Etiella is represented by E. zinckenella, Treitschke. It is a common 
pest of cold weather pulses, and of sann hemp (Crotalaria), the bright, 
red or green larva feeding in the pods ; the little moth is grey, the costa 
white-edged, the forewing with a transverse ridge of raised scales near 
the base. It is often extremely abundant and does a considerable amount 
of damage to many varieties of pulse. 
Epipaschiince. —A small sub-family including seven genera of moth s 
approximating in appearance to the Bombycine type. The larvae live in 
colonies and form social cocoons. No species appear to be common in 
the plains. 
Chrysaugince. —A neotropical sub-family with two genera recorded 
in India, not found in the plains. 
Endotrichince. —Slender moths, forming nine Indian genera, distin¬ 
guished by the venation, not occurring in tropical India. 
Pyralince. —A sub-family of thirty genera, recorded almost wholly 
from hill localities. The character of the venation serves to distinguish 
the group, while the structure of the palpi, maxillary palpi and wings 
must be compared for the identification of genera. Pyraiis includes the 
pretty moth, Pyraiis farinalis , Linn., found commonly on walls of houses, 
whose larva feeds in oatmeal, potatoes and similar vegetable substances 
and is a cosmopolitan household pest. Hypsopygia mauritialis, Boisd., 
was reared from a caterpillar found at the roots of a Sissu tree ( Dalbergia 
sissu; Plate XLII, figs. 5, 6). It has since been found to live as a larva 
in the nests of Polistes hebrceus, feeding on the wax and destroying the 
larvae and pupae. 
Hydrocampince. —Slender moths, with long legs ; many species are 
common in the plains, and over thirty genera are recorded. Many more 
remain to be described. The larvae of some are aquatic, living actually 
in water and breathing by means of gills or at the surface and breathing 
air directly. 
Nymphula is universally distributed and common in India. The 
known larvae are aquatic, the body having tubular gills, with tracheal 
tubes in them, air being apparently obtained by transpiration through 
the thin gill-walls, and spiracles, though present, being closed and func¬ 
tionless. N. depunctalis, Guen. (Plate XLIX), is a common species,
