although it does not differ from Prof. Zeller's figure (Verb. z.-b. G-es. 

 Wien, 1873, t. iv. fig. 27) in this respect.

A specimen in Prof. Fernald's collection is labelled "Nbthrin dola- 

 bella, Zell., but the form and color of the palpi distinguish it from that 

 species. 



From a careful comparison of specimens and descriptions I find the 

 best distinguishing marks between what I suppose to be Nothris dola- 

 bella, Zell., and Gelechia bilohella are the form and color of the palpi, 

 which in the former have a projecting tuft under the second joint, with 

 the extreme tip of the apical joint fuscous. In the latter no tuft on the 

 second joint, and the tip of the same color as all their upper surface, 

 quite pale ochraceous. The supposed type of Nothris eupatorie/la, 

 Chambers, received from Mr. Goodell, very obviously agrees in these 

 particulars with the latter form ; whereas Chambers's description of 

 N. eupatoriella agrees better with the former. I think therefore that 

 Mr. Groodell's specimen must be one of Chambers's series, but not the 

 actual specimen from which the description was taken, and that in this 

 series the two species must have been mixed. 



This is, moreover, a somewhat peculiar variety, differing from both the 

 species described by Zeller in having the pale ochreous ground-color of 

 the fore wings suffused with iron-grey, and with a distinct yellow ochre- 

 ous margin to the dark streak internally : the patch on the dorsal mar- 

 gin is also separated from the base. I believe it to be a variety of- G. 

 bilobella, but it may possibly prove to be a distinct but closely allied 

 species. 



Chambers's description applies correctly to what I believe to be the 

 true Trichotaphe setoseila, Clem. {Nothris dolabella, Zell.), whereas 

 Mr. Chambers's Begoe costaluteella , Can. Ent. ix. p. 2-1 (afterwards 

 printed Begoe costolutella in his " Index"), is probably Gelechia bilo- 

 bella, Zell. Both these two forms have short maxillary palpi. Should 

 they not therefore be both separated from Nothris, which, L believe, has 

 no maxillary palpi? or are we to follow Herrieh-Schiiffer and others in 

 regarding Nothris as inseparable from Gelechia?
