68 THE MOTHS OF THE BRITISH ISLES. 



as Derbyshire and Stafifordshire. Farther north, and in Wales 

 and Scotland, it has been rarely met with. Recorded by 

 Birchall to be not uncommon at Killarney ; but Kane states that 

 he has never seen an Irish specimen. 



The species occurs locally throughout Central Europe, also in 

 Transylvania, Northern and Central Italy, and Eastern Armenia. 

 In Ussuri, and Japan, it is represented by the form dodonldcs, 

 Staud. 



The Lunar Marbled Brown {Drymonia chaonia). 



The fore wings of this moth (Plate 28, Fig. 2) are dark fuscous, 

 almost blackish, a short white line near the base ; the central 

 third is white clouded with the ground colour and limited by 

 white edged black wavy lines ; a black crescent just above the 

 centre of the wing. Hind wings smoky grey with a pale curved 

 line. The ^%'g^ which is bluish white in colour, is of the usual 

 Notodont shape. Caterpillar green, merging into bluish -green 

 on the back ; the lines are pale yellow, or creamy white, that 

 along the black margined spiracles is rather broad and is some- 

 times tinged with reddish on the three front rings. Head 

 green, mouth marked with pale yellow. Feeds in June, July, 

 and August on oak. From about a dozen eggs that I had in 

 May, 1907, the caterpillars hatched on the 13th of the month. 

 Only one got through safely to the chrysalis stage which it 

 reached at the end of June. On June 26th some half-grown 

 and smaller caterpillars were received from the New Forest, 

 only one of these was seen on July 19th, but it was then nearly 

 full grown and appeared to be quite healthy, and others had 

 pupated or died. 



The chrysalis is deep red brown, enclosed in a silken cocoon 

 covered with particles of earth ; generally found at the roots of 

 isolated oak trees (Plate 29, Figs, i, \d). 



The moth emerges in May, sometimes at the end of April,
