TRIFIDJE. 361 



shade, which touches the reniform stigma as it passes to the 

 costa, and occupies a rather unusual position ; second line 

 tawny, more slender, but obli{(ue and almost parallel with 

 the central shade ; subterminal line hardly perceptible, a 

 mere faint series of whitish-yellow clouds between the 

 nervures; orbicular stigma large, round, only represented 

 by its rust-red margin ; reniform stigma moderately large, 

 rather constricted in the middle, having a slender similar 

 edging and a faint reddish internal cloud ; nervures all 

 sharply rust-red, giving the wing a rather reticulated aspect ; 

 cilia yellow dusted with tawny. Hind wings rather small, 

 rounded behind, yellowish-white ; cilia similar, faintly tinged 

 with red. Female hardly differing in any respect, except 

 that the antennae are threadlike, the body stouter, and the 

 anal tuft small and pointed. 



Underside of the fore wings straw-colour ; a rusty-looking 

 streak occupies the position of the reniform stigma, and 

 beyond it is a similarly coloured slender commencement of 

 a transverse stripe from the costa. Hind wings also straw 

 colour ; central spot small, pale rust-red ; beyond it is a 

 similar, slender, curved, transverse stripe reaching half-way 

 across the wing. Body, legs, and leg-tufts yellow. 



Rather variable in the tone of ground colour — from pale 

 yellow to rich ochreous or reddish-ochreous — less so in the 

 distinctness of the markings, though the central shade is 

 sometimes very strongly marked, and when this occurs in 

 a pale yellow example' it becomes a conspicuous oblique bar. 

 In rare instances the hind marginal region from the second 

 line is dusted or clouded with pale purple. 



On the wing in August and September. 



Larva tolerably plump, cylindrical, but tapering a very little 

 towards the head, which is smaller than the second segment ; 

 smooth and shining, it has the lobes globular but the face 

 rather flattened, pale brown \ mouth dark sienna-brown ; 

 skin of the body soft and smooth ; segmental divisions
