86 THE ENTOMOLOGIST. 
found that some of them, after having left the males, fell on 
to the ground in out-of-the-way places, whence they could 
not possibly return to the original nest!” We unfortunately 
did not note the sex of those individuals that we intercepted 
in their return (?) trip; but we cannot help expressing our 
belief that, at least, in this case, there was scarcely an 
appreciable amount of “returning” on the part of those 
whose exodus we have just described, although so many 
were caught by the nearer trees and shrubbery. Is it 
probable that these insects could find their way to a small 
under-ground nest, where there was no “travel” in the 
vicinity, other than the steady departure of individuals, who, 
like themselves, were terribly bothered with the wings they 
were carrying about with them?—C. C. Abbott; from the

Hints on Breeding Teniocampa opima, &c.—As very 
many have failed to breed this species from the egg, possibly 
a short account of the method I have found very successful 
may be interesting to some: from a batch of eggs, kindly sent 
by Mr. Owen, of Liverpool, April, 1873, about a hundred 
larve hatched on May 15th. They were placed in a three- 
ounce wide-mouth bottle, with sprigs of broad-leaved willow: 
tie over the mouth of the bottle with fine muslin, and then 
place it mouth downwards ona shelf; this keeps the food 
fresh, and allows a little air to enter. J found that a bottle 
loosely filled with suitable sprigs kept perfectly fresh for a 
week ; now, as the young larve spin a quantity of silken 
galleries, in which they rest and change their skins, it is 
rather difficult to change their food without disturbing them, 
and to avoid this, having filled a second bottle of the same 
size and character with food, untie and remove the muslin 
from the neck of the first bottle, and place the two bottles 
neck to neck. Securing them in this position, by binding a 
strip of muslin two inches wide tightly round the rims of 
them, the larve can now crawl from the stale to the fresh 
food, without injuring or disturbing those that may be 
changing their skins. After two or three days remove the 
first bottle, and clean it out carefully, for repeating the 
process when required. After the second change of skin it 
was necessary to divide my family into two separate bottles, 
and work as before. After the third change, procure a large
