878 PROCEEDINGS OF THE NATIONAL MUSEUM. 



Two undoubtedly authentic t^^pes of this .species labeled by Cham- 

 bers, Cirrhi plidiinella., are found in the Museum of Comparative 

 Zoology in Cambridge and prove that the genus drrha^ which can 

 hardly be said to have been characterized by Chambers' few lines of 

 general remarks, is synonymous with Gelechia. Chambers changed 

 his specilic name when he discovered the food plant, which was not 

 admissible, and the species must be known under its original specific 

 name. 



Food plant. — PlantanuH occldentalis. 



Habitat. — Kentucky . 



GELECHIA UNCTULELLA Zeller. 



Gelechia unctulella Zeller, Verh. k. k. zool.-bot. Gesell. Wien., XXIII, 1873, 

 p. 257.— Chambers, Bull. U. S. Gef)l. Surv., IV, 1878, p. 147.— Riley, 

 Smith's List Lep. Bor. Ain., No. 5503, 1891. — Bcsck, Dyar's List Amer. Lep., 

 No. 5751, 1903. 



The unique type in good condition is in Cambridge Museum. 

 Zeller mentions onlv two black dots, one on the disk and one at the 

 end of the disk, and saj's: ''Andere Zeichnungen fehlen.'' These two 

 spots are the most prominent and the only ones seen in certain lights 

 against the nearly black general color of the wing, but as a matter of 

 fact there is, as type also shows, three other smaller black spots on the 

 fold and one more on the disk. All of the spots, however, are quite 

 indistinct. 



In the U. S. National Museum is a very large ])rcd series of this 

 species from Colorado and Arizona, l)red respectively by Dr. H. G. i 

 Dyar and Mr. E. A. Schwarz from Thei'iaopHk and from Bohinia. ^ 



Dr. Dyar has pulViished his notes on the larva. ^ 



According to Mr. Schwarz, this species is at some places so abun- 

 dant as to do actual damage, spinning up ever}^ leaflet of the Robin la. 



GELECHIA OBSCUROOCELELLA Chambers. 



Gelechia ohiiniroocek'lla ('ha.mheks, Cin. Quart. Journ. 8ci., II, 1875, p. 254; Bull.] 

 U. S. Geol. Surv., IV. 1878, p. 145.— Riley, Smith's List Lep. Bor. Am., J 

 No. 5424, 1891.— BusCK, Dyar's List Amer. Lep., No. 5752, 1903. 



Type of this species is lost, and no authentic specimen is found, ])ui 

 I have with little hesitation determined from description as thi 

 species a specimen from San Antonio, Texas, collected in May, which 

 in every respect agrees with Chambers' description, and which, I 

 have no doubt, truly represents this species.
