To set a beetle, pin it through the right elytron (wing case) with an entomological pin, raising the body high enough to give sufficient space for the proper arrangement of the legs. The beetle is then pinned to a flat piece of cork, and the legs arranged, each joint of the legs being kept in position with common pins. Pins are also used to display the antennse, and the specimen is then left for a few days to dry. When dry, the common pins are withdrawn, and the beetle is removed to the specimen drawer and pinned down on a card bearing its common and its scientific name. Beetles may also be set with gum. On a piece of card drop a little gum where the legs of the beetle are likely to come. Pin the beetle upon the card, and draw each leg into position and keep it there till the gum has set. Then put the specimen away to dry- The gum is afterwards dissolved, and the beetle set free, by soaking in water. Each foot is then gummed, and the insect is placed upon a clean card. It is advisable to kill the beetles as soon as caught, as some specimens are likely to be damaged by1 long captivity. If, however, they must be kept alive till home is reached, each specimen must be kept in a separate bottle, tube, or box.

If kept together in one receptacle, they will not only damage each other in their efforts to escape, but the carnivorous kinds will devour the others.
