remarkiiijjf that its venation is typicallj- Tineinan. He adds tliat in shape and mode of life the 

 females of many species of Funiea, and those of Ejiichnopteryx and of the Tahepoiida^, are much 

 more nearly related to each other than tliose of other species of Funiea and I'syche the species 

 of the latter genus falling into two groups, 

 judging by their venation, and he states that 

 r.stichc fcbrettd is ''the nearest relation of 

 the type fmm which on the one side the 

 Zygienidic and on the other tlie Arctiida> and 

 Liparida' have descended. Tiie Lithosiidai 

 are also perhaps to be added, and indeed 

 belong to a branch which extends from the 

 Taheporidie to the Crambidte and Phycidje.*' 

 From an examination of the pupa, and also 

 the statements of Chapman and of Com. 

 stock, it is evident that the Psychida^ should 



be removed from 

 the Pombyces and 

 jilaced among the 

 Tineoid moths. 



It isevidentthat 

 tlie line of develop- 

 ment from the nar- 

 row tineiil- winged 

 Tahcporidic to the 

 broad ■ winged Psy- 

 chida' was nearly 

 direct. Perhapsthe 

 slight changes in 

 venation and nuicli 

 greater breadtli of 

 the wings and the 

 pectinated antennte 

 are the result of 



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

 ac(iuiring greater power of extended flight and a more acute sense of 

 smell in order to discover the presence of the females. 



In comparing tlie pupa' of different genera ofPsychidre with those 

 of the TaLcporida', the resemblance is most striking 

 and naturally suggests the direct evolution of the 

 Psycliids from the latter group. The head is broad 

 and has the same general sliaiie as in the Tahejioridie, 

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

 however, in the I'sychidre is more distinct from the clypeus, though in 

 Solotohia u-al.shella it is nearly as separate. 



The shape of the cases of the maxillary palpi of Psyche {/raminella, 

 {(Eccticus ahhoiii, flg. 28), and 2letrua clonf/aia is as iu Solenohia icahhclla 

 and *S'. pineti. The maxilhe {m.i\), fairly well developed in the Psychida^, are 

 much as in Solcitohia icalsliella. The labial palpi (whr'.^j.), though ^arying 

 much in the different genera of Psychida^, are essentially as in the Talwpoiida: 

 Compare those of Psyche, GEceticus, and Entometa with those of Talcvporia 

 pscHdoliomhyceUa. Those of IMato'ceticus are longer tlian in tlie other Psy- 

 chida% but still more rudimentary than iu Soleiiobia. In regard to the shape of the maxillary 

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

 I'S), m.v.p.) differs fron other Psychidie and approximates to certain Hepialidte (fig. 33).
