species ; outside this is a honlei' (if white, shading off into a 

 series of tawny clouds whicli almost, or quite, form another, 

 more narrow, transverse hand, edged outside by the sub- 

 terminal line, white and excessively rippled, or looped between 

 tlie nervures ; beyond, tin- hind-marginal region is clouded 

 with tawny-Iirown, the upper portion of this incomplete 

 cloudy band of colour being cut oflT by a white cloud which 

 runs into tlie a]iex of the wing ; nervures in this clouded 

 area streaked with black-brown, and tipped with wiiite 

 crescents, by the sides of which are marginal blaek duts; 

 cilia jiale brown, intersected with dark brown, and dashed 

 with white. Hind wings long, rather narrow, rounded 

 behind, brownish-white with a more smoky tinge from thf 

 middlr to the dorsal margin; central spot small, smoky- 

 black ; cilia white, dusted with brown. Female similar, but 

 with a rather stouter body. 



Underside of the fore wings shining brownish-white ; second 

 line reproduced. angulate<l, smoky-l>rown, shaded oH' inwardly : 

 followed by another smoky-browu stripe, and beyond tliis by 

 a faint clouding of the same. Hind wings white, dusted 

 with brown; central spot distinctly dark brown; followed 

 Dy two obscure slender brown transverse lines ; hind margin 

 edged with brown. 15ody and legs pale brown. 



Variable, as already indicated, in the form of the cential 

 band, which, though so often interru))ted that the insect 

 received the common name of the " Uroken bar." is yet very 

 often entire, and even sometimes almost broad. In liill 

 districts from Cannock Chase northward the ordinary form 

 is almost entirely rejilaced by one in which the wings are 

 very slightly narrower, their colour whiter, the tawny cloud- 

 ing deeper but more I'estricted, and the central band darker 

 and /'.■itialli/ romphir. Instances are not, however, wanting in 

 which this race shows the character of the " broken bar."
