NOVlTATES ZOOLOGICAE XXIV. 19! 7. §9 



Miss Fountaine records a single specimen from Sebdou, June 1904. 

 Mr. Blachier records a specimen from Immentala, Morocco. 

 Mr. Joannis records this species from Oued Kadamellet, north of Air, 

 September 1905, M. R. Chudeau. 



19. Teracohis Uagore (Klug). 



PorUia Uagore Klug, Symh. Phijs. fol. g. p. I. pi. ri. ff. 5-8 (1829) (Ambukohl). 



This insect is recorded by M. de Joannis, Brdl. Soc. Entom. France 1908, 

 p. 82, as having been collected by M. R. Chudeau, Oued Kadamellet, north 

 of Air, September 1905. 



20. Teracolus chrysonome (Klug). 



Poraia chrysonome Klug, Symh. Phys. fol. g, p. 2. No. 0. pi. vii. f=E. 9-11 (1829) (Ambukohl). 



In the Ann. Mag. Nat. Hist. (8), xvi. p. 247. No. 3 (1915) I quite correctly 

 enumerated Herr G. von Schwoppenburg's four Ideles specunens as Teracolus 

 hdvolus But!. Professor Aurivillius in Seitz places helvolus, however, as the 

 dry-season form of chrysonome, and I believe he is right, and that in absolute 

 desert areas like Somaliland and the Hoggar Mountains the wet-season form 

 chrysonome does not occur. 



In the Ideles specimens the mauve bands and spots are not quite so much 

 obliterated as in 5 <J(^ I have from JubUando, British East Africa, but they 

 are not at all golden yellow with bright mauve bands as in typical chrysonome 

 collected by my brother N. Charles Rothschild at Shendi, and which I have 

 also from Suakim and the Nandi country in British East Africa. 



4 Ideles, Hoggar Mountains, March 1914, Geyr von Schweppenburg. 



This^ species should stand thus : 



Teracolus chrysonome (Klug). 

 gen. vern. chrysonome Klug. 

 gen. aest. helvolus Butl. 



These four specimens in the Tring Museum are, I believe, the only known 

 Mauretanian examples of thLs species, except those recorded by Joannis as 

 collected by M. R. Chudeau, viz. Oued Tessamak, Adrar, June 1905; Oued 

 Tidek and Oued Kadamellet, north of Air, September 1905. 



21. Colias hyale (Linn.). 

 Papilio hyale Liuuaeua, Syst. Nat. I. p. 469. No. 71 (1758) (Europe, Africa). 



I have never seen any Mauretanian hyale ; in fact I have never seen true 

 hyale from any part of Africa ; the subspecies hyale marnoana Rogenh., how- 

 over, occurs in Abyssinia and the Soudan. Mr. Oberthiir, when he says that 

 hyale as we understand it to-day is not the hyale of Linnaeus, quotes the twelfth 

 edition of the 8y sterna Naturae, in which is added the habitat " America Septen- 

 trionali." In the tenth edition only Europe and Africa are given, and the 

 quotation of the Fauna Svecica is not included ; I therefore think, despite the 

 discrepancies of the diagnosis, we can quite conscientiouslj- assume that wo 

 are applying Linnaeus' name hyale to the butterfly he gave it to in his tenth 

 edition.
