The ground culour varies from dark brown to violet-grey, more or less tinged 

 with violet. The dorsal and sub-dorsal lines are pale violet-grey, only very rarely 

 blueish-whitc, in which case, however, this colour predominates in the narrower 

 central dorsal line. Anterior legs bright cinnamon-coloured, the same as the 

 spiracles ; prologs pale cinnamon-colonred. 



Eight days before pupation the larva appears with a broad gi'cy band along the 

 back, whicli is very distinct from the ground colour, but this vanishes again in two 

 or three days, so that the back then only looks a little paler ; the spiracular line 

 assumes a darker shade ; the dorsal lines become paler and unconnected ; the sub- 

 dorsal lines and generally also the non-central dorsal lines seem to consist of small 

 irregular spots, and assume a darker shade. 



Between the dorsal spots on segments four to six, there appears an oblique, dark 

 shade, which is wanting on the other segments, and the first of these is especially 

 conspicuous as a horse-shoe-shaped mark. Here and there the larva appears as 

 though dark shaded or violetish, especially the segments on the back, where the 

 shading from the distance shows itself acutely-angular. 



Some four days later, the ground colour is faintly violet, here and there shining 

 through greenish ; the violet colour being most distinct at the incisions of the 

 segments. The yellow spiracular line is shaded with dark above and below, the 

 shading most intense above and around the spiracles. The second segment and anal 

 prologs ferx'uginous ; the head dark chestnut-brown. The fine dorsal lines and the 

 sub-dorsal lines only faintly indicated as though formed of dot-like dusting. On the 

 anterior segments these lines, especially those on the back, still remain revj distinct : 

 the central one bluish-white, the lateral lines yellowish. The shade between the 

 dorsal spots on segments three to five is pale brown ; horse-shoe mark dark brown ; 

 anal segment violet-grey. 



Shortly before pupation the larva becomes violet-grey, finely sprinkled with 

 brown ; the spiracular line pale yellow, with faint shading, which has become more 

 concentrated round the spiracles. The dorsal spot shading is strongest on segment 

 three, fainter on segment four, and feeblest on segment five. The wedge-shaped 

 marks on the incisions of the segments violetish, most distinct from the fourth 

 and fifth. 



The imago escaped from the somewhat compressed pale brown pupa after an 

 interval of twenty-eight to thirty days. — Cael Beeg, Musco Publico, Buenos Ayrcs :

iVo?a albulalis, ^'c, in North Kent. — On Monday morning last, the 13th inst., I left 

 home for five days' collecting in North Kent, in company with the Rev. T. W. Daltry, 

 of Modeley. A day or two before, Mr. Daltry, who had been there the week previous, 

 had written me he had found out the locality for JS^ola albulalis, and to collect this 

 species was my principal inducement for going. Monday evening we went to the 

 marshes and iouudi Acidalia emutaria not nnco\x-iv:ior\ ; next morning we found an 

 abundance of Acidalia rusticata on two elm hedges ; the afternoon and evening we 

 spent in the albulalis locality, and took the species very freely ; "Wednesday and 

 Thursday evenings we had equal success, albulalis flying in abundance, indeed, at 

 cue time, standing in one spot, I took them as they flew past as fast as I coidd box 

 them. Friday evening we went again, but were astonished to find that not a speci-
