Lepidoptera, and other insects with broad and flat- tened wings, should have their wings spread. This can be accomplished with the aid of a spreading-board. This board is made of two pieces of thin pine boards laid parallel and fastened by braces at the ends, and if the boards are long there should be a center brace. There should be enough space between the boards to admit the bodies of the insects to be spread. This space. FIG. 186. Spreading-board for Lepidoptera. between the boards should be covered from beneath with sheet cork or corn pith, to hold the pin upon which the insect to be spread is mounted. The braces should be high enough to allow the pins holding the insect to pass through without touching the supporting-table. To spread the insect, first pin through the rnesothorax, then place firmly in spreading-board, by the pin pass- ing through the cork or pith.
