234 BRiTiSH LEtiDOPTERA. 



(1) The basal area of fore-wings greenish-brassy in N. fragariella, deep golden- 

 brown in N. gei. 



(2) The colour of the metallic band slightly golden in N. fragariella, silvery 

 in N. gei. 



(3) Head hairs in A T . fragariella, <$ dark, ? reddish ; in N. gei sometimes 

 blackish, sometimes red. 



(4) The colour of the cocoon of N. fragariella light red, of N. gei dirty- 

 greenish or yellowish-grey. 



(5) The gallery of the mine whitish, with sharply denned, continuous frass- 

 line, and wide margins in N. fragariella ; the gallery not so pale, the frass more 

 scattered, the mines with less defined margins in the mine of N. gei. 



(6) The imago of N. gei is larger, the largest examples measuring 6 mm. ; the 

 largest N. fragariella, 5 mm. 



In spite of these differences, Eppelsheim was unable to satisfy 

 himself that they were absolutely fixed, except in the matter of the 

 cocoons and the greater average size of N. gei, and he was, therefore, 

 inclined to agree with Wocke's conclusions, and unite them as the 

 same species. He, however, stated that he considered the Geiun 

 feeder should retain its name, and later (Stett. Ent. Zeit., lii., p. 351) 

 he described a new aberration as N. gei ab. semicolorella. Durrant says 

 that " English N. fragariella (from Sang) appear to have the white cilia 

 more developed [i.e., carried round to the costal cilia), while the colour 

 seems to stop short before (or about) the apex in Continental N. gei. 

 English N. fragariella are smaller than Continental N. gei." 



We do not think the last has yet been written of this puzzling 

 group, and hence keep the species separate, only noting here that 

 Wocke and Eppelsheim write — gei, Wk. = fragariella, Hein., and that 

 Wood writes — gei, Wk. = fragariella , Hein. = aurella, Fab. 



kepticula fragariella, Heinemanii.

* There is some difficulty in settling which is the original description of this 

 species. Heyden published a description in the Stettin. Ent. Zeitung, 1862, 

 p. 365, in the part elated July — Sept., hence probably not actually published until 

 October, 1862. Heinemann, in the Wien. Monats., August, 1862, p. 263, calls it 

 fragariella, Heyd., but distinctly cites it as " Heyden in litt." There is, we think, 

 no doubt that Heinemann's was the first description published. We, however, give 

 both descriptions.
