crown the keels and ribs form a network pattern. When 
first laid, the egg is pale yellow and gradually changes to 
pearl-white. When about four days old it is mottled and 
zoned with rusty-red ; these markings gradually deepen in 
colour until they become drab-brown. The egg state lasts 
about twenty days. 
Larva. The young larva makes its exit by eating the crown 
of the egg and after hatching, it feeds on part of the empty 
shell. 
When fully grown after the fourth moult, the larva measures 
23 mm. long ; it is slug-shaped, tapering at each end. The 
head is bi-lobed, ochreous, and slightly speckled with brown. 
The ground colour is pale greenish-ochreous, and there is an 
olive-black medio-dorsal stripe, also a sub-dorsal wavy stripe 
of claret-coloured markings, bordered below by a pale band, 
then a broad irrorated band of claret-coloured markings, 
bounded by a band of darker colour, bordering the whitish 
lateral band, which is divided by a fine. claret-coloured 
line. The under surface is ochreous. The entire body and 
head are covered with whitish, serrated bristles with 
pronged points and bulbous bases ; the surface is granu¬ 
lated. In different specimens the ground colour varies 
in the amount of green, some are quite of a greenish 
hue, while others are more or less ochreous ; the develop¬ 
ment of the markings also varies. The larva is very slug¬ 
gish in its movements ; during the day it rests at the base of 
the grass stems, and feeds only at night. The larval state 
lasts about 240 days. 
Pupa. The pupa varies from 11 mm. to 127 mm. long, 
and is stout in proportion. The head is slightly beaked, 
the thorax swollen and the waist sunken. The abdomen is 
curved and the anal segments are embedded in the larval 
skin, and it remains firmly attached to the cremaster, which 
is without hooks. The wings are bulging. The ground 
colour is pale creamy-drab, and ochreous in the middle of 
the abdomen ; in some specimens the head and thorax are 
inclining to greyish. It is streaked and blotched with brown 
and black, the chief markings are on the wings, forming 
longitudinal streaks, and a bold stripe runs along the inner 
margin ; on the thorax and abdomen is a sub-dorsal series
