where ako the largest specimens are found. This tendency 

 to darker banding seems to increase in frecinency both north- 

 ward and westward. In Sutherlaudshire the bands are of 

 constant occurrence, and remarkably dark and complete, or 

 else are more definitely broken up into black spots ; and this 

 last modification becomes especially marked in the Hebrides, 

 specimens from those islands being sometimes ornamented 

 with five large black spots, two attached to the first line, 

 thi'ee to the second. Very striking specimens showing this 

 variation are in the collection of Mr. A. P. Grifiiths. In 

 Ross-shire a different tendency seems to be shown, the 

 central baud being sometimes wholly filled with dark brown 

 colourino', but there is not the defined seiiaration which 

 could be held to constitute a local race. There is something 

 in this nature in the Shetland Isles, iu that the size of the 

 specimens is less, and their wings are a little narrower, while 

 the darkening of the central baud, or its margins, is accom- 

 panied by a general intensifying of the usually faint rippled 

 markings over the remainder of the wings, giving a generally 

 darker and also sharper aspect to the individuals from these 

 islands. At the same time, some of these specimens are 

 brightened by the appearance of a narrow wliitc stripe, 

 broken into loops, in the middle of the central band ; such 

 an example is in the collection of Mr. F. J. Hanbury, while 

 the Rev. Joseph Green has one iu which the white stripe is 

 clear and unbroken ; Mr. Sydney Webb another in which it 

 is very broad but divided by the darker norvures ; and Mr. 

 S. J. Capjier a little specimen in which it separates extremely 

 dark brown bands. This white stripe has been seen in 

 English specimens, there being one iu Mr. Webb's collection 

 in which it sharply divides the deep black-brown clouding of 

 a full-sized banded specimen. In Ireland, along with the 

 general range of variation, there is a leaning rather towards 

 uniformly brown tints, the ground colour haviug a brownish 

 shade, which becomes stronger in the central band ; this is 

 most frequent along the western coast, and in the smal
