folded, hind margin notched below the apex ; hind wings 

 broad, faintly ridged. 



We have two species, of which L. saUirnana has fore wings, 

 decidedly broader than those of L.^phimhana. 



1. L. plumbana, aSVo^:). ; ulicana, IFilk., Stn. — Expanse 

 1 to f inch (12-15 mm.). Rather stout; fore wings not 

 folded, rather narrow, olive brown dusted with yellow scales ; 

 dorsal blotch faintly paler. 



AntennfB black-browa ; palpi, head, thorax and abdomen 

 dull bi'own. Fore wings rather narrow, costa without fold, 

 and very little arched ; apex blunt, hind margin a little 

 oblique ; dark brown thinly dusted, especially in the hinder 

 area, with yellow brown ; dorsal blotch usually perceptible 

 dull faint yellowish brown, rounded above and but little 

 oblique; costal dots minute, alternately black and yellow 

 brown ; before the hind margin are two or three deep black 

 round dots. The usual leaden lines extremely faint ; cilia 

 shining dark brown. Female similar, but often much 

 darker, also stouter. 



Undersides of all the wings shining lead colour ; costal 

 dots of the fore wings dull white. 



End of May till August, possibly in two generations. 



Larva of nearly uniform bulk, opaque, yellowish white ; 

 becoming somewhat transparent just before spinning up ; 

 head amber-colour ; mouth black ; plates and legs ochreous ; 

 raised dots inconspicuons. 



March and April on Chrysanthemum leucanthemum , feeding 

 low down in the roots, grooving them deeply under cover of

 root-stocks. Also feeding, probably as a second generation, 

 in August, in stems of Achillea millefolium, feeding down- 

 ward toward the root-stock. (Dr. J. W. Wood.)

 not apparently especially fond of sunshine, moving about, if
