Only females could be reared from these larvae. The case of Chalia hockingii (Fig. 19 7, C) consists of little pieces of wood cut to the proper lengths, and spirally arranged, so as to form a construction that would be quite a credit to our own species. In some of the Cauephorinae we meet with long cylindrical cases, like those of Caddis-worms, or of Tineid larvae. Pdley has given an account of several points in the struc- ture and natural history of one of the ISTorth American basket- or bag-worms, Thyridopteryx ephemeraeformis; one of his points being the manner in which the newly hatched larva forms its case.^ This question has also been discussed by Packard.^ The larvae when hatched in unnatural conditions will make use of fragments of paper, cork, etc., for the case ; the act of construc- tion takes one or two hours, and the larva does not eat till the case is completed. It walks in a peculiar manner, the legs of the third pair being moved forwards together, as if they were the prongs of a fork. This family is already one of considerable extent, but its study, as already remarked, is but little advanced. Some naturalists are inclined to place it among the Tineidae, but it is connected with Zygaenidae by means of Heterogynidae. Mr. ileyrick divides it, placing Psyche and Sterrhop)teryx (the forms representing, according to his ideas, the family Psychidae in Britain) in the series Psychina which includes Zygaenidae.
