Zeller omitted to mention in lii.s description of v/olaceofusca the 

 ocellate spot at the end of the cell, which, though very indi.stinct in 

 some lights, is plainly found in his unique well-preserved type in the 

 Cambridge Museum. This type is a male and the spot is not nearly so 

 prominent in this sex as in the females. 



It is clearly the same species as represented by Cham])ers' four t.ypes 

 of discoocellella also found in the Cambridge Museum and answering 

 to his description of that species. 



Chambers' name has precedence. 



The ocellate spot at the end of the cell, as well as the lighter streak 

 below the fold, are, as Chambers observed, somewhat variable, and ; 

 especially in the males, indistinct; but the glossy violet sheen and the , 

 abruptly cut forewings makes this species easily recognized. 



In the U. S. National Museum and in the collections of Professor j 

 Fernald and Dr. Dietz are .specimens determined })y Lord Walsingham \ 

 as Gelechia {Trichotaphe) discoocellella. The species has, it is true, 

 some general resemblance to the genus TrichotapJu., but palpi and vena- 

 tion place it in Gelechia. 



Mr. Coquillet has given its food plant as Polygonum. This agrees 

 with a note from Miss Murtfeld that she reared the types from smart- 

 iceed., Polygonuiii hydvo2)i2)eroide)i.f not, as Chambers wrote, ^ "'small 

 weed." 



This species has a noteworthy color resemblance with another pol}^- 

 gonum-feeding Tineid, AriHtotelia ahsconditella Walker (p. 801). 



It has a wide distribution; Chambers recorded it from Kentucky 

 and Texas; Zeller from Texas; Coquillet from Illinois; in U. S. National 

 Museum are specimens from Kansas (Crevecoeur), Illinois (Barnes), 

 Pennsylvania (Dietz), District of Columbia (Busck).
