the latter, the correct N. aeneofasciella, since his description was 

 made from a pale captured specimen. The larva lives in October in 

 the leaves of Agrimonia Eupatoria, and makes strongly contorted mines 

 with slender excremental tracks, which can hardly be distinguished 

 from the mines of N. Agrimoniella, but it changes to pupa outside the 

 mine in an almost circular yellowish brown cocoon. 



Near Frankfort-on-the-Maine, Zurich and Wolfenbuttel. 



11. N. FRAG ARI ELLA, Heyd. 



Capillis fuscis, antennarum conchula argentea ; alis anterioribus 

 basi late viridi-aeneis, ante et post fasciam latam dilute auream 

 purpureo-fuscis, ciliis fuscis, apice griseis. Exp. al. 2 — 2J lin. 



Von Hey den in lilt. 



Frontal tuft brown, blackish in the middle, passing into gray at the 

 sides and in front; the eye-caps small, rather larger in the male, 

 greenish white with metallic gloss ; the antennae are in both sexes 

 more than half the length of the anterior wings, blackish ; the palpi 

 white. I do not perceive that the cervical tuft is pale. The entire 

 body is shining greenish bronze, likewise the legs, only they are darker; 

 the anus of the male has two small pale gray tufts. The anterior wings 

 are narrow and elongate, of nearly uniform width, very shining greenish 

 brassy to beyond the first third of the wing ; the remainder to the apex 

 is of a rather pale brown, inclining somewhat to purple or violet-brown, 

 more rarely to violet-blue, which before the metallic fascia appears as 

 an equally broad fascia, distinct towards the base, though not sharply 

 bordered. The metallic fascia is vertical at two-thirds of the length 

 of the wing ; it is rather broad, pale golden and very shining. The 

 cilia have, at their bases, brown, somewhat violet scales, but these are 

 not sharply defined ; at their tips they are pale gray, and this is also 

 the colour of the posterior wings and their cilia. Beneath all the wings 

 are pale fuscous. 



This species has perhaps some resemblance with N. splendidissima, 

 but can easily be distinguished from it. The latter has the frontal tuft 

 deep black, the eye-caps larger, and the colour of the broader anterior 

 wings beyond the brassy basal portion is quite different, golden brown 

 with a strong violet tint, often almost entirely deep violet-blue, and 

 not distinctly margined towards the pale base, but shading gradually 

 into it ; besides the metallic fascia is nearer the base on the costa and 

 perceptibly oblique. 



The larva feeds in July, and again at the end of September and
