NATURAL HISTORY. Ixvii 



following species, they are chiefly found upon the Oxi/tropis Campestris and O. Arctica, 

 two papilionaceous plants ; they were captured from the 14th of July to the 13th of 

 August, 1830, and on the 19th were in a very wasted state ; on the 14th of July, of the 

 following year, one Colias only was taken." 



Gen. 770.— HIPPARCHIA. {Fab.) 



12. Rossii. Brownish-black, antennae ochreous, superior wings with two rufous 

 spots, with a black centre; having a white pupil also on the underside. 

 Expansion of wings two inches. 

 PI. A, fig. 7, underside of male. 



Male blackish ; palpi rather long and very hairy ; antennae slender and ochreous, the 

 club elongated ; wings rounded, blackish-brown, with a slight bloom of violet, 

 superior with two red spots towards the apex, with a black pupil, the superior one the 

 smaller, cilia dull ochre, indistinctly spotted with brown ; underside with the disc of the 

 superior wings chestnut colour, and two red spots towards the apex, each having a 

 white pupil and black ocellus ; inferior freckled and variegated with ochre, forming 

 several spots towards the base, and an indistinct band beyond the centre, on the 

 external edge of which are four ochreous dots ; inside of four posterior legs pale 

 ochreous. 



Female blackish, with an ochreous shade, the rufous spots towards the apex paler, 

 with the black pupil more or less distinct, and one or two smaller rufous spots between 

 them and the posterior angle ; the antennae are dotted with black on the upper side, 

 and the club is dark above and very much compressed; underside with the superior 

 wings more rust-coloured, and the two spots ochreous ; the spots and fascia on the 

 inferior wings more distinct, the margins of the latter, especially the hinder one, 

 dentated. 



This very distinct Papilio, I have the pleasure of dedicating to my friend Com- 

 mander James Clark Ross, F. R. S., &c., whose zeal for natural history is equalled 

 only by that enterprise and energy which have characterized all his undertakings, and 

 carried him so successfully through his various voyages to the Arctic Regions. 



Five specimens only were brought home, " they were scarce, and frequented the pre- 

 cipitous faces of dark-coloured rocks and loose stones. I never found," says Com- 

 mander Ross, " any of them on flowers of any kind. A few- specimens were obtained 

 on the 18th and 25th of July, 1830, and one on the 14th of the same month the year 

 following."
