When younger pale yellowish-brown, clouded with red or 

 orang-e-brown in the vicinity of the larger tubercles ; dorsal 

 line slightly darker brown, edged at each incision by a short 

 black dash, which is continued obliquely forwards to the 

 tubercle on the preceding segment; the included space or 

 triangle thus formed being dark purplish-brown ; the whitish 

 raised dots are surrounded with grey or reddish-brown ; head 

 pale brown, faintly marbled with reddish-brown, and having 

 a paler dot on each lobe ; undersurface and legs pale ochreous 

 tinged with green. (C. Fenn.) 



When very young this larva is bright red, almost 

 crimson. 



August till May, hybernating while very small ; on Fimis 

 sylvedris^ and sometimes on other species of fir. 



Pupa short and rather thick, abdomen tapering rapidly 

 off; eye-covers glossy ; tongue and limb-covers barred with 

 faint channelled sculpture ; antenna-covers very prettily 

 barred, showing the shaft and every tooth of the pectina- 

 tions ; wing-covers abundantly covered with, and rendered 

 dnll by, multitudes of cross and lengthwise minute channels 

 of sculpture ; segments plentifully pitted, except the smooth 

 hinder bands, which are narrow ; cremaster a strong thickened 

 triangular projection armed with two parallel spikes and a 

 few twisted bristles; colour red-brown, cremaster hardly 

 darker. In the ground, in a cocoon of silk and earth. 



The moth usually rests in the day time in the lower

 induced to flutter down to the ground, by a heavy blow upon 

 the trunk of the tree. Sometimes, when just emerged, or 

 when shaken down by a violent wind, it may be found upon 

 brambles, fern, or other herbage under the trees, sitting 

 always with deflected wings, and looking sufficiently like a 

 flake of red fir-bark. It may occasionally be captured at a 

 strong light. Found only about fir woods, but in them often 

 Qommon, throughout England, and in Scotland so far as
