124 European Butterflies axd RIotiis. 



* C. Glaucaia, Scop. {Spinnla, W. V.), is wliite, fore-wings with a large brown spot, varied with 

 leaden grey on the inner margin, and a pale grey spot above it, in whicli the nervures form 

 a fine silvery pattern, resembling a stag's horn. In repose it slopes its wings rather steeply. 

 Expands a little under i inch. It is common in Southern and Central Europe, and is often 

 disturbed by beating hedges, when it rushes down to the end of a twig, and sits there, its white 

 colour making it look very conspicuous, notwithstanding its small size. The larva is brown, with 

 a whitish spot on the back, and warty tubercles on the 3rd and 4th segments. The moth is 

 figured at PI. 30, Fig. i. 



GENUS II. — PLATYPTERYX (LA.SP.). 



The species belonging to this and the following genus have the fore-wings more or less 

 hooked, and are therefore frequently called " Hook-tips." The wings are brown or yellowish, with 

 transverse lines. In Platyptcryx the antenna; are ciliated to the extremity, the pectinations being 

 shorter in the female, in which sex the frenulum is absent. The hind tibias have spurs at the end 

 only. The hind margins of the wings are dentated in the first species. The larvse are finely 

 hairy, with warty tubercles. 



* I. P. Laccrtinaria (Linn.). — Fore-wings pale grey, dusted with brown, and with two 

 transverse brown lines ; hind-wings whitish. Expands from i^ to \\ inches. It is common 

 throughout Europe, the south excepted. The larva is brown, with large wart-like tubercles on 

 the 3rd and 4th segments, and small warts on the others. It feeds on birch and elder. 



* 2. P. Falcataria (Linn.). — Pale yellow, with brown waved lines, fore-wings dusted with 

 darker, with a grey egg-shaped spot, veined with black, in the middle. Size of Laccrtinaria- 

 Common in most parts of Europe and Western Asia. The larva is green, with fleshy points on 

 segments 3 to 6 ; and reddish-brown on the hinder part of the back. It feeds on birch and 

 elder. The moth is figured at PI. 30, Fig. 3. 



3. P. Ciirvatula (Borkh.). — Violet-brown, with dark brown wavy lines, the fore-wings with two 

 oblique rows of black dots across the middle. Size of the last species. Inhabits the greater part 

 of Central Europe, but is rather scarce, and is the only species of the family not found in Britain. 

 The larva is brown, with fleshy points on the 4th and 5th segments, and lives on elm. 



GENUS III. — DREPANA (SCHRANIC). 



Closely allied to Platypteryx, but the fore-wings are less pointed, except in Siciila, and 

 therefore less distinctly hooked. The antennae of the male are not pectinated at the extremity, 

 and those of the female are simple. The hind tibije are furnished with four spurs. 



* \. D. Sicjila (W. v.). — Fawn-colour, with brown zigzag lines, and an irregular brown blotch 

 or band in the middle of the fore-wings, dotted with pale yellow ; and with several oblique zigzag 

 dusky lines. Expands about ij inches. It is found throughout the greater part of Central 

 Europe, but appears to be scarce everywhere. The larva is reddish-brown, varied with darker ; 

 the back is lemon-yellow, with two tubercles on the 4th segment. It feeds on oak and birch. 



* 2. D. Binaria (Hufn.), Haimda (W. V.). — Wings paler or darker rust-colour, suffused with 

 violet-grey, with two pale transverse lines ; fore-wings with two large black dots in the middle. 

 Expands from i to ij inches. Widely distributed in Central and Southern Europe, but 

 commoner in some localities than in others. The larva is brownish-yellow, and greenish-brown 

 on the front segments, with two pale subdorsal lines. It lives on oak. The moth is figured at 

 PI. 30, Fig. 2.
