300 EuKOPEA.v Butterflies and Moths. 



Common tliroughout Central Europe. The larva is brown, marbled with darker, with humps 

 on the 6th, 7th, 9th, and loth segments, and a bifid elevation on the I2th segment. It feeds 

 on lime and birch in May and June. 



GENUS v.— SELENIA (HUI3N.). 



Middle-sized moths, with moderately stout bodies, tlie fore-wings projecting above the 

 middle of the hind margin ; hind-wings more or less deeply excavated between nervures 4 

 and 6. All the wings are yellow or brownish, finely dusted with darker ; the fore-wings 

 whitish on the costa, with two dark transverse lines, which are not dentated, but expanded 

 into spots on the costa, and a dark central shade ; the outermost line is continued on the 

 hind-wings, and there is also a large dark lunule extending to nervure 5 ; the under side is 

 marbled with bright colours, and there is generally a whitish semi-transparent lunule on all 

 the wings. The antenna; of the male are pectinated, and those of the female are serrated. 

 The larvE are stout, with the front segments much more slender. The third pair of true 

 legs are much larger than the others, and the 8th and 9th segments are much thickened. 

 There are two or three broods, which feed from June to September, and undergo their 

 transformations in a slight cocoon ; and the moths of the summer broods are much smaller 

 than those of the spring or autumn broods. 



*i. 5. Tetralunaria (Hufn.), Illustraria (Hiibn.). — Wings reddish-brown, violet-grey in the 

 marginal area, and with white central lunules ; the outermost transverse line of the fore- 

 wings curved, and the hind-wings considerably dentated. Expands from \\ to if inches. 

 Inhabits Central Europe from May to September. The larva is of a bark-like grey, with 

 paler and darker spots, and a prominence on the 6th segment. It feeds on sloe, rose, &c. 

 The transformations are figured at PI. 43, Fig. 3, a — c. 



*2. S. Luuaria (W. V.). — Wings ochreous-yellow, dusted with brown, with whitish central 

 lunules, which are bordered with black on the hind-wings ; the outermost transverse line 

 of the fore-wings is straight, and the hind-wings are very strongly dentated. Expands 

 about if inches. The summer brood, Dehtnaria (Hiibn.), is considerably smaller, the wings 

 very slightly dentated, the central lunule of the fore-wings less distinct, and that of the hind- 

 wings only slightly surrounded with darker, but much more distinct than in the following 

 species, from which it may also be distinguished by its different colour, and by the central 

 shade being close to the second line on the costa. Inhabits the greater part of Europe 

 from May to September. The larva is reddish-brown, with darker prominences, and feeds on 

 sloe, lime, &c. 



*3. 5. Bilunaria (Esp.), Illuuaria (Hiibn.), {Early Tltoni). — Wings pale ochreous-grey, 

 slightly shading into violet-grey, and not much dentated, with no distinct central lunules ; 

 and the central shade of the fore-wings is some distance from the second line on the costa. 

 Expands from \\ to if inches. Common in Northern and Central Europe and Northern Asia 

 from March to September. The larva is of a bark-like grey or brown, with bifid prominences 

 on the 9th and loth segments. It feeds on alder, willow, &c. The moth and larva are 

 figured at PI. 44, Fig. \, a, b. 



GENUS VI. — THERAPIS (HUBN.). 

 Body slender ; the fore-wings with a rounded projection on the hind margin ; the costa 

 of the hind-wings rather long ; the antennae of the male pectinated. The larva is thick, 

 without protuberances, and undergoes its transformations in the ground. The only species,
