44 THE GENERA AND SPECIES OF BRITISH BUTTERFLIES. 
several localities in the North ; but is very rare in Scotland. It has been recently taken in 
great abundance at Brighton, Epping, Exeter, Tenterden, and other places. 
Thecla Rubi (the Green Hair-streak), This is the least Thecla-like of any of the British 
species, being nearly without the elongation of a portion of the hind wings, which is one of the 
chief characteristics of the genus. In other respects, however, especially in the Caterpillar and 
Chrysalis stages, it closely resembles its congeners. It is one of the earliest species, being often 
found in May. The male, the female, and a specimen showing the under side of the wings, are 
figured at Nos. 6, 7, and 8. 
The Caterpillar (No. 9) feeds on the common Bramble, and also on Papilionaceous, or Pea- 
flowered, plants. It may be found in May and June, and again in August. The autumnal 
brood remains in the Chrysalis state during the winter, Butterflies appearing in the following 
May. The perfect insects resulting from the spring brood of Caterpillars, appear about the 
beginning of August. 
It is very generally distributed, and rather common—being found in some abundance in 
most of the English counties, and in the south of Scotland, but rarely further North. 
Mr. Stephens describes a variety in which the white dots on the under side are much more 
conspicuous ; and also one in which the anterior wings of the female have a pale whitish spot 
near the centre of the anterior wings. It has been recently taken at Teignmouth in great 
numbers. 
The other species—Theela Spini and Thecla Llicis—were formerly considered British by some 
collectors, but they are both omitted in recent catalogues.
