This size will do for ordinary use, but for very large or very small 

 moths other sizes are required. 



Fig. 21. 

 The second is merely a block of wood three inches square, and one 



inch thick, with an upper 

 groove half an inch wide for 

 the body of the insect, and a 

 lower one about the same 

 width to receive a strip of 

 sheet cork ; before putting in 

 Fi 22 the cork, however, several 



holes should be made along the centre of the groove, just large enough 

 for the size of the pin used. Both boards slope slightly toward the 

 centre. In the long board, the wings of the butterflies are held in 

 position until dry by thin pieces of glass, or by cards secured by in- 

 sect pins." — Editor. 



Dr. J. G. Morris (in Canadian Entomologist) gives anew use for the 

 forceps in Forficula. Speaking of observing these insects in numbers 

 on his study table, last summer, he says; "Each one of them, before 

 he took flight, for they were active, would bend his body back and 

 lift up the short elytra with his forceps before the wings would expand, 

 and this they did invariably."
