825. Gracilaria elongella, var. ? (Wocke, Cat. 2331 1. 



Greatly as this appears to differ from the typical G. elovgella (813. 

 814), I am disposed to regard it as a form of that most variable species, 

 approaching, if not identical with. G. roscipennelta, Hub. A long series 

 of G. elongel/a, taken by me in California and Oregon, includes this 

 form and almost* every possible gradation between this and the typical 

 G. elongella. G. roscipennella , Hub., is figured in Her.-Sch'aff. Schmet. 

 v. Eur. pi. 95. fig. 732. I have never seen a European specimen agree- 

 ing with this figure, and there may possibly be evidence of its distinct- 

 ness with which I am unacquainted and which may have induced Dr. 

 Wocke to maintain the name in his Catalogue (No. 2331 j, although he 

 himself regards G. roscipennella, Treitsche. as referable to G. e/ongel/a. 



1241, 1242. Gracilaria robiniella. 



Parectopa robiniella. Clem. Proe. Ent. Soc. Phil. ii. p. 4: Tin. Nor. Am. p. 207. 

 Gracilaria robiniella, Cham., see " Index." 



Parectopa lespedezaefoliella, Clem. Proc. Ac. Nat. Sci. Phil. 1860, p. 210: Tin. 

 Nor. Am. p. 144. 



Gracilaria lespedezafoliella, Cham., see " Index." 

 Gracilaria mirabilis. F. it B. S. e. Z. xxxiv. p. 212. 



In my copy of Mr. Stainton's edition of Clemens's paper (Tin. Nor. 

 Am. p. 145 ), I find that Dr. Clemens states that his Parectopa lespe- 

 dezse/o/iel/a has "two silvery white spots" on the costa. A marginal 

 note on this page, made after an examination of the type of this species 

 at Philadelphia, reminds me that it has " three decidedly." Moreover 

 my note on comparing this with the type of P. robiniella at the same 

 time is, "scarcely to be separated. I cannot, with a strong glass, de- 

 tect the slightest difference." A figure of Gracilaria mirabilis, F. & 

 B., taken from a specimen in Mr. Stainton's collection, confirms Mr. 

 Chambers's view that this species is equal to G. robiniella, Clem, (see 

 Index). 



Mr. Stainton has kindly added a footnote to the figure, "= Parec- 

 topa le&pedezsefoliel I a . These three names have therefore been given 

 to the same species. 



Genus ORM1X. 

 1142. Or III X anglicella, 8tn. (Wocke, Cat. 2366). 



I am unable to distinguish this from the common European Oi nix 

 anglicella. It may possibly have been described under another name in 

 America, but I have not been able to recognize it.
