Antennae griseous, with a yellow shaft : thorax yellowish : abdomen luteous : 

 anterior wings ochraceous or pale straw tolour^ with two luteous or castaneous 

 strigffi frequently united, the basal one generally incurved towards the base 

 of the wing, as in the accompanying figure, and sometimes the two forming 

 a bar across the wings ; towards the base are usually one or two castaneous 

 or fawn-coloured clouds, and between the outer striga and the hinder margin 

 is an obscure irregular- waved streak of the same colour : posterior wings fawn- 

 coloured, with lutescent ciHa, and an obscure pale streak. Female larger and 

 stouter, dull chestnut-brown, with two obUque luteous or straw-coloured 

 striga?. 



Scarcely two specimens of this inconstant species are found precisely similar, 

 they vary so considerably. 



Caterpillar bluish, with irregular red and black streaks above, and red lateral 

 lines ; the hirsuties pale castaneous : it feeds on various plants, particularly 

 sea wormw^ood (Ai^temisia maritimci), also on birch, plantain, carrot, and 

 various Euphorbia : it prepares to undergo its change in the beginning of July, 

 and in August the imago appears : the pupa is dark coloured. 



This is apparently a maritime species, at least in Britain ; but not 

 strictly local, having- been captured in the Isle of Sheppey, and on 

 the coasts of Essex, Kent, and Devonshire : specimens are contained 

 in the cabinets of the British Museum, of Messrs. Haworth, Swain- 

 son, Vigors, in my own, &c. " Mouth of the Exe." — Dr. Leach.

A most variable insect, and considerably resembling the foregoing : the male 

 usually has the antenna?, thorax, and abdomen of a rusty fox-colour; the 

 anterior wings the same, with two yellowish oblique strigae, the space between 

 deepest, the cilia a little spotted with yellowish ; posterior wings usually im- 

 maculate ochraceous-red, with the cilia darker : the female pale ochraceous, 

 with a broad oblique central fascia on the anterior wings, margined with pale- 

 yeUowish ; the posterior wings rather darker, with a transverse dusky streak ; 

 cilia of all the wings spotted with ochraceous and fox-colour. 



Var. j3. Male of a bright ochraceous yellow, with two slender oblique fawn- 

 coloured strigae on the anterior wings, the cilia of all spotted with dusky and 

 ochraceous. 



Var. y. Both sexes with the thorax and base of the anterior wings ochraceous, 

 the latter followed by a broad fawn-coloured band, margined externally with 

 yellowish, the hinder margin rusty fox-colour. 



Var. ?. Both sexes of a deep uniform rusty fox-cclour, with two pale indistinct 

 ochraceous oblique streaks on the anterior wings.
