trlclie hllohella Zeller, and Ypxoloplinn {Notkrls) enpntorieUa Cham- 

 bers = N'othris dolahella Zeller has very naturally caused some troul)le. 



A larg-e series of both species is l)efore me. The Yj^so/np/ius species 

 I have bred from Eu/jaton'um in Washington City, and there can he no i 

 doubt but that it represents eupatoriella Chambers, nor that this is j 

 synonymous with Zeller's d(d<(hell<i., as thought by Lord Walsingham; \ 

 but 1 can not agree with his Lordship in placing setofiella Clemens as 

 synon3auous with this species. I 



Clemens was well acquainted with the genus J'j}soio/)hus, and would [ 

 undoubtedly have placed his species in that genus had it belonged 

 there. His description fits the Trlclwtaplie species better than the ' 

 other species, and even if there was a doubt it seems reasonable to | 

 give Dr. Clemens the benefit thereof, and not remove his species from | 

 the genus which he himself had erected and surely should be supposed j 

 to know. ' 



Lord Walsingham was led to his conclusions through a specimen j 

 labeled setosella in C. T. Robinson's collection, but it seems nmch ; 

 more natural to suppose that this specimen was wrongly labeled — j 

 taking in consideration the great similarity of the two species — than 

 to suppose that Dr. Clemens should not have known an Yjp^olophm \ 

 when he saw one, but should have described it wrongly under j 

 another — and his own — genus. i 



Clemens' type is no longer in existence, so absolute proof can not j 

 b(^ obtained; but the circumstantial evidence speaks for Zeller's view, I 

 that setosella is a Triclioto.phe \Malac1iotriche\ as originally described 

 by Clemens. ! 



Habitat. — District of Columbia, Ohio (Zeller), Kentucky (Cham- : 

 bers), Pennsylvania (Clemens). In the U. S. National Museum are ,

TRICHOTAPHE INVERSELLA Zeller. '

Epicorthylis inversella Zellek, Verb. k. k. zool.-bot. Gesell. Wieii, XXIII, 1873, :; 

 p. 248, pi. Ill, fig. 13, a, b.— Chambers, Bull. U. S. Geol. Surv., IV, 1878, i 

 p. 140; Can. Ent., X, 1878, p. 54; Journ. Cinn. Soc. Nat. Hist., II, 1880, • 

 pp. 198, 202, fig. 13.— Riley, Smith's List Lep. Bor. Am., No. 5559, 1891. 

 Trichotaphe inversella Busck, Dyar's List Amer. Lep., No. 5665, 1902. 

 1 have examined specimens determined by Chambers in the U. Si 

 National Museum and in Professor Fernald's collection; also sever4^ll 

 other specimens in the National Museum, and m Dr. Dietz's collection, 

 all agreeing with Zeller's type in the Museum of Comparative Zoology, 

 in Cambridge, and with his description and figure. 



The difference in labial palpi is only a difl'erence in degree, not in 

 kind, and the species can well l)e included in Trichota])he on that j 

 account. 



Zeller writes that veins 7 and 8 in forewing "die Fliigelspitzc 

 umfasst; " but the apex in this species, as in most of the species ))eIong
