ally expanding over two inches, and the wings are brown ; the 

 fore-wings having an oblique sulphur-yellow band running from 

 near the base to just above the hinder angle. The hind-wings 

 are sub-dentated, with a short truncated projection at the anal 

 angle. On the under surface the band is white, and all the 

 wings are more or less obliquely striped with intersecting grey 

 and black lines, which are tinged with yellow towards the hind- 

 margins. 



Next to this genus Schatz and Rober place Smyrna, 

 Hiibner, which includes one or two Butterflies from Mexico 

 and Brazil, which were formerly placed near Agrias, Doubl., 

 bat the discovery of the larva proves that their true affinities 

 are with Gyncscia. They are much larger insects, measuring 

 over three inches across the wings, which are marked above 

 nearly as in Callizona aceste, but are of a deeper fulvous. The 

 hind-wings are dentated, and are slightly excavated on the 

 lower part of the hind-margin, and then produced at the anal 

 angle into two short obtuse prominences, with a slight depres- 

 sion between them. The under side of the hind-wings is 

 brown, covered with a number of bluish-grey curving and un- 

 dulating lines ; towards the centre runs a straight broad 

 whitish band, with irregular edges, and towards the hind- 

 margin is a row of variously-coloured eyes in several concentric 

 rings. 



THE GENUS IIYPOLIMNAS AND ITS ALLIES. 

 Hypolimnas, Hiibner, or Diadema, Boisduval, as it was 

 formerly called, is the typical genus of one of the most remark- 

 able sections of mimicking species in the Nymphalincc. The 

 Butterflies of this genus are large insects, generally expanding 

 three or four inches across the wings, which are rather broad. 

 The fore-wings are not much produced, and the hind-margin 

 is generally slightly concave. The hind-wings are rounded, 

 O." more frequently rather long, and more or less dentated,
