Fore-wings, elongate, widened outwardly; costa slightly bulged at the base ; straight 

 beyond ; apex somewhat depressed, apical margin very oblique, scarcely convex ; 

 grayish-brown, dusted throughout with whitish scales ; a consi^icuous pale-yellow 

 crescent-shaped blotch at the commencement of the dorsal cilia ; cilia grayish- 

 brown ; neuration very peculiar ; the apical vein reaches the costal margin im- 

 mediately above the apex, and from before its middle sends to the costa a forked 

 branch. 



Hind-wings and cilia, pale grayish-brown ; veins six and seven parallel, three and 

 four from a point. 



Abdomen and legs, pale grayish-brown.

 A single specimen given me by Mons. Eagonot. 



(Ucophora pseudospretella Stn. 



It is curious that this widely distributed and far too common species should not 

 have been hitherto recorded from the United States. Zeller had four specimens from 

 Washington Territory and I have received it from Vancouver and taken it in Califor- 

 nia. It has apparently been overlooked in the Eastern States. 



I have also a unicolorous bronzy-brown species which should undoubtedly be placed 

 in this genus, but the palpi are broken, and I prefer to wait for better specimens be- 

 fore describing it. 



Psecadia zelleriella Chamb. 



I feel confident from a careful examination of Chambers's descriptions of his Hi/pon. 

 omenta zelleriella and his Hgijonomeuta texanella that these two supposed species are 

 one and the same ; both descriptions agree perfectly with specimens in my own col- 

 lection. 



The description of zelleriella, though earlier than that of texanella, is more minute 

 and complete. I have not seen the types. 



It is important in this connection to remember that Chambers has also described 

 an AnesgcMa texanella from the same locality. This is evidently a distinct species, and 

 one with which I am not acquainted. His Hyponomeuta texanella is obviously a true 

 Psecadia, but as it must be dropped in favor of the prior name, zelleriella, no confusion 

 need arise from retaining his Anesycliia texanella, which should also be placed in this 

 genus. 



Psecadia discostrigella Chamb. 



= siibccerulea Wlsm. 



When describing suhccerulea I was unacquainted with Chambers's Anesycliia dis. 

 costrigella, except by the description. A comparison of a series of both sj)ecies has 

 convinced me that the specimens from Arizona, Utah, and Colorado, which agree with 

 my figure of Chambers's type ^in the Museum of the Peabody Academj-^ of Sciences, 

 Salem, Mass.,) are merely darker forms of my Californian species, the name of which 

 nmst be suppressed as a synonym of discostrigella. 



Psecadia marmorea sp. n. 



Antennce, brownish, fuscous. 



Palpi, recurved, banded with white and brownish fuscous; second joint with a broad 

 brownish fuscous band and a spot of the same color, more strongly marked on the 

 outer than on the inner side ; apical joint with two brownish fuscous bands of 

 about equal width on both sides, having the extreme apex and a belt in the mid- 

 dle of the joint white. 



Head, whitish, with a conspicuous white spot above the juncture with the thorax; 

 face grayish.
