are bordered behind with a h'ght band ; hind-wing's with the continuation of the double line, but 

 it projects much further towards the hind margin on the costa than it does on the inner margin 

 of the fore-wings. Expands about \\ inches. Inhabits Austria, Hungary, &c. 



6. P. Aqitata (Hiibn.). — Wings white, hind margin and fringes grey, with brownish-yellow 

 and brown transverse lines, a scarcely-dentated white subtcrminal line, and fine black marginal 

 dots ; fore-wings with the tip divided with black, and a reddish-brown shaded streak running 

 from thence to the middle of the inner margin, the hindermost double stripe curved, and 

 running into the inner margin beyond the middle. Expands about i^ inches. A local 

 species, found in Central Europe from May to July. The larva is green, suffused with violet- 

 grey ; or brownish, with a dark macular line on the back, and a dark line on the sides above 

 the flesh-coloured angular marks. It feeds on Clematis in summer and autumn. 



*7. P. Vitalbata (VV. V.). — -Wings light brown, broadly pale ochreous on the costa, with 

 many rusty-brown transverse lines, which are dark brown in the central area, and suffused 

 towards the costa, and indistinct black central and marginal dots ; beyond the central dot runs 

 a blackish oblique band from near the base of the inner margin to the tip, and below this is the 

 whitish subterminal line. Expands from i to ij inches. Inhabits many parts of Europe and 

 Western Asia in June and July. The larva is bluish-green, with a darker streak on the back, 

 expanded into an oval spot, paler in the centre, and on the middle segments ; and with a 

 yellowish stripe on the sides. It feeds on Clematis in August and September. 



* 8. P. Tcrsata (W. V.). — Wings dust-colour, with many brown transverse lines, dotted with 

 black on the nervures beyond the middle ; a whitish and strongly zigzag subterminal line, and 

 fine black marginal dots ; the central area of the fore-wings projects in an angle in the middle 

 and below the costa, and the tip is divided with black. Expands about I5 inches. Inhabits 

 Central and Southern Europe, and Northern and Western Asia, in June and July. The larva 

 is greenish-grey or brown, spotted with darker, with a brown line on the back bordered with 

 white, pale and dark longitudinal lines, and a grey line on the sides. It feeds on Clematis in 

 September and October. {P. Testaceata, Hiibn., from South Germany, has shorter wings, the 

 subterminal line bordered with darker on the inside, and the hind margin without black dots.) 



9. P. Exoletaria (Herr.-Schaff.). — Greyish fawn-colour, all the wings with black central and 

 marginal dots, and a pale denticulated submarginal line ; fore -wings with some slightly 

 dentated blackish lines, with three black spots in front, a black angulated streak behind, and 

 a whitish spot on the inner margin. From Sicily. 



10. P. Radicaria (Lah.). — Rather larger than Tersata (expands about li inches) ; wings 

 grey, varied with yellowish, with no transverse lines in the basal area, the dots on the nervures 

 less conspicuous, the subterminal line less dentated, and the tip of the fore-wings divided by a 

 sharply-defined black dash, beneath which the ground-colour is pure yellow. Occurs at 

 Lausanne. Staudinger refers both this species and Testaceata to Testata, but with doubt. 



11. P. ^mulaia (Hiibn.). — Brownish-grey, the costa mottled, with dark transverse lines and 

 black marginal dots, the central area of the fore-wings only projecting into an angle below the 

 costa, and bordered behind by a light band divided by dusky, in which the nervures are strongly 

 dotted with black and white ; the subterminal line zigzag, and expanded into a blotch on the 

 inner margin. E.xpands about i^ inches. It is found in the Alps of South Bavaria, Austria, and 

 Carinthia in June. Larva greyish-green, with a black line on the back, expanded into spots on 

 the middle segments. It feeds on Clematis in September. 



12. P. Calligrapharia (Herr.-Schaff.). — Wings pale bluish-grey, dusted with brown, with 

 numerous indistinct brownish transverse lines and black marginal dots, the central area of the
