spot placed near the costa and directly above that last referred to ; 

 one has a fourth spot towards apex. On the other hand, there are 

 specimens with but the slightest trace of a spot at anal angle. As a 

 rule the female is without markings, but sometimes a brownish spot 

 appears at anal angle, and one example of this sex in Fryer's col- 

 lection has the basal spot also well developed. 



There is considerable diiference in size, as will be seen by the 

 following measurements : — 



Smallest cJ 24 millim. Largest d 36 millim. 



„ $ 33 millim. „ 2 46 millim. 



Thus it will be seen that the largest $ is almost twice the size of 

 the smallest d in wing expanse, whilst this last is one third less in 

 expanse than the largest S .

Of the type of this species, which Bremer says is very like 

 helladia, Cram., I have no specimen, but there were two examples of 

 var. piperita in Fryer's collection taken at Oiwake. These very 

 closely resemble Porthesia snelleni, Stand., Rom. Mem. sur Lep.

A long series from various parts of Japan and Corea. Some of 

 the specimens have two distinct black spots near apex of primaries, 

 others have only one, whilst some other examples again have not a 

 trace of any such marking. Further, there are two speciniens which 

 appear to me to he varieties of this species ; one of these is identical 

 W\i\x fiavinata. Walk., and the other with conspersa, Butl. Without 

 a longer series it is not possible to form an opinion as to the legiti- 

 mate rank of these two last.

Allied to A. subflava var. piperita but smaller, the primaries are 

 of a deeper yellow sparingly sprinkled from the base nearly to the
