io8 European Butterflies and Moths, 



with yellowish-brown tufts of hair and longer black ones. It feeds on most trees and shrubs. 

 The male moth is figured at PI. 24, Fig. i. 



* 2. O. Antiqua (Linn.), {Vapourer Motli). — Fore-wings of the male brownish-rusty, with dark 

 transverse lines ; a round \\hitc spot near the hinder angle, and dark spotted fringes ; hind-wings 

 rust-colour. Expands from I to ij inches. Female yellowish-grey, with rudimentary wing.s, and 

 two rows of pectinations on the antennae. Abundant at the edges of woods, and flying about 

 bushes throughout Europe. It also occurs in Armenia and North Africa. The larva is ash-coloured, 

 striped with reddish-yellow and white ; the tufts are yellow or brown, and those on the 2nd and 

 I2th segments, as well as two horizontal tufts on each side of the 5th and 6th segments, are black, 

 with the ends of the hairs thicker. It feeds on all kinds of deciduous trees, and even on the laurel, 

 which is attacked by very few insects. The male, female, and larva are figured at PI. 24, Fig. 2, 

 a — c. (0. Aurolimbata, Gu6n., from Spain and the Pyrenees, is of the size and shape of /I ////(^wa:, 

 but is of a uniform dull brown, with yellowish fulvous fringes. The female is completely apterous, 

 with the head black and horny ; and the larva feeds on broom, &c. 0. Riipestris, Ramb., from 

 Corsica, more resembles Antiqua ; the wings are brownish-rusty, and the fore-wings have three 

 indistinct ashy transverse stripes, the last of which descends to the white spot at the hinder angle.) 



3. O. EriccB (Germ.). — Fore-wings of the male rusty-brown, paler towards the hind margin, with 

 an indistinct whitish spot near the hinder angle, and unspotted fringes ; hind-wings brownish ; 

 female pale grey, wingless, with the antennae not pectinated. The male expands i inch. Widely 

 distributed throughout Northern Germany and the adjacent parts of Russia, but exceedingly local, 

 and generally rare. The larva is saffron-yellow, with black longitudinal stripes ; the tufts are 

 whitish-yellow, and the longer ones black. There are also raised yellow warts on segments 10 

 and II. It lives on boggy heaths, feeding on Myrica Gale, Andromeda pallida, &c. 



4. O. Trigotcphvas (Boisd.). — Dark brown ; fore-wings with a very broad but rather ill-defined 

 undulating transverse fascia ; a triangular ashy spot in the middle, a roundish one at the tip, and a 

 white one near the anal angle ; hind-wings unicolorous. Female white, apterous. Inhabits South- 

 western Europe in June and July ; the larva lives on various trees and shrubs in May and June. 

 {0. Ramburii, Mab., is brown, the fore-wings spotted with darker, and with the usual white spot 

 near the hinder angle ; hind-wings paler towards the base. It inhabits Corsica in autumn, and 

 the larva feeds on a species of broom. 0. Ledereri, Mill., is a large dark brown species from Sicily, 

 more like a Geometra than a Boinbyx. It expands i^ inches. There are two transverse grey 

 lines on the fore-wings, indistinctly bordered with black ; the outermost is very much dentated. 

 The fringes are spotted with dirty white.) 



5. O. Dubia (Tausch.). — Brown ; fore-wings with two black transverse stripes near the base, a 

 spot in the middle, below the costa, and a spot or streak beyond. Sometimes the second and 

 fourth of these markings extend nearly to the inner margin, meeting so as to form a black U, 

 enclosing the subcostal spot. The fore-wings are more or less varied with tawny, and are 

 sometimes almost entirely tawny, the basal streak being obliterated. Hind-wings either brown, 

 tinged with tawny at the anal angle and inner margin, or tawny, with the costa and hind 

 margin varied with .brown or black. Expands about i inch. The female is apterous. It 

 inhabits the south of Spain and Russia, and Asia Minor. 



GENUS II. — PENTHOPHORA (GF.RM.). 



Body of the male slender, and the wings moderately broad and rounded ; the female with 

 rather thick bod>' and narrow wings ; the fore-wings are scarcely more than half as long as
