Insects, 



beginning of October on strawberry leaves ; it is pale amber-yellow 

 with the head brownish, and makes long, narrow, tortuous mines, with 

 a rather slender excremental line. The cocoon is rather broad and 

 flat, of a brownish yellow colour. 



Found at Frankfort-on-the- Maine by EJerr von Heyden, and last 

 year it was also noticed at Wolfenbuttel.

Capillis atris, antennarum conchula alba; alis anterioribus nitidis, 

 viridi-aureis, in margine anteriore cupreis, apice violaceo-l'uscis, 

 fascia postica late argentea, nitidissima, ciliis apice cinereis.

This species, named by Frey, who forwarded me a specimen, is very 

 like N. gratiosella, but is distinguished by the bright coppery colour 

 of the costa of the anterior wings, by the pale gray cilia and hind wings, 

 and by the whitish gray middle tibiae, and from the remaining black- 

 headed species of this group it is further distinguished in the silver 

 fascia not being bordered with dark towards the base. The frontal 

 tuft is black ; the eye-caps pure white. 1 cannot perceive a pale cer- 

 vical toft. The legs are blackish gray ; the middle tibiae are whitish 

 gray ; the middle tarsi and the tips of the posterior tarsi are white. 

 The anterior wings are narrow, of nearly uniform breadth, in colour 

 similar to N. gratiosella, but paler greenish bronze with reddish golden 

 tinge and considerable glossiness ; on the costa they are purple-violet, 

 especially before the fascia, beyond which pale brown to the base of 

 the cilia, with a faint violet tinge. The fascia is rather posteriorly 

 placed, somewhat oblique ; it is broad, silvery, with faint golden gloss 

 and highly metallic. The cilia are gray, with their tips and at the 

 anal angle more whitish. Posterior wings pale gray. Frey writes 

 me that the specimen sent was paler, and on the costa of a less brilliant 

 coppery red than his other specimens. 



According to Frey's communication the larva is green, and mines 

 circular and visceriform tracks in Ulmus campestris at Frankfort-on- 

 the-Maiue.
