Var. VenatEj Bremer & Grey. — " Alis supra : fiilvo-ocliraceis, nigro-marginatis at venatis, ajiice 
non nihil obscuriori, linea discoidali nigra ; subtus : omnibus fulvo-ochraceis, anticis basi 
nigra. 
" Espans. alar, antic, unc. 1|." (Brtmer 4' Gretj, 1. c.) 
This is simply an occasional aberration of si/lvaniis, and gradations between 
it and the next form, var. herculea, occur. 
Var. herculea, Butler. " Allied to F. n/lvamis, 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. 
'■ Fi-male. Above bronzy brown or chocolate-brown, with cupreous reflections : primaries with a 
yellow dot just above the basal third of submediau 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 trifld 
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 
than 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 brouzy olive-brown, the discal series consisting of six spots ; anal angle 
broadly ochreous ; outer border tinted with ochraceous ; palpi white ; body below bluish 
grey. Expanse of wings 1 inch 7j lines. 
'• One pair only was obtained. Xikko." (Butler, J. c.) 
A. sylvanus appears to be a common insect in Japan, Corea, North and 
Central China, and also in Amiuiand. It exhibits considerable variation, 
and the specimens are nearly always larger than those from Europe. 
Selas, Mabille, from Thibet, is a form of A. syhamis with the upper 
surface of the fore wings unicolorous, as in var. venata, Bremer; the under 
surface is also almost destitute of markings. Tlie same form occurs as an 
aberration in China and Corea. 
Amurensis, Mabille, is a very worn example of yi. si/lcanus, and wlieu fresh 
probably represented the form described by Butler as herculea. 
iJistribution. Europe, Northern and Western Asia, the Altai, Amurland, 
Japan, Corea, North and Central China.
