As restricted, it contains only two or three species from the 

 European region. 



1. G-. papilionaria, L. 45-56 mm. Head green. Fore wings 

 green; first and second lines whitish, indistinct, waved; sub- 

 terminal formed by whitish dots ; a darker green linear discal 

 mark; tips of cilia white. Hindwings as forewings, but first 

 line absent ; termen waved, bent. 



Britain to Ross, Ireland, rather common ; N. and C. Europe, N. 

 Asia; 7. Larva green, yellow -speckled, back reticulated with 

 paler; 3 with one, 6-9 with two rosy-tipped projections ; 12 and 

 13 rosy on back; spiracular line yellow; head reddish: on 

 birch, hazel, etc. ; 9-5. 



4. PSBTJDOTERPNA, Hb. 



Antennae in $ bipectinated, towards apex simple. Palpi 

 rough -scaled. Thorax densely hairy beneath. Abdomen with 

 dorsal crests. Forewings: 10 out of 9, 11 sometimes anasto- 

 mosing with 12 and 10. Hindwings : 6 and 7 separate, 8 

 approximated to cell towards base, diverging from middle. 



A genus of some considerable extent, but principally Indo- 

 Malayan and Australian, correlated with the preceding ; there 

 are three strictly European species. 



1. P. pruinata, Hufn. (cytisaria, Schiff.) 32-35 mm. Head

 speckled ; dorsal line darker; subdorsal pale yellowish -green ; 

 spiracular rosy-white, purple-edged beneath, with a branch 

 down third leg ; head and 2 bicuspidate, tips dark red : on

Hindwings : 5 fully developed, parallel to 4, rising from 

 about or below middle of transverse vein, 8 free or anastomosing 

 shortly near base or seldom from near base to beyond middle
