THE ENTOMOLOGIST. 277 
p. 89 of Mr. Greene’s invaluable ‘ Insect-Hunter’s Compa- 
nion,’ you will find receipts for all the mixtures that have 
been found successful.—H. Newman. | 
Eachanging.— Mr. Newman’s note, appended to Mr, 
Merrin’s communication, on this subject, in the March 
number of the ‘ Entomologist, appears to me to be somewhat 
wide of the mark. That foolish people make such offers as 
Rape for Daplidice, &c., does not prove or falsify the benefits 
an exchange club would confer on the more straightforward 
class of collectors, especially if established on a somewhat 
broader basis than hitherto. Indeed, I would ask why a 
Botanical exchange club can be satisfactorily continued, and 
not a Lepidopterists’? I would like to lay the following 
points before the readers of the ‘Entomologist, and urge 
some of their London brethren to take the matter seriously in 
hand. First. The old club succeeded ; and it was only in 
compliance with urgent medical directions that | discontinued 
my connection with it, when, of course, the labour became too 
heavy for Mr. Merrin to carry on alone. Secondly. The 
greater part (in fact, nearly all) of the members were perfectly 
satisfied with the exchanges made. Thirdly. Although no 
rare species were sent to us, very many good local ones were 
(such as Ichneumoniformis, Elymi, Blomeri, Rubricata, 
Lapidata, &c.); and a great improvement was made in the 
condition of the insects sent from year to year. Had the 
club been continued, all bad or indifferent specimens would 
have been rigidly returned to the senders or destroyed; but, 
on first starting, this was held to be too discouraging to 
young entomologists. Fourthly. Since the discontinuance of 
the club I have had numerous letters from members expres- 
sive of regret at its discontinuance, and of hopes for its 
re-establishment; and, of the forty-two members of 1870, I 
feel assured thirty (at least) would join a new club; and were 
this established, under the auspices of a few better-known 
entomologists, this number would be greatly augmented from 
the provinces, and many London collectors would also join. 
Thus a club could be started on a solid foundation; and, to 
such a one, the better class of entomologists would gladly 
send their duplicates (after supplying their cmmediate friends), 
in preference to answering advertisements from unknown 
collectors, and amongst which we see such absurd offers as
