138 LIFE-HISTORIES OF GRACILLARIADA 
abdominal segments, together with the anal claspers. Pupation takes place 
inside the mine, in a white silken cocoon. Pupa about 2°5 mm. long, brown. 
A large proportion of the larve are parasitized. (Umrao Bahadur’s Cage- 
slip 20.) 
LITHOCOLLETIS VIRGULATA, MEYR. (PLATE XXXIV.) 
Inthocolletis virgulata, Meyr., B. J., XXIII, 118-119 (1914)(!), Exot. Micr., 
II, 5-6 (1916)(?). 
Originally described from Karwar, where it was bred from cocoons found 
on Ficus(*). : 
Reared at Pusa from “ larvee mining blotches on upper surface of leaves 
of Butea frondosa, pupating within the mine. This is normal for the genus 
and is doubtless correct, but does not accord with Mr. Maxwell’s account of 
the original specimens, bred from cocoons ‘ unusually large for the size of the 
moth’ found exposed on leaves of a tree at first stated to be a Ficus but 
this identification was subsequently withdrawn ; it seems likely that there 
must have been some error here, and that the moths did not really emerge 
from these cocoons ”. 
Mined leaves of Butea frondosa, containing larve and pupe, were found 
at Pusa on 22nd February 1916 and 11th March 1916. The mines are situated 
on the upper surface of the leaf. Pupation takes place within the mine in a 
thin cocoon woven beneath the epidermis of the leaf. A large proportion of 
the larve are parasitized by a small Hymenopteron, of which four to six 
grubs are found in each larva, these grubs pupating inside the body of the 
host which becomes twisted up like a rope (figure 2). (C. 8, Misra’s Cage-slip, 
dated 22nd February 1916.) 
LITHOCOLLETIS CONISTA, MEYR. (PLATE XXXV, FIG. 1.)

[description amended |(). 
Described from Pusa, where it was reared from larve mining leaves of 
Triumfetta neglecta (Tiliacez)('). 
Larvee were found at Pusa on 3rd June 1910 mining under the epidermis 
of the under surfaces of leaves of Triumfetta neglecta, Many larve feed in 
one leaf, each mining an area of about one-seventh to one-fifth of a square 
inch. The mines are of an irregular shape, usually bounded by the larger 
leaf-veins, as the larvee never cross such veins. The larve eat very little 
of the mesophyll substance and a newly-attacked leaf is hardly distinguishable
