with numerous whitish lines, and a Ijlack-ish l)lotch on the 

 ninth segment; whitish between the prolegs. 



June and July, and a partial second generation in Sep- 

 tember ; on oak and sometimes birch ; feeding at night ; 

 resting by day on the twigs and leaves. 



Pupa flattened and very like that ot a little butterfly; the 

 head-cover smooth and scpiared, and the front portion ex- 

 tremely truncate, the wing shoulders projecting in a small 

 point on each side; limb and antenna-covers closely packed 

 and but little indicated; wing-covers very smooth, aud only 

 showing indications of the nervures ; dorsal region rough- 

 ened, and minutely pitted and wrinkled, especially in the 

 front part of each segment, also ornamented with a small 

 row of brown spots on each ; abdomen elongated and very 

 gently tapering ; all except the hind borders of the segments 

 roughened with minute pitting; cremaster long and thick, 

 rounded and bluntly terminated, but furnished with minute 

 curled bristles; colour bright green, pale yellowish-brown, 

 or pinkish-brown ; at the back of each wing-cover is a brown 

 streak ; cremaster dark brown. On a small silken carpet, on 

 the underside of a fallen oak-leaf; the bristles of the tail 

 fixed in the silk, and a thread of the same placed securely 

 across the back. 



The moth sits during the day on the underside of a leaf of 

 oak or birch, among undergrowth, or in the lower branches 

 of the trees, and is readily disturbed by the beating-stick, 

 when it flies hurriedly to a similar shelter. At dusk it flies 

 gently about wood paths and the more open parts of woods, 

 and will then come occasionally to the sugar placed on trees 

 for the benefit of Nodncr, or, in the second generatiou. to 

 heather-bloom. Later at night it is not insensible to the 

 attractions of a strong light. Not wholly confined to woods, 

 but fretiuenting oaks in more open ground occasionally ; for-

 whence it appears now to have disappeared. Still quite
