line drawn through the nead to the extremity of the abdomen. The hind wing 

 should then be moved forward, its anterior margin lying under the opposing margin 

 of the front wing. When the wings have thus been adjusted into the position which 

 they are to occupy, slips of tracing-muslin or of paper should be drawn over them 

 and securely pinned, the setting needles being removed. 



In pinning down the strips which are to hold the wings in place, be careful 

 to pin around the wing, but never if possible through it. When the wings have 

 been adjusted in the position in which they are to remain, the antennae should be 

 attended to and drawn forward on the same plane as the wings, and secured in place. 

 This may ordinarily be done by setting pins in such a position as to hold them where 

 they are to stay. Then the body, if it has a tendency to sag down at the end of 

 the abdomen, should be raised. This may also be accomplished by means of pins 

 thrust beneath on either side. Plate E, Fig. e, shows clearly what is intended. When 

 the insect has been set, the board should be put aside in a place where it will not be 

 molested or attacked by pests, and the specimens upon it allowed to dry. A box 

 with shelves in it is often used for this purpose. This box should have a door at 

 the front covered with wire gauze, and the back should also be open, covered with 

 gauze, so as to allow a free circulation of air. A few balls of naphthaline placed in 

 it will tend to keep away mites and other pests. The time which the specimen 

 should remain on the board varies with its size and the condition of the atmosphere.
