and spins a band or belt round the middle of the body, 
exactly in the same manner as the Pieride among the 
butterflies. 
The pupa varies from half to three-quarters of an 
inch in length, and is of the usual Hphyra shape and 
position. Head square and blunt, and from it the 
body is attenuated gradually and evenly to the anal 
point; the front and back are rounded, but are dis- 
tinctly divided by a lateral ridge, which extends a 
little beyond the head on each side, forming two short 
blunt points; the back is also slightly arched. Ground 
colour of the pupa greyish-white, with the leg- and 
wing-cases veined with smoke-colour; there is a pale 
erey longitudinal line through the centre of the back, 
and on each side of it a series of black dots. 
Two imagos emerged about the middle of August ; 
the remainder of the pupz stood over until spring.

HEPHYRA PENDULARIA. 
Plate CXV, fig. 10. 
In August, 1872, I beat rather commonly from 
birch, in Sherwood Forest, two very distinct varieties 
of the larva of this species, and am not aware that a 
description of either of them has been published. 
Length rather over an inch, and slender; the head 
small, the same width as the second, but narrower 
than the third segment; it has the face flattened, and 
is notched on the crown. Body of tolerably uniform 
bulk, attenuated slightly from the posterior to the 
third segment, which is swollen laterally. The skin 
has a very slightly puckered appearance, and the 
seements overlap each other, rendering the divisions 
conspicuous. 
Var. 1 has the ground colour pinkish-purple, in 
some specimens greyish-purple; head dark sienna- 
brown, the mouth, and a line down each side the
