. nara were wide or narrow, continuous or macular, I am at a loss to understand, seeing that Kollar’s Latin and 
German descriptions give absolutely no information whatever ou these points,
