194 THE CANADIAN ENTOMOLOGIST. 



however, I have seen an authentic specimen of impigritella without the 

 means of comparing it with exoptatella; and I now think it not improbable 

 that exoptatella will prove to be that species. G. ftiontisella, however, is 

 something quite different. 



After describing Heliodines extraneella, Lord Walsingham proceeds to 

 discuss the question whether the genus Aetdle Cham, is the same with 

 Heliodines. I suspected as much when I described Aetole belia, but my 

 knowledge of Heliodines was then and is now too imperfect to me to feel 

 certain about it. Lord W. gives my brief account of Aetole and Mr. 

 Stainton's still briefer account of Heliodines in Ins. Brit. v. 3, with copies 

 of Mr. Stainton's and my figures of the neuration of the genera, and 

 alludes to the discrepancy between my printed account of the neuration 

 of the fore Avings of Aetole bella and my figure. The discrepancy exists, 

 and in my original pencil sketch of the neuration I find this endorsement 

 made by me just after the figures were published : " the published figure 

 is incorrect in that it does not represent the apical vein as being fur- 

 cate," and the original figure represents it as being furcate. This being 

 supplied, the neuration of the fore wings is the same in the two species, 

 and not as Lord Walsingham thinks, simply corresponding " very closely 

 with the exception of the absence of a short vein in Aetole., which in 

 Heliodines runs from the lower edge of the cell to the dorsal margin, and 

 which may possibly have been overlooked." In other words, the apical 

 vein of my figure being made furcate, the neuration of the fore wings is 

 identical with that of Heliodines as represented in Mr. Stainton's figure. 

 But the form of the wing of Aetole is narrower and it is more distinctly 

 caudate. The hind wing in Mr. Staintoji's figure is also wider and the 

 median gives off a branch which is wanting in Aetole. These small 

 differences, however, are perhaps unimportant, and it is more than likely 

 that Aetole Cham, is the equivalent or American form of Heliodines 

 Stainton ; and this view is supported by the ornamentation. 



Lord Walsingham's descriptions are accompanied by two plates con- 

 taining twenty-eight beautiful figures of the species described, with illus- 

 trations also of the neuration of the wings and form of the head and its 

 appendages, of Phryganeopsis brunnea and Euccrotia seairella, and is a 

 most valuable addition to our knowledge of the American Tineidce. 

 Every one interested in the group owes him " a vote of thanks," and 

 hopes that he will persevere in so good a work, and not abandon it as the 

 writer of this has reluctantly been compelled to do.
