LARENTID-H—EUBOLIA. ^^ 



but very rare variation of a more striking character — Mr. 

 Robert Adkin possesses a magnificent specimen in which 

 the ground colour is slate-black, the basal blotch and the 

 narrow central band being the only portions of its fore wings 

 remaining grey ; it was taken at Box Hill, Surrey ; another,, 

 also from the South of England, in Mr. H. J. Turner's col- 

 lection, has the central band very dark, the ground colour 

 being almost white; and others are on record having the 

 ground colour quite white, — in one case the central band also 

 extremely pale. 



On the wing from the end of June to August, in a single 

 generation. 



Larva stout, rather flattened, bristly, the sides puckered ;. 

 head small, rather squared in front, brownish ochreous ;. 

 body putty-coloured or dull whitish-ochreous, sometimes 

 with a pinkish or yellowish tinge ; dorsal and subdorsal 

 lines grey, distinct ; between them is a very fine grey line,, 

 and below the subdorsal are two lines, side by side and 

 almost confluent ; usual raised dots and spiracles black ;. 

 undersurface having two conspicuous stripes, which are dark 

 grey in the middle of each segment and pale at the incisions, 

 thus seeming to be a series of pairs of dark grey dashes ;. 

 these stripes have an outside accompanying pale yellow or 

 pale brown stripe, paler than the ground colour. (Chas. 

 Fenu.) Varieties figured by Mr. "W. Buckler have the dorsal 

 region slate-grey or almost greenish-slate ; and the under- 

 surface, with a broad spiracular stripe, pale creamy-buff or 

 pinkish-white.
