198 THE ENTOMOLOGIST. 
for the opportunity of doing so I have to thank Mr. John 
Harrison, of Barnsley, who gave me a dozen larve on the 4th 
of September, 1875; and further sent me a supply of eggs on 
the 19th of July last. The egg is large for the size of the 
moth, is oblong-square, with the edges rounded, and 
considerably depressed on the upper side; the colour at first 
pink, afterwards olive-brown. The young larve fed, but grew 
slowly, on knotgrass until autumn, when they ceased feeding, 
and remained rigid on the sides of the cage or on bits of 
stick, &c., through the winter, and well into the snmmer of 
the present year; as, at the time in spring when most other 
hybernating larvee were waking up, they persistently refused 
to show any signs of vitality beyond moving the front portion 
of the body backwards and forwards when touched. At this 
lime they were about five-eighths of an inch in length, and 
were about the most soberly-attired larve I ever had, being 
in colour almost uniformly very dark dull brown (almost black 
in some specimens), and with the exception of a still darker 
double dorsal line, and being a little paler at the segmental 
divisions, there was no other colour or marking. The latter 
part of May having arrived, and finding they did not seem 
disposed to avail themselves of the various kinds of plants I 
endeavoured to induce them to accept as food, including 
Plantago major, Anemone nemorosa, &c., besides the Poly- 
gonum aviculare, I took them up into a warm room, and 
again gave them a plentiful and varied supply of provender. 
Here J had soon the satisfaction of finding that one of them 
had evidently set to work with a will, again on Polygonum 
aviculare, and by the Ist of July it was full grown, when L 
described it as follows:—Length three-quarters of an inch; 
can scarcely be called slender, though not stout; head the 
same width as the 2nd segment; it has the face flat, and is 
distinctly notched on the crown; body somewhat flat when 
viewed from above, but rounded ventrally ; the 9th segment 
is the widest, and from it each becomes narrower to the head; 
the four posterior segments are of nearly uniform width, and 
about as wide as the 6th; the segments overlap each other 
considerably, rendering the divisions distinct, and also forming 
on each side a conspicuous lateral ridge; the skin is ribbed 
transversely throughout, and has a tough wiry appearance; in 
shape and habits it bears a very strong resemblance to many
