NO. 1304. REVISION OF AMERICAN GELECHIID MOTHS— EVSCK. 809 



While there ivS no difficulty about the identity of Cleniens's genus, it 

 is not quite so satisfactory Avith the s])ecitic identity of his type of the 

 genus. 



Lord Walsinghani placed it as synonymous with Zeller's (/ilvosco- 

 pella^ and as Clemens' type is not in existence it is difficult to proye or 

 disproye the identity absolutely, and I should have left it on Walsing- 

 ham's authority, eyen though the synonymy seemed very strange from 

 the quite ditferent descriptions of the two species, if I had not been 

 able to examine the evidence on which Lord Walsingham l)ased his 

 opinion in 1882. 



These specimens (labeled with Lord Walsingham's blue labels, nos. 

 148, 1-49, and 150, corresponding to his identification in his notebook^), 

 are in Professor Fernald's collection, and they surely are not the same 

 as the type of Zeller's gllvoscopeUa, preserved in excellent condition 

 in the Museum of Comparative Zoology. 



They are in rather poor condition, but agree as far as can be made 

 out with undoubted specimen of ahidiselhi Packard, a large, bred series 

 of which is in the U. S. National Museum. 



Here also are to be found two specimens lal^eled in Lord Walsing- 

 ham's handwriting apicitripimcteUa^ one determined in 1887 and one 

 in 1891. The iirst is bred from locust and is rohin'wJla Fitch (p. 812), 

 and the other is the same as the specimens in Professor Fernald's 

 collection and is ahietiseUa Packard. 



That Lord Walsingham at that time, with the limited material at 

 his command, was not very certain about these nearly related, similar 

 species is shown b}^ his suggestion^ th^t dorsiviiiella ZeWev and crista- 

 tella Chambers might also be mere varieties of apicitrijmnctella. 



Clemens's description agrees well with ahietiseUa, but can not be 

 reconciled with Zeller's description of g'dvoscopella^ the one belonging 

 to the ochreous group, the other to the fuscous. 



While, then, absolute proof about this species can not be obtained 

 because the type is lost, it seems evident to me, after careful analysis 

 of the diflerent descriptions and with large series of mostly bred speci- 

 mens of all these allied species before me, that apicitriimnctella (1) 

 can not be Zeller's gilvoscopeUa^ and (2) can not be any other species 

 than Packard's aVudhella. 



Food plant, — Ahies canadensis. 



The males have the hair pencil at base of the hind wings.
