margin is broad rusty brown, with two white 

 spots. The nervures are dark brown, with 

 whitish spots and indistinct transverse Hnes. 

 The hind margin is Hght, and the submarginal 

 line dark brown. The projection on nervure 

 4 is larger than the others. The fringes are 

 chequered, and the scaly projection is dark 

 brown. The hind wings are violet-grey, with 

 a transverse line posteriorly, a dark anal 

 angle, and chequered fringes. The tliorax is 

 rusty brown, with a pale hind margin and 

 pale-bordered tegulas. The abdomen is dark 

 rusty brown. The moth is w-idely distributed 

 in Central Europe, appearing about the end 

 of April or beginning of May ; it is, however, 

 scarce. It may be found either sitting at the 

 foot of birch trees, or may be obtained by 

 beating. The larva is yellowish green, with 

 a dark green dorsal longitudinal stripe, and 

 a light j-ellow lateral stripe, which encloses 

 the black red-ringed spiracles. The last seg- 

 ment but one has two small spines. It lives 

 on birch in June and July. 



L. camelina, Linn. The Coxcomb Pro- 

 minent. PL XXII. fig. g. is common in most 

 parts of Europe from April to July or even 

 later. The larva is green, sometimes reddish, 

 whitish on the back, with a pale yellow lateral 

 line spotted with red, and two red spines on 

 the last segment but one. It feeds from June 

 to October om lime, birch, poplar, willow, 

 beech, aspen, etc. The pupa is dark brown, 

 with a terminal spine. It spins a slight cocoon 

 on the surface of the ground, and remains in 

 pupa till May. Var. giraffina, Hiibn. is 

 much darker. It is a rare form. 



L. cucullina, W. V. Fore wings ochre- 

 yellow, witli slender dark zigzag lines. The 

 inner margin and apex are rusty brown, the 

 hind margin white, with the portions of ner- 

 vures 4 and 6 enclosed in it intense black. 

 The projection on nervure 4 is larger tlian 

 in the other species. The fringes are chequered. 

 The hind wings are yellowish grey, with a 

 dark spot at the anal angle, divided by a 

 yellow streak, a yellowish subterminal line, 

 and indistinctly chequered fringes. The thorax 

 is rust-coloured, with a thick tuft of hair. 

 The abdomen is yellow. The moth, which 

 appears in May and June, is widely distributed 

 in Central Europe, but is not common. The 



larva is green at iirst, afterwards pale red, 

 with a dark green or dark brown cervical spot, 

 a red dorsal line, two small humps on each 

 of the segments near the middle, and a larger 

 one on the twelfth segment. It lives on maple 

 (Acer campestre and pseudoplatanus) and also on 

 Sorbiis terminal is. 



Genus Pterostoma, Germ. 



The palpi are very prominent, obliquely 

 raised and flattened, with long scales on both 

 surfaces. The fore wings have pointed tips 

 and twelve nervures. Nervures 7 and 8 rise 

 from the tip of the small appendicular cell, 

 g and 10 from S. The hind margin is uni- 

 formly dentated; the inner margin has a small 

 scaly projection in front of the middle, and a 

 small one in front of the hinder angle. The 

 antennse are bipectinated in both sexes, the 

 pectinations being smaller in the female. The 

 thorax has three parallel crests. The abdomen 

 is rounded, with a bifid anal tuft. The hind 

 tibia? have two pairs of long spines. 



P. palpina, Linn. The Pale Prominent. 

 Fore wings uniformly dentated, pale ochre- 

 yellow varied with light grey, and with the 

 nervures blackish in parts. There are two 

 indistinct deeply dentated transverse lines, a 

 dark shadow in the centre, and a row of dark 

 streaks. Behind the posterior transverse line 

 is a row of double dots on the nervures, and 

 between these and the dark submarginal line, 

 which is bordered with lighter, is a row of 

 small dots. The hind wings are brownish 

 grey, darker towards the hind margins, and 

 on the nervures with a zigzag transverse line 

 and whitish fringes. The antenna? are bipecti- 

 nated, the palpi very prominent, the thorax 

 with long hair and a comb. The male has a 

 bifid anal tuft. The moth appears from May 

 to June, and is common throughout Europe. 

 The larva is slender, granulated, flattened, 

 bluish green, with yellow longitudinal lines on 

 the sides. It lives late in the Autumn on 

 poplar, willow, and lime. The pupa is reddish 

 brown, and the cocoon is formed on the ground. 



Genus Drynobia, Dup. 



Antennae bipectinated in the males to the 

 tip, slightly dentated in the females. Ocelli 

 absent. The fore wings are acutely angulated.
