ERONIA. 



Dr. Boisduval proposes the name of Dryas Leda, considering it the type of a new genus. It differs, however, from 

 Eronia Argia only in colour and the rather more delicate texture of its wings. 



There are six distinct sections in the genus, as far as regards colour and the outline of the wings. Eronia Clcodora 

 and Eronia Idotea have both pairs of wings bordered above with fuscous, below with beautiful shades of brown, with a 

 satiny lustre ; the posterior wings have the outer margin sinuate, almost dentate. 



Eronia Argia and Eronia Thalassina have the anterior wings more pointed at the apex, less broadly bordered with 

 black, especially towards the anal angle ; the posterior wings in the males not bordered with black, and the apex only 

 of the anterior wings below clouded with satiny brown. 



Eronia Pharis has the wings nearly as round as the genus Pontia, and of as delicate a texture; the apex of the 

 anterior just touched above with black, below varied with brown ; the posterior wings above immaculate, below 

 sometimes nearly immaculate, at others varied with large clouds of satiny brown and silvery white. 



Of Eronia Leda I have only seen the specimen in the extensive collection of Mr. H. G. Harrington. It has 

 much the form of Eronia Buquetii ; is of a pale sulphur-yellow above, with the apex of the anterior wings fulvescent, 

 the margin itself and six spots before the apex ferruginous. Below ; the apex of the anterior wings is broadly rufescent, 

 marked with three silvery spots encircled with ferruginous, corresponding in place with the first, third, and fourth of 

 the upper surface. The posterior wings are sprinkled with numerous rufous clouds, and have beyond the cell a series 

 of six silvery spots encircled with ferruginous. 



Eronia Buquetii has precisely the dull white upper surface, the slight black tip to the anterior wings, and the 

 shining greenish white under surface of the posterior wings marked with a sub-ocellated silvery spot, which 

 distinguish some species of Callidryas, as Callidryas Minna ; but these are the only points of resemblance. In the 

 form of the antenna? and palpi, and in the neuration of the wings, it exactly coincides with Eronia Cleodora ; in the 

 form of the wings, more nearly with Eronia Argia. These species are all African. 



Eronia Valeria and Eronia Iobrea have very much the appearance of some species of Danais. Their wings are 

 more elongate ; whitish, greenish, or yellowish, bordered with black externally, and along the nervures. The former 

 of these is Indian, the latter Australian.
