The golden-eyed lace-winged (lies are .imonn the most im- portant enemies of the injurious plant-lice which swarm upon many valuable plants especi;;'lv in the early part of the xummer. The mother tly lays her ejjfjs where possible in the midst of colonies (if plant-lice, and these arj rapidly swept. lut of existence after the eggs are hatched. A few of these lace-winged tly larvx have the same habit which we have described .is occurring with the Hemerobiids, of covering themselves with the skins of their victims. Hubbard studied a species which feeds upon bark-lice, tearing the scales loose from the bark and devouring the solt contents, and then .aiding a portion of the debris to the load on its 1 ack. Unfortunately, these beneticial lace-winged Hies are subject to the attacks of certain parasitic chalcis flies which sting their cocoons. Trie species of the interesting lienus Isodromus seem to confine their attacks exclusively to the cocoons of lace-winged Hies. ii rr. Life History of a Golden-Eye (Clirysopa oculala Say.^ This is one of the commonest species in this group, and is often mentioned in books on economic entomology as destroying plant-lice and other injurious insects. The only observer to de- scribe its life history with .my detail, however, is ., from whose observations the following statements are drawn. The eggs, of being deposited in rather large groups, as is the case with other species, are distributed almost invariably sing
