136 THE ENTOMOLOGIST’S RECORD. 
the anterior and middle pairs of legs and hold the posterior pair more 
or less along the body, but this is very little elevated so that their head 
does not touch the surface on which they rest. I think B. illuminatella 
rests in the same way. A moth in the habit of standing on its head 
can easily do so on a flat leaf with space around, but this position may 
not be convenient when resting among fir or pine needles.—ALFRED

LiwvENITIS SIBILLA IN SurRREY.— Sitting in the garden here 
(Godalming) feeding young pheasants on ants’ larve, my attention 
was drawn to a couple of beautifully fresh Limenitis sibilla love- 
making on the syringa blossom. This was on Monday, July 8th. 
This butterfly was dear to my childhood when I counted it a rarity 
and considered the New Forest its headquarters. I see that South 
does not give Surrey as one of the localities where it occurs, and shall 
be interested to learn if there are other records for this county.— 
P. A. H. Muscuamp, Charterhouse, Godalming, Surrey. July 10th. 
ToRTRIX VIRIDANA aT Ranmore.—Being at Ranmore on June 12th 
I could not help noticing that many oak trees were much defoliated. 
At one spot some dozen trees were in view that had very little foliage 
left, and that presented a very brown tint. Of these trees one at- 
tracted especial attention. All the cracks in the bark of the trunk 
were full of the cocoons of Tortrix viridana. So numerous were they 
that on a selected strip of bark on one side, six inches (6’’) wide and 
thirty inches (80) high, 163 (one hundred and sixty-three) cocoons 
were counted, and they were equally numerous elsewhere on a trunk 
four or six feet in circumference, and extending upwards as far as 
could be readily seen. Seated on the trunk up to about nine or ten 
feet, 64 (sixty-four) imagines of 7. viridana were counted, several still 
expanding their wings. These sixty-four were obviously those that 
had emerged that morning up to the time of observation (11 a.m. 
Greenwich time). The moths, so far as could be seen, were equally 
abundant above, but could not readily be counted. The remarkable 
circumstance was that, though there were at this spot a good many 
trees, and at Ranmore generally, a great nnmber of trees denuded of 
leaves in apparently the same way and to an equal extent as this 
particular one, on no other tree were there any cocoons on the bark, 
beyond a few odd ones. 
Knowing that 7’. viridana pupates amongst the leaves of the tree, 
and often on low plants, to which the larva falls from the tree, a tree 
was selected because it had some branches within reach, a tree that 
looked as if punished by larve to as full an extent as any other. On 
this tree cocoons and pup were very abundant in the leaves, or what 
remained of them. The leaves, in fact, had all disappeared, except 
of most leaves just so much as was necessary to contain the cocoon of 
T. viridana. 
Selecting a twig on an accessible branch of this tree, a -twig 16 
inches long with three shorter twigs arising from it, the cocoons and 
pup on it were counted and found to number 34 (thirty-four). Itis 
difficult from this to calculate how many were on the whole tree. 
The twig examined was probably less than a thousandth part of the 
tree, but if so, this would give the tree 30,000 7. viridana chrysalids.
