254 HAUSTELI.ATA. LEPIDOPTF.R A. 



Anterior wings very glossy silver, with an interrupted broad, irregular, shining 

 coppery-gold streak, composed, as it were, of an oblique band near the base, 

 detached from the other portion by an extremely brilliant silvery line, then 

 a second very broad transverse streak extendhig from the costa to the inner 

 margin, and connected with a third, which occupies the margin portion of 

 the apex : thorax dusky. 

 My specimen of this insect occurred at Darenth in June: it is a 



very beautiful and brilliant species.

Ti. I. V-ella. Haworth — Ar. I. V-ella. Steph. Catal. ii. 205. No. 7297. 



Anterior wings silvery, obscurely tinged with yellowish on the costa, with a 

 broad straight golden fascia in the middle, becoming attenuated towards the 

 inner margin, and not touching the costa, but connected on the disc towards 

 the costa, with a second flexuous fascia extending from the costa to the inner 

 margin and apex, and resembling a Roman V : posterior wings lead-coloured, 

 with golden-brown cilia. 

 This insect is also a rare species : I have a beautiful pair of varieties 



from Haworth's cabinet, which were taken by him at Darenth wood, 



where I had previously found the insect in June. " Maldon Park."

Genus CCCXLIV. — Argyrcmyges, Curtis. 



Palpi two, very short, drooping, slightly divaricating, nearly straight, bent 

 obliquely backwards, subfiliform, and clothed uniformly with scales, the 

 terminal joint longer than the others combined, compressed, obtuse : maxilla 

 rather short. Antennw nearly as long as the wings, similar in both sexes, 

 the basal joint robust : head small, clothed with imbricated scales in front, 

 and with erect ones on the crown: eyes small: thorax moderate, not 

 crested : wings convoluted during repose ; anterior linear, sublanceolate, 

 frequently adorned with metallic colours, displayed in obliquely-placed 

 markings : cilia very long on the hinder angle and a portion of the inner 

 margin ; posterior very slender, linear, with very long cilia on both margins : 

 body rather long and slender, acuminated in the females. 



This genus comprehends some of the most beautiful of our Lepi- 

 dopterous insects ; they are in general minute, with very narrow 

 anterior wings, more or less marked with gold and silver, the latter, of 

 pale colours, being mostly disposed obliquely on both the costal and 

 inner margin, thereby forming acutely angulated marks ; the apex is 

 also frequently adorned with a slightly darkened ocellar spot ; the cilia 

 are remarkably long both at the apex of the inner margin and on each
