obliquely, in the opposite direction, toward the apex, before 

 reaching which it divides into two. (These two opposite 

 oblique stripes are straighter and more even than in either 

 of the allied species). Outside the second is a straight row 

 of faintly greyish spots, and others, still more faint, lie upon 

 the costal margin. Beneath the sub-costal nervure in the 

 middle of the wing is a broadly triangular grey spot, edged 

 beneath with white. Cilia ochreous or reddish preceded by 

 a series of faint grey marginal crescents. Hind wings grey, 

 tinged with reddish toward the apex, with a reddish marginal 

 line and pale reddish cilia. Female with antennce short, as 

 in the male, but more slender, and with extremely short 

 pectinations. Fore wings orange-red, orange-brown, chest- 

 nut-brown, or even pale umbreous, with the oblique white 

 stripes broader and whiter than in the male, but the marbling 

 and cloudy spots indistinct or absent. 



Undersides of the wings in both sexes dull orange-brown 

 redder at the tips ; without markings, but varying in shade in 

 accordance with the colour of the upper side. Legs rather 

 short, but all perfect, coloured in accordance with the shade 

 of colour of the fore wings. 



Extremely variable in size, especially in the female, of 

 which some individuals are nearly double of others in cacpansc 

 of wings. Varying also, as already indicated, in intensity of 

 colour, all the shades mentioned being united by imperceptible 

 gradations; also variable in the marbling, which sometimes is 

 distinct ; in other cases, where the colour is intensified, it is 

 obliterated. In the collection of Mr. A. J. Hodges is a male 

 of the precise shade of brownish of H. liipulinus, and only 

 distinguishable from it by the straighter oblique stripes. 



On the wing in the latter half of July and through 

 August. 



Larva \\ inch long; whitish and shining like ivory, with 

 deeply divided segments and deep wrinkles. Head orange- 

 brown with the mouth black ; dorsal plate on the second
