the upper cuticle, which forms a cover on the one side and 
the web on the other. 
When about twenty-five days old, and fully grown, after 
the fourth moult, the larva measures 28*6 mm. long. It is 
of almost uniform thickness. There are seven longitudinal 
rows of spines commencing on the second segment ; the first 
segment is spineless. The colour of the spines varies in 
different specimens ; in some they are wholly pale-yellow, 
in others black with yellow centres. The body is velvety- 
black, and leaden-grey at the sub-divisions ; it is densely 
sprinkled with minute white dots, each bearing a fine white 
hair. A longitudinal lateral lemon-yellow stripe, forming a 
series of crescents, ornaments the side, commencing on the 
fourth segment and ending on the eleventh segment. The 
ventral surface is coppery-brown ; the legs and claspers are 
deep tawny. The head is black, deeply sunken between the 
lobes ; it is studded with black warts, each emitting a hair ; 
some black and others whitish. Down the middle of the 
back is a double light-coloured stripe formed of cream-coloured 
freckles densely crowded together. 
The larva is a voracious feeder and continues feeding for 
an hour or more at a time. It appears to take no notice of 
being disturbed, as it remains feeding when touched. Only 
the stronger spines and stems are rejected, the whole of the 
leaf being consumed. The young larva lives under the pro¬ 
tection of a web until the third moult and remains solitary 
throughout all its stages. The larval state lasts about twenty- 
seven days. 
Pupa. The pupa is elegantly proportioned and measures 
24 mm. in length. The head is almost square, with only 
slight points, when viewed dorsally. Lateral View . The head 
is conical and rises from the apex in almost a straight line to 
the central angular thoracic point. The pupa is sunken at 
the base of the abdomen, which is swollen in the middle and 
curves to the extremity of a rather long cremaster furnished 
with hooks. 
The colouring is variable. Some are beautifully washed 
with golden and coppery reflections over the whole surface, 
showing only faint traces of markings, the principal being a 
lateral abdominal streak. Normal specimens have a ground
