162 THE ENTOMOLOGIST. 
three years I have searched in vain for it: I am ata loss to 
account for its sudden disappearance. Latterly cows have 
been turned into the meadow. Is it possible that they have 
destroyed the pupse?—Joseph Anderson, jun.; Alresford, 
Hants. 
Variety of Pieris Rape (Entom. vii. 140).—The yellow 
variety of P. Rapz is far from uncommon; I take it frequently 
here. I think myself itis a food variation, due to the larve 
having fed on turnips, as almost all the specimens I have 
were found flying over turnip-fields. I have, however, never 
taken it except in the autumn.—W. Douglas Robinson- 
Douglas ; Orchardton, Castle Douglas, June 12, 1874. 
Pieris Napi. —Early in May I took a pretty specimen of 
P. Napi, with under hind wings of a clear yellow, and having 
a pale orange costa.—Id. 
Is Saturnia Carpini Double-brooded ?—] see Mr. Oldfield 
(Entom. vii. 139) enquires as to the double-broodedness of 
Saturnia Carpini. Like Mr. Oldfield, from eggs deposited in 
April by this species, 1 have now young larve feeding 
on whitethorn, and now just changing their skin for the first 
time. The “verticillate” arrangement of the hairs is well 
seen in these young larve, which at this age closely resemble 
those of the various Eastern and North American species of 
Saturnia, Attacus, &c., in the same stage. As bearing on the 
possible double-broodedness of Carpini, I may state that 
from larve of Saturnia Pernyi, a Chinese species, hatched in 
May and spun up the beginning of August, I have had moths 
emerge both in September and also in the summer of the 
next year.— W. A. Forbes; 35, South Castle Street, Edin-— 
burgh, June 4, 1874. 
[1 have omitted Mr. Forbes’ reference to Humphreys, con- 
fessedly obtained from Haworth, and Haworth confessedly 
from Fabricius, and his probably from some earlier authority. 
ITimagine Mr. Oldfield’s object, and certainly mine, was to 
get out of this copying groove, and to ascertain what was the 
result of recent observation,—the observation of living ento- 
mologists. I admit this would involve a complete revolution 
in Entomology, and | think the sooner it comes the better.—

Aecronycta Alni at Doncaster.—In 1872 I had the pleasure 
to communicate to you the capture of a specimen of
