74 THE CANADIAN ENTOMOLOaiST. 



greater dififerences, for instance, exist between the palpi of L. langiella and 

 L. laetiella than are found between the latter and magiiatclla Zell. 3rd — 

 The neuration of the wings places the species among Elachistidcp. and not 

 in Lyonetidce. The neuration of the fore wings is exactly that of Lavertia 

 Stainioni, as figured Ins. Brit., v. j, except that in this species the apical 

 branch of the median vein goes to the apex instead of to the dorsal margin 

 before it. As in Lavenia, the submedian is furcate at the base, which is 

 not the case with Phyllocnistis ; and though, owing to the peculiar orna- 

 mentation of the apex, the fore wings appear to be decidedly caudate, yet 

 when denuded, they are found to be scarcely more so than in Lavenia 

 atra as figured loc. cit. The form of the hind wings is very nearly that 

 of L. epilobiella, figured loc. cit. ; and the neuration is identical with it 

 except that the superior branch of the subcostal goes to the apex instead 

 of to the costal margin just before it, and the cell is indistinctly closed. 

 The fold and the dorsal vein are both distinct. In all these particulars it 

 differs greatly from Phyllocnistis and agrees with several well recognized 

 species of Laverna as well as, if not better, than they do with each other. 

 4th — The larval habits, as described by Miss Murtfeldt, Can. Ent., 7, 

 p. 31, are those of several species of Laverna, but of no known species 

 of Phyllocnistis, aud the larva, while not closely resembling any Laverna 

 larva known to me, is still more unlike that of Phyllocnistis, in fact, totally 

 distinct from it, having sixteen feet. For these reasons I think its affinities 

 are with Laverna and not with Phyllocnistis. The specific name niagnatella 

 Zell. has priority over cenothermella. Magnatella is very appropriate if the 

 species belongs in Phyllocnistis, but not if it is a Laverna. I have never 

 seen Z. eloisella Clem., but I suspect that it will be found congeneric with 

 this species. 



I find that in the description of the species I have inadvertently omitted 

 to mention the large tuft of raised scales margined behind with brown, and 

 the short, longitudinal, black line behind it, situated within the margin at 

 the base of the dorsal cilia^, between the " two streaks which diverge from 

 the small tuft within the dorsal margin before the cilise." See v, 7, p. 31.
