18 NOTES AND NEWS. 
It is very interesting to rear many of those diptera which blotch 
or mine the leaves of plants or trees, or form small galls in flower 
heads. My old friend, Mr. Peter Inchbold, was very fond of this 
pursuit, and very successful in his efforts. The leaves or flower heads 
should be placed in a wide-mouthed bottle or a box, which is 
covered with muslin or a glass top, and has a little moistened earth 
at the bottom. This must be watched from time to time, and a little 
water be added occasionally, for the imagines emerge better from 
the pupz when their surroundings are moist. Some species will 
come out in the course of a few weeks in the summer, while others 
will remain in the larva or pupa state for a long while, or all through 
the winter. 
The parasitic flies (Zachinitde) form a very interesting group to 
which I have paid considerable attention.t I wish Lepidopterists 
would carefully preserve all that they freed from the larve of moths 
or butterflies, and note the species from which they emerge, and if 
they would send them to me I should be much obliged, and would 
gladly name them for any one who would like to keep a collection 
of them himself. 
In conclusion, I may add that I shall have great pleasure in giving 
any information that I can upon any points respecting the study of 
diptera, and shall be very pleased if I can induce a few more 
entomologists to take an interest in this order of insects, which is 
much more neglected in Britain than on the Continent.
