TORTRICID^—HETEROGNOMON. 195 



head dull brown or brownish-ochreous ; thorax pale yellow ; 

 abdomen whitish-brown. Fore wings broad, without the 

 costal fold, but the costal cell slightly hollowed from swelling 

 of the sub-costal nervure ; apex squared ; colour pale smoky 

 yellow without markings; cilia pale yellow. Hind wings 

 broad, smoky brown or smoky white ; cilia white. Female 

 smaller, the abdomen thicker, fore wings more narrow and 

 pointed, clearer pale yellow. Hind wings smoky white. 



Underside of the fore wings smoky black, faintly margined 

 with pale yellow ; hind wings white. 



Variable in the shade of colour of the fore wings from clear 

 pale yellow to various shades of smokiness, and in the North 

 of Ireland showing ochreous tints. The female varies in size. 



On the wing from the end of June till August. 



Larva cylindrical, active, three-fourths of an inch long ; 

 smoky black ; spots conspicuous, large and prominent, pure 

 white ; head and both plates jet black ; collar of the second 

 segment white. 



May and June on Centmirca nigra, Plantojjo lanccolata, 

 bramble, golden rod, coltsfoot, and other herbaceous plants, 

 rolling up the leaves into tubes. It is said that the female 

 larvEe feed on into July. Abroad it is reported to feed on 

 very numerous herbaceous plants, and also on shrubs and 

 trees. 



The moth hides among coarse herbage, in rough pastures 

 and on railway embankments, and in the afternoon may be 

 disturbed therefrom by walking about. At about 7 p.m. it 

 flies of its own accord, gently but freely. Apparently pretty 

 generally distributed upon the coast, but more local inland. 

 Recorded in Kent, Sussex, Essex, Middlesex, Herts, Somer- 

 set, Suflblk, Norfolk, Cambs, Leicestershire, Cheshire, Lanca- 

 shire, Yorkshire, Durham, Northumberland, and Cumberland, 

 but I do not know of its occurrence in Wales. In Scotland 

 it is common in the Clyde Valley, Roxburghshire, the Edin- 

 burgh district, Perthshire, and Aberdeen ; and in Ireland
