Originally ee from North Australia, this species has been reared , 
at Pusa from a larva mining leaves of Nepheliwm litchi(?). In August 1917 
quite appreciable damage was done at Pusa to the tender leaves of entillnien oh 
litcht hy the mining of this larva(?). 
The larva first of all bores into the midrib which develops a dusky red 
colour ; it begins somewhere near the base of the leaf and works towards the 
apex. As it goes forward it mines the blade of the leaf on both sides of the 
midrib, along the veins, producing a characteristic palmate dusky-red mine, 
as the entire mined portion develops a dusky-red colour. In bad cases of 
attack the whole leaf dries up. 
The full-grown larva is about 5 mm. long and about 0°75 mm. across the 
anterior part of the body which tapers slightly posteriorly, segments distinct, 
uniform green, fourth pair of prolegs absent. 
When full-fed, the larva leaves the mine and forms a round scale-like 
flat cocoon on the leaf or stem wherever a suitable cover or concavity is avail- 
able. In confinement cocoons were formed in the corners of the cage or by 
the side of the protuberant midrib of the leaf. The cocoon is almost trans- 
parent, so that the contained pupa is partly visible. 
The pupa is slender, cylindrical, about 4:3 mm, from head to anal extre- 
mity, beyond which the extremity of the leg-case extends for another 15 mm. 
and about 0°75 mm. broad, frons with a curved spine with which the pupa 
pierces the cocoon ; colour green at first, afterwards turning yellow-brown.
