112 HAUSTELLATA. — LEPIDOPTERA. 



beyond the costa of the anterior, as in many of the Bombycidse : the 

 serrated antennse of the males also serves to distinguish that sex 

 with facility from the other genera. 



Sp. 1. Ocellatus. AUs subangidatis, anticis ruhicundo, brunneo fuscoque varie- 

 s;atis, posticis roseis, ocello coeruleo. (Exp. alar. $ 2 unc. 9 lin. — 3 unc: 2-

Sph. Ocellata. Linne. — Don. viii. pi. 209. — Sm. Ocellatus. Steph. Catal. 



Anterior wings angulated, of a rosy-ash, with a clouded, oblique, central, in- 

 terrupted band, several undulated strigs, and the hinder margin irregularly 

 brown; a central discoidal pale sublunate transverse streak; and midway 

 between it and the hinder margin a blackish-brown spot, and frequently two 

 or three similar maculations at the anal angle ; posterior wings rosy at the 

 base, the anterior edge cinereous, with paler clouds, and the posterior rosy- 

 griseous ; towards the anal angle is a large ocellus, having the pupil of great 

 size, of a bluish-brown, the iris blue, and an outer circle of black, the latter 

 coloiir often reaching to the anal angle, which is generally dusky: fringe of 

 all the wings brown, edged with white near the anal angle of the posterior, 

 which have a sUght emargination : head and thorax pale cinereous, the latter 

 with a deep brown patch; abdomen dark immaculate cinereous. 



Caterpillar very rugose, of a beautiful green, with oblique white lateral stripes, 

 and whitish ocellated spots, the anterior legs and stigmata rosy: — it feeds 

 on the various species of willow {Salix), poplar {Populus), apple (^Pi/rus 

 Malus), and sloe (Prunus spinosd), and appears in the autumn, changing 

 in September to a brown pupa with a black back. 



The imago is produced towards the end of May, and is found in 

 tolerable plenty in several places near London, especially on Epping 

 Forest, near Wanstead, where there is a profusion of aspen trees, 

 and in the marshes about Limehouse, Bow, and Stratford ; also in 

 Battersea Fields ; at Hertford, Ripley, &c. " Not uncommon near 

 Spitchweek, Exeter, and near Ashburton, Devon." — Dr. Leach, 

 " In great abundance near York." — W, C. Hezvitson, Esq. — 

 " Near Carlisle." — T. C. Heysham, Esq. " Occasionally met with 

 at Bottisham and Cambridge, but not common." — Rev. L. Jenyns. 

 Harris mentions, in his Aurelian, that he once found a specimen of 

 this species in whose abdomen several specimens of a Dermestes 

 had taken up their abode while the insect was yet alive. 



Sp. 2. Popuh. AUs dentatis griseis fasciis ohscuriorihus, anticis puncto medio 

 alba, posticis basi ferrugineis. (Exp. alar. <J 3 unc. — 3 unc. 6 hn. : ? 3 unc.
