56 LEPIDOPTERA. 



so in the middle, edged on the inner side by an irregular 

 indented brownish line extending from the apex to the anal 

 angle. Across the middle of the wing are, sometimes visible, 

 two oblique, parallel, faintly brownish shades indicating 

 an oblique central transverse band. Cilia pink shaded with 

 brown at the nervures. The base of the dorsal margin is 

 tufted with long white scales. Hind wings black at the 

 base shading off to dull yellow in the middle of the wing, and 

 sometimes to blackish brown at the apex. Along the hind 

 margin is a broad purplish -pink stripe tapering off to a 

 point at the anal angle. Cilia white, interrupted with 

 purplish-red at the nervures. Sexes similar. 



Underside more brilliantly coloured than the upper. Fore 

 wings purplish-red along the costal and hind margins, blackish 

 from the base to the middle, the remainder light ochreous. 

 Hind wings ochreous, with the base and margins purple-red 

 and the cilia white. Under surface of head, thorax, abdomen, 

 and leg tufts, bright rosy red ; legs white. 



Variable in the tone of yellowish brown in the middle area 

 of the fore wings, and also in the depth of the rosy and 

 purplish-red of the margins. One taken in Perthshire by 

 the late Sir Thomas Moncrieffe has the rosy and purplish 

 colouring replaced by yellow and yellowish -grey, and the 

 body and thorax grey. One reared in London by Mr. W. H. 

 Tugwell has the fore wings olive-green, with the costal margin 

 rosy, and a faint shade of grey on the dorsal margin ; hind 

 wings greenish, with faint grey-brown shades along the 

 dorsal margin. 



On the wing in May and June, extending into July in its 

 more northern and north-western range. 



Larva over two inches in length ; smooth and plump, 

 rounded but thickest in the fifth and sixth segments, 

 tapering rapidly to the head, which is very small. When 

 this with the following segments is retracted it gives the 

 front part of the body a curious puffed appearance. The
