INSTRUCTIONS FOR 
Ilomoptera .—- 
The Cicadas and 
other species with 
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. 
HOMO PTE RA. 
When pinning Hymenoptera and Diptera, it is 
very useful to use circular card discs of about 
| 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. 
USE OF DISCS.
