iNSTRtJCTlOKS TOK. 



Coleoptera, Hemiptera, Orthoptera, and other non-hairy insects 

 may be killed by throwing them into boiling water ; but they must 

 be taken out as quickly as possible, and placed on blotting-paper to 

 drain off the water. 



Lepidoptera may be killed in the cyanide-bottle, and then pinned 

 into the zinc collecting- box, where they can i-emain in a relaxed 

 condition until it is convenient to set them. 



Butterflies may be killed by pinching the thorax laterally while 

 the wings are in an upright position ; but although this is necessary 

 sometimes, it requires to be done with care, ns it is apt to distort 

 the body and render the specimens difficult to set. 



Pinning and Mounting. 



Hymeyioptera, Diptera^ Lepidoptera^ and 

 Neuroptera should be pinned through 

 the middle of the thorax. The position 

 of the pin is indicated in the illustrations 

 by a black dot. 



HYMENOFiKRA, 



Coleoj)tera should be pinned through the 



right wing case near the base, and in such 



. a way that the pin comes out below behind 



\ the middle pair of legs. As a rule the pin 



should be equally distant from the base and 



the side of the wing-case. 



COLEOPTKRA.
