106 NOTITATES ZOOLOGICAE XXIV. 1917. 



49c. Satynis (Satynis) sylvicola holli Oberth. 



Satyrue sylvicola var. holli Oberthiir, Etud. de Lipid. Comp. Fasc. III. p. 275. pi. xvi. ff. 36-37 

 (1909) (Blida lea Glaciferes). 



This race is much the smallest and palest found in Algeria. Several of 

 the specimens from Captain Holl are labelled " Environs d'Alger," but I beheve 

 he never got it elsewhere than at Blida.

50. Satyrus (Satynis) fidia fidia (Linn.). 



Papilio fidia Linnaeus, Syst. yat. edit. xii. vol. i. part ii. p. 770. No. 138 (1767) (Barbary). 



This species occurs in three distinct races in Algeria. The typical fidia 

 fidia is very large, of a blackish slate-grey above with a bluish lustre ; in between 

 the ocelli on the forewing above are two largish white spots. On the under- 

 side the pattern is very strongly marked. The ocelli are hardly, if at all, marked 

 with yellow in the $ above.

22 Ain Draham, Tunisia, September 1911, Faroult. 

 42 Envii-ons de Batna, August 1912-1914, Nelva. 



The Batna specimens are slightly smaller than all the other typical fidia, 

 but cannot be separated from them. 



The British Museum has 6 Mauretanian specimens : 3 Algeria, Leech and 

 Hewitson colls. ; 1 Constantine Hm. ex Elwes coll. ; 2 N. Africa, Salvin God- 

 man coll. 



50a. Satyrus (Satyrus) fldia hebitis subsp. nov. 



Mr. Oberthiir described his fi^lia tninor from Sierra Alta Albaracin, Spain^ 

 and the figures (Etud. dc Lipid. Comp. Fasc. III. pi. cxxv. ff. 1108, 1109) show it 

 to be a very dark insect with no yellow round the ocellus of the ?. On the same 

 plate Mr. Ob?rthiir figures a much larger $ from Geryville, Sud Oranais, which 

 has large orange rmgs to the ocelli and is much paler ; this he also places under 

 his /. minor. There are in the Tring Museum 91 specimens from Guelt-es-Stel 

 which at once strike the eye as bemg very distinct from the large fidia fidia of 

 the coast regions. While being smaller than /. fidia, they are much larger than 

 Spanish /. minor, and are not only paler in colour, but appear much duller hi 

 shade ; these I propo.se to separate as a subspecies as above and include in it 

 the Geryville form. 



3. Differs from /. fidia in being considerably smaller and above much paler, 

 more brownish, and much duller, the bluish lustre being entu-ely absent and 

 replaced by a dull bronzy wash. The two white spots between the ocelli are 

 much smaller and even absent in some specimens ; below the pattern is less 

 sharply marked, and the greys are less pure, more bro\vnish. 



?. Differs above in being as a rule smaller and brownish mouse-grey, not 

 blackish slate-grey, while the ocelli have large yellow wings not found in coastal
