PKMPEL1A PALUM BELLA. 283 



dorsal and subdorsal lines darker than the ground 

 colour of brownish-green on the body. One day later 

 I could see just what Mr. Fletcher had imparted to 

 me while mine were hatching, viz. tbat they had spun 

 many fine webs from leaflet to leaflet, which had be- 

 come dotted minutely with frass, and that ling is un- 

 doubtedly their proper food-plant. 



On the 2nd of August they had grown a little, and 

 the head was deep olive-brown marked with black on 

 each lobe; the plate on the second segment was dark 

 shining brown; the body was a subdued olivaceous 

 greenish, with numerous very thin length lines alter- 

 nately paler and darker, the dorsal and subdorsal 

 being darker. 



They bad got over their first moult between the 

 27th and the 31st of July, of which the head-pieces 

 hanging in the webs bore evidence. 



On the 9th of August two or three were almost 

 ready to moult again, and in this condition were 

 rather paler than the rest. Only thirteen were now 

 left alive. 



On the 13th they had moulted the second time, 

 and on the 18th I placed them on a growing plant of 

 heather. 



The larva now is just 5 mm. long and of slender 

 proportion, and is of a deepish heather-green on the 

 back, having a dark blackish dorsal line finely edged 

 with paler like the pale line above the subdorsal line ; 

 this last is a black line followed by a dark blackish- 

 green stripe ; beneath this is a broad stripe of green 

 like the ground of the back, and is edged with a paler 

 line both above and below ; the head is green marked 

 with black on each lobe; the plate is green, having 

 the lines on it, but it is glossy. All now alive were 

 four only. 



On placing them on the plant they began to spin 

 threads uniting the top of the heather spray to a 

 rush which I had cut to the same level. (William 

 Buckler, 19th August, 1883 ; Note Book IV, 204.)
