NOVITATES ZOOLOGICAE XXIV. 1917. Ill 



ines. In ines the vein 1 along the abdominal area of the hindwing is single, 

 while in arge it is double, and forms a loop like in syllius Herbst., and in fact 

 I should at once say it was only a local race of that species if it were not for 

 the nervures on the underside being black instead of rufous as in syllius ; any- 

 how, it is certainly not a subspecies of ines. As to the distinctness of fathme 

 from ines, at first sight, and compared with most Algeiian and Spanish speci- 

 mens in collections, they are certainly much whiter, but when comparing a 

 series of 8 Tunisian specimens with 1,600-1,800 Algerian and 10 Spanish, I 

 confess that I cannot uphold the subspecific distinctness of the Tunis examples. 

 I find in the 1,000-1,500 Guelt-es-Stel specimens and in the El Kantara series 

 quite half which are as white as Tunisian specimens, though the Spanish ones 

 are certainly all dark, but not so dark as a number of Algerian ones. I there- 

 fore must reluctantly come to the conclusion that Herr Wagner's fathme can 

 only be considered as an aberration and must stand as ab. jathme Wagn. 



It is quite otherwise with the form from the west coast of Morocco : this 

 form is quite as white as if not whiter than Herr Wagner's fathme, but it is not 

 small, like the Tunisian examples, but has developed to a gigantic size. This 

 is described further on. 



The total series selected for the Tring Museum of Algerian and Tunisian 

 ines is 638.
