DREPANULID^. 75 



beneath with dark olive or blackish-brown. This dark colour 

 is continued on the sides, and encloses a large diamond- 

 shaped paler blotch extending from the sixth to eleventh 

 segment; the remaining posterior segments darker with a 

 whitish lateral line. Head yellowish-brown, dusted with 

 red-brown ; under surface and legs very pale brown or whitish 

 ochreous, tinged with greenish. (C. Fenn.) 



June and July, and as a second generation, in September 

 and October. On beech {Fagus sylvaUca). 



Pupa moderately stout, tapering considerably to the tail, 

 which is fixed by anal hooks to the cocoon ; dull dark bluish- 

 grey with whitish efflorescence ; incisions dull orange. In a 

 dense cocoon of soft whitish silk tinged with orange, spun in 

 the angle formed by a turued-down leaf, or between two 

 leaves. (C. Fenn.) 



Remaining in pupa through the winter. 



The male flies about beech-trees in the daytime, sometimes 

 high up, at others visiting the lower boughs. Both sexes fly 

 after dark, but are strictly confined to the neighbourhood of 

 the beech-woods, and usually to those which grow in chalk 

 districts. When not flying it is not difficult to disturb them, 

 in the daytime, by shaking or beating the leafy portions of 

 the branches with a long stick, since the moth, like its allies, 

 sits flatly upon a leaf. Common in beech-woods in Kent, 

 Essex, Sussex, Surrey, Berkshire, Buckinghamshire, and 

 Oxfordshire, and doubtless in Hants, Wilts, and Dorset. 

 Also found in Norfolk, Suffolk, Cambridgeshire, Hereford- 

 shire, Gloucestershire and Somerset, though perhaps not so 

 commonly, and in Devon local and rare. This appears to be 

 the extent of its range in these Islands. Abroad it is common 

 in beech-woods throughout Central Europe, also in Piedmont 

 and Asia Minor.
