NEPTICULA NYLANDRIELLA. 221 



Bucculatrix concolorella, treated as a distinct species by Staudinger and 

 Wocke (Cat., p. 334, no. 2956), but wbich he (Warren) considers 

 identical with B. cristatella, Zell. He adds that the resemblance that 

 N. nylandriella bears to very small B. cristatella is very striking, and 

 that Herrich-Schaffer's figure represents the species admirably. There 

 is not a trace of purple towards the apex, and the insects he has 

 examined are certainly not wasted. 



Imago. — Head yellowish, frontal tuft of $ brown, of $ pale, 

 ochreous. Anterior wings narrow, very smooth, extremely shiny, pale 

 silvery-grey, with a faint yellowish tinge ; apex scarcely darker, with a 

 faint violet gloss ; cilia whitish-grey, rather darker towards their base. 

 Posterior wings and cilia pale grey. 



Sexual dimorphism. — The frontal tuft of the male is brown, that 

 of the female pale ochreous-yellow. The cervical tuft of the male is 

 more whitish, that of the female pale yellow. 



Mine. — Gangmine geschlangelt (Sorhagen). 



Food-plant.— Pyrin* aucuparia (Wocke). 



Time of appearance. — The original specimens on which the species 

 was named were captured near Helsingfors, in June. Imagines were 

 captured by Griffith, on June 6th, 1885, on the trunks of mountain-ash 

 trees, in a wood on Betty Hill, in Sutherland. Sorhagen gives the 

 larvae as occurring in August- October, the imagines in May and June. 



Localities.— Lancashire : Preston (Threlfall). Sutherland : Betty Hill 

 (Griffith). 



Distribution. — Germany : Hanover, Breslau (Sorhagen), Bruns- 

 wick, on beech trunks (Heinemann). Russia : Helsingfors (Tengstrom). 

 Sweden : (Wocke). 



Group II. — Cilia of the anterior wings with no dark divisional 

 line, but cilia becoming gradually paler towards their tips. Anterior 

 wings with a pale metallic transverse fascia ; basal area smooth and 

 metallic, fascia with a more or less defined margin towards base.
