76 LEPIDOPTERA. 



this is the Nemeohius lucina, the male of wliich 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 Lyccenidce 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, Thecla, 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 wnth 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." In the genus Thecla the hind-wings have short 

 tails — a distinguishing mark, with one exception, viz., 

 the Green Hair Streak {Thecla rubi), so called from tlie 

 colour of the under surface of the wings. The tails here 

 are absent, or barely distinguishable. In Chryso])Jianus, 

 the fore-wings are coppery-red, with dark hind margin, 

 and often a black spot or two near the middle ; only one 

 species, I believe, now represents this genus, viz., the small 

 Co])per {C. jyhlwas), which may be known by its bright 

 copper-red fore-wings, with black spots, its hind-wings 

 very dark, wdth 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 disap])eared 

 altogether. The former, dispar (so-called from the dis-
