c? ? . A large North African form, corresponding to tlie equally enlarged 

 edition oi ■jfjopuU of the same conntries. The barpe is longer and distally narrower 

 than in ocell. ocelhitn, the oonieal tooth of the j)enis-sheath heavier, more .strongly 

 curved, almost elbowed. 



The specimen named apslioalis by Austaut is in the Tring Museum ; the 

 difference between it and ordinary specimens of nfl.a/Uicii.i is very slight. The 

 series of hybrids anstauti x atlanticus in the Tring Museum (11 si)ecimeiis) exhibits 

 considerable variation ; in some the rnsset-tawuy colour of the hindwing has nearly 

 disappeared ; the grey centre of the black patch of the hindwing is often transverse, 

 of irregular shape, rarely circular ; the aiitemedian lino bordering the dark discal 

 area of the forewing is often angiilate behind the l>ase of M-. 



Larva and pupa similar to those o^ ocell. ocellatd, but the head of the former 

 dark green, the horn uniformly grey-blue.

In opposition to Leech, who pronounced planus to be identical with orcU'tta, 

 iStandinger maintained that there were some differences between the two in c )lour 

 and pattern which justified the separation oi planus from ocellata, if not as a species, 

 at least as a " good " geograjihical race. The distinguishing characters pointed out 

 l)y Staudinger in 1NU2 were snbseipieotiy said by Leech to be (piitc unreliable. 

 Writers on I'alaearctic Lepidoptera mention planus generally as donbtlully distinct, 

 or as a slightly different form of ocellata. It is very ciirions tliat not one of the
