12 HAUSTELLATA. LEPIDOPTERA. 



The caterpillar and chrysalis of this species hitherto remain un- 

 known -. the male, from which the accompanying figure was taken, 

 was captured in company with several other specimens by H. Sims, 

 Esq. in September 1811, either in the county of Norfolk or near 

 Epping in Essex : the female I obtained from some other, but un- 

 known, source : there are specimens of this species in the collection 

 at the British Museum, and in that of Mr. Haworth. 



I believe the first notice of this insect as a species occurs in 

 Bergstraesser's Nomenclature, where a figure is given ; and subse- 

 quent continental lepidopterists have unhesitatingly described it as 

 a distinct species from Co. Edusa, its nearest congener in Britain ; 

 and it is from a firm conviction of the accuracy of their views that I 

 have followed their steps, and introduced a figure and description 

 of it for the first time in an English dress : — but as I am fully aware 

 of the laudable caution with which many entomologists of this 

 country acknowledge the specific distinctions of insects which they 

 have not had an opportunity of examining, I anticipate a difference 

 of opinion upon this point.

The male of this elegant insect has the anterior wings above deep bright fulvous- 

 orange, with a broad black internally- waved band on their outer edge, and a 

 large round deep black spot in the middle ; beneath the disc is pale fulvous, 

 with a black, inoceUated dot, and the tip greenish : the posterior wings are ful- 

 vous above, with a narrow black border on the outer edge, a greenish tinge 

 on the inner^ and a deep fvdvescent but obsolete spot in the middle : beneath, 

 they are greenish with a suboceUated silver spot in the middle, accompanied 

 by a smaller one, both with a rust-coloured iris. The female differs in having 

 a series of irregular yeUow spots in the black margin of the anterior wings, 

 and by having the border on the posterior wings very obsoletely defined in- 

 ternally. Both sexes have a row of spots parallel with the edge of the hinder 

 margins of both wings, of which three or four of those on the anterior wings 

 are deep black, and the rest ferruginous : the cilia are yellow above, inter- 

 rupted with red-brown, and rose-coloured beneath : the body is yellowish- 

 green, with the back dusky : the antennae reddish, with the tip of the club 

 reddish-yeUow. 



This insect varies much in the intensity of the colour of the marginal band : in
