LEPIDOPTERA. 
this is the Nemeobius lucina , the male of which has 
only four developed feet, as was said above. It occurs 
in open glades in the South of England in woods in June 
and August. The larva, which is of a wood-louse form, 
feeds on the primrose. 
The family of Lyccenidtt contains the little Blue but¬ 
terflies so common in meadows, lanes, gardens, heathy 
downs, &c.; the Hair-streaks, brown and orange, or 
purple, and the Coppers, belonging to these three genera 
respectively, Polyommatus , Theda , and Chrysophanus. 
Most of the species are rather small in size, and fly low 
near the ground in a short jerky manner. The blues vary 
in colour, some females are brown, or purplish-brown; 
some are brown w'ith orange spots ; some are brown in 
both sexes. From the presence of a number of small 
eye-like spots on the under surface of the wings, this 
genus has received the name of Polyommatus, “ many¬ 
eyed. 55 In the genus Tlieda the hind-wings have short 
tails—a distinguishing mark, with one exception, viz., 
the Green Hair Streak ( Theda rubi ), so called from the 
colour of the under surface of the wings. The tails here 
are absent, or barely distinguishable. In Chrysophanus , 
the fore-wings are coppery-red, with dark hind margin, 
and often a black spot or tw’o near the middle ; only one 
species, I believe, now represents this genus, viz., the small 
Copper (C. phlccas ), which may be known by its bright 
copper-red fore-wings, with black spots, its hind-wings 
very dark, with copper-red margin. It is common 
everywhere. Two other species, the Large Copper (C 
dispar ), and the C. Chryseis , formerly occasionally seen 
in some parts of England, appear to have disappeared 
altogether. The former, dispar (so-called from the dis-
