THE ENTOMOLOGIST. 21 
sisters and I have, at different times, found Xanthia gilvago 
and Cirrhedia xerampelina within the limits of our own 
garden.—[ Miss] Anne Steele Perkins; Ashgrove, Overton, 
Flintshire, December 2, 1873. 
Xanthia Aurago (Entom. vi. 564).—Permit me to say that 
I think Mr. Gregson’s note scarcely adds to our knowledge of 
the westerly range of Xanthia Aurago. The insect having 
long ago been recorded to occur in Ireland, its capture at 
Llangollen is not ‘remarkable, so far as westerly longitude is 
concerned.— Edwin Birchall. 
Hybridizing Smerinthi.—This year I bred out specimens 
of Smerinthus ocellatus and S. Populi, which I was lucky 
enough to have crossed, male Populi with female Ocellatus ; in 
about twenty-four hours after she began to deposit her batch 
of eggs: they were deposited in batches differing in 
number; they were all unattached; the number deposited 
was a hundred and seventy, deposited at intervals, and 
more so after being disturbed. The duration in the egg 
state was fifteen days; colour at first was bluish, then 
changed in a few days to a light flesh-colour; the caterpillar 
fed on apple-leaves. After feeding for three weeks began to 
wander from their food, and died with the diarrhea. If you 
can throw out a few hints it may be a guide for the future, to 
myself as well as others, how to treat them if lucky enough 
to cross. Is this a common occurrence ?—John Williams ; 
100, Well Street, Hanley, Staffordshire, November 12, 1873. 
Description of the Larva of Macrogaster Arundinis.—The 
following notes on this larva may be useful, as being fuller 
than those given in your work on ‘ British Moths.’ On May 
9th, 1873, I found a single larva of this species inside the 
stem of a reed, at Wicken Fen. The following description 
was taken on May 10th:—Bulk slender in proportion to 
length; head flattened, about half the size of the 2nd seg- 
ment, and retractile within it; form cylindrical, but tapering 
towards the extremity; a corneous plate, with ten black 
spots on the 2nd segment. The larva is covered with a 
number of warts, emitting some six short hairs on each 
segment, but more numerous on the last. Spiracles pink, and 
not easily perceptible. General colour a pale rose. Head 
dull ochreous; mouth black, with two black spots on each 
side. Medio-dorsal line conspicuous, being of a darker tint
