262 LEPIDOPTERA. 



colour of the head is reddish-brown and shining, the lobes 

 outlined on the face with blackish-brown, defining well the 

 triangular division and the upper lip, and below this the 

 mouth itself. The body is of a light fawn, inclining to flesh 

 colour ; a narrow scale-like plate of a glossy pale yellowish- 

 fawn colour is on the second segment, with an interval of the 

 paler skin toward the head ; a similar plate is on the anal 

 flap ; and a dorsal vessel of brownish-grey shows faintly 

 through the skin ; the rather small tubercular dots are fawn- 

 coloured, each with a short bristle ; sj)iracles black j anterior 

 legs pale fawn colour, the ventral and anal legs with a 

 fringe of dark brown hooks. 



The young larva at first is of a very pale greenish-drab 

 colour with blackish head and narrow blackish plate on the 

 second segment. After the first moult, when it has fairly

 of the body tinged with livid reddish -grey, the skin 

 rather shining and semi-transparent, through which a dark 

 internal vessel is visible ; the anterior legs reddish brown.

 larvas w^ere hatched on the ninth and tenth of July. While 

 they had a couple of flowers, with stems and leaves, of Silene 

 rivCtritima only, they were at first rather restless, but after a 

 few hours one or two settled down upon the leaves near their 

 extremities, where they ate little sinuous channels in the fleshy 

 substance, others chose the axils and nodes of the stems, 

 tunnelling into them and round which little lumps of frass 

 soon gathered. On inspecting the two Silene flowers the 

 male flower appeared not to have been touched, nor apparently 

 the female flower, but on pulling open the calyx I saw a little
