170 LEPIDOPTERA. 



greenish -Avhite, with a black clash at the beginning of each 

 segment, except the anterior ones, which are marked in the 

 middle by a somewhat square spot and a small black spot 

 at the base of each anterior leg ; on the undersnrface a faint 

 greenish-white central line, with a black elongate mark upon 

 it, at about the middle of each segment from the fifth to 

 the ninth ; a little more behind on each side of the central 

 line are twin black specks, and a couple of greenish-white 

 spots on either side at the front of each of these five seg- 

 ments; a very small black mark is at the inside base of each 

 true leg, and these limbs are glistening ; usual raised dots 

 excessively small, and dusky, each emitting a fine bristly 

 hair. (W. Bnclcler.) 



August or September till June, on Vmca 5«7-&a;^« and other 

 shaggy lichens growing upon the trunks or branches of oak, 

 beech, hawthorn, larch, and spruce-fir, feeding especially upon 

 the tips of the lichen-fronds or filaments ; feeding only while 

 the lichen is moist and fresh. Mr. Buckler was careful to 

 moisten it with water three times a day, and frequently to 

 change the food. 



Pupa half an inch long, slender ; eye-covers rather pro- 

 minent ; abdominal divisions deeply cut ; anal tip bearing a 

 spike finely forked at its extremity ; whole surface glossy ; 

 wing-covers olive-green ; the other parts brown, except the 

 anal spike, which is blackish. (W. Buckler.) In a small 

 cavity among moss, but so little secured that it will roll out 

 if the moss is handled. 



The moth sits during the day in or upon the branches of 

 trees, usually on the low spreading boughs of oak, and is 

 rather sluggish ; if beaten out it flies to the ground at a very 

 short distance. Its natural flight is at dusk. Its principal 

 home with us is in the New Forest. Hants, and here it is 

 usually to be found in some numbers ; in very favourable 

 years in plenty. I have taken it in Woolmer Forest, in the 

 same county. Elsewhere it is excessively local, and usually
