[42] the extremely quick fliglit of these insects, the removing of Hymen- optera from the net is not always an easy task, and in many cases rare specimens escape. One method of avoiding the danger of being stung is to have the collecting net constructed with an opening at the bottom which, during the sweeping, is tied with a string. When a sufficient quantity of insects is obtained they are, by a few quick motions, driven to the bottom of the net, and the net is then seized just above the insects with the hand, the folds of cloth preventing the insects from getting to the hand, so that there is little danger of being stung. The lower end is then care- fully untied and in- serted into a wide- mouthed bottle, and the contents of the net shaken out into the bottle. After the catch is stupefied the vial may be turned out and the undesirable material dis- carded. A second method consists in the use of an ordinary sweeping- net of light material. A quantity of Hymenoptera are collected from flowers and driven to the bottom of the net, and secured as in the pre- ceding method. The portion of the net containing the insects is then, by means of a pair of forcej)S, thrust bodily into a large collecting bot- tle. After a few minutes the insects are stupefied and may be readily Tig. -The Little Eed Ant (Monomorimn pharaonis). a, female; &, worker enlarged. COLLECTING COLEOPTEEA. General Directions.—Owing to their hard outer skeleton, Cole- optera can be collected, handled, and j)reserved with greater safety and with less trouble than most other orders of insects. From this fact, and from their very great diversity in form, Ooleoptera have, next to the Lepidoptera, always been favorites. As a consequence, there are now more species described in this than in any other order, and in the large museums they are much better represented than other insects. This rich m
