parts of the south of England ; but it appears to be 
very rare in the north. It presents several varieties, 
of which the most remarkable is that named P. Py- 
ronia by Hiibner, represented on our 13th Plate, 
fig. 1. It has the upper wings blackish at the base, 
with a few' yellow spots, the rest of the surface, as 
far as the black border, likewise yellow, the nervures 
alone being black. The hinder wings are entirely 
dark brown, with a row of small yellow spots towards 
the margin, and a few others in the male near the 
base. The under side of the upper wings is yellow 
at the base, with large spots of black, the middle 
also black, and the extremity yellow ; of the hinder 
pair, black at the base, with yellow spots, and a broad 
central band of white intersected by black veins. 
This beautiful variety has been found near London.
