ARCTIID.-E. 243 



black ; each segment crossed by an orange bar in which the 

 black raised spots are conspicuous ; dorsal line whitish ; 

 spiracular stripe white, sometimes branching out on the 

 upper side ; on the back of each segment, near the dorsal 

 line, are two white dots. Very variable in depth of the 

 general colour and in the distinctness of the markings. 

 When younger the bristles are fewer and the orange bars or 

 spots brighter. 



On Myosotis ixdustris, M. versicolor, and probably other 

 species of Forget-me-not; also Borago officinalis, Mirabilis 

 jakvpa, Hcliotropmm Uicropccnm, and Solanum tomcntosmn. 

 Feeding on the leaves, mainly in the sunshine — indeed so 

 dependent upon sunshine that in dull wet weather it refuses 

 to feed at all. From this cause I lost all but one of a 

 promising young family of larvae (of French parentage, the 

 eggs from which the previous brood had been reared having 

 been sent to Mr. Tugwell, from Mentone, by the late 

 Mr. Sidebotham). These were eagerly feeding upon 

 Myosotis in a sunny window, and one had become full grown 

 and had spun up, when a week of wet weather supervened, 

 and the remaining larvas refused to eat, or even to move, and 

 all died, the single spuu-up individual alone reaching the imago 

 state. July — but doubtless in two broods, or more, wherever 

 it can permanently exist — the first brood, after (probably) 

 hybernating young, feeding up in May. 



Pupa short, abdomen rather thick and blunt behind ; 

 glossy orange-brown, with the eye-cases and edges of the 

 wing-cases blackish, and dark-brown transverse lines on the 

 backs of the abdominal segments. In a very slight silken 

 cocoon ; probably on the ground among rubbish. 



The moth is very rare in this country, and perhaps can 

 hardly be called a permanent resident in the sense of 

 regularly perpetuating its species. Its powers of flight are 

 extraordinary considering the delicacy of its structure, and 

 it has been known to fly on board ships hundreds of miles
