122 LEPIDOPTERA. 



cremaster stout, conical, tipped with several fine hooked 

 bristles. Front portion, with the wing-covers, rich yellow, 

 the latter semi-transparent; abdominal segments reddish- 

 yellow. In a moderatel}- thick cocoon of silk and earth, in 

 the ground. 



In this condition through the winter. 



The moth hides among heather during the day, and raaj- be 

 disturbed by the footstep in hotweather, yet is far more readily 

 met with at dusk flying over the same plant. Apparently 

 common upon heaths throughout England and Ireland, 

 probably also Wales, since it is aliundaut in Glamorganshire 

 and Pembrokeshire. In Scotland it is found in Wigtownshire, 

 Clydesdale, Perthshire, the Edinburgh district; not commonly 

 in Aberdeenshire and Moray; and has been taken even in the 

 Orkneys. Abroad it seems only to have been recognised in 

 Holland and Central and Western Germany, and its further 

 range is somewhat doubtful.
