THE ENTOMOLOGIST. 271 
eating: twelve or thirteen bites it took at the leaf to complete 
the curve; the last to see it at night and the earliest morning 
visitor found it feeding,—and on nothing but beech; the 
largest and juiciest leaves were daily put fresh into the cage ; 
oak was always there, but not touched. It grew rapidly, as 
one might expect, till the head, which seemed large out of 
all proportion, looked but a sorry balance for its enormous 
tail; in fact, the posterior segments seemed alinost too 
heavy to drag about; and on one occasion Fagi assumed a 
comical appearance by resting this imposing tail on a bed of 
moss, while it lost no time in eating as if for a wager. In the 
day-time the cage was kept out of doors; and if Fagi could 
be said to eat more greedily at one time than another, it was 
when the wind was so high as to blow the leaves about in the 
cage. 
Instead of being alarmed when disturbed it either continued 
placidly eating or else curved its tail over its back, and 
pugnaciously threw out its long legs, as if to resent the 
interference. A small larva of Orgyia fascelina was feeding 
in the same cage, and happened once to be resting on a twig 
too near to Fagi for its own comfort, for, coolly enough, Fagi 
struck at it with one of its long legs, and sent the unlucky 
Jarva to the floor of the cage. 
Fagi enjoyed life so thoroughly as a larva, it seemed as 
though it meant to remain one all its days; but on September 
19th its appetite failed, and the next morning had for the first 
time forsaken its food, and was sitting disconsolately on the 
floor of its cage. It soon set about seeking a suitable winter 
dwelling, and in its ramble (to show that its strength was in 
no way diminished) crawled under a small saucer, tolerably 
heavy with earth and moss. Presently it began to draw 
together a large beech leaf and an oak by little columns 
of white silk, and by evening the leaves were entirely closed ; 
so no more was to be seen of Fagi; and I wait for its 
appearance in another form next summer. 
Other larve in spinning move their heads to and fro 
between the two surfaces they wish to unite, carrying the 
silk in their months; but Fagi scarcely moved its head at all, 
guiding the silk from side to side by means of one of its legs. 
The operation was an interesting one. . 
Although in eating Fagi’s long legs seemed almost to be
