THE DOTTED FOOTMAN. 1 87 



that they all seem to get active at almost the same moment, and 

 settle again in the same way at the end of their first flight, 

 which lasts about half an hour. After dark the ra)'s of an 

 acetylene lamp directed downwards into the bushes will attract 

 them from their retreat. Occasionally they visit " sugar." 



Abroad this is a southern species, but its range extends to 

 Western Germany, the Tyrol, Switzerland, and South Hungary, 

 as well as to England ; also to Asia Minor. 



The Orange Footman {Lithosia sororcuhi). 



This moth is orange yellow on the fore wings, and a paler 

 shade of the same colour on the hind wings. Except that the 

 tint is brighter in some specimens and darker in others, there is 

 nothing to mention in the way of aberration. (Plate 99, Figs. 6, 7.) 



The caterpillar is white on the back with five black stripes, 

 the outer ones broader than the others ; all these stripes are 

 broken up by brownish patches, and they fail to show at all on 

 the eighth ring, which, therefore, is conspicuously white ; the 

 sides are smoky grey marked with white on the second and 

 third rings ; the warts are reddish, bearing smoky grey hairs. 

 It may be found from July to September on the lichens growing 

 on the trunks of oak trees. The moth does not appear until the 

 following May or June, when it may be beaten from branches. 

 Not uncommon in the woods, chiefly oak, of Norfolk, Suflblk, 

 Essex, Kent, Surrey, Hampshire, and Dorset ; it also occurs in 

 Cambridgeshire and Sussex. In Berkshire and Bucks it is 

 fairly common, but seems to affect the beech woods in those 

 counties. Recorded from Ireland by Birchall, who stated that 

 it was abundant at Killarney. 



The Dotted Footman {Fdosia imisardd). 



The fore wings are jjale grey suftused with pale reddish-
