the whole of the paper. Males and females should 
be placed together if they can be had; and if pos- 
tible two specimens of each, for the purpose of 
exhibiting both the upper and under side. If the 
insect is subject to variety, these should also be

The wings of lepidopterous insects should be ad-

The larger insects of this order are set by braces
