16. P. fuligana, H\ib.; ustulana, Hmr. — Expanse \ to 

 j; inch (12-l.j mm.). Fore wings short, ovate, black-brown ; 

 central band dull black much notched at the margins, but 

 obscure. 



Antennas, palpi, head, and thorax dull black ; abdomen 

 brownish black. Fore wings narrowl}^ ovate, costa gently 

 arched, apex bluntly rounded, hind margin a little curved ; 

 brown-black, the central band deeper black and much 

 notched at the margins yet obscure ; costa dotted with 

 deep black, apical area filled with fine streaks of the same ; 

 but in some examples this outer area is mottled with tawny 

 and pale grey ; cilia black mised with grey. Hind wings 

 and their cilia dark smoky brown. Female similar, but 

 rather larger, the faint markings often more distinct. 



Undersides of all the wings dark leaden brown. 



When perfectly fine this species has a scorched appearance 

 from a delicate marbling of obscure chestnut scales. 



Ou the wing in -June and July. 



Larva dirty white, tinged with yellowish green. 



September to Maj- iu Ajiuja orptans (common bugle), 

 feeding at first in the rootstock just above the surface of the 

 ground and afterwards mining up the stalks of the leaves. 

 In plants that are protected by furze bushes or in some 

 similar manner. (Mr. G. W. Bird.) 



Pupa either in the empty mine, or outside among the 

 leaves of the food-plant. The moths emerged in the middle 

 of June. (/'/.) 



The moth is attached to railway embankments, and the 

 dry banks on vv'hich the bugle grows. Its flight is quick when 

 disturbed from the low-growing herbage which it frequents, 

 and its wings are so dark that it becomes difficult to see upon 

 the wing. From this cause it may be somewhat overlooked, 

 but it is known to occur in Kent, Surrey, Sussex, Dorset, 

 Wilts, Berks, Oxfordshire, Essex, Sufiblk, Norfolk, Hants,
