794 The American Naturalist. [September, 
as we have seen, it is not so generalized a group as the Microp- 
terygide, a group common to Europe and North America. 
Its relations to the Cosside, including the Zeuzerine, remain 
still to be elaborated ; they are rather close, yet the Tortricoid 
affinities are very apparent, and need further examination. 
The pupa of Zeuzera. pyrina is of the same character as in Pri- 
onoxystus, but the maxillary palpi are larger, the lateral palpi 
more reduced, while the cell-breaker is very long, being much 
more developed. 
Family Taleporide—This group, comprising the genera Sol- 
enobia and Taleporia, have evidently either directly descended 
from the case-bearing Tineide or the two families have had a 
common origin. They form a side branch by themselves and 
are evidently the immediate ancestors of the Psychide. The 
imagines have no maxillary palpi, and the tongue is wanting, 
whilst the females are wingless. They are tineid Bombyces. 
In the pupal characters (Fig. 10, Talxporia pseudobombycella, 
pupa, A, head enlarged ; B, end of body) the group very closely 
resembles the Psychide. Perhaps the slight changes in vena- 
tion and the much greater breadth of the wings, as well as the 
pectinated antenne of the Psychide, are the result of adapta- 
tion to the stationary mode of life of the females (Fig. 11, Sol- 
enobia walshella, head of pupa; A, end of body). 
Family Psychidey.—An examination of the pupæ of several 
genera of this family, convinces me that it belongs among the 
Tineoids, and that Chapman and also Comstock have rightly 
removed them from the Bombyces. I should place them in 
the neighborhood of the Tineoid genera Solenobia and espe- 
cially Taleeporia, the venation of the latter genus being, as 
shown by the figures in Spuler’s* paper, almost identical with 
that of Fumea and Psyche. Without, at this time, referring 
to the larva of the highly modified wingless female, or to the 
characters of the adult male, I will simply call attention to 
some points in the structure of the pupa of different genera of 
the group, which indicate their very generalized nature. 
The pupa of Thyridopteryx ephemerexformis has a close resem- 
blance to that of Oncopera intricata, as will be seen by the pres- 
ence of a large median piece or area between the base of the
