88 HAUSTELLATA. — I.F.PIDOPTEKA. 



on Dover-cliffs, and on bramble blossoms, in rocky situations, in 

 North Wales : several specimens were taken in Kent during tlie 

 past season, I believe in the vicinity of Deal : it is said to have 

 occurred near Winchester in plenty ; and Lewin tells ns that it is 

 found on Marlborough-downs, Wilts, on hills near Bath, and near 

 Clifden, in Bucks; but the last locality probably belongs to Po. 

 Alcon, which may prove to be an extraordinary variety only of Po.

Wings above, in the male, resembling var. /3. of the preceding species ; beneath 

 brownish-ash, the anterior with ocellated black dots, as in the preceding, and 

 a series towards the hinder margin, which has not the lunulated spots, as in 

 Po. Arion : the posterior wings also bear ocelli, as in the last-named insect, 

 and a series behind, but the hinder margin is nearly immaculate. The female 

 is nearly all brown above, with some obsolete dots, but resembles the male 

 beneath. 



Of this insect I have seen but one specimen, which is in the rich 

 lepidopterous collection of Mr. Haworth : it was captured by the 

 late Mr. Jones, known by his paper on the neuration of the wings 

 of the Linna^an Papiliones, in Buckinghamshire, many years since.

Male above of a rich pale silvery-blue, with the hinder margin and nervures 

 black or dusky, with the cilia white, interrupted by dusky ; the posterior wings 

 with five sub-ocellated spots in the hinder margin : beneath the anterior wungs 

 are whitish, ocellated nearly as in Po. Arion, but usually with two or three 

 additional spots towards the base of the wing; and beyond the undulated band 

 of oceUi is an interrupted brown streak, between which and the hinder mar- 

 gin is a series of sub-oceUated round dots, with a whitish circle : the cilia 

 ■white, interrupted with brownish at the tip : posterior wings cinereous, green- 

 ish-blue at the base, with about twelve ocellated spots, four at the base, and 

 eight forming an angulated band behind the middle ; the pupils black with a 

 white iris ; in the centre of the wing, between the bands is a white sub- 

 triangular spot, which is sometimes immaculate, and sometimes bears a dusky 

 or black dot in its centre ; on the hinder margin is a series of ocellated black 

 spots, with a white iris, marked internally with orange, and tipped with a 

 black angulated line pointing inwards ; this series is connected by a pure 

 white oblong patch to the external ocellated band : cilia white. Female above
