AUSTRALIAN LEPIDOPTERA 

 VSY GillDM. 



The great divisional character wliicli parts' into two the family of the Psychiflm appears to consist wholly in the form 

 which tlic females assume at their final development : wliether they hecome possessed of wings or remain in an apterous state. 

 This simple arrangement, so ably illustrated by Mr. Walker in the Catalogue of the British Museum, enables us to compare, 

 without difficulty, our Australian examples of the -Toemina alata," with the only three genera of ^vinged females (contammg 

 together but 12 species) mentioned in the Catalogu.! ; and to point out more clearly and easily why we have deemed it advisable 



to create the following new genera. 



The males of two out of the throe genera described, viz., the Typhonia and Pcrophora, have pectinated antenna;, while 

 those of our insects are ciliated, and although the antenna; of the only species of the remaining genus, the Psychoides, are 

 sub-ciliated, stUl its larva occupies a fixed habitation while those under consideration dwell in portable eases. Keeping in 

 view these essential distinctions, wo feel justified in separating our insects from those described in the Catalogue ; and with 

 respect to themselves reasons for their division will be introduced in each generic description. We may further remark that 

 the PsychidM are numerous in this country, and, judging from the many examples which have passed under our notice, the 

 class containing the winged females is fully equal in number to that of the wingless ; and that the antonn:e of the males of the 

 former are found as yet invariably to be ciliated, while the reverse in both instances appears to be the case in all the genera 



hitherto described. 



In concluding those preliminary observations, we may bo permitted to express our gratification in being enabled by the 

 production of the ensuing throe now species, to name them in honour of the following scientific and esteemed naturalists, viz., 

 the late llov. Landsdown Guilding, of St. A^inoent's, author of numerous valuable entomological papers ; Dr. George Praucnfeld, 

 the present learned Curator of the Imperial Museum at Vienna, whoso friendship we acquired in this country during his tour 

 as Naturalist to the Imperial Austrian Expedition ; and Dr. C. Eelder, of Vienna, one of the authors of the meritorious 

 publication " Lepido])terologischo Eragmento" and other works. 



The fourth insect in Plate 9, the (Ecinea Sootti, was named after ourselves, by the eminent entomologist William Sliarpe 

 MacLeay, Esq., to whom we arc also indebted for many other acts of kindness.

Females winged. Wings in both sexes elongate, narrow, lanceolate, very slightly rounded at their tips, exterior borders 

 very oblique, and hinder angles much rounded. Abdomen extending beyond the hind wings ; in the male attenuated and 

 aeiuninated at the apex ; in the female robust and rounded, with longish hairs on the ultimate segment. Head very small. 

 AntennsE rather long; «K(/e~-articulations produced beneath, somewhat resembling serrations, each being furnished with a 

 ciliated tuft : /c»ia/e— filiform. Palpi very small, terminal joint minute and pohited, nearly naked ; 2nd and basal joints 

 nearly equal, both being longer than the terminal and slightly pilose. Legs small, graduating in size, the posterior being the 

 largest ; tibia; and tarsi sparingly clothed with hair-like scales ; 2nd pair with 2 and posterior with 1 longish spurs on tibioe. 

 Larva thick, fleshy ; abdominal portions naked, thoracic corneous. Case more or less cone-shaped, carried principally upright, 

 open at both ends, composed of silk thickly covered with fine particles of bark or grains of sand.
