16 Mr. J. W. Douglas on the 



Sp. 46. Mthiops. 



An. Mthiops, Westw. 

 Expansion of wings, 8 — 9 lines. 



Head, antennae, palpi and thorax jet black. Anterior wings 

 long, narrow and pointed, also jet black, with 4 — 5 raised scales 

 of the same colour. Posterior wings fuscous, lighter at the 

 base. 



Found in the neighbourhood of Manchester, I believe on 

 poplars. 



Sp. 47. Tenebrella. 



G. tenebrella, Z. 

 CEcoph. tenebrella, Tr. 

 Ti. tenebrella, H. 434? 

 *G. unicolorella, Z. (olim.) 

 G. metallella, Sta. (Cat.) 

 Glyph, subcuprella, St.? 



Expansion of wings, b\ — 6 lines. Head, antennae, palpi and 

 anterior wings all shining dark bronze colour. Posterior wings 

 fuscous. 



This species is most probably Hiibner's tenebrella, 434, but the 

 figure is so coarse that it cannot be referred to with certainty. 

 The G. unicolorella of Zeller is the variety wanting the purplish 

 tint which the typical insect has. Mr. Stephen's description of 

 Glyph, subcuprella, like Hiibner's figure above referred to, cannot 

 be quoted, neither being sufficiently precise to distinguish the 

 species from others like it. 



Not rare in June in many places. 



Sp. 48. Tenebrosella. 



G. tenebrosella (F. v. R.), Z. 



Expansion of wings, 5 lines. 



Head, palpi and thorax shining bronze colour. Antennae 

 bronzy, with the tips distinctly white. Anterior wings shining 

 bronze. Posterior wings fuscous. 



This species most closely resembles tenebrella, but may at once 

 be distinguished by the white apices of the antennae. 



Found in June and July, but rarer than tenebrella.
