line faintly indicated. Hind wings smoky-white, dorsal 

 portion white, apex dark ; a faint indication of a smoky line 

 crosses the middle. Body and legs shining white. 



On the wins' from the end of June till August ; in one 

 generation. 



Larva rather plump, sluggish, very pale green with darker 

 dorsal and subdorsal lines ; head black ; dorsal plate pale 

 green with a black bar at each side ; spiracles and centres of' 

 the raised dots black. 



October till June, on Inula dijsentcrica (fleabane) and 

 /. conyza (ploughman's spikenard), feeding on the young 

 leaves and eating out the heart ; making a chamber by 

 uniting two young leaves together, or when young by turning 

 down the edge of a leaf, and hybernating in such turned- 

 dosvn portions. 



Pupa slender, the wing- and leg-covers rather long and 

 projecting a little in front, their surfaces rather dull but 

 quite smooth and without sculpture; dorsal surface also dull 

 and almost without punctures ; abdominal segments more 

 glossy and very smooth ; cremaster rather long and projecting^ 

 spud-shaped, tipped with minute curled bristles ; whole 

 surface deep pitchy-brown except the interstices of segments; 

 and edges of wing-covers, which are ^jaler. In a loose 

 cocoon between leaves upon its food-plant. The transforma- 

 tions in this species are not retarded. 



The moth sits constantly upon its food-plant during the 

 day, resting on the underside of a leaf, on a leaf-stalk, or 

 anywhere upon the beloved plant, hanging back by its slender 

 legs as though on tiptoe. If disturbed it readily flies, but 

 only to a short distance, to another plant, but is not much 

 inclined to conceal itself near the ground. At early dusk it

 England, wherever its food-plants are found, but apparently-
