SUB-FAM. SATYRINiE. 
1. GENUS LETHE (DEBIS). 
2. genus MYCALESIS (calysisme). 
3. genus MELANITIS. 
4. genus YPHTHIMA. 
The Sub-fam. has a universal distribution, but the above genera are restricted to the 
Oriental, Australian and Ethiopian Regions, and they are chiefly Oriental. Lethe and Melanitis 
are mainly crepuscular, Mycalesis much less so, whilst Yphthima is diurnal altogether in its habits. 
A conspicuous Satyrid feature is the subcostal nervure, which is much swollen or dilated at the 
base. The larvae of these genera are very sluggish, eating slowly and remaining motionless for long 
periods till just before pupation, when like all larvae they become restless. The foodplants of all 
the genera here represented are various grasses or reeds. 
Lethe europa, Fahr. 
Very common, but keeping to jungle and thickets, where towards evening it flits in and 
out with a swift and most erratic flight, the $ being fairly conspicuous from her broad white bands 
in the forewings. It is especially attached to bamboo clumps, and fond of threading its way through 
the mazes of scrub and jungle, sometimes settling very suddenly with closed wings, often on the 
underside of a leaf, occasionally on the ground; sometimes two or three toy together over the 
bamboo tops. It is not fond of flowers, but sips the exuding juices of trees, particularly the sap of 
bamboo shoots, where it may frequently be seen during the day, in company with Hemiptera and 
beetles, all very intent on sucking up the gum or sap. It is also fond of overripe Lantana berries 
and other fruits. The $ when engaged in laying may be seen flying at any hour of the day, whilst 
the £ usually avoids broad daylight. The ground colour on the upperside of both sexes is sometimes 
very light compared to its usual tint, becoming ochreous. 
Fig. 7, PL II is from a $ taken in October, Fig. 8 from a £ taken in July. This butterfly 
varies little, if at all, seasonally; the pale forms being found irrespective of the time of year, for it is 
on the wing every month, though most numerous in autumn. 
Egg, globular, smooth, pale green; laid singly on the underside of a bamboo leaf, the 
foodplant of the larva. It does not feed, so far as I can find, on the tall bamboo used for scaffolding 
and carrying-poles ; nor on the sp. with the very large, broad leaves, but on the bushy, much-branched 
and often thorny varieties. 
Larva, figured on PL ia, Fig. 11, pupa Fig. 12. Just hatched the larva is entirely white, 
head included. The two parts of the cleft posterior of this larva are usually kept close together, so 
that they appear like one stout horn. This is also the case with other Satyrid larvae. 
The parts coloured yellow in the figure of the pupa are gilt.
