COLLECTING INSECTS.

OrtJioptera should be pinned in 

 the middle, between the bases of 

 the wings. Of course, if they are 

 pinned without being set, the pin 

 must pass through the wings; in 

 which case it is better through the 

 right wing. In some instances the 

 pronotum is produced backwards, 

 so as to cover a great part of the 

 body ; in which case the pin must 

 necessarily pierce this part. In 

 most cases it is desirable to have 

 specimens pinned in both ways. 



Hemiptera should as a rule be pinned through the 

 right wing in the same way as Coleoptera ; but 

 where the\scutellum is large, it is necessary to pierce 

 this part a little to the right of the centre, so as to 

 avoid any central spot or mark. When the wing^ 

 are set out, the pin may be in the centre.
