dentate, but without any tail. The under side is hrigdit green, the 
hind wings having a row of white spots. PI. XVIII., 3. 
Times of Appeaeance. — April, May, and August. 
Habitat. — Europe, Western Asia, and North Africa. (The 
North- American T. Bumetorim, Boisd., seems to be a variety of 
this species.) In Great Britain it is somewhat local, but common 
where it occurs, and of wide distribution ; it frequents woods and 
heaths. 
Lakva. — Shaped as in the other species, of a green colour, 
with lateral yellowish white stripes and oblique yellow lines, and a 
whitish dorsal streak. 
The Pupa is dark brown, without angles, with a silken belt 
attaching it by the middle, and with an anal attachment. Mr. 
Joseph Greene mentions that he has found this pupa under moss 
on an old tree-trunk. 
The larva feeds on the flower-buds of the bramble and on 
various Papilionaceous plants. The eggs are laid early in June ; 
the larva is full grown by the beginning of July. 
Theda Ruhi is a double-brooded insect in the more southern 
parts of its area of distrihution ; it is, I believe, only single-brooded 
in the north, as in Scotland, Scandinavia, North-Western Asia, &c.

The eyes in this genus are not hairy, as in Theda. The hind 
margins of the hind wings are not scalloped near the anal angle, 
and the under side does not exhibit streaks of light colour, but has 
rows of black spots along the hind margins. 
This genus contains but one species, unless we include Lyccena 
Ledereri of Herrich-Schaffer, which has tailed hind wings.
