170 LYCANIDA. LAMPIDES. 
In Java Dr. Horsfield records the larva as feeding on Butea frondosa, From Ceylon Mr. 
Moore describes the larva as “ onisciform; green or violet-brown, with a dark dorsal and 
lateral black lines. Pupa pale violet-brown.” 
. Little need be said about the occurrence of this common butterfly in India. Colonel Lang 
records it from Almora, 5,500 feet, which is probably the highest altitude it reaches in the Hima- 
layas. It is found almost everywhere except in the desert regions of Sind, and is probably coms 
mon everywhere where it occurs. Mr. G. F. Hampson notes that in the Nilgiri Hills “ the dry- 
season brood of Z. e/ianus, Fabricius, is much paler than the wet-season brood.” Colonel Lang 
writes on the same subject “ How very different are the two broods, the Summer and autumn, 
wet and dry season! They look marvellously distinct both on the wing and in the cabinet.”

DEscrIPTION : *‘ Allied to Z. @lianus, Fabricius, Z, celerio, Fabricius, and Z. agnata, 
Druce. MALE. UPprRSIDE, doth wings of the same pale-bluish tint as in the above-named 
species. Forewing entirely without any trace of a black border tothe exterior margin, 
whereas in each of the above species there is a decided black marginal band decreasing 
in width from the apex. UNDERSIDE, doth wings of a similar colour as in the above species, 
but of a darker tint than in Z. @lianus ; markings also similar, but more strongly defined. 
Forewing in several specimens without a marginal border. Hindwing, subanal spot with a 
much broader red inner border. FEMALE. UPPERSIDE, forewimg with the marginal black 
band narrower than in Z. @/ianus, the inner edge of the band curved like that in Z. alexis, Stoll, 
Hindwing with a narrower series of marginal lunular spots.” (JAZoore, 1. c.) 
In the Indian Museum, Calcutta, are three males and one female of this species, 
which include the type specimens, from Mergui. I also possess a single male, taken at Terria 
Ghat in Assam in the autumn, which agrees with the Mergui specimens. Mr. Moore says 
that this species has no trace of a black border to the outer margin of the forewing on the 
upperside of the male. There is, however, a very distinct anteciliary black thread, and this 
thread, being of equal width throughout both wings, not expanded into a more or less 
broad black border in the forewing, constitutes the best character, as far as I can see, for 
distinguishing Z. pura. I do not understand Mr, Moore’s remark that the underside 
of the forewing in several specimens has no marginal border. The five Mergui speci- 
mens I have before me agree precisely in markings on the underside, one with another, 
and also with many specimens of JZ. @lianus. The arrangement of the four characteris- 
tic strice is similar to that of many Z. @/ianus. In all the five specimens above mentioned 
the arrangement is identical. Nos. 1 and 3 cross the wing uninterruptedly from the costa to 
the inner margin, no. 3 is very slightly dislocated on the second median nervule, the lower por- 
tion more or less slightly shifted towards the base: nos. 2 and 4 end on the third and second 
median nervules respectively; and, as no. 2 is inclined slightly outwards towards no. 3, 
it meets or nearly meets this stria at the point of dislocation, thus forming with it a distinct 
Y, intermediate between nos. 1 and 4. It remains to be seen, from larger series collected 
in and near Mergui, if the Tenasserim form is perfectly constant in this arrangement of 
the four striae, nos. 2 and 3 forming a distinct Y between the straight nos. 1 and 4 striae, 
and also in the extreme fineness and uniformity of width of the marginal border of the 
forewing on the upperside in the male. These at the best are but very slight characters by 
which to separate this as a distinct form from the variable Z. elianus, 
Dry-season fornt. 
In the Indian Museum, Calcutta, are six males and two females of a Zampides taken in 
November and January in the Chittagong Hill Tracts by the late Mr, H. M, Parish, which I
