or a pair of forceps covered with gauze. When 

 they are taken, flick a pin through the middle 

 of one of the hard wings, and pafs it through 

 the body, as in plate, fig. k; They may be 

 killed inftantly, by immerfion in hot water, as 

 well as in fpirit of wine ; then Itick them on a 

 piece of cork, and afterwards carefully place 

 their legs in a creeping pofition, and let them 

 continue expofed to the air until all the moifture 

 is evaporated from their bodies. Beetles may 

 alfo be preferved in fpirit of wine, brandy, or 

 rum, clofely corked up. 



II. Infects of the fecond clafs (hemiptera) 

 may be killed in the fame manner as beetles, and 

 likewife by means of a drop of the etherial oil of 

 turpentine applied to the head ; or in the man- 

 ner to be defcribed under the next clafs for 

 killing moths. 



III. The divifion of butterflies and moths 

 (lepidoptera) as well as all flies with thin mem- 

 branaceous wings, mould be catched with a gauze 

 net, or a pair of gauze forceps : when taken in 

 the forceps, run a pin through the thorax or 

 Ihoulders, between the fore-wings, as in plate, 

 fig. 3. After this is done, take the pin by the 

 head, and remove the forceps, and with the 

 other hand pinch the breaft of the infect, and it 

 will immediately die : the wings of butterflies 

 fhould 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 flickino-

 to the mouth of a bottle, into which a little
