This case can be made by anyone having some skill with car- penter's tools, and if well constructed is very rarely troubled by pests, the lead apparently being obnoxious to them. For the display of butterflies and moths, a larger case, preferably a horizontal tray, is desirable. In adopting a large drawer it is well to select a size uniform with those used in museums and to insist on the trays being interchangeable. One of the best insect cases is the form adopted by the late Dr Riley for the United States national museum. It is cm (18 in.) square and has an outside depth of cm (3 in.). The sides and back are .9 mm (f in.) and the front of cm (| in.) stuff, while the bottom is composed of three ply cross-grained veneer in order to prevent checking. The back and side pieces are dovetailed and the bottom fitted into a groove. Inside of the outer frame is a secondary box of 3 mm {^ in.) whitewood, closely fitted and held 6 mm {I in.) from back and sides and 9 mm (f in.) from the front by blocks. The space between the two boxes is used for insecticides, usually naphtha- Hne, and the 6 mm Q in.) tongue of the cover, a frame cm (|^ in.) wide and 9 mm (| in.) thick holding a single thick glass, fits tightly into the space between the outer and inner box. The first lot was made of California redwood with a cover frame of mahogany, but those made later are of cheaper materials ; basswood or whitewood is good. These trays are made to slide on a groove. The outside of the case may be left its natural color, but the inside should be
