176 LIFE-HISTORIES OF LYONETIADA 
Larve were found at Pusa on 12th March 1916 eating holes in leaves of 
Trewia nudiflora, feeding on one side of the epidermal and mesophyll tissue. 
The larva is about 4 mm. long and 0°75 mm. broad, cylindrical, tapering 
slightly towards either extremity, segments distinct, pale greyish green ; head 
much smaller than prothorax, pale yellowish with a slight green tinge ; pro- 
thorax with a horny plate ; short scattered pale greenish hairs on segments ; 
five pairs of prolegs. Pupation takes place in a thin white silken cocoon 
attached to leaves or the sides of the cage. The pupal period is five or six 
days in March. (Tahl Ram’s Cage-slip 156.)

Described from Gorakhpur and Dalsing Serai in Bihar(} *), 
Larva on top-shoots of indigo. ‘ The larva is about 4°5 mm. long and 
about 0°75 mm. across the middle of the body which tapers towards each 
extremity ; the segments are distinctly separated by deep constrictions ; 
shape flattened; head flat, yellow, somewhat elongate, smaller than pro- 
thorax ; colour uniform dirty white; thoracic legs and five pairs of prolegs 
greyish. 
“The larva covers the top-shoots with a profuse web of fine white silk 
under cover of which it lives and nibbles small portions of the leaf-surface. 
It is often seen to walk over the webbing. When full-fed it spins a pufe-white 
somewhat elongated cocoon in any suitable situation which provides some 
corner, ¢.g., along the midrib on the upper surface of a leaf or in a rolled or 
folded leaflet. The moth emerges after about a week and rests with the 
anterior half of the body well raised and the antenne held extended at right 
angles to the body ”’(?).

Life, p. 540 (1909)(?). 
Described from Colombo, Puri in Orissa, and Pusa(!). 
Bred at Pusa in March from larve feeding in dry stems of Polypodium 
quercifolium(!). Larve found in January, reducing the stems to a mass of 
frass and dust amongst which the full-grown larve pupate in white silken 
cocoons, covered with frass and dust. Moths emerged from Ist January to 
11th March(?).
