manner to be defcribed under the next clafs for 

 killing moths. 



III. The divifion of butterflies and moths (le- 

 pidoptera) as well as all flies with thin mem- 

 branaceous wings, ftiould be catched with a 

 gauze net, or a pair of gauze forceps : (fee 

 pi. i, fig. 2) when taken in the forceps, run a 

 pin through the thorax or moulders, between 

 the fore-wings, as in frontifpiece, fig. 3. After 

 this is done, take the pin by the head, and re- 

 move the forceps, and with the other hand 

 pinch the breaft of the infect, in order to de- 

 prive it of fenfation and life : the wings of but- 

 terflies mould be expanded, and kept fo, by the 

 preffure of fmall flips of paper, for a day or two. 

 Moths expand their wings when at reft, and 

 they will naturally take that pofition. 



The larger kinds of thefe infects will not fo 

 readily expire by this method, as by flicking 

 them upon the bottom of a cork exactly fitted 

 to the mouth of a bottle, into which a little ful- 

 phur had been put, and by gradually heating the 

 bottle till an exhalation of the fulphur takes 

 place, when the infect inftantly dies, without 

 injuring its colours or plumage. 



Perhaps the molt eafy method of killing moths 

 and butterfliesis by means of aneedlemade of fteel 

 fixed in an ivory handle, which muft have palfed 

 hroughthe body of the moth; the thumb and fore- 

 finger of the left-hand muft be inftantly placed 

 on each fide of the cheftof the moth, jufl under 

 the wings, when a fqueeze will entirely deprive 

 the infect of motion, and probably of fenfation 

 too for fome minutes ; thefe, however, will re- 

 turn
