324 BRITISH LEPIDOPTERA. 



hinaustreten [Glitz, Stett. Ent. Zrituny, xxxiii., pp. 24-25 (1872)] . 

 Glitz himself afterwards referred his A T . dioersa to X. obliijudla, Hein., 

 and gives the latter name priority. Martini remarks that " A r . din-rxa- 

 obliquMa is an ill-defined species, and not to be separated with 

 certainty from N. salicis, Sta. The differences in the mines appear 

 to be due to the greater thickness of the leaves of Salix cinerea and 

 S. caprea" (Stett. Ent. Zeit., liv., p. 117). 



N. OBLIQUELLA (DIVERSA) AS A BRITISH SPECIES. Of this Species, 



Wood says : " N. dirersa is the one species that I take here that I 

 know next to nothing about. I bred a single specimen some years 

 ago and, if my memory serves me correctly, the mine was a wide 

 gallery with a narrow frass-track. It was not rare one season, rather 

 early in autumn, but I have been on. the look out for it since to no 

 purpose " (tn Mtt., June 3rd, 1898). 



COMPARISON OF N. OBLIQUELLA WITH ITS ALLIES. N. oblirjuella 

 agrees with the species in the preceding section (X. antpdifasciella, etc.), 

 in the fascia being quite similarly placed, and of similar form, but 

 diners in the colour of the fascia, and its want of metallic lustre. In 

 N. tityrella and its allies, the fascia is placed beyond the middle of the 

 wing, and the cilia show no divisional line. In the group containing 

 N. salicis, the anterior wings are also more coarsely scaled before the 

 fascia, which is placed more posteriorly (Heinemann). X. dlrcrxa 

 (nbliqnella) differs from X. salicis and X. myi'tillella, in having a less 

 bluish tint on the fore-wings, and in having a narrower transverse 

 band. From the former it differs also in the more regular arrange- 

 ment of the black scales along the divisional line running through the 

 cilia ; from X r . tnyrtillella in having the basal area of the fore-wings, 

 the transverse band and the cilia, more yellowish in colour (Heinemann 

 and Wocke). 



MINE. The mine is placed near the mid-rib, forming a slender 

 slightly tortuous gallery, filled with dense brown frass, and is, on that 

 account, a little striking (Sorhagen). 



COCOON. Brown (Sorhagen). 



FOOD-PLANTS. Salix alba, S. rinrinalis. Smooth-leaved willows 

 (Heinemann and Wocke). 



TIME OF APPEARANCE. Sorhagen gives it as double -brooded, the 

 larvffi to be found in July and October in the leaves of SalLr rintinalis. 

 Heinemann found imagines in May, on the edges of woods near Bruns- 

 wick. Bering gives the larva as occurring in September in Friedland. 



LOCALITY. HEREFORD: Tarrington (Wood). 



DISTRIBUTION. Denmark : Copenhagen (Bang-Haas). Germany : 

 generally distributed (Heinemann and Wocke) , Friedland, nr. Breslau 

 (Sorhagen), north-east Germany (Wocke), Alt Damm (Hering). 

 Switzerland : nr. Zurich (Frey).
