ARICIA MEDON. 239 



margin of the forewings. I should put them down as var. gallica, the 

 underside ground-colour being greyish, and the upperside orange-red 

 spots being, on the average, not quite so well developed as in the Syrian 

 specimens, though I must admit that the difference is slight. In the 

 later brood, or broods, these spots are not more developed than in the 

 first brood. The ground-colour of the underside of the wings varies 

 from a slightly more yellowish-grey than in the spring specimens 

 (Erenkeui, 10, vi., 1911, Belgrad Forest, 16, vi., 1911), through 

 various shades, to a rich and warm shade every whit as bright as in my 

 brightest Syrian specimens. My largest medon from near Constantinople 

 is 32- 5mm., a male. I find the average size of the spring specimens less 

 than that of the later broods. With regard to the dates of appearance, 

 etc., here given, I may note that 1911 was a very late year at Con- 

 stantinople. Warm weather, save for a brief spell in the first week 

 of April, could not be said to have begun till May 2nd." 



Grund notes that in Dalmatia var. omata occurs as the spring 

 brood, and var. calida as that of the summer. Aigner-Abafi reports 

 the same forms from Hungary, but adds that in summer var. aestiva 

 is more usual. 



Staudinger notes the Greek specimens from Naxos, Attica and 

 Parnassus as having, both in the early spring (March and April) 

 and early summer (May and June) full bands of orange-red spots 

 reaching, or almost reaching the costa, the first brood being invariably 

 light grey beneath and the second brown, deep brown in the $ s, the 

 former being of the form which he afterwards called var. omata, and 

 the latter the original examples of his var. aestiva. 



The specimens from Asia Minor (Broussa, Amasia), show much 

 the same variation. The underside of the spring brood, however, is 

 of an exaggerated form of var. omata, being so white as almost to 

 equal ab. albicans, Auriv., in this respect ; they differ from this 

 form on the upperside in the pronounced orange-red band on both 

 wings ; the brown tint of the underside in the second brood is also 

 deeper than in the Greek specimens, and differs very little in the two 

 sexes. On the upperside they have a slightly broader orange-red 

 border, but should, perhaps, rather be reckoned as var. aestiva than 

 var. calida. 



We have no data as to the first brood in Syria, but Graves observes 

 (in litt.) that " the summer and autumn specimens are of a bright 

 ground-colour on the underside," which he describes as "a warm 

 brownish or greyish-yellow, sometimes approaching orange." He 

 a,dds : " the band of orange-red submarginal spots on the upperside of 

 both wings is well developed, especially in the $ . In most of my $• 

 specimens it reaches the costal margin of the forewings, though the 

 spot nearest the margin is often obscure." On the underside forewing 

 the costal spot of the discal row is often present. At Damascus 

 specimens are taken in September with a duller, greyer ground-colour 

 on the underside, especially on the forewings ; the September 

 specimens from Aleih, 2,500ft., are, on the other hand, particularly 

 bright, both in the ground-colour of the underside and in the orange 

 band of the upperside. 



Persian specimens in the Brit. Mus. coll. from Urumiah and 

 Orchabad have a good deal of orange on the upperside ; those from
