BRITISH AXD EUROPEAX BUTTERFLIES AXD MOTHS. 



and have twelve nervures, of which 5 and 6 

 rise together, 7 from 5,. 8 from 7, and g and 

 10 from 8. There is no appendicular cell. 

 The inner margin has a large scaly projection. 

 The hind winr;s have eight nervures. The 

 thorax has a tuft of hair between the tegulae, 

 and the hind tibias have two pairs of spurs 

 The larvae are smooth. 



D. velitaris, Knoch. Fore wings greyish 

 brown, yellow at the base, with two white 

 transverse lines, bordered on both sides with 

 dark brown, of which the anterior is angularly 

 curved, and the hinder one slightly bent. There 

 is an indistinct yellow lunule in the centre. 

 The apex is divided by a line, which is indis- 

 tinct externally. The scaly prominence is 

 large, brown on the inner margin. The hind 

 wings are brownish grey, with an indistinct 

 transverse line, edged with darker below. The 

 antennae are yellow, and the collar and tegulae 

 brown, varied with light grey and bordered 

 with dark brown. The abdomen is greyish 

 yellow. The moth appears early in June, and 

 is local in oak-woods in Central Europe, except 

 Britain. The larva is yellowish green, with 

 bluish green head and sides. It has several 

 longitudinal streaks, and a deep red longitudinal 

 stripe, bordered below with white above the 

 legs. It lives on oak in July and August. 

 The pupa is brown, with a spiny projection at 

 the end. 



D. melagona, Scriba. is very like the last 

 species, but the tips of the wings are brown, 

 with black spots on the costa as far as the 

 hinder transverse stripe. The scah' projection 

 on the inner margin is black. The hind wings 

 are brownish grey. The moth is found in 

 Central Europe, but is rather scarce. The 

 caterpillar is bluish green, with four white 

 longitudinal stripes on the back, and a deep 

 red one, bordered with black and white, above 

 the legs. It lives on oak and beech in July 

 and August. 



Genus Gluphisia, Steph. 



Wings rounded, the fore wings with twelve 

 nervures. Ner\urc 1 1 rises from the subcostal 

 nervure, 7 from 6, 8 from 7, and 9 (which is 

 the shortest) and 10 from 8. There is no 

 appendicular cell, and no scaly projection. The 

 hind wings are small, with eight nervures. 



Xervure 5 is slender. The antennae are bi- 

 pectinated in both sexes. The legs are covered 

 with long hair. 



G. crenata, Esp. The Dusky Marbled 

 Brown. Fore wings brown and grey, with a 

 short dark transverse stripe behind the base, 

 and two others, with light margins, across the 

 middle. Between these is a lighter space, 

 with a faint yellow central lunule. There is 

 a pale subterminal line, darkly shaded. The 

 fringes are light grey, darker on the nervures. 

 The hind wdngs are rather paler, with a dark 

 blotch at the anal angle. The antennae are 

 rust -coloured, the thorax greyish brown, and 

 the abdomen greyish yellow. The moth appears 

 in May and June in Central Europe, but is 

 scarce and local. Epping is almost the only 

 British locality. The larva is green, with a 

 whitish dorsal stripe, bordered with yellowish, 

 and containing a white-centred dark red spot on 

 the third, fourth, sixth, and twelfth segments. 

 It lives on poplar in August, between leaves, 

 which it spins together. The pupa is black, 

 short, and obtuse at both ends. The cocoon is 

 formed on the ground. 



Genus Ptilophora, Steph. 



Antennas nearly half as long as- the costa 

 of the fore wings, very deeply pectinated as 

 far as the tip in the males, short and finely 

 ciliated in the females. Palpi very small. No 

 ocelli. Fore wings with twelve nervures. Ner- 

 vure 7 rises from 6, 8 and g by a common stalk 

 from 7, and 10 and 11 together from the small 

 appendicular cell. The inner margin is without 

 a scaly projection. The hind wings have eight 

 nervures, 6 and 7 rising from a long common 

 stalk. Nervure 5 is verj- slender in all the 

 wings. The body is not thick, but is clothed 

 with long, projecting hair. 



P. plumigera, W. \'. The Plumed Pro- 

 minent. The wings are thinly clothed with 

 scales. The fore wings are rusty yellow or 

 rusty red, with pale yellow transverse lines 

 beyond the centre, and long hairs on the 

 inner margin. The nervures are black. The 

 hind wings are paler, sometimes with indistinct 

 transverse lines. The antenna: are rusty brown ; 

 the thorax and abdomen rusty red. This 

 species is found in woods in Central Europe 

 in October and November. It is rare in this
