LEPIDOPTERA. 
Callidulim:. 
A precostal spur to vein 8 of hindwing which is curved and approxi¬ 
mated, or anastomosing with, or connected to 7 by a bar. 
Vein 1 c. absent. Forewing vein 5 nearer 4 than 6. 
These are day-flying moths of medium size with simple antennae 
and long palpi; six species are known from the hills, none in the 
plains. 
Drepanid#:. 
Hindwing, vein 1 a absent or reduced, no precostal spur to vein 
8, which is curved and anastomoses with , or approximated 
to, 7, or is connected by a bar ; vein 1 c. absent. 
Forewing vein 5 nearer 4 than 6. 
These are small moths of slender build with the wing apex often 
produced ; the wings are large, the palpi slender and the antennae simple 
or pectinate in the male. Nearly all are hill forms and are not met with 
in the plains. The larva is bare, the anal prolegs absent, the body ending 
in a long process and having humps on the segments. The pupa is found 
in a cocoon among leaves. (Hampson.) The Fauna lists 65 species 
and 14 have been since added by Warner, Sw inhoe and Dudgeon from 
the Himalayas and Khasis. These moths are found almost wholly in 
subtropical India, only one being known to breed in the plains, though 
others are very occasionally captured near forest areas. They are not 
uncommon in hill forest areas and are one of the families so character¬ 
istic of the subtropial zone of insect life in India. Phalacra vidhisara, 
Wlk., is a small reddish-brown moth whose larva feeds on the toddy 
palm (Phoenix sylvestris). It is a broad larva, green with four rows of 
pink processes bearing spines, lying on four green ridges which are 
connected by cross ridges ; between these are purple spots; the head is 
retractile. The larva is slow and inactive, feeding on the leaf. This 
insect occurs rarely in the moister parts of India. Or eta extensa, Wlk., 
is more widely spread, a brilliant yellow moth with the forewing drawn 
out at the apex.
