170 HAUSTELLATA. — LEPIDOPTERA. 



Caterpillar dirty green, with a yellowish-white lateral line edged with brownish : 

 it feeds on the] Astragalus Onobrychis, &c. : — the imago is formed, towards the 

 end of May. 



A rare species ; two or three specimens have been taken between 

 Birch-wood and Bexley ; and I possess a pair captured in Bulstrode 

 Park by the late Duchess of Portland. 



B. Eyes naked. (Antennae simple in both sexes.) 



Sp. 2. rhizoUtha? Alis anticis canis, nebulosis, lineold baseos supernc bifidd 

 serieque punctorum nigrorum ad marginem posticum. (Exp. alar. 1 unc. 6 — 8 

 hn.) 



No. rhizolitha. Hilbner? — Xy. Lambda.? Steph. Catal. part ii. p. 78. No. 6177. 



Head and thorax hoary, the latter with a black arch, edged posteriorly with 

 white, in front : anterior wings also hoary, with darker clouds, a black ab- 

 breviated lineola at the base, terminating in two or three twigs, another slightly 

 curved forming an edge to the posterior stigma, between which and the inner 

 margin of the wing is a third united to a black hook in the place of the teUform 

 stigma of the Agrotes : on the hinder margin is a row of minute black dots ; 

 the ordinary strigae are more or less apparent, but suddenly bent near the 

 costa, and the stigmata distinct but obsolete : the posterior wings are deep 

 fuscous with the cilia paler. 



In some specimens the markings are nearly obliterated, and the wings scarcely 

 clouded. 



Caterpillar downy, green, spotted with white, with a bluish dorsal line: it feeds 

 on the oak : — the imago appears in the autumn. 



Not very common: I have once or twice found the insect at 

 Hertford and at Coombe-wood, and in other parts of the metro- 

 politan district. " Netley, Salop." — Rev. F. W. Hope. " Epping."

Somewhat reserabUng the last, but rather of a different colour : head and thorax 

 dusky-ash ; anterior wings of a deep ash-gray, with a dusky spot at the border 

 and several deeper ash-coloured strigse, with an obsolete whitish central spot, 

 and a pale striga near the hinder margin ; the cilia with fuscous stripes : 

 posterior wings whitish with the nervures dusky or fuscous. 



Caterpillar green, with whitish spots and lateral line: — the imago appears in the
