TO CORRESPONDENTS. 
T. A. — Your letter is very amusing, 
and had we space we would insert it; 
but not a hundredth of our readers 
trouble themselves at all about the con- 
troversy, and the “ knowing ones ” see 
all the clever shifts that you have taken 
the trouble to expose. Let the subject 
drop. 
T. L. — Is. more, please. 
R. E. B. — We are not aware of Dip- 
sacea being double-brooded ; it may keep 
out a long time. 
OBSERVATIONS. 
Habits of Asilus Crabroniformis . — 
While staying with my brother at Chel- 
tenham during the winter, he mentioned 
that he had noticed last August, in 
Devon, a curious fly that appeared to 
be busily engaged with a burying-beetle, 
either using it as a nidus for its eggs or 
as food for itself. Another fly was equally 
busy with a grasshopper it had secured. 
This he captured, and on examination it 
proved to be Asilus Crabroniformis, and 
a large handsome fellow of a tawny 
yellow, with the three first segments of 
the abdomen black, and the wings on 
the inner edge bordered with blackish 
patches. Macquart, in bis ‘ Insectes 
Dipteres,’ says of the Asilidae, “These 
Diptera frequent woods and dry places, 
and we see them on the wing in the 
hottest sunshine. They live generally 
on prey, seizing other insects as they fly 
with their fore feet, and the horny cases 
of the Coleoptera are not even suffi- 
cient armour against the efforts of their 
trunks.” — Peter Inchbald, Storthes 
Hall, Huddersfield ; February 11. 
Xanthia oeellaris . — Through the kind- 
ness of Mr. Doubleday, I am able to 
give more conclusive information on this 
insect than I was (Zool. 6504), and, as it 
may interest the readers of the ‘ Zoologist,’ 
I subjoin his remarks. He states that 
he has received authentic specimens of 
X. yilvago and oeellaris from M. Bellier 
de la Chavignerie, and that all the 
British specimens belong to the former 
speefes. He also adds that Xanthia 
oeellaris is very distinct. The upper 
wings more pointed, slightly falcated, 
and the nervures paler than the ground- 
colour of the wings. I have availed my- 
self of Mr. Doubleday’s kind information, 
and forward the above as a supplement, 
if I may be allowed to call it such, to my 
previous notes.— Robert Anderson, in 
the ‘ Zoologist' for February, 1860. 
NATURAL HISTORY OF THE 
T INKINA. 
Depressaria Depressella. 
The egg is no doubt laid in the spring 
by the hybernated female, or perhaps not 
till the season is well advanced, as the
