90 BRITISH BUTTERFLIES 
wings are ashy, with a white streak which is slightly angulated at the anal angle. Towards the posterior 
margin are several fulvous lunules marked with black, and a large bluish spot at the anal angle, with a terminal 
black spot. 
The caterpillar is green, with dorsal lines formed of yellow spots, and with a black head, when more mature 
it becomes reddish. The chrysalis is pilose, brown above, and ashy beneath. This description, which is 
translated from the Fabrician character, together with our figures taken from German specimens of T. Spini, 
will enable any one to determine the species in case it should be captured in this country which is very probable.

The expansion of the wings of this species is rather greater than that of Th. Spini. The upper side of the 
wings in the male is of a blackish brown colour with a greenish tinge, whilst the female has a large orange patch 
on the disk of the anterior pair of wings beyond the middle. In both sexes the anal angle is marked with a 
reddish spot. The under side is brown grey, with a very slender somewhat waved white streak, edged internally 
with black, extending across all the wings and forming an obtuse W near the anal angle. The hind wings are 
also ornamented with a row of orange crescents between the white streak and the margin of the wing, bordered 
with black, the anal angle itself being also orange ; the tails and base of the ciliz of the hind wing being black, 
edged internally with white. 
The caterpillar is green, varied with slender oblique lateral lines and dots, and a dark purple line down the 
side. It feeds upon the evergreen oak. 
I have introduced this species on the authority of a specimen in the collection of Mr. Meynell, stated to have 
been taken in Yorkshire. From later information, however, given to me by Mr. Stephens, there is perhaps 
reason to doubt the fact of the capture of the specimen in this country, it having been purchased from a dealer 
in London who is reputed not to be sufficiently precise in the localities of his specimens of rare Lepidoptera, and 
who moreover deals in exotic and European as well as British insects. It is proper to mention the circumstance, 
although there seems no reason why the species should not be a native of this country, the Quercus Ilex, or 
Common Evergreen Oak, which is a native of the south of Europe, having been extensively cultivated in Britain 
from a very remote period.

This species, which from the nature of the food of its larva is more frequently observed flying nearer the 
ground than its congeners, varies in the expanse of its wings from one inch to an inch and a third ; on the upper 
side the wings are of a uniform obscure brown colour, with a slight silky gloss, especially in the male, which has
