. Elementary lessons on insects . <\ T Fig. 66.—Odd ways of pinning insects: A, a fleabeetle pinned (as is the rule for beetles) through the right wing cover; B, a gall midge mounted on a pin point; C, a snout beetle glued to a paper point. When removed from the cyanide bottle they may be pinned at once; and best so, if time permits. When once they have become dry and brittle, they have to be relaxed before they can be pinned. The relaxing jar commonly used for this purpose is a two-gallon jar of glazed earthenware containing damp sand over which clean papers are spread.
