SPHINGID.-E. Yj 



tlie space of the costal half of the wing is occupied by red- 

 dish and yellowish clouds, broken up by irregular indented 

 blackish stripes ; towards the hind margin ai'e usually 

 indications of several dusky-whitish, double, curved lines or 

 even circles ; and on the hind margin the terminations of 

 the nervures are marked by rusty dashes. Hind wings rich 

 yellow with a narrow black transverse band in the middle, 

 and near the hind margin another, much broader, which 

 throws off black streaks along the nervures inwards, towards 

 the first band, and outwards, more broadly, to the hind 

 margin. Sexes similar. 



Under side deep rich ochreous yellow, having on both fore 

 and hind wings a rather narrow central black transverse 

 stripe, and towards the hind margin another of a more 

 dusky black, throwing off broad dusky rays towards the hind 

 mai'gin, or even clouding the large space of the outer half 

 of the fore wings with smoky-black. Legs brownish-black 

 with the large tufts of scales yellow ; under parts of body 

 also yellow. 



Usually not variable except in a small degree in the 

 amount of pale mottling or clouding in the fore wings, but 

 when striking aberrations take place, they seem to be in con- 

 nection Avith the hind wings. Mr. S. J. Capper has a male 

 in which the hind wings are of a straw colour, and another 

 specimen in which the outer black band is obliterated, but 

 the inner is so suffused as to spread in a cloudy manner over 

 its space and towards the hind margin. One in Mr. Sydney 

 Webb's collection is devoid of the inner black band, and 

 another has it almost obsolete, while in a third the inter- 

 mediate space between the bands is filled up with smoky 

 colour, and the black of the outer band is suffused to the 

 hind margin. There is also considerable variation in the 

 width of the black bands. 



Kather unreliable in times of appearance, usually either 

 emerging in September or October, and, probably, hyber- 

 nating; or else lying in pupa through the winter and
