BOARMIA CINCTARIA. Md) 
The larve hatched on May 28th, and at first they 
were dark olive-brown, with pale olive-green head, a 
whitish stripe along the back, another along the side ; 
several kinds of food were given them, but they un- 
mistakably preferred birch, on which, after wandering 
over other leaves, most of them settled down, and 
began to eat minute patches of cuticle from the 
under side, causing transparent specks to appear on 
the upper surface of the leaves. By the 3rd of June 
some had escaped, probably during my previous in- 
spection, and one had died on an oak-leaf; the 
remaining twelve had moulted, and were pale greenish- 
yellow on the back, with a very broad darker greenish 
stripe on each side. After another moult, by the 9th, 
they were a quarter of an inch long, of olive-green 
colour, with several fine, equidistant, double, longi- 
tudinal, darker lines; at this time they were very 
lively active loopers, and had been apparently feeding 
a little on oak as well as birch, but preferring the 
latter. By the 12th they were five-sixteenths of an 
inch long, and much paler green in colour, with lines 
only just visible, and by the 15th had again moulted 
and become darker, and on the 18th were nine- 
sixteenths of an inch long, having distinct dark lines 
with the addition of pale subdorsal stripes; by the 
23rd the most forward individuals had increased 
their length to three-quarters of an inch, and were 
stouter in proportion, their lines still more distinct, 
the subdorsal white stripe relieved now by a specially 
dark one beneath. 
By the lst of July they had moulted for the last 
time, and in the course of three or four more days 
attained their utmost dimensions, becoming full-fed 
and returning to earth from July 6th to 10th. 
The first moth came forth on April 25th, 1877, 
simultaneously with about a dozen of (Mcophora 
pseudospretella, both species continuing to appear at 
intervals, and the last specimen of B. cinctaria on 
May 12th, in all seven males and three females, a
