138 ACTIAS MAENAS, VAR. ISIS. 



margin of the forewing is bent inward on rib 5 — 7, so 

 that the apex on rib 8 is more protruding. The top of 

 the lunule is more pulled down to the base, the distinct 

 brown band near the base starts straightly from ^/^ of the 

 foremargin to ^/^ of the innermargin, the brown flexuous 

 streak behind the lunule does not lie in the middle between 

 the latter and the outermargin, but nearer to the lunule, 

 so that the distance between streak and outermargin is 

 twice that between streak and lunule. Before the apex in 

 the anterior margin is a long spot; before the innerangle 

 in cells lb, 2 and 3 are three little round violet spots. 

 Outermargin violet-brown. 



On the posterior margin the distinct brown basal band 

 is in the middle between base and ocellus and starts to 

 the dark violet-brown tail. The outer, brown, flexuous 

 transverse streak is indistinct near the ocellus and joins 

 the basal band. The undulated violet-brown margin becomes 

 distally broader and joins also the dark tail. Tail 7 

 niM. ; -/g is violet-brown, much darker than that of maenas, 

 the flag is pale yellow with violet-brown on a part of the 

 margin. Ocellus identical with that of maenas. 



Below the prime-colour is paler, bands near the base 

 absent, lunule replaced by an ocellus, which is not so 

 large as that on the posterior-wing. The two ocelli on 

 the underside are coloured like those of the hindwing on 

 the upperside, but a little paler. The flexuous streak on 

 the wings is nearer to the outermargin than that of the 

 upperside. The outermargin is covered with a grayish red 

 dust, more intensively on the anterior-wings than on the 

 posterior-ones. The tail is wrinkled at the extremity ; it 

 is grayish red, except the last little part. 



Finally I will say, that there must have been a fifth 

 variation, according to the four degrees of transition from 

 red-brown to yellow, which was entirely dark red-brown 

 with four figures on the tops of the cells. The variety 

 isis is the eldest one, that is to say, these moths have 

 retained longer their original colour. The females are very 

 highly developed; the males show us several degrees of
