witli the margins dark ; the third striga is white, bordered by the strongly-dentated dark bar, which extends, of 

 a less intense colour, to the apex of the wing, the subapical striga being almost obsolete ; the cilia is spotted 

 with dusky shade ; the hind wings are pale, with the veins suffused with dusky shade, forming an interrupted 

 margin. Varieties occur in which the ordinary striga are much more distinct and brown, forming broad patches 

 on the wing ; the subapical striga very irregularly waved, and succeeded by a dusky cloud reaching to the tip 

 of the wing ; the inner margin at the base of the third striga being marked with a more distinct pale lunular 

 patch. Such a variety constitutes the A. Salicis, of Curtis. 



The caterjjillar is black, with fulvous hairs, and a stripe of red on each side above the feet. It feeds on 

 Menyanthos triplicata, as well as Myrica gale, and Sallow ; the moth appears in June, and seems in its range to 

 be a northern species. '

This common insect measures about 1| inch in the expanse of the fore wings, which are of a fulvous gray 

 colour, varied with brown patches and blackish markings; the two basal strigaj are broad and brown, with 

 strongly-dentated black edges on both sides ; the anterior stigma is round, with the centre slightly dusky, and

 strigce ; the outer stigma is large and nearly semicircular, brown in the middle, and with an edging of black and 

 brown, followed by a paler patch, which is terminated bj' the very strongly dentate duplicated third striga, the

 striga being pale but not distinct ; there is also a row of marginal black dots ; the hind wings are fulvous brown, 

 with a broad dusky border and a central spot.

This species is closely allied to A. Rumicis, measuring U inch in the expanse of the fore wings, which are 

 ashy brown coloured, with brown blotches ; the stigmata whitish coloured, preceded by the two ordinary striga.- ; 

 the space between the stigmata is pale ; the anterior stigma is round, and the outer one kidney-shaped, both 

 havino- a brown margin ; the third striga is terminated on the inner margin by a pale mark, and the subapical 

 striga is pale, the apex of the wing being dark ; the cilia is pale, spotted with brown ; the hind wings and 

 abdomen ashy coloured. 



The caterpillar is pale-coloured and hairy, with black dorsal spots and red lunules on each side above the 

 feet, except in the pedigerous segments, each of which has a white luuule. It feeds on several species of 

 Euphorbia, and the moth appears in May and August. It is a rare species, having occurred near London and 



in the New Forest.
