112 LEPIDOPTERA. 



mining down, then piercing the flower-stem and feeding upon 

 the pith, working its way downward and becoming full-fed 

 in the thickened bulbous base of the flower-stem. (Dr. 

 Knaggs.) 



Pupa in the larval habitation. 



The moth doubtless hides during the day among dead 

 grass-blades on, or close to, the ground. At from 8 till 

 9 o'clock P.M. it flies swiftly about the masses of its 

 favourite grass, Fcstuca arundinacea, where it grows in 

 abundance upon steep slopes of hills and clifEs, mainly upon 

 the "green-sand" formation, and forms immense tnfts. 

 After 9 p.m. the moth settles down and sits conspicuously 

 upon the grass, from which it may readily be collected by 

 the aid of a lantern. After 11 p.m. it again flies, and will 

 then sometimes come to sugar. Excessively local, and with 

 us, so far as is known, confined to the South Coast. First 

 taken at Folkestone, Kent, in the year 1859 by Dr. H. G. 

 Knaggs, and afterwards named by him in honour of the late 

 Mr. F. Bond. Still fairly abundant in the same locality, 

 which is not very easy of access ; and more recently found 

 in plenty near Charmouth and Lyme Regis, and thence 

 towards Sidmouth, in the counties of Dorset and Devon. 

 With the exception of a single specimen picked up by Mrs. 

 N. M. Kichardson at the Isle of Portland, this appears to be 

 the extent of its range in these Islands. Abroad its only 

 known localities are, so far as can be ascertained, the Island 

 of Riigen, Germany ; and Mount Parnassus, Greece.
