larvee are able to leave their mines freely and, if a branch is disturbed, almost 
all the larvee leave their mines and walk about. 
The larva is about 3 mm. long, cylindrical, very slightly tapering poste- 
riorly, segments distinct, yellow, with thin scattered hairs ; head rounded, 
yellow ; prolegs only on third to fifth abdominal segments, together with the 
anal claspers. (Plate XLIII, fig. 5.) 
When full-fed the larva leaves the mine through a round hole bitten 
through the upper epidermis and twists another green leaflet into a cone to 
form a pupal chamber. It first of all turns up the tip of the leaflet and fixes 
its apex to one side of the upper surface of the leaf with silken threads ; it 
then bites three or four small holes near the edge of the leaflet near the rolled- 
up apex and a few more holes about one millimeter nearer the base and 
proceeds gradually to bend and twist the leaflet until the whole of it is rolled- 
up into a cone. (Plate XLIII, fig. 4.) Many of these cones may be 
formed close together and look like a row of small fruits hanging from the 
rachis. (Plate XLIII, fig. 3.) Inside the cone a thin white silken cocoon 
is formed and inside this the larva pupates, 
The pupa is about 2°5 to 3 mm. long, cylindrical, yellow. (Plate XLIII. 
fig. 2.) In some examples the antenna-case projects beyond the anal 
extremity, in others it barely projects. The pupa wriggles out of the cocoon 
to some extent before the moth emerges. 
The moth rests in the usual Gracillariad manner and waves its antenne 
about briskly. (Plate XLIII, fig. 1.) It occurs at Pusa from March to 
June and probably throughout the year.

Originally described from Australia, where it is recorded from Queens- 
land(® °). Also known to occur in the Kermadec Islands(* *) and in Africa(®). 
Within our limits it has been recorded from Pusa(*), the Khasi Hills(3), 
Darjiling(*), and North Coorg(’)._ We have it from Pusa, Lebong (Darjiling), 
and Bassein Fort (Bombay). 
The larva rolls the small leaves of Dalbergia sissu, forming a small mass 
of often dry leaves in which it lives and pupates. The pupa is sometimes in 
a web of very white glistening silk on a leaflet(7).
