On the Char of Great Britain. Ill 



genus Nepheronia, although in this case the green colour 

 is concealed by the opaque superficial scales. The rapid 

 change of tint noted by Burchell is clearly associated 

 with this unusual development of pigment between the 

 wing-membranes, and it is probably caused by desic- 

 cation.

this date.

West wood's list does not mention any individual caught on

Westwood's list adds two more individuals captured at 

 Porto Redl 2Q. 2. 29 and 6. 3. 29. See note on 1268. 



The data of this species appear, as A. 19^ in Westwood's 

 list of Acraiinse. Opposite the very imperfect records West- 

 wood had written " Ceth. Dido." Another list, on a small 

 slip of paper, is in Westwood's handwriting, and this contains 

 all the data here recorded except those of 1261. This 

 separate list is headed ''' Dido.^''
