considerably dilated posteriorly, costa towards apex gently arched, 

 apex rounded-obtuse, termen little oblique, slight^ rounded ; 

 ochreous-orange, slightly violet-tinged ; about 18 — 24 white spots, 

 viz., three large transverse ones and two or three small on dorsum, 

 three more or less large rounded ones and two or three small in 

 disc, one rather large transverse on termen above tornus, and the 

 rest small, rounded, scattered along costa and towards apex : 

 cilia whitish, base ochreous-orange. Hind wings grey, thinly scaled 

 and sub-hyaline towards base ; cilia whitish, base grey. 



One specimen at base of Dawna Hills, Lower Burma, in March ; 

 and I possess three others from the island of Penang, and Labuan, 

 Borneo. 



TlNEID^. 



Tischeria ptarmica, sp. nov. 



cr' ? . 4-5 mm. Head, palpi, and antennas light greyish- 

 ochreous. Thorax greyish-ochreous sprinkled with fuscous. Abdo- 

 men grey, apex greyish-ochreous. Fore wings lanceolate ; 6 present ; 

 light greyish-ochreous irrorated with fuscous, with some scattered 

 dark fuscous scales, on dorsal half more or less 5^ello wish-tinged ; 

 undefined dorsal spots of dark fuscous irroration at middle, |-, 

 and apex : cilia pale greyish. Hind wings and cilia pale greyish. 



Bred in plenty from larvae mining small elongate blotches in 

 leaves of Zizyphus jujuba, at Puri, Orissa, in January. The species 

 occurred in great profusion, leaves an inch in diameter containing 

 twenty or more larvae, and the moths are described as ' ' swarming 

 like a cloud of midges round the tree." The mine, larval habits, 

 and pupa are similar to those of European species. 



Crypsithyris spelcBu, sp. nov. 



cf 9 . 9-10 mm. Wholly pale whitish-ochreous except eyes, 

 which are deep black. Fore wings elongate, narrow, costa gentl}^ 

 arched, apex pointed, termen extremely obliquely rounded. Hind 

 wings with transverse vein present, 2 — 7 separate. 



Khayon ('' Farm") Cave, Moulmein, Burma, in March ; three 

 specimens. This is a very curious and interesting species, appar- 

 ently a true cave-dweller, found permanently resident " in total 

 darkness " (Annandale), being the only known species of Lepidoptera 

 adapted to such conditions ; but since the eyes are fully developed 

 and the power of flight maintained, it would seem probable that the 

 darkness is not quite absolute, but such that eyes accustomed to it 

 can still perceive faintly. The absence of light has, however, suf- 

 ficed to prevent the development of colour, the insects being prac- 

 ticall}^ bleached or colourless. The larvae of four Indian species 

 of Crypsithyris are known, and all are lichen-feeders, so that prob- 

 ably this may feed the same way, in portable cases on the rock- 

 walls. Other Indian caves should be examined for similar species.
