hide its diminished head before the 
joint offspring of a Skipper and a 
Burnet (P." Lima and A. Filipendula ) 
or an Eyed Hawk and a Swallow 
prominent, yet I have seen these ill- 
matched pairs in copula, — the former 
at large, — the latter in my breeding 
cage. I say again, if any one doubts 
it let him ask my friend Mr. Lynch, 
who also saw both cases. Unfortuna- 
tely the female Burnet would not lay, 
and the ova of the female Dictaa were 
infertile. I have heard o/(and believe 
though I cannot vouch for it) the 
copulation of S, Populi with P. 
Bucephala. Id. 
Mania Maura. Two larva off 
sallows in the spring. Hot knowing 
what they were, for the descriptions 
of different authors failed to point 
with any certainty to Maura, although 
I had my suspicions that they were 
that species, I took the following 
detailed description. — 
Colour greenish grey ; two light 
grey stripes on either side of the back, 
from the middle of the 5th. to the 
13th, segments. On the back of the 
3rd. 4th. and 5th. segments is a 
small white spot. From the 5th. to 
the 13th. segments inclusive, and 
also on the second segment is a dis- 
tinct red spot. This spot is on the 
side of the larva. A. slender white 
stripe joins all these spots down the 
side. The belly is light grey and that 
part of the body which is below this 
longitudinal stripe is much lighter 
than that above it. A distinct black 
band divides segments 11, and 12. 
From each red spot, except that on 
the 2nd. segment, proceeds a white 
line running from the spot upwards 
towards segment 13. This line be- 
comes more and more distinct the 
nearer it gets to the 13th. segment. 
The head is very hard, grey, irrorated 
with darker. The larva remains 
hidden during the day, among small 
lumps of turf. When taken out to be 
described, however, it walked about 
very actively, and never rolled up. 
The cocoon was a very large one, 
among the loose soil on the bottom. 
On the 24th. of April, I find a note 
that a brood of Aurantiaria emerged 
from the egg. These I fed on birch 
in their early stages, the oak being in 
a very backward cpndition. Again, 
on May 9th. I have it recorded that 
the brood had decreased in number. 
Their favourite food seems to be lime. 
This they eat most voraciously. On 
the 19th. of May, I find the following, 
the larva of Aurantiaria are now al- 
most full fed, while those in the 
neighbourhood of Bowdon seem only 
to have been out of the egg about 10 
days. This larva is variable to a most 
singular extent. Those unacquainted 
with them would never suppose them 
to be the same species. In some the 
yellow marks on the back and sides 
assume the appearance of regular 
stripes ; in others they are only 
visible as small successive spots. The 
larva are not easy to rear; they are 
liable to die suddenly, and without 
apparent cause. 
The larva of L. Petraria are, I 
fancy, still altogether unknown. 
There is one spot near Bowdon where
