_The Martindale Box for Lepidoptera._--Mr. Isaac C. Martindale, in the October, 1891, number of _Entomological News_, pp. 126, 127, describes a new form of cabinet for butterflies, the drawers of which present some new features. They are for the same end as the Lintner box described above--namely, for the display of the upper and under surface of the wings of Lepidoptera, and promise to be more useful. The drawer is described as follows: The especial feature is the drawer itself, which, instead of having a cork bottom, as is usually the case, has both the top and bottom of glass. The top part of the drawer frame fits tightly over a ledge one inch in height, effectually preventing the intrusion of destructive insects, the pest of the entomologist; but it is readily lifted when it is desirable to add to the contents or change the location of the specimens. For the inside arrangement I have taken a strip of common tin, one inch wide, and turned up each side five-sixteenths of an inch, thus leaving three-eighths of an inch for the bottom. The length of the strip of tin, being about two inches longer than the width of the drawer, admits of each end being turned up one inch. Into this tin trough is tightly fitted a cork strip three-eighths of an inch square. The whole being covered with white paper, such as is usually used for lining drawers, conceals the inequalities of the cork and makes a fine finish. They should be made to fit neatly in the drawer, and can be readily moved about to suit large or small specimens. For _Lycaenas_, _Pamphilas_, etc., as many as fifteen of these strips may be used in one drawer, and as few as five for _Morphos_, _Caligos_, etc. The upturned ends are fastened in place by using the ordinary thumb tacks that can be procured at any stationer's. The frame work of the drawers should be of white pine, well seasoned. Into this the thumb tacks are readily inserted and as easily withdrawn when a change in the position of the cork strips is needed. _Horizontal vs. vertical Arrangement of Boxes._--I have elsewhere discussed the availability of the upright vs. the horizontal arrangement of insect boxes.[9] In the case of Lepidoptera and large-bodied insects I have found the horizontal drawer or box to be preferable. If large-bodied insects are placed in a vertical position they are very liable to become loose on the pins, swing from side to side, and damage themselves and other specimens; but for the smaller insects of all orders, the vertical arrangement is quite safe and satisfactory. If the pin is slightly flattened, as described on p. 69, the danger of large specimens becoming loose is to a great extent avoided. [9] _American Naturalist_, Vol. XV, p. 401, 1881.
