remarking that its yenation is typically Tineinan. He adds that in shape and mode of life the 
females of many species of Fumea, and those of Epichnopteryx and of the Talaeporidfe, 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 venation, and be states that 
Fsyche febretta is ‘‘the nearest relation of 
the type from which on the one side the 
Zygienidm and on the other the Arctiidm and 
Liparidm have descended. The Lithosiidm 
are also perhaps to be added, and indeed 
belong to a branch which extends from the 
Tala'poridm to the Crambidm and PhycidiU.’’ 
From an examination of the pupa, and also 
the statements of Chapman and of Com. 
stock, it is evident that the Psychidm should 
be removed from 
the Bombyces and 
placed among the 
Tineoid moths. 
Itisevidentthat 
the line of develop- 
ment from the nar- 
row t i 11 ei d - w i n ged 
Taheporidic to the 
broad- Avinged Psy- 
cbidm was nearly 
dire ct. P erh a p s th e 
slight changes in 
venation and much 
greater breadth of 
the wings and the 
X)ectiuated antenum 
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 in order to discover the presence of the females. 
In comparing the pupm of difterent genera of Psychidm with those 
of theTalaqioridie, 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 Talreporida?, 
including the form of the eyes, of the clypeus and of the labrum, Avhrch, 
however, in the Psychidm is more distinct from the clypeus, though in 
Solenohia tcalsliella it is nearly as sei^arate. 
The shape of the cases of the maxillary palpi of Psyche gramrnclla, 
{(Eceticus ahhotii, fig. 28), and Metrua elongfttn is as in SoIenoMa icalshcUa 
and S^pineti, The maxiihe (?n,r.), fairly well developed in the Psychidai, are 
much as iu SoJenohia icalsheJla, Tlie labial palpi though varying 
much iu the different genera of Psychidie, are essentially as in the Talaporida\ 
Compare those of Psyche, (Eceticus, and Entonieta Avith those of Takvporia 
pseudobombyceUa, Those of Platoeceticus are longer than in the other Psy- 
chidre, but still more rudimentary than iu Solenobia. In regard to the shajAe of the maxillary 
palpi, Avhich unite, forming a continuous bar or piece iu front of the labrum, ThyridoxAteryx (fig. 
29, differs from other Psychidm and axAproximates to certain Hex>ialidie (fig. 33).
