the hind-wings, and tho costal and apical borders of the fore- 

 vnngs are pale sandy-brown ; and the spots constituting 

 the central row of the hind-wings are rather less irregular 

 and confluent than usual ; while, in the fore-wmgs, the 

 two spots immediately below the median nervure are 

 only indicated by some blackish scales. The colouring 

 of the body is more ochreous, and the alternate markings 

 of the cilia more conspicuous than usual. 



The description given by Wallengren (Sv. Akad. 

 Handl. 1857, p. 44), under the name of Chrysorycliia 

 Thyra, Linn., does not at all agree with the Linnean 

 diagnosis, noting a row of fuscous spots on the upper- 

 side in both ^vings, which is wholly wanting in the Lin- 

 nean species. Wallengren's insect is probably a well- 

 marked ? of Z. Chrysaor.

Of this very variable species, the numerous examples 

 sent from Koesberg, Maseru, and the Maluti Mountains be- 

 long to the form Taikosama, Walleng. (Svensk. Ak. Handl. 

 1857, p. 43), one ? agreeing with Wallengren's descrip- 

 tion in every particular. Cramer's figure of tho under- 

 side is very roughly executed, the important hind-wing 

 markings being carelessly treated ; but 1 have concluded, 

 after much examination, that it represents a vinous-tinged 

 ? of the " Var. B," described in my Catalogue as so 

 abundant near Cape Town.* From the latter, the Ba- 

 suto-land form seems constantly to differ in the smallness 

 and separation of the glistening spots forming the third 

 transverse row on the underside of the hind-wings, and 

 in the distinctness and separation from that row of the 



* This being tho case, the dark form of both sexes (in which the fnscoiis 

 spots on tlie fnlvous of hiud-wiuj^s are united to the hind-niargiual edging), 

 described by nic as tiie tyjiical fomi, will have to rank as a variety of 

 Cramer's insect. Felder's Nais Almeida (lleise der Novara, Lep., p. 261', 

 pi. xxxii. f. 25, 26) is this dark form ; and I cannot follow Mr. Bntler 

 (Cat. Fab. Lep. B. M., p. 17G) in regarding Almeida as "a slight variety" 

 of Nycctus, Cramer, the latter being totally different in the hind-wing 

 markings of the underside.
