BRITISH AXD EUROPEAN BUTTERFLIES AXD MOTHS. 



The larva is long, shining pale green, with 

 darker sides, with two yellow dorsal lines 

 and another above the legs. It lives on oak 

 in June and July. 



N. querna, W. V. Fore wings dark grey, 

 varied with reddish, with a short black trans- 

 verse line at the base, two white transverse 

 lines, bounded with black, a white central band, 

 edged on the inner side with light grey, a 

 w'hite central lunule between them, and a 

 reddish grey subterminal line in front of the 

 hind margins. The fringes are chequered with 

 lighter and darker. The hind wings are whitish 

 in the male, light grey in the female, with the 

 nervures here and there dusted with darker. 

 The antennas are rust-coloured. The head 

 and thorax are ashy grey, varied with w"hitish, 

 and the 'tegulae are edged with grey at the 

 tips. The abdomen is ashy grey. The moth 

 frequents oak-woods in Central Europe, but 

 is not found in the British Isles. The larva 

 is dark green, with two yellow dorsal stripes, 

 and a yellow stripe on each side above the 

 spiracles, as well as a prominence on the last 

 segment but one. It lives on oak in July. The 

 pupa is black, with a terminal spine. 



N. dodonaea, \\'. V. The Marbled Brown 

 varies much in colour and markings. It is 

 distinguished from the last two species by the 

 absence of either a black or a white central 

 lunule on the fore wings. The fore wings are 

 marbled with grey or brownish grey, with a 

 short dark transverse line and two complete 

 white ones at the base, the inner of which is 

 edged on both sides, the outer on its outer 

 side only, with darker. The space between 

 them is light grey on the outer half. There 

 is no central lunule, and the subterminal line 

 is indistinct. On the costa near the tip is a 

 dark brown spot. The hind wings are pale 

 greyish brown, with a white transverse band. 

 The antennae are brown, the thorax light grey, 

 and the abdomen yellowdsh brown. It appears 

 in April and May, and is not uncommon in 

 oak-woods. It is chiefly found in Western 

 Europe. The larva is shining bluish green, 

 light above, dark at the sides, with a yellow 

 dorsal stripe, and an orange stripe above the 

 legs. It feeds on oak in July and August. 

 The pupa is brown, with a terminal spine. 



N. bicolora, W. \'. The White Prominent. 



PI. XXII. fig. S. is found in May and June 

 in open birch-woods in Xorthern and Central 

 Europe. The larva is shining green, with a 

 white dorsal stripe, yellow longitudinal line, 

 and a broader orange longitudinal stripe above 

 the legs. It feeds on birch in July. The pupa 

 is dark brown, and is enclosed between leaves 

 and moss on the groimd. 



N. argentina, W. V. Fore wings pale 

 olive-brown, clouded with darker between the 

 nervures at the apex, with indistinct trans- 

 verse lines, which are only visible on the costa. 

 There is a faint subterminal line, composed 

 of small black spots, bordered on the inner 

 side with lighter, and a larger triangular and 

 smaller crescent-shaped silvery spot surrounded 

 by brownish red and orange spots. The scaly 

 jirojection on the inner margin is orange- 

 coloured, and the inner angle is reddish brown. 

 The hind margin has pale nervures, and is 

 deeply dentated on the free border. The hind 

 wings are yellowish grey, the thorax reddish 

 brown, and the abdomen paler, w'ith a bifid 

 reddish brown anal tuft. The moth is found 

 chiefly in the southern parts of Central Europe, 

 and is fairly common in some seasons. It fre- 

 quents oak-woods, and appears early in June. 

 The caterpillar is slender, smooth and reddish 

 brown, with a row of yellow spots on the sides, 

 two conical projections on the fifth segment, a 

 transverse pad on the eleventh, and several 

 small elevations on the twelfth segment. It 

 lives on oak in July and August. Some of 

 the chrysalids produce moths in the same year. 

 The pupa is shining dark brown, and is hidden 

 under moss. 



Genus Lophopteryx, Steph. 



Fore wings pointed, deeply dentated, with 

 generally a rather large projection on nervure 

 4. It has twelve nervures and an appendicular 

 cell. The inner margin has a large scaly 

 projection. The hind wings are broad and 

 rounded. The thorax has a large erect tuft 

 of hair between the tegulae. The antennae in 

 the males have only a small leaf-like projection 

 on each joint beneath; in the female they are 

 slightly serrated. The ocelli are absent. The 

 hind tibiae have four spurs. 



L. carmelita, Esp. The Scarce Prominent. 

 The fore wings are violet-grey. The costal
