NOVITATES ZOOLOGICAE XXI. 1914. 309 



caught on March 22. We ourselves in 1912 only captured 2 cJ c? and 1 ?. The 

 characteristic yellow wash on the underside of the hindwings, which is the dif- 

 ferentiating mark of the southern form hjllus, is scarcely perceptible in some 

 specimens ; while others have the whole hindwing on the underside yellow. They 

 vary considerably above in the width of the dark margins. 



Nymphalinae. 

 21. Pyrameis cardui (liinn.). 



Pap'dio cardui Linnaeus, Faun. Sure. p. 27G. No. 1054 (1761) (Sweden). 



There are four June specimens sent by Victor Faroult in 1913 to represent this 

 exceedingly common species. 



22. Argynnis maja seitzi Fruhst. 



Arrjynim maja se'dzi Fruhstorfer, Int. Ent. Zed. ii. No. 12. p. 69 (1908) (Aures Mts., not Alger, error). 



This species is rare on the Central " Hants Plateau.\." Victor Faroult sent 

 3 c? (? and 2 ? ? from Guelt-es-Stel from June. The type came from the Aurfes 

 Mountains, not Alger, as published by Fruhstorfer ; it is therefore worth while 

 comparing specimens from the Tell and Kabylie with Batna specimens, which may 

 prove to be distinct. The amount of vadation is principally in the silver striping 

 below, though Oberthiir figures, vol. ix. of his Et. (Jomp., pi. CCXXXV., a lilac 

 variety and a partially melanistic one. 



LYCAENIDAE 



23. Callophrys rubi fervida Stdgr. 



Callophnjs ruhi var. fcrc'ula Staudinger, Stdgr. i Rebel, Cat. Lcp. Pal. Faun. p. 70. No. 476, b. 

 1901 (Spain). 



This si)ecies is not common in Guelt-es-Stel ; the collection contains 1 S 

 captured by us on April 16, 1912, and 8 (?c?, 3 ? ? caught on March 20 and 27, 

 1913, by Victor Faroult. 



24. Callophrys avis I'hapm. 



Caltophr//s avis Chapman, Ent. Rec. & Jouru. Var. vol. 21 p. 130 (1909) (Southern France). 

 Very rare in this district. 2 ? ¥ and 1 S April 1913 (Victor Faroult). 



25. Thestor inauritanicus (Luc). 



Pobjouiinalun uiaurilanicus Lucas, Expl. Ahj. Zuol. iii. p. 360. No. 39 pi. 1 f. 3 (1849) (Algeria). 



Much rarer than T. ballus. Victor Faroult got 11 c^c? and 5 ? ¥ in March 

 1013, and we got 4 <S S and 1 ? in April 1911 and 1912. 



The S S show a considerable variation in the e.vteut of the orange near lornus 

 of hindwing above. 



26. Thestor ballus (F.j 



Papilio ballus Fabricius, Maut. Ins. ii. p. 80. No. 729 (1787) (South Europe). 



Fairly plentiful ; Faroult sent 47 c?(?and 33 ¥ ? from the months of March 

 and April 1912, and we took 2 ¥ ¥ on April 26, 1911. 

 No appreciable variation.
