PLATE XII. — Method of Settinc Insects. 
Fig. 1. Opilis mollis (p. 166).— This figure exhibits the method ot set- 
ting Coleoptera with the wings closed and in a crawling position ; 
the legs are kept in the attitude designed by pins applied as ne- 
cessity requires ; the tarsi are kept flat on the setting-board by 
card-braces, as at b. — Care must always be taken to introduce the 
pin whicli serves to transfix the insect, through the right elytron. 
Fi<r. 2 . Callidium bajulum with the elytra extended and the wings dis- 
played; in all specimens set in this way the pin must be passed 
through the middle of the back and near the thorax : the wings are 
kept extended by braces. 
The above methods are also applicable for the Orders Dermapteru, 
Orthoptera , Diclyoptera, Hemipteru and Omoptera. 
Fig. 3. Odeuesis potatoria (p. 247). The method ot setting the Lepi- 
doptera is fully explained at 320. 
Fig. 4- Sjratiomys Chamadeon (p. 292). Neuroptera, Th/menoptera, as 
° well as Diptera, may be set by pins alone as is here exhibited. 
Fig. 5. Such minute insects as are difficult to pierce with a pin may he 
placed on small triangular pieces of paper: this method is to be 
preferred, as almost every part may be examined, and is much su- 
perior to the method frequently used, as at fig- 0.
