PLATE XIL — Method of Setting Insects. 



Fig. 1. Opilis mollis (p. 166).— This figure exhibits the method of 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 h. — Care must always be taken to introduce the 

 pin which serves to transfix the insect, through the right elytron. 



Fig. 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 Dermuptera, 

 Orthoptera, Dictj/optera, Hemiptera atul Omoptera. 



Fig. 3. Odenesis potatoria (p. 247). The method of setting the Lcpi- 

 doptera is fully explained at 320. 



Fig. 4. Stratiomys Chamaeleon (p. 292). Neuroptera, Hi/tnenopteru, 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 be 

 placed on small triangular pieces of paper : this method is to he 

 preferred, as almost every part may be examined, and is much su- 

 perior to the method frequently used, as at Jig. 6,
