ASPILATES GILVARIA. 149 
length of its neighbour as they were placed in a 
slanting row. 
The newly hatched larva is very pale brown on the 
back and belly, with a dark brown subdorsa! line and 
a whitish stripe alone the spiracies. When the larva 
is about one-third of an inch long, its colour is for the 
most part pale ochreous, the back showing paler, with 
a fine dorsal line of brown; there is also a brown 
subdorsal line, followed at an interval by a broader 
purplish-brown stripe. After this, when the larva 
begins to grow, the ochreous tint becomes colder, and 
so continues till after the last moult. 
When full-grown the length 1s about one and a 
quarter inches, the figure rather slender, cylindrical, 
being stoutest at the tenth segment, and thence 
tapering almost imperceptibly to the head, which is 
nearly as wide as the second segment, and is flattened 
and narrowed a little infront; anal flap ending in two 
short points, whilst from under it projects a pair of 
longer and more slender points, shghtly curved in- 
wards, and projecting quite one-sixteenth of an inch; 
the skin smooth, but transversely wrinkled on the 
hinder part of each segment, and along the spiracles ; 
the larva when handled feels tough and stiff. Although 
the general colouring is pale ochreous, yet there are 
several lines and stripes to be distinguished, and the 
difficulty is to speak of these with sufficient clearness, 
and at the same time not give too strong an idea of 
them. The ground colour pale greyish-ochreous, with 
a pinkish tinge along the sides; a broad paler stripe 
down the back, having a brownish dark line through 
its middle, most distinct on the front segments, and 
being edged with a fine brown line; a broad, pale, 
ereyish-buff subdorsal stripe, beginning on the head, 
and continued to the extremity of the anal points, 
bordered above by a fine brown line; next a broad 
lateral stripe (or band), sprinkled closely with brown 
freckles, and bearing two fine pale lines, the lower of 
which is whitish throughout the four last sezments,
