resting-place on the side of the glass jar in which it was con- 
fined, and in which the stale stalks of the buckthorn remained, 
rather than take up a position on the other plants. Its food, 
however, arrived in time: Mr. Holland’s supply was received 
on the morning that Gonepteryx Rhamni stood a good chance 
of starving. ‘The buckthorn was placed in the cage; the 
‘larva soon ascended the stalk, and that night rested happily 
in the midst of plenty. It is now a healthy pupa, and will 
probably be liberated shortly in the imago state to seek to 
propagate its species in a country where few are to be found.

Hermaphrodite Argynnis Adippe.—\ have taken a perfect 
specimen of an hermaphrodite Adippe: the two right wings 
male, and two left wings female. Can you tell me if this is 
unusual ?—R, J. Slent ; 70, Queen Street, Portsea.

In Search of Chortobius Davus, and what I obtained.— 
On my visiting the Albert Museum, at Exeter, to see the 
collection of insects of the late Mr. D’Orville, of Alphington, 
the curator in conversation informed me that C. Davus was 
taken many years ago on Yes Tor, near Okehampton, by a 
gentleman who collected butterflies, when on his school 
holidays. Knowing this to be an out-of-the-way place 
for entomologists to get at, I laid up the conversation in my 
breast, and determined to see for myself at the first oppor- 
tunity. Thanks to the railway opening last autumn, that 
opportunity occurred this summer. Yes Tor is said to be the 
highest tor on Dartmoor; by the ordnance map it is 2050 
feet in height. I started from Plymouth, 12th July, by the 
10 o'clock train; and after passing through lovely valleys, 
woods, and moorland scenery,—for which the south of Devon 
is so famed,—I arrived at Okehampton at 11.40; and a 
beautiful bright day it was. I at once started for Yes Tor, 
net in hand, and ready for the first insect that turned up. On 
I trudged until I got on the top of the Tor, about 2.30; not a 
single Davus to be seen. While on the Tor I captured the 
only two insects I saw; after one I had a good run,— 
the wind blowing very fresh at that altitude, while 200 yards 
down it was a dead calm: they both turned out to be 
- L. pectinitaria. On my way up and down I only saw about 
fifty butterflies, nearly the whole of which were C. pamphilus,
