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 Lomiea.
