170 LIFE-HISTORIES OF PLUTELLIDZ 
~ so that it can live and feed hidden under this webbing. (Figs. a, b.) The larva 
is about 4 mm. long and about 0°75 mm. broad, cylindrical, creamy white ; 
head yellow, shiny, somewhat retractile into prothorax ; prothorax with an 
indistinctly chitimized integument ; prolegs minute, five pairs present. The 
moths emerged between 24th November 1916 and 15th February 1917. 
AMPHITHERIDA. 
This family has been established by Mr. Meyrick (Exotic Micr., 1, 154 ; 
Dec. 1913), to contain a small group of species developed from the Plutellide. 
The only Indian genera are Agriothera and Telethera, whose early stages are 
unknown.

This cosmopolitan species occurs throughout the world everywhere that 
man plants cabbages. Jt is abundant throughout our limits. 
The eggs are laid singly on leaves. The full-grown caterpillar is about 
8 mm. long, moderately stout, attenuated at each extremity, smooth, with 
short scattered bristly hairs; in colour pale-green with a pale-brown head 
and prothoracic shield. Pupa in a slight silken cocoon of open net-like 
texture; pupal period about ten days. On cabbage, cauliflower, radish, 
mustard and other eruciferous plants, the larva eating holes im the leaf(!®).
