larva does not feed upon nut, as stated by Stephens, Stainton, 
and Newman (copied, I fear, from some other author), but on 
the dwarf sallow; the eggs are deposited in July upon the twigs 
of the sallow, but do not hatch until the following May; at 
the end of June the larva changes to a pupa in a slight web 
between the leaves of the food-plant, the perfect insect 
emerging on or about the festival of St. Swithin. 
Round the heads of the pine trees I have mentioned, 
circled clouds of Fidonia piniaria; and on the boles are 
found Lithosia helvola, Ellopia fasciaria, Tephrosia punctu- 
laria, Acidalia inornata, Macaria liturata, Thera firmaria, 
Scotosia undulata, and many commoner species. The York 
specimens of Helvola are much larger than any I have seen 
from the South of England; the female is bright yellow, 
at first sight looking almost like Quadra, without the black 
spots of that species: it is a well-marked variety ; possibly a 
distinct species. 
Vipers abound on the moor, and two were killed; one of 
them measured two feet in length. A nightjar’s apology for a 
nest, with two eggs, and a fully-fledged young sparrew hawk, 
over which Mr. Carrington cleverly put his net, were amongst 
the miscellaneous captures of the day. 
A visit to the moor at dusk produced Lithosia mesomella, 
Acidalia inornata, Aspilates  strigillaria, Pempelia palum- 
bella, Crambus margaritellus. 
It is wandering too far from the subjects to which the 
magazine is devoted to mention that the ground, over which 
the day’s ramble extended, is that which witnessed the defeat 
of Halfagar, king of Norway, by Harold, on the eve of the 
Norman Conquest, at the Battle of Stamford Bridge, whence 
he led his gallant but disabled army to its doom at Hastings. 
It is 800 years ago; but what Englishman can look unmoved 
upon the scene of Harold’s victory? The aspect of the field 
of battle is probably but little changed; the Derwent flows 
through a richly-wooded valley ; there is a picturesque pointed 
bridge of great antiquity, and an old corn-mill by the water- 
side, with a little village clustered round it, much the sort of 
thing we may suppose to have existed here in Anglo-Saxon 
times; and somewhere near is the Northman’s grave, that 
“six feet of English soil, or more, if his stature required it,” 
which were the only terms Harold had to offer the invader.
