underneath, the flame will not pass through, but will allow 
all the heat from it to do so. The larva may then be blown 
over it from the side, and thus altogether avoid the unplea- 
santness of the other method.—Geo. JT’. Porritt; Hudders- 
Jield, April 5, 1876. 
A. M. Brown.—Preserving Moths from Mites and Grease. 
—Can you tell me whether you have found dipping moths 
and butterflies into a solution of corrosive sublimate in 
spirits of wine a good plan for preserving them, instead of 
camphor? I tried the experiment the other day on two 
butterflies (Brassice and Napi), and found that even after 
they had been thoroughly dried at an open window, the 
silky hair on the thorax was matted together, and the subli- 
mate had crusted in small cakes all over the wings, which 
cannot be removed by a camel-hair brush. I should be glad 
if you or any of your correspondents could tell me the cause 
of this, and suggest a remedy, or a more efficient way of pre- 
serving the insects. The objection to camphor is that, since 
it must evaporate, in such a small space as a cabinet-drawer 
the little particles will settle on the wings of the specimens.

stead, Herls, May 9, 1876. 
[My plan is to wash the under side, that is the side not 
exposed to light, with the solution; using a camel’s-hair 
brush, and afterwards making it thoroughly dry.— Edward 
Newman. | 
E. F. Clark.—How to prevent Grease in Moths and 
Mites with Beetles—Can you tell me how to best prevent 
grease in moths and mites with beetles? I find Mr. Greene’s 
method in his book very difficult, for in taking the inside out 
I generally spoil the insects.—£. F. Clark ; Ufton Rectory, 
Southam, Warwickshire, May 1, 1876. 
[I know of no better instructions than those in Mr. Greene’s 
‘Insect-Hunter’s Companion;’ they appear to me to be 
excellent.—ELdward Newman.|} 
Robert Service.—Name of Moth.—I1 shall feel greatly 
obliged if you can tell me the name of the small moths, a 
male and female, which I send you by this post. I regret to 
trouble you, but just now I have no books in which the 
Micro-Lepidoptera are described. These moths were very 
abundant in an oak plantation at Malice, near Dumfries, on
