hoary to a little beyond middle ; lobe with a narrow silvery edging 

 interrupted by base of tail. Cilia in fore wing white from apex to 

 lower radial nervule, below that fuscous ; in hind wing dark red 

 with a fine basal line of fuscous. Underside. — Deep ferruginous 

 red, ivith numerous thin, silvery, dark-edged spots, arranged as in 

 C. harpax {Fahr.), hut much more attenuated, and in hind wing form- 

 ing more continuous, less macular, transverse series. Fore wing : 

 a broad basicostal creamy border for about one-third of length of 

 wing ; a rather indistinct lilacine cloud over upper part of disk ; 

 below median nervure a conspicuous, slender, elongate fuscous- 

 edged white marking, curved upward at its inner extremity and 

 lying longitudinally; a similar but much longer marking, bent 

 downward at its outer extremity, between 1st median nervule and 

 submedian nervure : these two markings represent the much 

 thicker, more transverse ones in harpax ; inner-marginal border 

 only narrowly and faintly pale fulvous ; apical silvery spot only 

 of submarginal series well-marked, elongate, obhque. Hind 

 iving : disk with a faint but extended lilacine cloud ; discal series 

 of s-ilvery markings forming an almost continuous irregular streak 

 angulated inferiorly ; submarginal series of small spots very indis- 

 tinct, scarcely darker than ground-colour, except at angulation 

 immediately before anal angular lobe, where tv\o are silvery, sub- 

 linear, and dark-edged. 



Front of head, palpi, first and second pairs of legs (the first 

 being very densely hairy almost to end of tarsus), and under edge 

 of third pair all of the same creamy tint as the basicostal border of 

 the fore wings. Antennae without white bar beneath at base of club. 

 The distinguishing characters of this species of Chrysorychia 

 are :— on the upperside, the extremely dark red (in some lights with 

 a faint purplish gloss) of the discal patches, and the limitation of the 

 hind-wing patch (whereas in C. amanga and C. harpax the red 

 extends over the whole surface except a small basal portion) ; and, 

 on the underside, the very deep red ground-colour, the thinness and 

 regularity of the silvery markings, the very peculiar elongation 

 and whiteness of the two longitudinal streaks below the median 

 nervure and its first nemile in the fore wings, and the creamy 

 (not silvery-white as in C. amanga) colour of the basicostal border 

 in the fore wings. The very dense creamy hair, hke wool, clothing 

 the first pair of legs, and the absence of the inferior white bar 

 at the base of the antennal club, are also peculiar features of 

 C. cruenta, although the former is, to a much smaller extent, 

 exhibited also by C. amanga. 



Only two males of this handsome Chrysoryrliia were taken by 

 Mr. Selous— one in the Mineni Valley on 6th March, the other at 

 tlie Lopodzi Eiver on 2nd April.
