162 LIFE-HISTORIES OF GRACILLARIADE 
Occurs commonly at Pusa and Coimbatore, mining in leaves of Cajanus 
indicus(?) and Dolichos lablab(?). 
Reh This species has been found at Pusa on numerous occasions, mining the 
leaves of Dolichos lablab, Vicia faba, Phaseolus mungo, and Vigna catjang from 
below the epidermal layer which turns brown or brownish-white. The mine 
starts as a narrow irregular line but later on widens into a broad blotch which 
i Shows up prominently on the leaf. (Plate XLII.) The larva is about 4 or 
5 mm. long, rather flattened, segments sharply defined and slightly protrud- 
ing laterally, tapering posteriorly from thoracic region, uniform reddish- 
brown, the green contents of the alimentary canal visible along the length 
of .the body, and with a red submedian stripe ; head flattened, smaller than 
prothorax, light brown ; legs and prolegs well developed, reddish-brown ; 
prolegs only on third to fifth abdominal segments, together with the 
anal claspers. When full-fed, the larva emerges from the mine and 
pupates in a white silken cocoon afforded by the folding of any portion or 
by the side of a protruding leaf-vein. The pupa wriggles out through one 
end of the cocoon before the moth emerges and the empty pupa-case is 
left protruding from the cocoon. The pupa is about 3°5 mm. long, pale 
yellow, eyes red, wings and last two abdominal segments whitish-yellow.

Acrocercops acidula, Meyr., E. M. M., XLVII, 213 (Sept. 1911)(?).

Described from Pusa(!). Larva on Albizzia  stipulata (Leguminose)('). 
‘““Mr. Fletcher informs me that the larva mines leaves of Phyllanthus 
emblica (Euphorbiacee), not of Albizzia as originally stated through a mistaken 
identification of a native name ’’(’). 
This species is abundant at Pusa, the larvae mining in the leaflets of 
compound leaves of amlak (Phyllanthus emblica). The larva mines a part or 
a whole of a leaflet, usually on the under surface but also on the upper surface 
of the leaf, which turns pale brown or deep brown where mined. The mine 
usually commences near the apex of a leaflet as a narrow sinuous line which 
expands into an elongate blotch towards the base of the leaflet. (Plate XLII, 
fig. 7.) The upper epidermis is completely separated from the lower, 
the intervening space being filled with blackish pellets of excrement. The
