LEPIDOPTEROUS INSECTS 257 



box is full and the lid can be put on without too much 

 pressure. Before placing the lid, a piece of paper is puc 

 on top of the cot ton- wool so that the lid will not dis 

 place the last layer. The date and locality may be writ- 

 ten on this paper. The parcel should be wrapped up well 

 in strong paper, the address and stamps placed on a tag. 

 Naturally the insects must be quite fresh whien thus 

 packed, otherwise the legs and antenn:Te will break from 

 nearly all and ruin them. When in the receipt of such 

 a box of specimens it is a good plan to remove only the 

 lid and place the whole for about 12 hours in the relax- 

 ing box^ without attempting to see w^hat the contents 

 are. Afterwards the specimens may be removed Avith 

 little risk. If, however, they are kept under moist con- 

 ditions for a longer period, the gum dissolves and the 

 insects stick to the wadding. When removed, the speci 

 mens should be placed on paper in the relaxing box until 

 they are ready to pin and set.
