There is a very striking resemblance between the Compton 
tortoise and its congeners the Tortoiseshells of England, 
both in colours and distribution of the tints^ and the simila- 
rity is equally striking in both the upper and under surfaces^ 
though these differ so much from each other. The Camber- 
. well beauty, a rarity in England^, is here extremely common, 
chiefly in autumn, and is one of the latest seen of all our 
butterflies. The first you named is a pretty fly ; the under 
surface of the wings is very beautifully and richly variegat- 
ed. The genus Grapta is not, I believe, generally adopted ; 
but it seems as natural a genus as almost any other of 
the Nymphalidce, I have found four species in this place, 
and one in the south, all of which can scarcely be distin- 
guished from each other on the upper side, but vary greatly 
beneath. They are all marked by a silver crescent in the 
centre of the hinder wings, on the under surface : the Comp- 
ton tortoise resembles them in this particular, but this is a 
true Vanessa. 
C. — I have two new moths added to my collection, both 
of them of small size. One is a very pretty Tinea, taken 
about ten days ago ; the other I caught last evening, a small 
but handsome Geometra^ The cocoons of the Muff Moth 
( Lophocampa Tesselaris ) and Panther Moth ( Spilosoma 
Acriajy may both be found under stones or boards, lying 
on the ground. A pretty little bug, about as broad as it is 
long, of a polished black, with a white margin ( Cydnus 
? )y crawls about. Ichneumons and Muscce are nu- 
merous. 
i^. — I have noticed, buzzing about the dead leaves which 
lie under the maples, a large Musca that I have not seen 
before ; the abdomen changeable blackish-grey, the head light 
brown, with dark brown eyes, and rather long antennae. It 
is numerous.
