A Panorpa, or scorpion-fly, and its larva. what like the sting of a scorpion, and from this the common name is derived. As a matter of fact, the insects are entirely harmless save to others of their kind, for they are predaceous. The genus Bittaais is narrower winged, with unusually long legs, looking somewhat like a crane-fly at first sight. Species belonging to the genus Boreus occur on the snow in very early spring. The larvae, so far as we know them, are predaceous and resemble caterpillars in appearance ; they have eight pairs of fleshy prolegs, however, while no true caterpillar ever has more than five. None of the species are common and none are of practical importance to the farmer. The " caddice-flies" have also been elevated to ordinal rank under the name Trichoptera, or " hairy-winged." The adults have moderately developed bodies, with large wings, which are more or less densely clothed with hair, the first pair often thicker
