Bryophila. 153 



transverse lines are not dentated, and scarcely bordered with lighter, and the elbowed line is 

 slightly curved. The hind-wings are pale brownish-grey, with the fringes whitish at the ends. 

 Size of Pcrla. Inhabits Southern Europe, Austria, Bohemia, and, it is said, also Sweden and 

 Alsace ; it likewise occurs in Western Asia. 



6.B. Raptricula (Hiibn.). — Fore-wings blackish slate-colour, with the markings very indistinct ; 

 the transverse lines are slender, not dentated, and indistinctly double, the inner line composed of 

 two crescents, and the elbowed line slightly curved, and filled up with whitish above the inner 

 margin; the hind-wings are whitish, and brown towards the hind margins. The \2.x\<z\.y Dcccptriaila 

 (Hiibn.) is reddish, with a broad brownish longitudinal stripe running across the fore -wings. Size 

 of Miiralis. Inhabits a great part of Europe, except the north-west, and Western Asia. The 

 larva is bluish-grey, with two stripes on the back, spotted with yellow and white. It feeds on 

 Sticta pidnionaria. {B. Oxybicnsis, Mill., found at Cannes in August and September, has broader 

 and paler fore-wings, and the black longitudinal line is better marked, traversing the whole wing, 

 and even extending to the base. The antenna are more slender than in Raptricula. There is a 

 reddish variety corresponding to Deccptricula. The larva is supposed to feed on lichens growing 

 on the trunks of olive-trees.) 



7. B. Ereptricula (Tr.). — Fore-wings dark brown, with the base, tip, and inner margin whitish; 

 the transverse lines are not dentated, and the elbowed line is indistinctly double, and slightly 

 curved ; the hind-wings are pale grey. The variety RaviUa (Hiibn.) is varied with reddish in the 

 middle, and behind the elbowed line; and the Spanish variety Vandalusice (Dup.) is smaller and 

 paler. Size ol Perla. Common in Southern and South-Central Europe in gardens, and on walls and 

 houses. The larva is blue, with a black line on the back, and a zigzag yellowish-red stripe on the 

 sides, bordered below with black. It feeds on lichens on walls. (B. Contristaiis, Led., from Greece 

 and Syria, is allied to Strigii/a, but is a third larger ; the fore-wings are very variable, but 

 generally dull greenish-ash, more or less suffused with copper, and the hind-wings are reddish- 

 copper. B. Petrea, Guen., from Andalusia, has the fore-wings clouded with greenish-brown, grey, 

 and black ; the stigmata are black, the reniform stigma varied with yellowish-grey, and the hind- 

 wings are coppery-brown. B. Pineti, Ramb., also from Spain, has brown fore-wings, the lines 

 darker, the innermost edged outside with yellowish, and composed of two crescents, meeting in 

 a sharp angle turned outwards, and the hindmost much curved; the other markings indistinct. 

 Hind-wings whitish, darker towards the hind margins.) 



FAMILY III.— ORTHOSID^. 



Small or middle-sized moths, the body generally stout, rarely slender ; the palpi of ordinary 

 size, with the last joint distinct ; the tongue generally strong, and the antenna; of the male often 

 pectinated. The thorax is rounded in front, seldom with rectangular, and never with projecting 

 shoulders ; the hind-wings are contracted below the tips, and the hind tibiae are longer than the 

 femora, with strong spurs. The species included in this family differ considerably, and have been 

 divided into five families ; but they all pass insensibly into one another. We may include in the 

 Leucanidce the genera Siinyva to Segetia ; in the Caradrinidce, Stilbia to Rusiiia; in the Orthosida, 

 Asteroscopus to Gortyna ; in the Cerastidce, Xanthia to Orrhodia ; and in the AmphipyridtB, 

 Mecoptera to Amphipyra. They fly at night, and the first and third groups slope their wings when 

 at rest, and the others lay them flat over one another. The larva; are generallynaked, and without 

 protuberances.
