mens from lc( oming infested with the eggs of dermestids and 

 other museum pests Small cleats tacked at intervals on the in- 

 side will serve to support the pasteboard trays. After drying 

 for a week or so the specimens can be transferred to permanent 

 cabinet boxes, which should be as nearly dust-proof as possible. 



Earwigs, small crickets and other minute forms should be 

 mounted (as is the beetle in Fig. 24) with transparent glue or 



shellac on the tip of a small narrow triangu- 

 lar card through the base of which a pin has 

 been run. Only a very small amount of the 

 glue is necessary, it being most readily ap- 

 plied to the card with the tip of a wooden 

 toothpick. The legs should be carefully 

 spread before mounting and the body then

MUSEUM PESTS. On account of their bulky bodies Orthoptera 

 are especially subject to the attacks of museum pests. Flakes of 

 napthaline kept in each box will usually serve as a repellant for 

 such pests. Each box should be examined three or four times 

 a year, and if by dust, exuvia or other debris, the presence of 

 pests is indicated, a few drops of carbon bisulphide should be 

 poured in the box and the lid quickly closed. The vapor of this 

 will soon destroy the eggs, larvae or other living form of any pest.
