without any external injury, by being immersed in boiling 

 water. When dead, the Insect should be stuck through with 

 a pin of the proper size, close to the suture that runs dowa 

 the middle of the back, so as to make the pin pass a 

 sufficient length through the body, and then secured on a 

 piece of smooth cork, their legs and horns are to be placed 

 in a natural position, by means of a pair of forceps, or fine 

 tweezers, and should be kept so by the assistance of 

 thin pieces of card-paper, as more fully directed for the 

 class Lipedoptera ; in which state when dry^ they will ever 

 afterwards remain ; care should be taken not to place them 

 in the store box, till thoroughly dry ; indeed it would be 

 well to place all insects in a gently heated oven, of such a 

 temperature, that when a hair or feather is placed within, it 

 will not curl up. Many of the Beetles are furnished with 

 beautifully veined wings, which, when carefully dis- 

 tended, add much to the interest of a collection, these 

 wings, which are curiously folded together, beneath the 

 shells or horny covers, should be carefully drawn out with 

 the forceps, and kept so with slips of card paper, as repre- 

 sented at A plate 3. It frequently happens, that Insects 

 received from abroad, arrive in this country in a very bad 

 state, with regard to setting, this may be rectified by 

 placing them within the influence of steam for a short 

 time, when their wings and legs will become flexible, and they 

 may then be adjusted, as in recent specimens. 



The Insects in the class Hemiptera, may be killed either 

 by emersion in boiling water, or with a few drops of spirits 

 of turpentine, and they should be set in the same manner as 

 the preceding class. Many of the genera are found in 

 fields, meadows, and on the leaves of tree:-, as the Mantis j
