margin, and the cilia dirty yellowish : posterior wings and cilia glossy 

 leaden-brown. 

 In some examples the central streak is very obscure. 



Not very common ; found at Coombe wood, near Dover, at Ripley, 

 and at jMonks' wood, Hunts, in June and July. 



6p. 11. ocellea. Alis anticis osseo-albis lucidis subargenteis, aloniis perpaucis 

 ochroleucis sparsis, apicibus macuLl ocellari subluteu. (Exp. Alar. 4^ lin.) 



Yp. ocellea. Steph. Catal. ii. 204. N'o. 7289. 



Anterior wings of a shining bone-white, or cream-colour, with a slight silvery 

 gloss ; the surface sparingly sprinkled with ochreous-white atoms, thickest 

 towards the apex, the latter with a varied somewhat lutcscent dot, on the 

 anterior angle, surrounded by a white circle and a lutescent exterior one, 

 the latter extending outwardly to the tip of the cilia : posterior wings 

 fuscous. 



Apparently very rare: I have a pair which I caught several years 

 since in June, at Darenth wood. 



Genus CCCXLIII. — Argyrosetia* mihi. 



Palpi slender, rather long, drooping and incurved, not bent backwards, 

 slightly divaricating, clothed with very short scales, the terminal joint nearly 

 as long as the other two, and bent, its apex acute: via.iilla; rather short. 

 Aniennw not so long as the whigs, slender, with the basal johit robust ; 

 simple in both sexes : head small, with imbricated scales in front, and a tuft 

 of porrected ones on the crown: eyes small: </torax rather slender : wings 

 convoluted; anterior sublanceolate-linear, rounded at the apex, the disc 

 with darker metallic fascise, more or less resembling letters, the hinder 

 margin with short cilia anteriorly, and very long ones posteriorly : posterior 

 wings sublanceolate-acute, with very long cilia : body rather long and 

 slender, acuminate in the females. 



The insects comprised in this beautiful genus — which nearly 

 corresponds with Argyresthia of Iliibner — differ from the fore- 

 going by the brilliant metallic hue with which their anterior wings 

 are adorned, the ground colour being generally pale silvery, 

 with various lines thereon, more or less resembling letters, some 

 extremely distinct ; they are long and sublanceolate, with short cilia 

 on the anterior angle, and very long ones on the hinder one, as in the 

 following genera ; but from them they may be known by having the 



Apyvpoij, argcntum, (rtt thiea.
