Variety of Argynnis aglaia. 
This beautiful variety of Argynnis aglaia was captured this year 
(1891) at Bevendean near Brighton, and exhibited by me at the City 
of London Entomological Society’s meeting of November 19th. The 
specimen differs essentially from the typical male of this species in 
the great increase of the size of the black spots, and consequent 
suppression of the ground colour. It will also be noticed that the 
sides are slightly asymmetrical, the right pair of wings being much 
darker than the left. The most important points of variation in the 
fore-wings, compared with the type, are as follows ; — (i). The blending 
of the second and third costal streaks into a black patch, the excessive 
development of the discoidal blotch (or fourth streak), and the union 
of the fifth and sixth streaks into another blotch. (2). The union of 
the lunular black marks parallel to the hind margin with the parallel 
row of dots, thus forming a transverse series of black patches. (3). The 
excessive enlargement of the zigzag series of black marks running down
