2i 4 DEL A GO A BAY. 



soft covering whilst eating. When they want 

 to add to their houses they will leave their food- 

 plant, should the fibre of its wood not be to 

 their liking, and bite a piece of stick off another. 

 The new piece is first attached at the top, where 

 it stands straight out ; but by some means they 

 work it down by degrees, and also fasten it at 

 the bottom, so I suppose they are able to turn 

 round inside their case for the purpose. For the 

 final change to pupa they make a very strong 

 loop, and completely twist up the soft material. 

 I believe the females of these moths are wing- 

 less, many never leaving their cases. I have 

 kept very many, but none have come to maturity, 

 the pupa? of those I have cut open always being 

 full of nothing but dust. Some of these encased 

 caterpillars place the bits of stick crossways, 

 finishing in a point, whilst others make use of 

 grass or sand as a covering. 



The larvae of many beetles are protected by a 

 covering of their own excrement. I found some 

 of a most vivid scarlet completely hidden from 

 view in this way.
