These are case-making moths. The females arewingless, the legs, antennee, and organs of the mouth,being almost entirely obliterated. A few small speciesare found in this country. One, Oiketicus niyricans,occurs in the New Forest. We give a figure of thecases constructed by this insect in its larva state—Fig. 102, p. 2G4. They are found attached to and gorse in May, when the moth silky texture, and strengthenedor protected by the addition ofpieces of stick. At the lowerend is a flexible aperture,through which the excrementis discharged. Through a tubeat the upper end the larvacomes out to feed. Thesecases are attached to variousshrubs. Similar cases are foundin South Africa. The generations of the femalePsychidse have been observedto succeed each other, withoutthe production of or access tothe winged male,through sevensuccessive years.—(SeeSieboldon Parthenogenesis.) Want ofspace will not allow of furtherreference to the genera of thisfamily. F.\5nLY-N0CTUID^. This is the most extensive ofall the families of Lepidoptera,and to it belongs the bulk ofthe night-flying moths, andthey are consequently aptlynamed Noctuidce. In thiscountry alone upwards of
