22 DIURNAL LEPIDOPTERA. 



No. 16. — A. Aphrodite. — One of our most common species. 

 Its successive generations are constantly ajDpearing during 

 spring and summer, but the greatest number are met with 

 early in autumn. The beautiful display of large and numer- 

 ous silvery spots on the under surface of its wings, render 

 it an interesting object to the eye of every observer. 



No. IT. — A. Bellona. — This smaller species is equally 

 abundant with the preceeding. The food of the larva is 

 unknown to me. 



No. 18. — Melit^.a Phaeton. — In one instance only have 

 I seen this species in Northern Ohio. A few specimens, 

 captured at Dayton, I observed in the cabinet of the late 

 William Jenison, of that city. 



No. 19. — M. Myrina. — In the same cabinet I observed 

 this species, from the same locality, and have met with it 

 very rarely at the north. Like Argynnis Idalia, it is abun- 

 dant in the States of Connecticut and Wisconsin. 



No. 20.— M. Tharos. — A common species. 



No. 21. — Vanessa Antiopa. — Though a species introduced 

 from Europe, it has become very common. It often, in its 

 perfect state, survives over winter, and may be seen flying 

 during the first days of spring. The larva, which often feeds 

 on the foliage of the lombardy poplar, excited strong preju- 

 dice, some years since, against such trees, from an errone- 

 ous belief that their tenant was venomous, like Cleopatra's 

 asp. 



No. 22. — y. J. Album. — Appears in small numbers during 

 spring and again in autumn. It seems to have a predilec- 

 tion for ripe or decaying fruit, and often visits our cider 

 mills, where apples are collected in large quantities. The 

 food of its larva I have not been able to ascertain. 



No. 23.— V. Interrogationis. — Is frequently seen about 

 our hop vines, upon which its larva frequently feeds.
