Below the groove a strip of cork should be glued to hold the pin which has been put through the central portion of the thorax of the insect. When mounted, the insect should be high up on the pin, about one fourth of the pin above the specimen. The wings of butterflies and moths should be arranged as shown in fig. 4, the lower margins of the front wings forming as nearly as possible a straight line. With fine needles the wings can be brought forward and held in place by strips of writing paper or thin cardboard. No. 00 insect pin cut in two and the blunt end forced nearly all the way into half a match, makes a splendid setting needle. These pins are very fine and when used carefully to pierce the wings to hold them m position, the holes made are so small that they are practically invisible afterwards. Specimens should be kept on the spreading board at least a week or ten days, and the boards may be hung in rows on a wall, if a hook of some kind is screwed into the top of each. If it is not convenient to mount the specimens immediately alter their capture, these can be put in envelopes and then stored away in a tin box until the opportunity arrives when they can ^^^^^^^ of folding paper for be relaxed and spread. Fig. 5 shows envelope. First fold on the line the pattern of envelope used by ento mologists for papering their captures.
