PTEROPHORID.-E—LEIOPTIL US. 391 



Larva about half an inch in length, head polished, about 

 the same width as the second, but narrower than the third 

 segment, pale yellow ; body rather flattened beneath, and 

 also a little on the back, grass green ; there is an interrupted 

 grey line along each side of the dorsal ridge, and a fj^int 

 indication of a similarly coloured sub-dorsal line; raised dots 

 greyish-white, as also are the hairs ; segmental divisions pale 

 yellow ; ventral surface uniformly grass green. (G. T. 

 Porritt.) 



September till May on SuUclago virgaurca (golden-rod), 

 feeding upon the leaves, in which it eats holes. 



Pupa half an inch long, compact and of moderate bulk ; 

 a distinct depression extends down the dorsal surface from 

 the head to the anal extremity ; abdominal divisions and eye 

 and leg-cases well defined ; colour dingy dull green, the sides 

 thickly sprinkled with smoke colour; and a smoky stripe 

 through the wing-cases : the abundant hairs grey. Not 

 suspended, but lying flat along a leaf or stalk attached only 

 by the anal extremity. (G. T. Porritt.) 



The moth frequents especially the open parts of woods 

 where golden-rod is common, and is easily disturbed from 

 among it and neighbouring herbage in the afternoon. Its 

 natural flight is rather late in the diisk and well into the 

 night. It is known to occur, and sometimes commonly, in 

 such places in Kent, Sussex, Surrey, Berks, Dorset, Devon, 

 Cornwall, Somerset, Essex, and Herefordshire ; and very 

 locally in Derbyshire, Lancashire, Yorkshire and Westmore- 

 land. In Wales I only know of it in woods in Pembroke- 

 shire and at Bangor ; in Scotland in Dumbartonshire, and. 

 curiously enough, in the Isle of Skye ; in Ireland Mr. Kane 

 records it in Clare, Galway, and Sligo. Abroad it is common 

 in Central Europe, also in the more temperate portions of 

 Northern Europe, including Norway, and in Northern Italy, 

 and Southern and Eastern Russia.
