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. T. Porritt ; Hiidders-

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 (Brassica^ 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 objeciion 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.

[My plan is to wash the under side, that is the side not 

 exposed to light, witli 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 miles with beetles ? I find Mr. Greene's 

 method in his book very difficult, for in taking the inside out 

 I generally spoil the insects. — E. F. Clark ; Vfton Rectory, 

 Sontham, 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. — Edward Newman. ] 



Robert Service. — Name of Moth. — I 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
