BOARMID.'E—ASPILATES. 45 



concoloi'ous. Antennae of the female simple, body much 

 stouter ; fore wings rather narrower, a little more dusted with 

 yellow-brown, and often with the oblique stripe less distinct ; 

 otherwise similar. 



Underside of the fore wings pale yellow with a large 

 smoky cloud from the base to the middle, and the oblique 

 stripe smoky-black ; dorsal region silky-white. Hind wings 

 pale yellow dusted with brown ; central spot brown, and 

 beyond it a short oblique partial yellow-brown stripe ; dorsal 

 margin yellowish-white. Body yellow; legs purplish- 

 brown. 



Slightly variable in the depth of the colour of the fore 

 wings and in the distinctness of the oblique stripe, and also 

 in the presence or absence of a faint stripe on the hind 

 wings. A male specimen in the collection of Mr. Sydney 

 Webb is devoid of the oblique stripe of the fore wings, 

 another has no discal spot; a female has the oblique stripe 

 most conspicuously darkened and spread outwardly so as to 

 extend almost along the hind margin, while others have the 

 brownish dusting very much intensified. 

 On the wing in July and August. 



Larva rather slender, cylindrical, stoutest at the tenth 

 segment, thence tapering almost imperceptibly to the head, 

 which is flattened and narrowed a little in front ; anal flap 

 ending in two short points, whilst from under it projects 

 a pair of longer and more slender points, slightly curved 

 inwards and projecting quite one-sixteenth of an inch ; skin 

 smooth but transversely wrinkled on the hinder part of each 

 segment and along the spiracles ; when handled it feels 

 tough and stiff. Ground colour pale greyish-ochreous, with 

 a pinkish tinge along the sides ; down the back is a broad 

 paler stripe having a rather dark brown line down its middle, 

 most distinct on the front segments, and edged with a fine 

 brown line; a broad pale greyish-buff subdorsal stripe, 

 beginning on the head and continued to the extremity of the
