on poplar and the rest on willow, but the poplar-fed ones got on very much 
the best, and the pup are much larger—W. E. Burter ; Hayling House, 
Oxford Road, Reading, March 18, 1892. 
Norres on LepipopTERA TAKEN 1N 1891.—Please allow me to correct 
a slight mistake in the above (Entom. 82). The Hupecilia geyeriana bred 
by Mr. N. M. Richardson was from Pedicularia palustris gathered by himself 
on the same spot where, a few days after, I gathered that from which it was 
bred by Mr. Eustace Bankes.—O. P. CAMBRIDGE; April 12, 1892. 
Coccip& From JamAica.—The Institute of Jamaica are issuing sets of 
Coccide prepared by Mr. T. D. A. Cockerell, Curator of the Museum. ‘The 
following ten species are comprised in Set 1 :—'l’he Rufous Scale (Aspidiotus 
articulatus); the Masked Scale (A. personatus): the Cocoanut Scale (Chio- 
naspis vandalicus); the Pepper Scale (Diaspis n.sp., Ckll.); the Croton 
Chaff-Scale (Parlatoria pergandii); the Filiform Palm-Scale (Ischnaspis 
Jiliformis); the Light-spotted Scale (Aspidiotus ficus); the Purple Scale 
(Mytilaspis citricola); the Brown Scale (Leucanium hemisphericum); the 
Black Seale (Bernardia ole). 
EntomonocicaL Pins.—In my article on pins, in the March number 
of the ‘ Kntomologist,’ I mentioned, when recommending the use of silver 
pins, that it would be necessary to have a guarantee that the wire is of pure 
silver. As regards this point, I have received a further communication trom 
Messrs. Watkins and Doncaster, to the effect that the wire used is not pure 
silver, but consists of 92 per cent. of pure silver and 8 per cent. of copper 
and alloy. Messrs. Watkins and Doncaster obtained their wire from the 
successors to the makers that supplied me with the material for fifteen years 
or more (they were originally recommended to me by Prof. Flower of the 
British Museum), and it is, I believe, the same quality as I have been 
accustomed to use. As I know that this wire is perfectly free from the 
attacks of verdigris in Coleoptera, I have little doubt that it will prove also 
satisfactory for Lepidoptera and insects of other orders in which I have 
tested it but little. I think, therefore, that instead of insisting on the wire 
being of “pure silver,” it be merely required to be up to the standard of 
92 per ceut. of pure silver, the purposes entomologists have in view will be 
secured. As regards the price of the pins made from this silver-wire, I see 
that Messrs. Watkins and Doncaster quote them in their new price-list at 
from 7s. 6d. to 8s. 6d. per 1000. I believe, from my own experience, that 
this is a very reasonable price; and Iam glad to mention this as Messrs. 
Watkins and Doncaster have been put to a good deal of trouble in the 
matter, and I feel that the thanks of entomologists are due to them for 
introducing into commerce an article that will be of considerable value to 
working entomologists, but for which the sale can never be very extensive.

Revaxine Lepmovrera.—Mr. Anderson (Entom. 95) asks for in- 
formation as to the best means of relaxing foreign Lepidoptera. The 
method I have employed for a number of years has always afforded me 
most satisfactory results, and I have, therefore, great pleasure in giving a 
few particulars concerning it. First, a zinc-box is obtained. A very con- 
venient size is one measuring 12 in. by 103 in., by 94 in. deep ; three trays, of 
equal depths, made to lift out easily, with perforated bottoms, and a block in 
each corner to prevent the upper falling into the lower ones; the lid should 
be on hinges. Into the trays are placed pieces of ordinary house-flannel,
