ON NORTH-AMERICAN TINEID^. 



[Feb. 15, 



examples to examine the neuration, I can find no difference in struc- 

 ture beyond the very sKght modification above referred to. 



A careful comparison of the descriptions of JEtole and Heliodines 

 shows them to be at least very closely allied, if not identical ; and as 

 Mr. Chambers's figure of the neuration of his Mtole bella ( Journ. 

 Can. Soc. Nat. Hist. Jan. 1880, p. 26, fig. 54) does not seem to 

 agree precisely with his previous description of the number and 

 position of its veins, there may, perhaps, be some doubt as to the 

 sufficiency of the evidence on which he separates them. 



^TOLB, Chambers 

 (Can. Ent. vii. p. 73). 



"Scales of the head appressed; 

 forehead wide, obtuse. 



" Antenuag sim^sle, ratlier thick, 

 about as long as the body; basal 

 joint short." 



Tongue long and naked. 



No maxiUary palpi. 



" Labial palpi very short, drooping, 

 the third joint pointed. 



" The discal gives off two branches, 

 the superior being furcate before the 

 apex, with one of the branches to 

 each margin" (figured simple, not 

 furcate).

Heliodines, Stainton 

 (Ins. Brit., Lei3. Tin. p. 243). 



" Head smooth ; forehead obtuse. 



" Antenna setaceous, almost as long 

 as the body; basal joint short, cla- 

 vate. 



" Tongue of moderate length." 



(No maxillary palpi mentioned, 

 none existing.) 



" Labial palpi small, rather thick, 

 acuminate. 



" The furcate apical vein ter- 

 minates in the apex and in the hinder 

 margin."

Heliodines rmsella. 



Neuration of wings. 



If the upper fork of the apical vein (apparently described, but 

 omitted in the figure, by Mr. Chambers) be inserted, the neuration of 

 the two genera will be found to correspond very closely, with the ex- 

 ception of the absence of a short vein in u^tole which in Heliodines 

 runs from the lower edge of the cell to the dorsal margin, which may 

 possibly have been overlooked. 



Mr. Chambers places his genus among the Elachistidse, and states 

 that it "resembles closely the European Chrysoclista linneella," which 

 is the British genus placed nearest to Heliodines by Mr. Stainton, 

 although not so placed in Wocke's Catalogue.
