NOTES ON COLLECTING. 247 
while to place the foregoing on record; also to add that the lively 
Triphaena janthina occurred about the ivy on the ash-trunks.—Inmn. 
Noroponta cHAoNTA AND N. popon#A NEAR Croypon.—l haye bred 
one Notodonta chaonia and three N. dodonaca from larvee taken last year 
at Farley, near Croydon. I also took the imago of the latter species 
at rest on a tree-trunk this year. Is not this a new locality for NV. 
chaonia? perhaps also for the more common of the two species, NV. 
dodonaea ?—C. B. Antram, Croydon. August 13th, 1900. 
Forctnc CattimorpHa HERA.—Following up my notes on the 
‘ Forcing of Callimorpha hera”’ (ante., p. 130), April 7th, saw the last 
of the larvee change into the pupal stage, the first imago appearing on 
May 8rd. For about three weeks the perfect insects continued to 
emerge in twos and threes per diem; quite 50 per cent., however, of 
the pup failed to produce imagines, owing I am afraid to my having 
kept them too dry, and there was also a fair number of cripples ; 20 
per cent. were of the yellow aberration, and out of forty specimens only 
two were of the intermediate form.—Ismp. 
FINDING LARV® OF CH@ROCAMPA PORCELLUS BY LAMPLIGHT.—On 
July 31st, my friend Mr. E. Field and myself started at dusk to go to 
the village of Cherryhinton to look for the larve of Choerocampa 
porcellus by lamplight. After a brisk walk we reached our destination, 
and haying lit our lamps we set to work upon the piles of Galium 
rerum. Some little time had been spent in a fruitless search, when 
my friend found a larva of at least three inches in length, and after 
that we kept on finding them at varying intervals, the majority 
having brown skins, but a few with ereen ones. At eleyen o’clock we 
struck work, and on counting our captives we found the united take 
of lary to be forty C’. porcellus, three Macroylossa stellatarun and two 
Anticlea sinuata,—i. Crisp, 31 Union Road, Cambridge. 
SMERINTHUS OCELLATUS AND CERURA VINULA TWO YEARS IN THE PUPAL 
staGE.—Referring to Mr. Lane’s note (ante., p. 217) on Smerinthus ocel- 
latus being two years in the pupal stage, I can instance a similar case. 
On June lith, 1898, I took eight eggs of S. ocellatus at Hythe, Kent, 
which produced imagines in June 1899, except one, which remained 
over the second winter in pupa and emerged on May 29th last, in fine 
condition, <A similar thing happened also with a specimen of Cerura 
rmula which emerged early this spring from a pupa bred from an eg 
found with others (which ‘produced their imagines in due course in 
1899), on the banks of the Thames at Barnes, on July 6th, 1898.—

DerILEPHILA LIVORNICA IN THE ISLE or Man.—On the eyening of the 
11th inst. a specimen of D. livornica was seen by Mr. William Garrett, 
of Douglas, hovering over flowers of Silene maritima in the same 
locality where seyeral were seen and captured last year, as recorded 
in the Hnt. Record, vol. x1., p. 166.—H. Suortripce Crarke, F.1K.S., 
Sulby Parsonage, Lezayre, Isle of Man. July 16th, 1900. 
PLUuSIA IOTA ON THE WING DURING THE DAy.—I noticed a number of 
Plusia iota flymg about in the garden to-day about 12 o’clock noon, 
some of which 1 caught whilst hovering over flowers of blue lobelia 
which are now in bloom. Is this usual? The sun was shining 
brightly at the time. I haye frequently seen specimens of Plusta gamma 
flying over flowers in the sunshine, but neyer P. iota.—Inip,
