IMPERIAL MISFORTUNES. 
One of the most important discoveries 
last year was that of the larva of Gra- 
cilaria Imperialella ; as soon as it was 
known that this species had been bred, 
and from what, a profound sensation 
was experienced in the Micro-Lepi- 
dopterological bosom from one end of 
Europe to the other. Every one was 
intent on finding the larva of so great a 
rarity, and of course we expected to be 
inundated with the coral-red larvae, just 
as in May every post brought a supply 
of Micropteryx larvae. Nor were we 
altogether disappointed, for in due time 
a letter was received from one who had 
taken the insect. 
“July 17, 1861. 
“ I send you by this post what I hope 
is the larva of G, Imperialella. I found 
the leaves to-day, in the very place where 
I took the imago last year. I looked 
carefully for more than an hour, and 
only found what I send, which I fell in 
with soon after I began to search, all in 
the same place, and close to the locality 
of the imago, as above-named. It must 
be very local, as well as very scarce, if 
this is Imperialella,” 
Unfortunately the box of larvee so 
temptingly described never came to band, 
having gone astray, we suppose in the 
post office. So there was Imperial Mis- 
fortune No. 1. 
A week later a letter was received 
from Professor Frey, in which the fol- 
lowing passages occur : — 
“I made an excursion on the 18th of 
July, in order to collect and observe the 
larva of Gracilaria Imperialella. I had 
noticed the mine on Orobus in 1857, but 
as it does not occur near Zurich, and is 
extremely local, as it appears, having 
but little leisure time, I was not suc- 
cessful in again meeting with it. As 
Gracilaria Imperialella has occurred 
several times in England I send you 
some notices concerning it for the ‘ In- 
telligencer.’ The time for "seeking the 
larva is the beginning of July, not the 
second half of the month. [Very con- 
solatory to read this on the 25th of July ! 
Imperial Misfortune No. 2.] On the 
18th of July I found a multitude of 
empty mines, and only after a prolonged 
search a few which were still inhabited 
by law®. In some there was still a 
young larva, yellowish green, with a 
brown head. In the remainder the larva 
had already assumed its coral -red tint 
preparatory to changing to pupa. The 
mine is on the under side of the leaf, 
and the larva loosens, in the first place, 
ahnost the whole of the lower cuticle of 
the Orobus leaf. It begins to eat the 
parenchyma of the leaf first at the edges 
of the mine, so that the green mine.
