Balmuto, Kirkcaldy, N.B., June 1, 1875. 
[Mr. Doubleday, also, in a private letter dated 3rd June, 
says that it feeds in Park Hall Woods on hornbeam, birch, 
sallow, aspen, &c.; and in his own garden, at Epping, on 
plum, apple, whitethorn, rose, &c. In this matter I have 
made a palpable and inexcusable blunder, but it arose from 
infirmity of memory and haste rather than ignorance. In 
an old number of the old series of the ‘ Zoologist,’ I have told 
the marvellous life-history of this moth, and I think for the 
first time in this country; but as my observations have not 
hitherto appeared in the ‘ Entomologist,’ I hope I shall be 
excused for the decided egotism implied in reprinting my 
own lucubrations: it will be seen that so far from giving oak 
as the only food-plant of Pilosaria, I have omitted the forest 
monarch altogether.—Edeard Newman. | 
Description of the Larva of Phigalia pilosaria.—The 
eggs are laid in crevices of the bark of Carpinus betulus 
(hornbeam), and some other forest trees, very early in the 
spring, and are hatched before the leaves begin to expand. 
The young larve find their way to the buds, and continue to 
feed on these until the leaves expand, previously to which 
they grow very slowly, but no sooner are young leaves 
available than the larve feed on them voraciously, and are 
full fed by the end of May or beginning of June, when they 
rest in a nearly straight position, but with the back slightly 
arched; they neither fall off the food-plant nor feign death 
when disturbed. The head is prone, of less circumference 
than the body, and notched on the crown. Body of uniform 
circumference, beset with numerous conspicuous warts, 
scarcely amounting to humps; each of these warts emits a 
strong, but short bristle, which terminates in an extremely 
fine point: the situation of the warts I will describe :—On the 
2nd, 3rd and 4th segments they are small and insignificant; 
on the 5th segment are two placed transversely on the back, 
and one on each side, but these are still inconspicuous, 
although manifestly larger than those on the preceding 
segments; on the 6th and 7th segments, in the same position, 
are two dorsal and two lateral warts, all much larger; the 
same number and arrangement of warts obtains on the 8th, 
9th, 10th and 11th segments, but all these are small, as 
on the 5th segment; on all these segments, that is,
