This is simply an occasional aberration of syhaniis, and gradations between 

 it and the next form, var. herculea, occur. 



Var. herculea, Butler. " Allied to F. sylvanus, considerably larger ; the male of a clearer, more 

 ochraceous colour above, and on the under surface of a more uniformly tawny colour ; the 

 secondaries not yellowish, as in P. sylvanus ; pattern similar. Expanse of wings 1 inch 

 7 lines. 



'• Female. Above bronzy brown or chocolate-brown, with cupreous reflections : primaries with a 

 yellow dot just above the basal third of submedian vein ; a cuneiform spot filling the base of 

 the first median interspace ; a bifid spot at the end of the cell; a series of five quadrate spots, 

 excised in front, crossing the disc obliquely from submedian to upper radial vein, and a trifid 

 spot across the subcostal branches, halfway between the cell and the apex, bufi : secondaries 

 with an angular discal series of five ochreous spots. Wings below with the markings paler 

 tlian above, the spots creamy whitish or pale bone-yellow ; disc of primaries round the 

 borders of the oblique series of spots olive-brown ; external angle and outer border whity 

 brown: secondaries bronzy olive-brown, the discal series consisting of six spots ; anal angle 

 broadly ochreous ; outer border tinted with ochraceous ; palpi white ; body below bluish

A. sylvanus appears to be a common insect in Japan, Corea, North and 

 Central China, and also in Amurland. It exhibits considerable variation, 

 and the specimens arc nearly always larger than those from Europe. 



Selas, Mabille, from Tliibet, is a form of A. sylvanus Avith the upper 

 surface of the fore wings unicolorous, as in var. venata, Bremer; the under 

 surface is also almost destitute of markings. The same form occurs as an 

 abeiration in (Jhina and Corea. 



Aninrensis, Mabille, is a very worn example of A. sylvanus, and when fresh 

 probably represented the form described by Hutler as herculea. 



iJistriljution. Europe, Northern and Western Asia, the Altai, Amurland, 

 Japan, Corea, North and Central China.
