142 HAUSTELI.ATA. — LEI'IDOPTERA. 



short, Stout in the males and pubescent within, slender and simple in the 

 females : head small, with a short tuft between the antennae : eyes small : 

 thorax rather stout, with metallic stripes, not crested: wings deflexed, 

 anterior entire, slightly rounded on the hinder margin, the costa faintly- 

 dilated on the shoulder, and in the males reflected, forming a thickened 

 edge ; the disc with metallic characters on ^ plain dark ground : posterior 

 wings rounded, not emarginate : legs rather long, slender, with a tuft at the 

 apex in both sexes, smallest in the femaleSj in which sex the body is 

 stoutish : legs short. 



The males of this genus are well characterised by having the base 

 of the costa of the anterior wings deeply reflected, and both sexes 

 have the same wings of a dark hue (generally tinted with orange or 

 tawny,) with various silvery marks thereon, resembhng letters : they 

 are also entire, rounded on the anterior margin, and not fasciated, 

 neither do they possess a circular spot at the apex, so common in this 

 family of insects. ,

Anterior wings obscure luteous or orange-brown, palest at the base ; on the 

 disc are two silvery marks resembling the letters I L, between which the 

 colour is rather dark ; cilia luteous and very glossy : posterior wings fuscous ; 

 cilia pale dull yellow. 



The wings vary considerably in tint, being sometimes dull testaceous, or of an 

 olivaceous hue, and the silvery marks are more or less distinct. 



Found, not uncommonly, at the end of June, in woody places 

 within the metropolitan district, at Darenth, Coombe wood, Sec; 

 also at Hertford, Ripley, the New Forest, Devonshire, &c. "Monks' 

 wood." — C. C. Bahington, Esq.

Or. obsoletana. Steph. Catal. ii. 182. No. 7012. 



"Wings dull black ; anterior with numerous irregularly dispersed silvery dots, 



and some of them slightly disposed in streaks ; cilia also silvery : posterior 



wings rather less obscure, with deep black cilia. 



The only example I have seen of this very distinct insect was 

 taken at Birch wood, in June.
