NOVITATES ZOOLOGICAE XXIV. 1917. 105 



In the British Museum Mr. Elwe.s has himped all these insects together under 

 statilinus, which is absolutely WTong. Dr. Seitz, in his GrossscUmetterlinge der 

 Erde, places hansii as the Mauretanian representative of statilinus, and sylvi- 

 cola as that of fatiM ; but remarks in parenthesis that they are probably good 

 species, though our knowledge {i.e. really Dr. Seitz's) was too scanty to decide 

 this. One thing is certam, the larvae of hansii and sylvicola only show the same 

 differences as statilinus and fatiut, viz. the much larger head of hansii, but they 

 are otherwise as imagos so different, both from each other and the two forms 

 from north of the Mediterranean, that till we have dissected them I prefer to 

 treat them as distinct species, especially as sylvicola occurs in Algeria in several 

 distinct races.] 



48. Satyrus (Satyrus) hansii Aust. 



Saiyrus hansii Austant, Le Natvraliste, vol. i. p. 138 (1879) (Daya). 



The Tring Museum has no specimens of this species. The British Museum 

 has 9 specimens : 5 Algeria, Crowley bequest ; 3 Mauretania, Grum-GrshimaUo 

 coll., ex Elwes coll. ; 1 Sebdou, 1880-1882, Dr. Codet ex Elwes coll. 



Miss Fountaine records it from Sebdou, Jidy — August 1904. 



49. Satyrus (Satyrus) sylvicola sylvicola Aust. 



Satyrus sylvicola Austaut, Le Naluraliste, vol ii. p. 284 (1880) (Sebdou). 



Tliis race is the darkest of the four races of sylvicola described from Algeria. 



4 Titen Yaya, August 1915, Rotrou. 

 20 Les Pins, August 1915, Rotrou. 



The British Museum has 9 specimens, all without data : 3 Mauretania, Grum- 

 Grshimailo coll. ex Elwes coll. ; 1 Algeria, purchased Janson ; 5 Algeria, Crowley 

 bequest. 



49a. Satyrus (Satyrus) sylvicola oberthueri >ubsp. nov. 



Satyrus sylvicola var. lamhessanusOhetth.\iT, Etnd. d'Entom. Comp. Fasc. X. p. 170 (1915) (Lambese). 



Mr. Oberthiir gave to this race of sylvicola the r.ame lambessanus, but 

 Staudinger in Cat. Lepid. Palaear. Faung. Stdgr. and Reb. p. 58. No. 377 a. (1901) 

 gave to the Eastern race of Satyrus abdelkader the name of lambessanus, and 

 one cannot have two identical subspecific names in the same genus ; therefore 

 I rename this race oberthueri. 



It stands exactly intermediate between «. sylvicola and s. cinerea. 



95 Environs de Batna, August 1912-1914, Nelva. 



The British Museum has 2 Environs de Batna, August 1910, Rev. A. E. 

 Eaton. 



496. Satyrus (Satyrus) sylvicola cinereus Oberth. 



Satyrus fauna var. cinerea Oberthiir, Bull. Soc. ErUom. France, 1907. p. 344 (Yakouren). 



I do not possess this form, and possibly the only other man who may have 

 it besides Oberthiir is Dr. Nissen.
