253 HAUSTELLATA. LEPIDOPTERA. 



sinuated dusky fascia at the base, and a second very much attenuated behind 

 and sometimes interrupted, in the middle both obscurely marked with paler 

 strigse, and the latter with a conspicuous black dot towards the costa ; posterior 

 margin of a deep-lead colour, with a brighter cloud towards the middle and a 

 waved pale striga : posterior wings ashy-lead, with a darker fimbria in which 

 is a pale striga. 



Extremely variable; one of my specimens has the anterior wings of a deep 

 fuscous, with a broad perfect fascia in the middle, which as well as the basal 

 one is bordered with whitish, of a darker hue ; the posterior margin has an 

 undulated pale striga, and a conspicuous pale-ashy spot in the middle. 



This is not the Ge. contaminata of Hufnagle, which is given as a variety of the 

 preceding insect; a point I have ascertained by a recent examination of the 

 Berlinsche Magazine, as referred to in my Catalogue; but as it is probably 

 the Xe. plumbata of Curtis's Guide, I have employed that name. 



All the examples of this singular species which I have seen were 

 taken in " Forfarshire." — C. Lycll, Esq. 



Genus CCXII. — Euthalia * miJd. 



Palpi elongate, approximating, forming a sort of beak, acute, very densely 

 clothed with long scales, the terminal joint scarcely visible; triarticulate, the 

 basal joint curved, robust ; second as long, slightly attenuated ; terminal 

 minute, conic : maxillce rather long. Antenna; simple in both sexes, slightly 

 pubescent within in the males : head small ; forehead prominent : ey<?5 small: 

 thorax slender, with a bifid crest behind : wings entire, rounded on the hinder 

 margin : anterior fasciated transversely, posterior with a central dot and some 

 transverse strigse : abdomen tufted on the back, long, and very slender in the 

 males, with a rather large anal tuft : in the females stouter and shorter, very 

 acute at the apex. Larva with 10 legs, slightly pilose, stout, without tu- 

 bercles, lineated : pupa in a folliculus among leaves. 



In the position of this genus I have reverted to the original 

 sketch of my Catalogue, from a re-examination of the family: in the 

 present genus green forms a prominent colour — whence the name 

 — and it may be readily known from all the preceding genera by 

 the greater comparative length of the palpi, which approximate 

 and project forwards in the form of a beak, the wings are more or 



Eu, bene ; ^aXX<a, vireo.
