THE WEEKLY ENTOMOLOGIST.

we are bound in justice to tbe Rev. 
Mr. Andrews to state, through our 
own error in copying 1 . The notice 
was intended for No. 16. If it had 
been inserted there “ last week ” 
would have been quite correct. But 
we had to postpone it through press 
of matter ; and thus “ last week,” in- 
serted in No. 17, appeared to be a 
mistake. We regret that the error 
should have occurred. 
For “ J. C. Dale,” read, “ T. 
Parry, Hank, Merthyr Tydvil ,” at 
the foot of the notice headed “ Crabro 
Lindensis.” Page 141, No. 1 8? 
Vol. 2. 
We have many valuable com- 
munications awaiting insertion. 
These are not postponed through 
any preference for the records al- 
ready printed, but simply because it 
is impossible to insert all in one 
number. Thanks to the senders. 
Mr. Francis Owen, of Leatherheacl, 
Surrey, requests us to inform our 
readers that he has ova of S. Ocella- 
tus, which he will be happy to send 
to entomologists in want of them, on 
receqxt of postage. 
Will our correspondents be kind 
enough, in writing- observations for 
our pages, to range as widely as 
possible over a subject. Let us have 
the history, when it is possible, of 
the egg, larva, and pupa, as well as 
imago. All detailed information res- 
pecting habits is of the greatest im- 
portance. 
OBSERVATIONS. 
Diptera. 
Syrphidce. — Woods, in summer, 
teem with the merry hoverer flies. 
We see them at every turn hovering 
motionless in the air, and, whether 
on the wing or at rest, keeping up all 
the while a shrill continuous hum- 
ming. They tell us ever of wooded 
glades and long afternoons of sun- 
shine. Bright creatures are they — • 
the metallic lustre of their forms 
being often varied by spots and 
bands of pale and golden yellow. 
We are told by those who have made 
them their study, that they have 
their strong partialities like other 
created beings, and evince strong- 
preferences for certain flowers ; in- 
deed, they tell us that each flower 
has its own peculiar admirer from 
among this vastly numerous tribe, 
and that the beauty of its corolla is 
heightened by the exquisite form 
that seeks its sustenance among its 
juices. Be this as it may, few but 
those who have studied their life 
history can possibly be aware of 
their early stages of being, or the 
many lives that have been sacx-ificed 
before they assume their winged 
state of existence. The eggs of not 
a few are laid by the parent insect in 
the leaves of such plants as are in- 
fested with Aphides, here in the 
summer and autumn ; and the grubs 
prove most formidable enemies to 
the unfortunate plant lice. Their
