January ; occurs sparingly also at Salto, near Valparaiso, 
in January.”—T. E. 
Mr. Reed erroneously quotes H. hegesia and E. claudia 
as synonyms of this species; although nearly allied and 
probably only geographical races of one type, they have 
as much claim to specific rank as have any other con- 
stant forms: constancy, and not amount of difference, 
constitutes a species.

Valparaiso and Valdivia. (See notes at end of paper). 
Owing to the resemblance which the female of this 
species bears to A. lathonioides (the sexes of which are 
alike) great confusion has arisen respecting it ; in Chili 
this has been complicated in consequence of authors 
there not examining Drury’s figure, and therefore retain- 
ing the synonym A. anna as the name of the species. 
As Reed himself says, ‘‘ La lamina que ahora doi de 
esta especie no es buena,” there can be little doubt that 
his figure is intended for B. cytheris, female. 
In a paper in the ‘ Scientific Proceedings of the Royal 
Dublin Society’ for 1879, p. 45, Mr. Kirby says :— 
‘‘Hubner’s figure of A. siga, and Reed’s of A. anna, 
represent the male exactly; Drury’s figure is too dark. 
The species which Reed (and probably Gay) describes 
as A. cytheris, Drury, is distinct, and must retain the 
name of A. montana, under which Reed originally 
figured it.”
