insects. 



are rather large silvery white ; the antennae rather short ; the middle 

 legs pale. The anterior wings are deep black, not quite so coarsely 

 scaled as in N. Agrimoniella ; the fascia is silvery white, with con- 

 siderable metallic lustre ; it is angulated on the fold, but often the 

 costal portion is abbreviated, and thus it is split into two small 

 oblique spots, one of which is on the middle of the costa, the other a 

 little beyond the middle of the inner margin. The cilial line 'also 

 runs in a curve round the apex of the wing, but is rather more 

 oblique above the anal angle ; before it the cilia are blackish gray, 

 with dark tips to the scales (not, however, forming a second divisional 

 line) ; beyond it they are shining whitish. 



From N. angulifasciella and N. Rubivora this is distinguished by 

 the rusty yellow frontal tuft ; from N. arcuatella the purer white tips 

 of the cilia and the distinct cilial line, as also the darker hinder tarsi, 

 serve to distinguish it. 



Here, it appears to me, should be referred the red-headed specimen 

 of Frey's N. argyrostigma, whilst I would refer the two specimens with 

 black-brown frontal tuft to N. Rubivora. 



The larva is double-brooded, occurring in the leaves of wild apple 

 trees and whitethorn, in shady parts of woods; it forms a blotch- 

 like expanded mine, very similar to those of N. gratiosella and 

 N. regiella. It is yellow, with the head and spot on the second, 

 segment blackish.

27. N. ANGULIFASCIELLA, Stt. 



Capillis luteis, antennarum conchula albida; alis anterioribus 

 angustioribus, grossiuscule squamatis, nigris, fascia media sub- 

 obliqua, in plica fracta, interdum interrupta argentea, nitida, 

 ciliis post lineam nigram albidis; tarsis posticis nigris, apice 

 pallidis. Exp. al. 2 — 2j lin.

The anterior wings are narrower than in the preceding species, and 

 not so extraordinarily dilated posteriorly ; the colour is pure black, 

 with a faint bluish gray tinge, especially towards the apex ; the 

 fascia is silvery, very glossy, sometimes with a slight golden gloss; it 

 runs rather obliquely to the fold, where it is angulated, sometimes 

 rather indistinctly. I never saw it divided into two opposite spots,
