NOTES AND OBSERVATIONS. 935 
flies were attacked. Professor Poulton exhibited before the Entomo- 
logical Society last year a pair of the same species of bug, which I 
found feeding on a male Agriades corydon at Royston. It was then 
suggested that a spider had killed the butterfly before the bugs 
discovered it (‘Proc. Ent. Soc.,’ 1915, p. exix).—E. A. CocKAYNE ;

[When sending Mr. Crawshay the name of the Pentatomid bug, 
I had forgotten the particulars of Professor Poulton’s exhibition, 
but very soon after recalled it; and on the following day sent a 
complete extract from the Proc. Ent. Soc. to Mr. Crawshay. This 
unfortunately does not seem to have reached Dr. Nash in time to 
be incorporated with his note.—C. J. G.] 
DicRANURA vinuLA Two YEARS IN Pupat Strace.—In August, 
1914, I cut from the bark of a poplar tree in Ayrshire a cocoon of 
Dicranura vinula. At the same time I was feeding up a number of 
vinula larve which I got from London. I mention this to indicate 
that the cocoon was in existence at the same time as half-grown 
larvee (all of which died before feeding up). I have the cocoon now 
and the pupa is still living inside. That means two years at least in 
that state, however long it was thus when I got it. I have had it in 
artificial heat nearly the whole of the time, and last year brought 
out in the same temperature three vinula obtained from London in 
the pupal state as an experiment. I have now removed the cocoon 
to an ordinary temperature, at which I purpose keeping it till it 
either emerges or dies. There is a slight opening at the bottom of 
the cocoon, caused by the shrinkage of the bark, and the pupa can 
be distinctly seen to move when touched.— Ww. A. R. Jex Lona. 
Latr APPEARANCE OF DryAs PAPHIA.—On September 9th I 
saw a number of D. paphia, probably ten or twelve, in an open space 
in one of our woods. They were feeding on the blossoms of devil’s- 
bit scabious (Scabtosa succisa) in company with a number of Pyramezs 
atalanta, Vanessa 10, A. urtice, Polyommatus icarus, Chrysophanus 
phieas, a couple of Gonepteryx rhamni, also numerous Plusia 
gamma, and the usual assortment of insects that collect in such 
places when it happens to be a sun-trap on the rare occasions when 
the sun shines in this gloomy September. Surely this is an un- 
usually late date? I rarely see one here after the middle of August. 
These butterflies did not look very weather-worn ; indeed, only one 
female looked quite worn out. I noticed they only visited the 
scabious blooms, neglecting betony, bramble, and heather.—E. G. B.

CHRYSOPHANUS PHLAIAS, AB. ALBA, IN CorNWALL.—On August 
22nd last I had the good fortune to net a specimen of the form 
of C. phi@as known as ab. schmidtiz. It was settled on a stone 
at the side of a rough combe at Pentire, near Padstow, in Cornwall. 
The ground colour was silvery white and very conspicuous. Un- 
fortunately it was not in very good condition, the hind wings being 
a little torn and frayed.—Grorrrey Harper; Byflete, Battledown 
Approach, Cheltenham. [As the specimen of C. phleas recorded
