August; also found in other parts of the metropolitan district, as 

 well as in the New Forest, Devonshire, Sec. frequenting woody 

 places. 



Sp. 3. Persicellus. Alis anticis emarginatis scahriusculis pallide sulphureis, 

 strigis abbreviatis ohscurioribus. (Exp. Alar. 9§ lin.) 



Ti. Persicella. Wien. Verz. — Yp. Persicellus. Steph. Catal. ii. 222. Xo. 7511. 



Anterior wings pale sulphur, with two obscure abbreviated oblique streaks on 

 the inner margin; the apex emarginated : posterior wings cinereous; cilia 

 white : head and thorax yellow. 



Caterpillar feeds on fruit trees : the imago appears in July. 



Rare : found occasionally in the New Forest in June. 



Genus CCCLXXIII. — Ch.etochills mihi. 



Palpi four; maxillary minute ; labial rather long, parallel, curved upwards, 

 clothed at the base with very long porrected scales, which are directed 

 forwards in form of a beak, having the terminal joint exposed as a seta in 

 the middle of the upper edge ; it is very long and slender : maxilloE moderate. 

 AntennoE during repose recurved, rather long and slender, simple in both 

 sexes : head with a tufl of elevated scales in front : eyes largish, subglobose : 

 thorax not crested : uings incumbent during repose ; anterior very long, 

 narrow, lanceolate, generally of shining colours, tinted with red, brown, or 

 ochreous, and varied or streaked with darker lines ; posterior sublanceolate ; 

 cilia rather long : body moderate, rather slender, with a tuft at the apex in 

 the m£des, slightly carinated down the back in the females : legs rather 

 short. 



The palpi of this genus differ from those of the one preceding by 

 being curved upwards, or in having the terminal joint more slender; 

 but the principal distinction consists in the form of the anterior wings, 

 which in the present genus are long, narrow, lanceolate, being 

 rounded on the hinder margin, with longish cilia at the anal angle ; 

 the disc is glossy, and is extremely variable in colour, though one 

 general and peculiar texture is found throughout , the colours arc 

 mostly red, brown, ochreous, or white, sometimes shghtly varied, with 

 a faintly raised spot towards the apex, the disc being frequently 

 streaked longitudinally, and sometimes transversely ; the posterior 

 wings are rather small, and scarcely emarginate, on their hinder 

 margin, and the cilia are longish : the insects occur chiefly in the 

 autumn.
