The CHRYSOPHIDES comprise the lace wings known as “Ruby Eyes” from their rich metallic tint, or “Aphis Lions” on account of the voracious habits of their larvae. They hide among the foliage in the day time, and in summer often come buzzing round the lamp, several species giving out a most objectionable smell when handled. They are generally slender-bodied green or yellow insects with large delicate glassy wings, folded over the back. They attach their eggs to the foliage on long slender stalks, probably a means of protection against other larvae that might otherwise find and devour them. The larvae are active little creatures with large heads furnished with scythe-shaped jaws; their rounded backs are covered with short stiff hairs, by means of which they hold bits of dirt, sand, or wood, with which they cover themselves when feeding upon the aphids or scale. If when in captivity these bits are brushed off they run round and replace them bit by bit; pushing the bits into the jaws with their fore legs, then turning their heads backward, they drop each bit upon their backs, repeating the operation until they are again completely covered. When full-grown they spin a white hemispherical cocoon composed of fine white threads and the longer hairs of the body, from which in summer the perfect insects will emerge in a fortnight.

Larva; stalked egg; and pupa enclosed in hemispherical cocoon covered with the remains of the aphis upon which it has fed during the larval stage.] The Green Lace Wing, _Chrysopa ramburi_, is our common orchard friend; and where plentiful they soon clean the trees of aphid and scale insects. Its general colour is bright green fading into yellow after death; the large golden eyes are so bright that they can be seen through the cocoon some time before it emerges. The Brown Lace Wing, _Micromus australis_, is common among dead bushes, and also in summer in orange orchards; it is much smaller than the last, only slightly over ¼ of an inch across the expanded wings; is of a general light brown colour mottled all over the wings with darker tints. The broad head is furnished with large bronzy eyes, and slender hairy antennae composed of 44 very short annular joints. Both the slender, brown, ferret-like larvae and the perfect insects are very active little creatures, always on the move. This species was described by me in the Agricultural Gazette N.S. Wales, 1904. Family 7. Caddis Flies. TRICHOPTERA.
