8360 Insects. 



All the three species have the anterior wings more or less shining, and 

 an indistinctly margined perpendicular metallic fascia beyond the 

 middle. 



8. N. LATIFASCIELLA, H.-S. 



Capillis atris, antennarum conchula alba; alis anterioribus dilute 

 aureo-brunneis, nitidis, apice purpureis, fascia post medium lata, 

 sed obsoleta dilute aurea ; ciliis apice griseis. Exp. al. If lin. 



Herrich-Schaffer, v. 352 (under N. gratiosella), fig. 832. 



Very near to N, regiella, but distinguished by the black frontal 

 tuft, the white cervical tuft, the rather paler, not violet-tinged, ground 

 colour of the anterior wings, with the apex purple instead of violet or 

 blue, and by the posterior wings being rather brown-gray than blackish 

 gray. It also comes very near to N. aceris, but this latter has darker 

 bronze-coloured anterior wings, and the fascia more whitish, only in 

 certain directions with something of golden gloss, and less shining. 

 In N. seneofasciella the fascia is bluish bronze-coloured. 



The frontal tuft is coal-black; the antennae short; the eye-caps, 

 which are not very large, are white; the legs gray; the posterior tibiae 

 and tarsi whitish. The anterior wings are rather narrower than in N. 

 regiella ; up to the fascia their colour is pale golden brown or golden 

 bronze, without the violet tinge of the former species; beyond the fascia 

 they are violet-purple ; the fascia is placed more posteriorly, is scarcely so 

 broad, and appears rather attenuated towards the costa and inner margin ; 

 its colour is pale golden and very glossy. The disk of the anterior wings 

 is certainly finely scaled, but not so smooth as in N. gratiosella. The 

 cilia, as also the posterior wings and their cilia, are fuscous. 



On the trunks of beech trees, at the beginning of May, near Bruns- 

 wick. 



Herrich-SchaerTer refers N. latifasciella as a probable variety to N. 

 gratiosella. His N. gratiosella is identical with that of Stainton. Of 

 the different forms which Fischer-von-Roslerstamm (Linn. Ent. iii. 

 811, 59) introduces under this species I consider the first to be N. 

 latifasciella, since the colour of the anterior wings and their cilia 

 agrees with the latter. The specimens which Zeller received from 

 Fischer are also smaller than the Metznerian specimen mentioned in 

 Anm. i. 307, which probably belongs to N. gratiosella, Sit. ; N. 

 gratiosella, F.-v.-R., would thus be the oldest name for N. Latifasciella, 

 but I hesitate again to adopt it, since Fischer had included under this 

 name a whole crowd of different species. N. gratiosella, Stt. and H.-S., 

 is larger than N. latifasciella (2j lin.) ; the frontal tuft is deep black;
