160 ANISOPTERYX AESCULARIA. 
looks like a little knob of earth; it is about three- 
elghths of an inch long, and a quarter of an inch broad. 
The pupa is rather over five-sixteenths of an inch 
long, very plump and full, being for the greater part 
of its length nearly an eighth of an inch across; the 
eye-cases prominent, the abdomen tapering off quickly, 
but with a blunt end, on which is a flat blackish knob, 
furnished with two short widely diverging sharp 
spines; the colour golden-brown, tinged with greenish 
on the back; the eye-cases, etc., more brown; the skin 
finely punctured, but glossy. (John Hellins, Sep- 
tember 11th, 1877; E.M.M., October, 1877, XIV, 113.) 
CHEIMATOBIA BRUMATA.

Once more I have looked at and figured this ubiqui- 
tous larva of the month of May, and again noticed the 
variations of the ground colouring, but that the lines 
of yellow more or less pale are constant in their 
arrangement, and that the spiracles are red of a 
brownish kind, and always situated actually on the 
yellow line where itis widest. (William Buckler, 1881 ; 
Note Book IV, 12.) 
CHEIMATOBIA BOREATA. 
Plate CXXVI, fig. 3. 
Two or three full-grown larve on birch were sent 
me on the Sth of June, 1881, by the Rev. J. Hellins, 
and they have again shown me how distinct this larva 
is from its congener, C. brwmata. For not only is the 
proportion more thick and stumpy, and the head 
more or less black in C. boreata, but the spiracles are 
black and just above the yellow line, and the anterior 
legs are also black. These are good distinctions, that
