NOTES AND OBSERVATIONS. 911 
G. Down, several instances were observed of this buttertly being 
attacked and killed by a green bug. In some instances the butterfly 
was still alive, and in others just dead and in perfect condition. 
Four of the bugs were taken and sent by the Rev. G. Crawshay to 
Dr. C. J. Gahan at the Natural History Museum. Dr. Gahan 
identified the bug as Zicrona cerulea, L., and said there was no 
record of this species attacking living butterflies and inquired 
whether the butterflies were dead when attacked. I may say that 
each of us saw butterflies still alive with the bugs adherent to their 
thorax and abdomen. The bugs were only noticed on a small area 
of the Heath, which was a breeding-ground of coridon, where pairs 
of this insect were lying about on the ground or on grass stems. 
Both males and females were attacked. The weather at the time 
was very hot and sunny, and the ground very dry.—W. GIFrrorD

AGRIADES CORYDON IN SHROPSHIRE.—This afternoon I caught a 
perfectly fresh male of A. corydon at the foot of the Longmynd, and 
my friend, Mr. M. J. Harding, saw another. I have collected in 
this neighbourhood, on and off, for thirty years, and never came 
across this species before, there being no chalk or limestone in the 
vicinity, which is my reason for recording the capture. I can find no 
note of its prior occurrence in this county.—F. B. Newnuam, M.A.; 
Church Stretton, August 20th, 1916. 
YPSOLOPHUS MARGINELLUS, F., In Essex.—On the 5th inst. I 
was rather surprised at the sight of an old Surrey friend in the 
shape of a 2 marginellus in the most perfect condition on a close 
fence at Leytonstone. This fence bounds one side of a garden which 
seems to be entirely used as a kitchen garden; I was unable to see 
any juniper therein, but it must grow very near the spot where I 
found the moth, as it was in the finest condition. Another old Surrey 
friend turned up on the following day in the shape of Pyrausta aurata, 
Se. A common enough species, of course, in many places, but I had 
not seen it in this neighbourhood before. If I am not mistaken 
Y. marginellus is an addition to the Essex list of Micro-Lepidoptera.

‘ZYGAENA FILIPENDUL#.—] collected nearly 3000 pupe of this insect 
near Ventnor last month. Of those that emerged 2108 were more or 
less normal in colour and markings, 87 had the outer pair of spots, 
and 430 the middle pair of spots united. In 17 instances only were 
both middle and outer pairs united. Over 300 failed to emerge, mostly 
through being ichneumoned. The two best variations were one male 
and one female, in which the lower of the two basal spots was pro- 
longed as a bar until it joined the centre pair of spots. In the case 
of the male the right wing was normal, but in the female the varia- 
tion was the same on both wings. Probably they are progeny of the 
same parent. I paired them and have about 120 ova, and shall be 
interested to see to what extent the variation is transmitted. I may 
add the ground colour of quite 20 per cent. seemed more decidedly 
blue than green.—Hrnest Corne“tu; Burmah, Newport Road, 
Ventnor, Isle of Wight.
