An insect collection should-contain some identification labels. How these are best arraneed will deoend on the size of the collection and the extent to whiah it is ideniifed. Most collections should be labeied at least to order and {amiiv. and the soecimens so aranged that a sing'e label can se.ve I'or all t\r specinens in a group. When specimens are labeled to species, an identiication label is placed on each specimen or on the first in a group. This label is a plain piece of paper (about an inch square and at the base oI the pin) containing thc scientific name oI the insect, the name of the person identifying it, and the date (month and year) the identihcation \r'as made. Bores for Pinned Insects. Pinned insects are kept in bores having a soft material in the bottom to pcrmit casy pinning; they can be obtained from a supply house or be homemade. f'he most common supply house type is a Schmitt box, a wooden box about 9 x 12 x 211 in. \\.ith a tight-litting lid and the bottom lined with sheet cork or similar material. Such boxes cost from a few to several dollars. Similar boxcs made ol heavv cardboard are available from suoolr hou,e, anJ cr,,r on. hcll io orc rhicrl as mu, h. Homcmade bo*6s -ay be made of rvood or heavy cardboard, and the bottom lined rvith sheet cork, balsa wood, Styrofoam, or corrugatcd cardboard. The material in the bottom should 1it tightly, and if corrugated cardboard is used it should be soft enough to take an insect pin. Large collections ma1' be housed in Schmitt boxcs, or in cabinets contairing trays or drarvers constructed like Schmitt boxes, Riker Mounts. A Riker mount is a glass-topped box containing cotton, with jnsccts on the cotton just under the glass. Insects spread lor mounting jn a Riker mount are spread in the upsidedown position descrihed on p. 15. Riker mounts may be of various sizes, and also can be purchased from a supply house or he hom"- A8 The Riker mount.
