face is covered with white, raised reticulations, forming an 
irregular network pattern, which increases in size on the side 
and develops into a beautiful network design of triangular 
cells. The reticulations rise into knobs at each angle ; the 
pattern decreases and finally disappears on reaching the base, 
which is smooth and rather concave. The ground colour is 
pale greenish-grey, the reticulations white and glassy. The 
egg state lasts nine days. 
Larva. The little larva emerges from the egg by eating 
away the crown. As soon as hatched, it crawls to the under 
surface of the leaflet and feeds on the cuticle. 
When fully grown, after the fourth moult, the larva is 
1270 mm. long and of the usual onisciform shape. The first 
segment is compressed and projecting; the segments are 
humped on the back from the second to the ninth inclusive, 
each side of the slight dorsal furrow, they are then sloping 
and compressed at the anal segment. On the tenth segment 
is a transverse honey gland, and a retractile tubercle on each 
side of the eleventh segment. The sides are flat and sloping to 
the dilated lateral ridge. The whole surface is finely granular 
and covered with white serrated hairs, longest on the dorsal 
humps and the dilated lateral ridge, where they form a pro¬ 
jecting fringe surrounding the larva. Also, minute lenticles 
are scattered over the body. On the first segment is a whitish- 
green dorsal disc. The head is very small, black and shining, 
and is withdrawn into the first segment and hidden while at 
rest. The normal colour of the larva is a rich brilliant green, 
with a darker green longitudinal dorsal stripe and a greenish- 
white lateral stripe ; the spiracles are white. In certain lights 
there are indications of very indistinct sub-dorsal stripes. 
The purity of the green varies in different individuals. 
Larvae that feed up and pupate in the summer exist for about 
45 days, while those that hibernate live for about 270 days. 
Pupa. The average length of the pupa is between 9 mm. 
and 10 mm. The head is rounded and the thorax is swollen 
and sunken at the waist. The abdomen is rounded and curving 
to the anal segment, which is embedded in the cast larval skin. 
The colouring of the head is ochreous-buff; the thorax is 
green ; the abdomen greenish ; the wings pale ochreous 
shading into greenish at the base. The entire surface is
