BARRED RED. 269 



106, Fig. 7.d) were pale greenish yellow when laid, May 17 to 

 20 ; the larvae hatched out from May 31 to June 2. 



The caterpillar, which is also depicted on the plate, is reddish 

 brown, mottled with yellowish brown. It feeds on birch, sallow, 

 ash, etc., from June to August. 



The moth, as a rule, does not emerge until the following 

 spring, but sometimes specimens will come out the same year. 



Although widely distributed over nearly the whole of the 

 British Isles, the species seems to be rarely met with in large 

 numbers. The range abroad extends to Amurland, Corea, and 

 Japan. 



Barred Red {Ellopia {Hylaea) prosapiaria). 



The typical form of this species is depicted on Plate 108, 

 Figs. 4 ^ , 5 ? , and Fig. 3 on the same plate represents ab. 

 Prasinaria, Hiibner, a form not uncommon in Germany (whence 

 came the example figured), Switzerland, and other parts of the 

 continent, but which is very rare in Britain, and has been 

 recorded from Kent and Suffolk. Sometimes, but chiefly in 

 Scotland, the colour varies to a greyish or even yellowish tint ; 

 the cross lines are often parallel or nearly so, and frequently 

 approach each other about the middle ; the usual white edging 

 to the cross lines is occasionally absent, and the enclosed space 

 in such specimens is hardly darker than the general colour. 



On Plate 106, Fig. i, will be found a figure of the caterpillar, 

 which is tawny brown with white- edged, connected reddish 

 marks along the back. It feeds, from September to May, on 

 Scots pine {Pmus sylvestris\ and occasionally on larch. The 

 moth is out in June and July, and sometimes in September. It 

 may be jarred from the pine boughs, and is not infrequently 

 seen resting on foliage of the undergrowth. Generally dis- 

 tributed in fir-woods throughout Great Britain, and widely 

 spread in Ireland. 



The range abroad extends to East Siberia.
