Orgyja. 107 



Andalusia in May. The larva has reddish hairs on the sides. {O. Hcuiigrmr, Grasl., from 

 the Pyrenees, appears to be only a northern variety in which the pectinations of the antennae 

 are shorter, and the wings of the female are rudimentary. The larva is black, with a whitish 

 line on the back, and an interrupted orange streak on the sides. It is full-grown in July and 

 August, and the moth, which flies by day, appears in May.) 



2. O. Parasita (Esp.). — Brownish-grey ; fore-wings of the male with two rows of long 

 black triangular spots ; hind-wings unspotted. Female with three rows of shorter and broader 

 spots on the fore-wings, and with black marginal spots on all the wings. The male expands 

 i-^ inches, and the female three-quarters of an inch. Inhabits the Valais and South-Eastcrn 

 Europe in March and April. The larva varies from yellowish to brown, with three light lines 

 on the back, and rust-coloured or brown hair. It feeds on nettles, &c., in May and June. 



3. O. Bcetica (Ramb.). — Antennae pectinated ; body very hairy ; fore-wings black, banded 

 and spotted with reddish-white ; hind-wings with a spot at the base and an angulated submar- 

 ginal band. The male flies by day, and the female has rudimentaiy wings. It inhabits Spain, 

 and appears in September and October. The larva is gregarious, and is extremely variable. 

 (In 0. Corsica, Ramb., which inhabits Corsica and Sardinia, the fore-wings of the male are 

 black, with yellowish-white bands and spots, and the hind-wings are fulvous, with the hind 

 margin spotted with black. In the female the rudimentary wings are ochreous, spotted with 

 brown. The larva feeds on grass, and the moth appears from March to May.) 



FAMILY III.— LIPARID^. 



Moths of moderate size, with stout hairy bodies; the abdomen is more slender in the male 

 than in the female. The tongue, palpi, and legs are short ; the femora are hairy. The 

 antennae are short, with long pectinations in the male ; in the female the pectinations are 

 shorter, or the antennae are simple. The hind-wings are broad and rounded, often reaching to 

 the tip of the abdomen. They are more slender than the fore-wings, and can be folded ; 

 ncrvule 5 rises near nervule 4, and is sometimes absent. The fore-wings are whitish-grey or 

 brown, often with dark zigzag streaks; and the hind-wings are generally paler, and without 

 markings. The larvce have sixteen legs, and are either provided with hairy warts or are covered 

 with soft hair ; they change to a thick hairy pupa in a cocoon. The position of the wings is 

 sloping when at rest, and many of the species fly at night, while the males of others are active 

 in the daytime. 



GENUS I.— ORGYIA (OCHS.). 



Male with the body slender, the wings broad, and the hind-wings extending beyond the abdo- 

 men. The fore-wings are brown, generally with indistinct transverse lines, and a white spot near 

 the hinder angle. The males fly by day in search of the females, which have thick bodies, and very 

 short and rudimentary wings, and are perfectly incapable of flight. The larvae have tufts of hair 

 on segments 5 to 8 ; and two longer tufts of hair on the 2nd, and another on the 12th segment. 

 They feed on trees and shrubs from autumn to June, and the moths appear from June to August. 



* I. 0. Goiwstigma (Fabr.), {Scarce Vapourcr Moth). — Fore-wings of the male olive-brown, 

 with a marginal row of white spots, bordered inside with orange on the costa and inner margin ; 

 fringes spotted with dusky ; hind-wings dark brown. Expands from \\ to i), inches. The female 

 is grey, wingless, and the antenna; have one row of pectinations. Common in most parts of Europe 

 and Siberia, but scarce in the south of England. Tho Livva is black, streaked with rust-colour,
