79. Apatura Flora, Edw. 



Expanse of wings about the same as A. Clyton. 



Male. — Both wings more excised than is usual in 

 Clyton, and the hind wings more prolonged and more 

 pointed 'at the anal angle. Upper surface of both wings 

 uniform bright orange ferruginous, except the area be- 

 yond the cell of the fore wings, which is of a deep shade 

 of ferruginous, blackened in the middle of the several 

 interspaces. The fore wings are scarcely at all obscured 

 at base, and the two rows of spots are bright orange 

 ferruginous, of the same shade as the general surface, 

 instead of being yellowish as in the usual Clyton. 



The hind wings have the base and inner margin but 

 slightly obscured, and a broad bright stripe extends from 

 the middle of the wing to the marginal band. The 

 ocelli lie in this field, and are large. The marginal band 

 of each wing is remarkably broad, so that on the hind 

 wings it nearly reaches the ocelli ; and, except in the two 

 interspaces next the outer angle, there is a total absence 

 of the submarginal crenated line always seen in var. 

 Ocellata of Clyton. Furthermore, there is an absence 

 of the light patch on costal margin. The peculiar shape 

 of the wings, the uniform bright shade of ferruginous, 

 extending even to the rows of spots beyond the cell, the 

 large ocelli, the broad marginal band, and the absence of 

 the crenated line and of the costal patch, strike the eye 

 at once. 



On the under side the pattern is as in var. Ocellata
