remarking- tliat its venation is typically Tineinan. He adds tliat in shape and mode of life the 

 females of manj- species of Funiea, and those of Epichnopteryx and of the Taheporidse, are much 

 more nearly related to each other than those of other species of Fumea and Psyche the species 

 of the latter genus falling into two groups, 

 judging' by their A'enation, and be states that 

 Fsyche febretta is '-tlie nearest relation of 

 the type from which on the one side the 

 Zyga'nidiB and on the other the ArctiidiC and 

 Liparida^ have descended. The Lithosiidie 

 are also perhaps to be added, and indeed 

 belong to a branch which extends from the 

 Tala'porid;e to the Orambidai and Phycidic.'' 

 From an examination of the pupa, and also 

 the statements of Chapman and of Com. 

 stock, it is evident that the Psychid;e should 



be removed from 

 the liombyces and 

 placed among the 

 Tineoid moths. 



Itisevidentthat 

 the line of develop- 

 ment from the nar- 

 row tiueid-winged 

 Taheporidffi to the 

 broad ■ winged Psy- 

 chid;e was nearly 

 direct. Perhapsthe 

 slight changes in 

 venation and much 

 greater breadth of 

 the wings and the 

 pectinated antennie 

 are the result of 



adaptation to the stationary mode of life of the females, the males 

 acquiring greater power of extended flight and a more acute sense of 

 smell ill order to discover the presence of the females. 



In comparing the pupa' of different genera ofPsychid;ie with those 

 of the Tala'p()rid;e, the resemblance is most striking 

 and naturally suggests the direct evolution of the 

 Psychids from the latter group. The head is broad 

 and has the same general shape as in the Tala'])Oii(he, 

 including the form of the eyes, of the clypeus and of the labrum, which, 

 however, in the Psychidiie is more distinct from the clypeus, though in 

 Soleiiobiit iralshclla it is nearly as separate. 



The shape of the cases of the maxillary palpi of Psyche (/rnminclld, 

 (GSceticus abbotii, fig. 28), and Metriia elonflata is as in Soleiiobia icalshella 

 and 8. pineti. The maxilhe {m.r.}, fairly well developed in the PsychidiP, are 

 much as in Soleiiobia icalsIicUo. The labial palpi (ww'.jj.), though varying 

 much in the different genera of Psychid:T», are essentially as in the Tahrporida: 

 Compare those of Psyche, QSceticus, and Entometa with those of TaUvporia 

 pscndobombyceUa. Those of Platfeceticus are longer than in the other Psy- 

 chidie, but still more rudimentary than in Solenobia. In regard to the shape of the maxillary 

 palpi, AFhich unite, forming a continuous bar or piece in front of the labrum, Thyridopteryx (fig, 

 29, m.r. p.) differs from other Psychid;e and approximates to certain Ilepialida' (fig. 33)..
