304 L EPID OP TERA . 



or aljsence of clavker clouding; or from tlie deptli of colour 

 of the apical cloud and its extension qnite to tlie central 

 band, or becoming intensified to dark brown or even black- 

 brown. 



On the wing from June till August, in a single 

 generation. 



Larva apparently undescribed. It is believed to feed on 

 the flowers of Eupatormni caimabiiium in September, and on 

 becoming full-fed to descend to the ground and spin up in 

 a short broken bit of the old stem of this plant. A number 

 of such broken pieces picked from the ground by Mr. W. 

 Warren furnished him with numerous larvae, many of 

 them ichneumoned, but some living, from wliich he reared 

 the moths. 



The moth hides during the day in the clumps of 

 Uupatorium, and if disturbed falls down, unless the sunshine 

 is bright aud warm, in which case it will fly a short 

 distance. In a particularly warm tituation it will occa- 

 sionally fly of its own accord in the afternoon sunshine, and 

 at sunset it becomes lively and buzzes about among its food- 

 plants, but from the roughness of the latter it quickly 

 becomes worn, and loses all its beauty. In southern and 

 eastern districts it inhabits fens and marshes, but in the 

 moist climate of the west, where the hemp agrimony grows 

 in the hedges, the moth is often to be found in lanes and 

 waysides. To be found in almost, or quite, all our Southern 

 and Eastern counties ; and in Gloucestershire, Hereford- 

 shire, Hertfordshire, Cambridgeshire. Cheshire, Lancashire, 

 South Durham and Westmoreland; and in Wales commonly 

 in Pembrokeshire ; but I have no further records in the 

 United Kingdom. Abroad it inhabits a great part of Central 

 and Southern Europe and Livonia.
