Mr. W. H. Patton, of Hartford, Conn., is responsible for the 
statement* that Dr. F. Karsch has shown that kuehniella and in- 
ierpundella are only dimorphic forms of one species. In 1884, 
Dr. Karsch gave it as his opinionf that Tinea zece of Fitch might 
prove to be a variety of kuehniella ; and in an article in “Insect 
Life” for November, 1890,J under the caption “Notes upon Ephes - 
tia interpunctella (Hiibn.) Zeller,” Mr. Patton gives both E. kueh¬ 
niella and T. zece as synonyms of E. interpunctella. Under the 
head of “Special Notes,” the editors of “Insect Life” (1. c. p. 134) 
strongly dissent from Mr. Patton’s conclusions, stating that they 
long since adopted zece as a synonym of interpunctella , but that 
they now fully believe in the distinctness of kuehniella , though 
inclined earlier to a different opinion. 
Mr. Geo. D. Hulst, in his monograph of the Phycitidse of North 
America,* has placed interpunctella in the genus Plodia, and left 
kuehniella under Ephestia. The main difference between the two 
genera, as indicated by Mr. Hulst, is that in Ephestia the palpi 
are erect, while in Plodia they are porrect. 
Mr. Ragonot has shown§-that Mr. A. W. Scott’s Hyphantidium 
sericarium evidently belongs to the genus Ephestia and, accord¬ 
ing to the description, closely resembles kuehniella ; and he is of 
the opinion that the former will prove identical with the latter 
species, since its larval habits are precisely the same. For the 
present, however, Mr. Ragonot is content to let the species remain 
as Ephestia sericaria (Scott). 
Mr. Hulst says (1. c., p. 199) that he has specimens from New 
Mexico which connect Ephestia fuscofaciella Ragonot with E. 
kuehniella , and he is of the opinion that the former may prove only 
a variety of the latter.
