52 HAUSTELLATA. — LEPIDOPTERA. 



an interrupted dusky line ; cilia fuscescent : posterior wings whitish, with 

 a striga behind the middle, and the posterior margin dusky; cilia pale 

 ochraceous. 

 Caterpillar yellowish-white, with dusky-brown head : it feeds on the birch: — 

 the imago is found about the middle of June, in woody places. 



This handsome species is far from common ; it occurs in Darenth 

 and Birch-woods, and very rarely at Coombe : in the former locality 

 I have captured several examples at different periods. 



Sp. 2. duplaris. Alls anticis cinereis,fa.icid fuscescente in medio, in qua punctis 



duobus nigris. (Exp. alar. 1 unc. 3 — 6 lin.) 

 Ph. Ti. duplaris. Linne. — Ce. duplaris. Steph. Catal. part ii. p. 95. No. 6301. 



Antennae, head and thorax ashy-griseous, the latter margined with cinereous : 

 anterior wings fuscous-ash, with the base rather paler, and having a short 

 curved fuscous striga, and a second, edged with whitish, on the outer edge of 

 the pale blotch ; this is followed, as in the last species, by a broad fuscescent 

 fascia, in which are some obscure transverse slightly waved strigas, and on its 

 exterior edge, in place of the posterior stigma are two distinct black dots, 

 beyond which is a pale hoary-cinereous fascia, terminated by a dentate 

 fuscous striga, from whence to the hinder margin is fuscous, with an undulated 

 whitish striga, posterior margin with a slender obscure interrupted fuscous 

 line ; cilia fuscous, with minute darker spots at the base : posterior wings 

 fuscous-ash, with an obscure paler striga behind the middle, and a dusky 

 central lunule. 



Very similar to the preceding, but smaller, and much darker and less glossy, 

 but distinguished at once by the geminated black spots on the anterior 

 wings. 



Caterpillar yellowish-green with a reddish dorsal line and minute white dots; 

 the head reddish-brown : — it feeds on the poplar : — the imago appears to- 

 wards the middle of June, and frequents woody places. 



Not very uncommon at Darenth-wood and near Ripley: it occurs 

 also in the New Forest, Devonshire, &c. " Epping, very common."

B. With the anterior wings broad, with distinct transverse fasciae ; body not very 

 stout ; palpi a little elongate, the second joint somewhat dilated, with rather 

 long scales. 



Sp. 3. diluta. Alls anticis cinereis, fasciis duahus rectis ferrugineis obsoletis, 

 strigfique pallidiori undatil. (Exp. alar. 1 unc. 3 — 6 lin.) 



No. diluta. Wien. T.— Ce. diluta. Steph. Catal. part ii. p. 95. No. 6302.— Half 

 Mourner. Harris, pi. 35. f. 6— S. 



Head and thorax cinereous, the latter with a transverse dusky streak in front ; 

 anterior wings cinereous, irregularly clouded with obsolete dusky spots ; with 

 two nearly straight transverse pale ferruginous fasciae, more or less distinct.
