2. N. .ENEELLA. 



Capillis ochraceis, penicillis et antennarum conchula flavida ; alis 

 anterioribus parum nitidis, olivaceo-aeneis, apice obscurioribus 

 parum violaceo tinctis. Exp. al. 2j — 2f Jin. 



PPygmaeella, H.S., v. 348, 1090 (Corresp. Blatt. p. 53). 



So like N. ruficapitella that it is hardly possible to distinguish them. 

 The only difference which I can find out is that the anterior wings in 

 N. aeneella are somewhat smoother and more shining, and have a per- 

 ceptibly fainter bluish violet tinge than N. ruficapitella, since only the 

 extreme tip and the base have a slight violet gloss ; whereas in N. 

 ruficapitella there are more or less numerous violet scales on the 

 entire disk, and the tip is much brighter blue or violet. His also very 

 near to N. Aucupariae, but the latter has the anterior wings paler and 

 more shining and more finely scaled, the frontal tuft pale ochreous- 

 yellow, the cervical tuft and eye-caps whiter, and the antennae shorter. 

 N. anomalella and N. desperatella are likewise more finely scaled and 

 more glossy, and have shorter antennae ; the former has, besides, a 

 brighter violet at the apex of the wing, blackish gray instead of 

 brown-gray posterior wings, and dark middle tibiae ; the latter spe- 

 cies has the anterior wings more of a coppery olive-brown. 



The frontal tuft rusty yellow, the cervical tuft and eye-caps yel- 

 lowish white, the abdomen black-gray, beneath white-gray, with pale 

 yellow anal tuft in the male. The middle legs are whitish, with only 

 a faint gray tint on the tibiae ; the hind legs gray, with the tibiae and 

 tarsi whitish beneath. The anterior wings are more coarsely scaled, 

 olivaceous-bronze, with somewhat of a golden gloss ; a faint violet 

 tint at the base ; the tip for a slight extent brownish purple or violet; 

 beyond it the cilia are dark gray. The posterior wings are pale 

 brownish gray, with the cilia rather darker. 



The larva and mine resemble very closely those of N. oxyacanthella. 

 A year ago I had collected together the mines of N. oxyacanthella on 

 whitethorn and apple, and obtained several specimens of N. aeneella, 

 which I took for N. oxyacanthella, and sent away under this name. 

 Last autumn I separated the whitethorn-mines from the apple-mines, 

 and obtained from the former N. oxyacanthella, from the latter N. 

 aeneella, and the last named certainly from mines both on wild and 

 cultivated apple trees. 



I suspect that Herrich-Schaeffer's N. pygmaeella belongs here ; it is 

 certainly not Stainton's species, since that has pale ashy gray anterior 

 wings.
