234 LEPID OP TERA . 



costal half of the fore wings, a black spot on the costa, another 

 under the reniform stigma, and the nervures grey ; nervures of 

 the hind wings also greyish, and upon them a series of black 

 dashes indicating a central transverse stripe ; central spot 

 grey, body and legs whitish. 



Usually very constant in colour and markings, but there is 

 occasional variation in the intensity of the dark colouring of 

 the forewings and in the size and distinctness of the large 

 ovate pale blotch, which even in rare instances is no paler 

 than the rest of the wing. In the collection of the late Mr. 

 Bond is a specimen of a unicolorous black-grey. The pretty 

 pinkish or lilac tinge which is sometimes observable, rather 

 indicates extreme freshness than any variation, and un- 

 fortunately very soon fades. 



On the wing from the end of May to August in a single 

 generation. So far as I know there is but a single record in 

 this country of the appearance of specimens of a second 

 emergence in the year. This occurred at the end of July 

 1858. 



Larva stout, rounded and rather flattened ; long whitish 

 hairs on the sides and on the second and anal segments ; head 

 large, rounded, slightly bifid, not highly polished. Greyish- 

 ochreous with three converging waved bands of collected 

 black dots on the back ; spiracular line, and a line above the 

 black spiracles, waved and composed of an accumulation of 

 dark grey dots ; dorsal spots from the third to twelfth 

 segments raised and of a reddish-orange colour ; remaining 

 dots also raised, but of the ground colour ; on the eleventh 

 segment is a large half-oval prominent dorsal patch of a dull 

 ochreous or greyish-ochreous edged with black, the rounded 

 portion in front. Head pale bluish-grey, the lobes margined 

 internally and externally with black, or else black with a 

 broad pale greyish stripe down each lobe ; mouth black ; legs 

 and prolegs deep yellow ; under-surface very pale grey, the 

 centre greenish. (C. Fenn.)
