Expands from 2 to 2] inches. Not uncommon in most parts of Europe from May to August. 

 The larva is pale shining brown, varied with darker, with a small dark transverse wart on 

 each segment, but with no pale stripe on the sides, or only an indistinct one. It is found in 

 June and autumn on poplar, willow, and birch. The moth is figured at PI. 31, Fig. 6. 



*2. L. DictcEoidcs (Csp). — Very like Dictcea, but the dark brown longitudinal streak above 

 the inner margin of the fore-wings contains, instead of a white line, a long white triangular 

 spot, the base of which is placed on the hind margin, and is nearly half as long as 

 its height. The polar Y3.ne\.y Fri^ida (Zett.) is much darker. E.xpands from i^ to 2 inches. 

 Common in most parts of Northern and Central Europe in May and June. The larva is 

 much more glossy than that of Dictcca, and is darker, and of a more uniform violet-brown, 

 purplish-brown, or green, with a broad sulphur-yellow stripe on each side. It is found only 

 on birch in July, September, and October. 



GENUS XVI. — DRYNOBIA (DUP.). 



Fore-wings broad, with the tips rectangular, and a well-marked tooth of scabs on the inner 

 margin. They are violet-grey, with double black transverse stripes, filled up with paler. The 

 larvae are naked, and without lustre. They feed in August and September, and the moths 

 appear in May and June. 



1, D. Velitaris (Knoch.). — Fore-wings with the first stripe curved, and the hindmost slightly 

 dentated ; the tips are whitish on the costa, and dark brown on the inner margin. The hind- 

 wings are brownish-grey, with a suffused pale streak in the middle. Expands from ij to 

 2 inches. A rather scarce and local insect in Central Europe, but not found in Britain. The 

 larva is yellowish-green, with six longitudinal lines formed of white dots, and a carmine-red 

 stripe on the sides, bordered with whitish below. It feeds on oaks, preferring stunted bushes. 



2. D. Mclagona (Scriba). — Resembles Vdilaris, but the first transverse stripe forms two 

 angles, and the tip of the fore-wings is dark brown on the costa, and ashy-grey on the hind 

 margin. Expands from \\ to \\ inches. Confined to the southern half of Central Europe, 

 and still scarcer than the last species. The larva resembles that of Velitaris, but is whitish- 

 green, and the lateral stripe is not red above, but only slightly marked with reddish here and 

 there. It lives on beech. 



GENUS XVII. — DRYMONIA (HUBN.). 



Fore-wings broad, with the tips obtuse, grey, with double black lines, filled up with paler, 

 the last of which is dentated. There is also an indistinct waved line before the hind margin, 

 and the tooth of scales on the inner margin is very slight. The larvai are without pro- 

 tuberances. They feed from June to August, and the moths appear from March to May. 



I. D. Querna (VV. V.). — The fore-wings are violet-grey, with two double black transverse 

 stripes filled up with white ; the hinder portion of the central area is whitish, with a large 

 white central lunule; hind-wings white. Expands from i^ to i\ inches. A scarce and local 

 insect in Central Euiope, except Britain. The larva is dark green, with two yellow lines on 

 the back, and a yellow stripe on the sides. It lives on oak. 



* 2. D. Chaonia (W. V.). — The fore-wings resemble those of Oiirnia, and are likewise more 

 or less whitish before the hinder transverse stripe, but they are darker grc)', and the white 

 lunule is replaced by a black one. The hind-wings arc pale grey, with a whitish stripe in 

 the middle. Size of Querna. Found throughout Central Europe, but commoner in some
