330 THE MOTHS OF THE BRITISH ISLES. 



The Clouded Drab (Tce?iioca??iJ>a incertd). 



Six specimens of this most variable species are shown on 

 Plate 157, Figs, i to 6. To refer in detail to all the forms, 

 named or otherwise, would occupy much space, so that it can 

 only be stated here that the general colour of the fore wings 

 ranges from pale greyish brown, through various shades of 

 reddish brown, to deep brown or purplish brown ; the darker 

 greys range through slaty grey to purplish black. In all the 

 lighter shades the wings are usually much variegated, but they 

 may be nearly or quite plain. 



The ^'g% is yellowish white with brown girdled dot 

 The caterpillar is green, minutely freckled with whitish ; three 

 white lines on the back, the central one broadest ; a white 

 stripe, edged above with black, along the sides ; usual dots 

 black, minute, ringed with whitish ; head yellowish green with 

 a few black dots. It feeds on sallow, oak, hawthorn, also on 

 apple, elm, etc. (Plate 156, Fig. 2.) The moth is generally to be 

 found at sallow-bloom in almost every part of the British Isles. 



The Twin-spotted Quaker {Tceniocampa mtmda). 



The fore wings range in ground colour from very pale 

 ochreous (typical) or pale greyish (var. pallida, Tutt), through 

 reddish shades to a dingy brown. The black or brownish twin 

 spots on the middle of the submarginal line are sometimes 

 accompanied by others above and below them (var. gemiiiatus). 

 In var. hnmaculata, Stand., the "twin spots," and also the 

 others, are absent. (Plate 158, Figs. 11, 12.) 



The caterpillar (Plate 159, Fig. i) is pale brown minutely 

 freckled with darker ; a whitish line along the centre of the 

 back finely edged with black ; , a broad velvety black stripe, 

 along the sides, edged with whitish ; head reddish brown.
