278 HAUSTF.LL.ATA. LEFIDOFTERA. 



purplish-brown on the hinder margin, in certain directions of light : pos- 

 terior wings dusky-black ; cilia all fuscous : head fulvous. 



Very rare : found in the vicinity of the metropolis in June : I have 

 once or twice found it at Hertford on the heath.

Ti. fuscoviridella. Haworth. — N. G. fuscoviridella. Steph. Caial. ii. 210. 

 No. 7368. 



Anterior wings shining brownish or golden-greenish, sometimes fuscescent, 

 totally without spots or markings, cilia ashy-brown ; posterior wings nearly 

 the same, but rather paler, and less glossy, cilia pale brown : head glossy 

 greenish-brown. 



Rather an abundant species on commons and heaths within the 

 metropolitan district ; in plenty on Ockham-heath, near Ripley, in 

 Jime and July. 



Genus CCCL. — Hakfagus mihi. 



Palpi considerably longer than the head^ and greatly incurved, the basal joints 

 clothed with rather long scales, the apical one with very short ones, the 

 latter joint slender, longer than the preceding, and gradually tapering to the 

 apex, which is very acute : maxillcs short. AntenncB rather short and stoutish^, 

 faintly serrated towards the apex : head small, glossy, clothed with imbri- 

 cated scales in front : eyes small : thorax slender, not crested : vrings slightly 

 depressed during repose; anterior elongate sublinear, truncate on the hinder 

 margin, the disc black, with a central or subcentral transverse pale fascia; 

 cilia short; posterior wings elongate-ovate, with rather long cilia: body 

 short, stoutish, especially in the females : legs short, intermediate tibiae 

 incrassated. 



Without attending to the minute characters of structure in the 

 insects of this genus, they may be recognised with facility by having 

 the anterior wings deep black, with a single transverse white fascia ; 

 the anterior wings themselves are rather long, broader than in the 

 allied genera, a little rounded behind, and have short cilia ; the 

 palpi are very long and recurved, slender at the apex, the terminal 

 joint being longer than the preceding : — the species frequent willows 

 and poplars.
