10 THE CANADIAN ENTOMOLOGIST. 



ostryceella, for no mine similar to that of the latter is found in this vicinity. 

 The male is nearer in ornamentation to the female ostryceella than to the 

 male, being darker, more purplish and lacking the fasciae. There are 

 slight differences in neuration between the two species, but not greater 

 than are found between different species of Lavema, or even Elachista, 

 which is perhaps nearer to these species than Lavema. . But the different 

 phraseology used in the diagnosis of the two genera may perhaps indicate 

 greater differences of neuration than actually exist ; though " discal cell 

 long, narrow and closed by an oblique discal vein," which " sends a vein 

 to the hinder margin from a point near the median vein," which (the 

 median) "passes straight to the hind margin," sending "just before the 

 discal vein a branch to the hind margin," ( Chrysopeleia) is pretty much 

 the same as discal cell narrow and rather acutely closed ; and " the 

 median divides into three branches from the apical part of the cell " — 

 (Aicea ) the difference being that the oblique vein which closes the cell is 

 in the one case considered as the discal vein, and in the other as the end 

 of the median. In both species the head is not only short and depressed, 

 but is almost acutely angled in front. The position and number of the 

 tufts is nearly the same in both species, and is not very accurately indi- 

 cated by the position of the dots at p. 73, v. 4. The two opposite costal 

 dots should be nearer together, and in ostryceella the inner one is a little 

 in advance of the outer one ; while in purpuriella the first and last are a 

 little further from the two central ones than in ostryceella. Ostryaella 

 also has two or three minute tufts in the apical part of the wing, which 

 are wanting in the other species. In purpuriella there is, loc. cit., said to 

 be an " indistinct confused yellowish fascia about the apical fourth," but 

 in some specimens this is simply represented by a pale ochreous dot 

 before the dorsal ciliae. Both species should be referred to sEcea.
