migrated, either naturally or through the instrumentality of 
man, from the old to the new continent, or vice versd. It is 
stated, and I doubt not on good authority, that there are two 
broods of this mischievous insect in America. At present we 
know of but one in Britain. Let us hope that a second may 
not hereafter reveal itself.

Obtaining Eggs from Captive Lepidoptera.—In the 
‘Canadian Entomologist’ for September Mr. T. L. Mead, of 
New York, gives a description of a simple and easily- 
constructed cage for keeping the females of Lepidoptera in 
health and vigour until the eggs are deposited on the food- 
plant. As the method in some of its details is new to me, I 
thought it might also prove so to some of your numerous 
readers, and therefore copy that portion of his note verbatim. 
Mr. Mead says:—“ A notch is cut in the side of an empty 
wooden-box, through which a branch of willow or other 
appropriate food-plant is passed, care being taken to select a 
leafy spray, so as to partially fill the box with foliage. It is 
then covered with gauze, tacked fast on one side and part 
way on the adjoining sides, that on the fourth side being held 
down by a piece of wood fastened to the remaining flap of 
gauze. ‘This renders easy the examination of the contents at 
any time. Now, a saucer of dried apples, sugared and partly 
filled with water, is put in, and the cage is complete. 
Butterflies, like Limenitis Arthemis, will live in such a vivarium 
for two weeks and more after their capture, and appear to | 
enjoy the food provided immensely, laying many more eggs 
than if enclosed in a bag and allowed to perish of hunger and 
thirst. Ihave often captured specimens and dropped them in 
upon the pile of dried apples: instead of fluttering about and 
endeavouring to escape they instantly unrolled their tongues, 
and feasted for several minutes upon the repast prepared for 
them without a motion of the wings.’—Henry Leeks;
