$ . Dull-brotvn, with a more or less intense changing 

 pink-violet lustre : a brown line along hind-marginal edge. 

 Fore-icing : covering bases of median nervures an ill-defined 

 dusky patch, Hind-iving : hind-marginal line edged with 

 white on both sides (except near apex) ; touching it 

 internally, between second median nervule and anal angle, 

 three black spots, of which the first is inwardly edged by an 

 orange, the second by a whitish, lunule, — and the third, on 

 lobe of angle, small, broadly orange, with an inward white 

 lunule; tails black, white-edged and tipped. Cilia greyish, 

 p?ler in hind-wing. Under-side. — Whitish- grey, toith 

 glistening ivhite-edged orange-ochreous transverse stria;: 

 common to both wings, a well-marked stria beyond middle, 

 in hind-wing interrupted, and acutely angulated beyond third 

 median nervule, — a submarginal, sublunulate thin stria, also 

 angulated in hind-wing, — and a hind-marginal edging line ; 

 in each wing a double striola closing cell. Hind-wing : a 

 conspicuous spot, coloured like striae, near base, between 

 costal and subcostal nervures ; orange lunules of first and 

 third spots near anal angle more conspicuous, the third marked 

 with bluish or greenish-silvery scales, a patch of which also 

 marks the interval between these two spots. 



? . Broionish-grey, loithout violet lustre : a faint bluish 

 tinge near bases. Fore-iving : costa with a narrow ochreous 

 edge ; sometimes an indistinct paler fascia on disc, widening 

 downwards from its origin on first median nervule. Hind- 

 wing : tivo submarginal rows of ^vhite lunular markings (of 

 which the inner is broader) between bccond subcostal and 

 submedian nervure ; the outer row ends with the three spots 

 which are more conspicuous than in $ : hind-marginal line 

 and its white edges very distinct. Under-side. — Jfhiter: 

 the markings brighter, clearer, and more conspicuous. 



Wallciigreu notes the very close affinity of Ilopffer's Orcji's to P. Erylus 

 of Godart, aud a comparison of the descriptions with Uopffcr's fij^uie and 

 with specimens lias convinced me of the identity of the two. The llgurc in 

 Peters' " Reise " sliows a ? in which the union of the outer row of lunules 

 with the inner edge of the iiiiid-margiual line gives the iU'ect of the "ycux 

 marginaux ii iris blanc " meniioned by Godart. The latter author notes a 

 character of the $ overlooked by Wallengren, viz., the dusky central 

 space in fore-wing, which is presented by all the nine spcciinens now b- fore 

 me. Mr. D'Urbau informs me that this is the species labelled " Jiih/ucus 

 Cerfhis, Boisd. MS." in the British Museum.
