EUGO.VIA. 299 



with two dark transverse lines ; hind-wings with costa and inner margin of equal length, 

 and a projection in the middle of the hind margin ; antennse of the male pectinated ; the 

 thorax and femora downy. The larvE have ten legs, and are narrower behind the head, 

 and are frequently provided with humps. They feed on trees in summer, undergo their 

 transformations in a thin cocoon, and the moths appear from July to October. The hind 

 tibis are furnished in the first two species with four spurs, and in the others with terminal 

 spurs only. 



*i. E. Autuinnaria (Werneb.), Alniaria (W. V.). — Wings ochre-yellow, darker towards the 

 hind margins, and speckled with violet-brown ; fore-wings with two transverse lines, composed 

 of agglomerations of dark specks. The wings are more evenly dcntated than in the other 

 species of the genus. Expands from if to 2 inches. Inhabits Central and Northern Europe; 

 rare in England. The larva is grey or brown, with small warty prominences on the 6th, 7th, 

 and loth segments, and with a bifid prominence on the 12th segment. It feeds on alder, 

 aspen, apple, &c. The transformations are figured at PI. 43, Fig. 2, a — c. 



*2. E. Qticirinaria (Hufn.), Angnlaria (W. V.). — All the wings paler or brighter ochre-yellow, 

 with the fringes chequered with white and brown, the fore-wings often finely speckled with 

 violet-brown, with two well-marked brown transverse lines, the outermost continued across 

 the hind-wings ; paler on the under surface, with the tips broadly violet-brown ; and the hind- 

 wings are also violet-brown beneath. In the variety Carpinaria (Hiibn.) the basal and marginal 

 areas are clouded with violet-brown. Expands from \\ to \\ inches. Common in Central 

 Europe. The larva is reddish-brown, with smaller or larger warts on segments 6, 7, 10, and 

 12. It feeds on oak and lime. 



*3. E. Erosaria (Borkh.). — Fore-wings ochre-yellow, often speckled with brownish, with two 

 distinct brown transverse lines, the tips not darker beneath ; hind-wings brownish, violet-brown 

 beneath, especially towards the hind margin ; fringes pale yellow, spotted with brown. Size of 

 Qucrcinaria. The variety Ockraria, Steph. (Tiliaria, Hiibn. ; Qucrcinaria, Borkh.), is paler, and 

 not speckled with brown. Common in Central and Southern Europe. The larva is pale grey 

 or pale brown, with the 7th segment thickened, and humps on several of the other segrqents, 

 especially on the loth and 12th. It lives on oak. 



4. E. Qucrcaria (Hiibn.). — Very like Erosaria, but smaller (expands about \\ inches) ; the 

 wings are sulphur-yellow, the fore-wings with two brown transverse lines bordered with 

 lighter, and pale }-ellow on the under side. It is found in Austro-Hungary, Spain, and perhaps 

 also on the Rhine. 



*5- E. Fiiscantaria (Haw.). — Wings ochre-yellow, speckled with violet-grey, and yiolet-brown 

 towards the hind margins ; the forcrwings with two dark brown transverse lines, strongly con- 

 verging on the inner margin. On the under side the hind-wings and the tips of the fore-wings 

 are violet-brown. Expands about \\ inches, or a little more. Inhabits England, Holland, 

 North France, and Silesia, but always rare. The larva is green, with no humps, but with 

 brown bands on the 7th, loth, and 12th segments. It feeds on ash. {E. Ejfractaria, Freyer, 

 from Sarepta, is allied to the last, but yellower; the transverse lines of the fore-wings are 

 blackish, and there is an irregular rust-coloured' spot between them ; the hind margin of the 

 hind-wings is broadly reddish.) 



*6. E. Alniaria (Linn.), Tiliaria (Borkh.), Canaria (Hiibn.), {Canary-shouldered TJiorn). — 

 Wings ochre-yellow, sprinkled with brown, the fore-wings with two brown parallel and slightly 

 curved transverse lines, the under side of the hind-wings speckled with brown, and with a 

 large dark brown central spot ; head and thorax sulphur-yellow. Expands from \\ to \\ inches.
