ON EUROPEAN BUTTERFLIES. 25 



Pyrameis (?) Ionia, Kind. 

 Vanessa Ionia, K., Eversm. Staud. 

 Apatura Ammonia, Herr.-Sch. 

 Pyrameis (?) Ionia, Kirby. 

 I have never seen this species, of which there is probably 

 not a specimen in England ; but Mr. Bates, judging from 

 Eversmann's figure, tells me that it is not a Vanessa or a 

 Pyrameis, but a Junonia, allied to some African species. 

 The genus Junonia is distinguished by the following cha- 

 racters : — 



Eyes naked, antennae slender, fore-wings nearly triangular, 

 emarginate ; hind-wings rounded or angular. 



It should be placed at the end of the Vanessides after 

 Pyrameis. 



Neptis Aceris, Fab. 

 The larva feeds, in Java, on a species of Hedysarum. 

 I overlooked this remark when describing the larva from the 

 figure in Messrs. Horsfield and Moore's Catalogue. 



CcENONYMPHA CEdipus, Fab. 

 Larva very similar to that of C. Pampkilus, but rather 

 narrower, clear green, with darker dorsal, and yellowish-white 

 lateral streaks. Head and feet olive-green, the latter rather 

 lighter. On Iris Pseudacoi'us. VII. — IX. ( Assmuss, Stett. 

 E. Z. 1863.) 



CcENONYMPHA DaVUS, HaW. 



Larva green, w^ith 6 white lines. Pupa suspended by the 

 tail ; green, with 3 dusky stripes on each wing-case. On 

 cotton grass, near the roots. V. (J. Chappell, Ent. W. Int. 

 i. 35.)
