willow, sloe, birch, rose, trefoil, &c. in May and June ; the imago is produced 

 in September or October. 



Not a common species; taken occasionally in woody situations, 

 and thick bushy hedges : I have found the larva at Darenth-vvood, 

 and captured the insect at Hertford. " Epping." — M?: H. Double-

Head, thorax, and anterior wings nearly concolorous, yellowish-brown or bright 

 ferruginous ; the latter with the ordinary strigse in general very tlistinct, and 

 intersected with pale rufous or ferruginous nervures ; the stigmata generally 

 distinct, ashy-brown with pale edges ; the anterior one very variable in form, 

 in general linear, sometimes ovate, and mostly of a deeper colour than the 

 posterior, which is of a more elongate form than usual ; and between it and 

 the hinder margin is usually a striga of black dots; posterior wings deep 

 fuscous, with rufous cilia.

 wings very deep ferruginous, with two obsolete strigse of fuscous spots before 

 the stigmata, a third near the posterior one, then an obscure darker fascia, 

 and another in the margin. 



Var. y. Steph. Catal. I. c. — Anterior wings ferruginous, with the ordinary strigiE 

 very distinct, and several rows of dusky spots between the fifth and the pos- 

 terior margin. 



Var. §. Steph. Catal. I. c. — Anterior wings deep ferruginous, with a series of 

 black spots near the posterior margin, the rest of the wing immaculate. 



Var. £. Steph. Catal. I. c. — Anterior wings dull ferruginous, with two paler 

 strigae, the posterior margin deeply fuscescent, obsoletely intersected with 

 ferruginous nervures. 



Var. 9. Anterior wings pale hoary-ash, tinged with rufous : the ordinary strigae 

 pale fuscous, and the stigmata deep ashy-brown. 



To attempt the description of all the varieties of this truly protean insect, of 

 which those above described have hitherto been considered as distinct species 

 in this country, would be fruitless. I shall merely add, that I have reared 

 several of the varieties from similar larvae, and that all are found at the 

 same place and season. 



Caterpillar green, with a lateral whitish or rufescent streak and pale spots : it 

 feeds on the Centaurea Scabiosa and Ranunculus bulbosus : the imago appears 

 in September. 



An insect of moderate rarity, occurring chiefly at Darenth and 

 Birch woods.
