size and tapering off again ; the general colour is pale green, 

 with a pale yellow line above the spiracles, which are black ; 

 in each segment there is the appearance of a black ring under 

 the skin, so that if it changed skin again it would be black- 

 ringed. I found it domiciled between two leaves of nettle. —

I think it is Pyrameis Atalanta. 



Mould on Insects. — Can you kindly tell me what to do in 

 the following fix? viz.: — I have a case of moths, many of 

 which have become covered with a white mould, more parti- 

 cularly the antennae and edges of the wings ; I can remove 

 this by brushing, or benzine will take it away for a short 

 time, but it returns again, bad or worse than ever. Can you 

 give me any idea of the cause, and if there is any remedy ? 

 The case is kept in a room where there is a fire daily, so that 

 I do not think it proceeds from damp : many of the insects 

 are valuable, and I am quite at a loss what to do. — W. H. 

 Pearson ; Ivy Hall, Solihull, July 25, 1871. 



The insect in the condition described should be touched 

 with a camel's-hair pencil dipped in a weak solution of cor- 

 rosive sublimate in alcohol; after one or two applications the 

 mould will certainly disappear, and is not likely to return. 



Rearing Zeuzera from the Egg. — The other day I found 

 a number of the leopard moth's eggs, which I wish to rear. I 

 looked in your moth book, and found that the leopard cater- 

 pillars fed on solid wood. I should feel much obliged to you 

 if you would tell me the most practicable method by which I 

 could rear the caterpillars, for I have not got in my collection 

 a single good specimen of the leopard moth. — Cecil Brooks ; 

 6, Kent Terrace, RegenVs Park, July 29, 1871. 



I believe the attempt to rear Zeuzera JEsculi from the a^^ 

 is almost sure to fail. The only mode I can suggest is to 

 confine the moth, by means of a loose muslin covering, to the 

 stem or branch of an apple-tree, and thus compel her to deposit 

 her eggs on the bark : these will hatch in process of time, 

 gnaw little holes in the bark, and feed for a year, at least, on 

 the solid wood, as I have so fully described (Entom. ii. 92), 

 remaining entirely out of sight until the final change to a 

 moth takes place. It will be difficult, if not impossible, to 

 exercise that care over the larvae of Zeuzera which we do 

 over the leaf-eating larvae.
