Matura, 25th November, 1874. 



This species was taken at light ! Mr. Hewitson was 

 doubtful whether or not it was a variety of Herrich- 

 Schaffer's species, as the border of primaries above is 

 narrower, and on the underside there is no white spot 

 near the costa of secondaries; but in these characters it 

 approaches the figures in the " Illustrations of Diurnal 

 Lepidoptera," though it differs from the latter in having 

 no white spots on the under surface of primaries; I am 

 therefore content, for the present, to consider it a variety 

 of -S. punctum. In these little things, of whose varia- 

 bility we know nothing certainly, it is safer not to establish 

 species upon single examples.
