30 THE ENTOMOLOGIST. 



No. 2. — As described. 

 „ 2a. — Intermediate between 2 and 3. 



No. 3. — As described, = semidecandriella. 



No. 4. — As described above. 

 „ 4 a. — Tlie black specimen mentioned in description of 

 No. 4. 



These specimens vary in size. None are larger than 

 marmorea, but some are much smaller in each group, except 

 No. 4, the specimens of which are very uniform in size. 



No. 1 seems to agree fairly well with junctella, Stainton's 

 Man. vol. ii. p. 339, although I sliould hardly say my specimens 

 had a " reddish brown " blotch. Do any of my forms agree with 

 the original description of knaggsiella ? I cannot find anything 

 about this insect, and cannot help feeling that if Mr. Coverdale 

 is right in his naming of No. 1 a, that, at any rate, the Gelechia 

 junctella of the ' Manual,' knaggsiella and semidecandriella will all 

 tarn out forms of one exceedingly variable species. At present 

 I am rather in the dark ; and if any of our older entomologists 

 could give me a correctly-named British or continental type of 

 either junctella, knaggsiella, leucomelanella, or vicinella for 

 reference, I should be exceedingly obliged. One thing seems 

 certain, — if No. 1 (junctella). No. la [knaggsiella), and No. 3 

 [semidecandriella) are distinct species, then I have at least seven 

 distinct species in my series, for there is quite as much difference 

 in the other groups as in these. 



I should not be surprised if No. 4 was a novelty, I have no 

 direct connecting links between Nos. 3 and 4 ; it is constant in 

 size ; but the taking it at same time with the other forms, and its 

 general appearance, have led me to the belief (perhaps erroneous) 

 that they are all one species. That Nos. 1, 1 a, 2, 2 a, and 3 are 

 either one species or else five distinct ones, I firmly believe, 

 because only the smallest points of difference can be detected, 

 such as ground colour, partial obliteration of a line, &c. ; and if 

 the differences between any two of the forms is sufficient for 

 specific rank, so are the differences between the others. I see in 

 Staudinger and Wocke's Catalogue, "No. 1961, j^ulla, Tgstr. 

 Bidr. 126." Would the description of this agree with my No. 4 ? 

 which would form a very good coiniecting link between maculi- 

 ferella and junctella, the place assigned it in the list. I see, too, 

 in this list, that between knaggsiella and maculiferella, &c., are
