11 m op t e ra. — 

 The Cicadas and 

 other species witli 

 large mesothorax 

 should be pinned 

 through this part ; 

 others may be 

 pinned between 

 the bases of the 

 wings, and some 

 (if unset) through 

 the base of the 

 right wing. 



HOMOrTEUA. 



When pinning Hymenoptera and Diptera, it is 

 very useful to use circular card discs of about 

 I inch in diameter, upon the under side of which 

 the locality, date of capture, etc., can be written. 

 After the insect is pinned, the pin is passed through 

 the middle of the disc until the insect is within a 

 short distance of the card. By this method the 

 legs are not only protected and prevented from 

 hanging down, but they can be spread out so as 

 to be ready for examination.
