In the U. S. National Museum are several specimens labeled by 

 Lord Walsinoham, Gelechia C07idusella Walker; these are identical with 

 specimens thus named by Lord Walsingham in collections of Dr. Dietz, 

 and in the Philadelphia Academy of Natural Sciences. They agree 

 with Walker's description and evidently correcth' represent his species. 



They are the same as tj^pe no. 44:7, in the U. S. National Museum, of 

 Gdechia grissefasciella, received with his label from Chambers, thus 

 confirming the synonymy made by Walsingham. There is one other 

 supposed "type" of grissefasciella, namely, in the Museum of Com- 

 l^arative Zoology, Cambridge, but this is an entirely different thing, 

 an undescribed species of Nealyda, unhappily unfit for description; 

 it does not, however, agree with Chambers' description, while U. S. 

 National Museum type does, and the latter is evidently authentic. 



Lord Walsingham also made crescent if asciella Chambers a synonym 

 of conclusella, but this, as previously shown (p. 846), was done on 

 faulty evidence, and crescentifasciella is a distinct species belonging 

 to Anacampsis. 



The present species has veins 3 and 4 'n forewings stalked, and 

 thiM-eb}^ differs from the most of the species in the genus in which it 

 is placed. I am, however, at present not willing to differentiate it 

 ( generically. 



GELECHIA RILEYELLA Chambers. 



Dejwessaria rllei/ella Chambers, Can. Ent., IV, 1872, pp. 106, 129, 147, 148; 



Bull. U. S. Geol. Surv., IV, 1878, p. 138.— Riley, Smith's Li^^t Lep. Bor. 



Am., No. 5277, 1891. 

 Gelechia rileyella Riley, Smith's List Lep. Bor. Am., No. 5468.— Busck, Proc. 



U. S. Nat. Mus., XXIV, 1902, p. 732; Dyar's List Amer. Lep., No. 5769, 



1903. 



Type no. 402, in the U. S. National Museum, of Depressaria. riley- 

 < llii^ ])earing Chambers' handwritten label and the date 1872, is the 

 same a.'i.tiiree types found in the Museum of Comparative Zoology in 

 Cambridge, also bearing Chambers' labels. 



These types are all in very poor condition specifically, )>ut prove 

 conclusively that the species is a true Gelechia. 



The t3"pe in the National Museum bears Lord Walsingham's ])lue 

 label no. 1170, and there is also a better preserved specimen deter- 

 mined by Walsingham and bearing his blue label no. 1211.

No other specimens are known to me.
