MoMA — Bryophila. 151 



10. A. Abscondita (Tr.). — Differs from EuphorbicB by the rather pointed fore-wings, which 

 are uniform dark grey, dusted with whitish, so that the pattern is wholly obliterated. Expands 

 about i^ inches. It occurs in North-Ecistern Germany, Lapland, and probably Russia in May 

 and July. The larva differs from that of EuphorbicB in having a red stripe on the sides, but 

 no red spot on the 3rd segment. It feeds on heath and spurge in June, August, and 

 September. 



* II. A. Rumicis (Linn.). — Fore-wings brownish-grey, varied with pale grey, with a row of 

 whitish spots before the hind margin. The transverse lines are double, the elbowed line 

 strongly dentated, and there is a white spot above the inner margin. The stigmata are distinct 

 and the hind-wings are grey, with the hind margin broadly darker. Expands from \\ to 

 i^ inches. Common throughout Europe, North Africa, and Northern and Western Asia from 

 May to August. The larva is dark brown, covered with short rusty-yellow hair, with a white 

 stripe on the sides spotted with red, and two oblique white spots on both sides of the back. 

 It feeds on low plants in June, and in August and September. 



* 12. A. Megacephala (W. V.). — Resembles Aceris, but the fore-wings are darker grey, and more 

 thickly and coarsely dusted with brownish ; and between the reniform stigma and the elbowed line 

 is a conspicuous pale yellowish-white space ; the hind-wings are dusted with brown, but in the 

 male only at the hind margin. Expands from \\ to if inches. Common throughout Europe and 

 Northern and Western Asia from May to July. The larva is pale brown, with the back blackish ; 

 with hairy warts, and a large square yellowish- white spot on the nth segment, bordered with 

 black. It feeds on poplar, &c., from July to October. 



* 13. A. Aceris (Linn.). — Fore-wings pale grey, dusted with darker, with wavy fringes, and 

 double transverse lines ; the stigmata are large and separate, but the black longitudinal streaks 

 are either wanting, or else only the basal one is faintly indicated ; the hind-wings are white, with 

 the nervures dusted with darker. Size oi Megacephala. Common in most parts of Europe in May 

 and June. The larva is yellow, with thick yellowish-white hair, and large white spots on the 

 back, bordered with black, adjoining long tapering red and yellow tufts of hair. It feeds on 

 various trees, especially sycamore and horse-chestnut, in August and September. The moth is 

 figured at Pi. 32, Fig. 8. 



GENUS III. — MOMA (HUBN.). 



The thorax is short and broad, and slightly crested in front, with its hairs widened at the 

 extremities like scales ; and the abdomen is crested. The legs are thinly hairy, and the fore-wings 

 have a slightly oblique, regularly curved hind margin, with rounded fringes ; and the hind-wings 

 are also rounded. The only species, * M. Orion (Esp.), has pale green fore-wings, with three white 

 longitudinal streaks, three irregular black transverse stripes, composed of spots and dashes, and 

 triangular black spots on the hind margin, edged with white in front. The hind-wings are greyish- 

 brown, with a black spot divided with white at the anal angle, and all the fringes are chequered 

 with brown and white. Expands from l^ to i^ inches. It is common on tree-trunks in ^lay and 

 June in many parts of Europe, though rare in England. The larva is black, with large pale yellow 

 spots on the back of segments 3, 5, and 8. It feeds on oak from July to September. The moth 

 and larva are figured at PI. 33, Fig. 2, a, b. 



GENUS IV. — BRYOPHILA (TR.). 



Small moths, with slender bodies ; the palpi small, the thorax not crested in front, but the 

 hair raised behind, and the legs thinly haired. The fore-wine's are broad, with the tips nearly
