324 LYCAENIDA. ILE RDA. 
EXPANSE : @, 1'2 to 1°33 $, 1°3 to 1°4 inches. 
DESCRIPTION: MALE, ‘f UPPERSIDE, 40h wings fuscous shot with violet. Hindwing 
tailed, a marginal dentate fulvous fascia. UNDERSIDE, bo/h wings cinereous, a common 
rufous fascia near the margin, outwardly dotted with black, inwardly margined with whitish. 
Hindwing with two black dots.” (Kollar, 1. c.) 
MALE. UPPERSIDE, both wings shining violet. Forewing with a well-defined rather 
broad outer black margin. Aindwing with the costa and outer margin rather broadly black, 
the latter bearing a prominent series of orange lunules enclosing rounded black spots, the 
last outwardly marked with fine bluish-white dots; an intensely black anteciliary line. 
UNDERSIDE, doth wings dull ochreous, a fine black anteciliary line. Forewing with a submar- 
ginal orange lunulated band from the first median nervule decreasing to the apex, inwardly 
defined by a narrow white lunular line, which latter is bounded on both sides by a fine black 
thread, a marginal series of oval black spots between the veins, the one in the submedian 
interspace very large, out of line, nearer the base of the wing. Aindwing with the outer 
margin similarly marked to that of the forewing but all the markings broader, the inner white 
band carried down the veins in sharp points towards the outer margin ; a prominent round black 
subcostal subbasal spot, and another near the middle of the submedian interspace ; ¢at/ black 
tipped with white ; cé//a throughout alternately black and white ; dody fuscous above, white 
beneath ; /egs white, outwardly fuscous. FEMALE. UPPERSIDE, doth wings dull fuscous, with 
no trace of the shining violet coloration present in the male ; the orange lunulated submarginal 
fascia on the hindwing as in the male, but more or less continued on to the forewing towards 
the anal angle, on the hindwing with a fine blue line following its inner margin, sometimes 
present in the male. UNDERSIDE, doth wings as in the male. 
Larva when about half-grown pale yellowish-greenish, the whole surface thickly 
shagreened and covered with rather long brownish bristly hairs, which are longer on the 
amterior and posterior segments and along the sides than elsewhere ; there is a narrow dark 
dorsal line, but no other markings. In shape the larva is about as high as broad, of very 
nearly equal breadth throughout, hardly tapering at either end, the fourth segment rather 
wider than the rest, the constrictions between the segments slight. The full-fed larva is 
just half an inch in length when walking, of the usual lyczenid shape, flattened, broader 
than high, both ends rounded, the segments (except the second and last) of almost equal 
breadth, the constrictions between the segments shallow, the whole larva pale dirty greenish 
mottled with dirty dull crimson, the narrow dorsal line also dull crimson, that being the only 
conspicuous marking possessed by the animal; the whole surface is covered with minute 
whitish dots, also with short fine brownish hairs, which are placed more thickly at the sides 
and on the posterior segment of the larva ; head entirely hidden as usual under the second 
segment, pale greenish, anteriorly becoming rather dark; all the legs also pale greenish. 
Feeds on a species of sorrel. Pupa exactly ‘4 of an inch in length, of the usual lycznid 
shape, bluntly rounded at both ends, the thorax slightly humped, a little constricted where it 
joins the first abdominal segment ; coloration pale greenish, profusely sprinkled with blackish, 
entirely without markings, the whole surface roughened, being covered with minute points, 
but not hairy. 
Iam indebted to Mr. P. W. Mackinnon for the two larvze and a pupa described above. 
He observed a female 7. seza ovipositing on sorrel leaves, and on searching found three larvze, 
one of which turned to a pupa on the long journey to me by post of 1,000 miles, occupying 
three days in transit. These specimens were obtained at Masuri, in the Western Himalayas, 
at 6,000 feet elevation early in March. Mr. Mackinnon assures me that ants do not attend 
this larva, and I was unable to find any extensile tubercles on the twelfth segment, or a mouth- 
like opening on the eleventh segment. Dr. G. King has kindly identified the food-plant for 
meas Rumex hastatus. 
T. sena is without doubt the commonest species of the genus in the Western Himalayas, 
occurring to the eastwards certainly as far as Kumaon, and from about 3,000 to 9,000 feet 
elevation. Mr, Moore records it from Darjiling, but this is probably a mistake. Mr. Doherty
