330 DEPKESSARIA BADIELLA. 



At this time they were nearly 5 mm. long, cylindrical, 

 of a cinnamon-brown colour, with shining darker dots, 

 a blackish-brown frontal plate and anal plate. 



By the 2nd of June, one of these had added 1 mm. 

 to its length and seemed to have moulted, the 

 cinnamon-brown being rather darker than before ; 

 the tubercular dots on the back were nearly in a line 

 and darker brown than the body; the plate on the 

 second segment is glossy black, the head darker 

 brown than the body, the anal plate shining black, 

 and there is a transverse narrow black plate on the 

 dorsal portion of the front of the anal segment. 



These larvae live in fine white silken webs between 

 two leaves, or under one leaf, which is spun fast upon 

 some firm substance; they live in this way concealed, 

 though by their feeding on the lower cuticle of the 

 leaf a transparent blotch becomes visible, and they 

 push out from their dwellings little heaps of blackish 

 excrement. 



By the 7th of June the most advanced had reached 

 the length of 8 mm. ; on the 16th I figured one of 

 them, but minus the blackish tubercular dots, which 

 are at this stage more trapezoidally arranged on the 

 back ; a black shield was outside the anal legs. 



On the 11 th of July I received more of these larvae 

 from Mr. Fletcher, one of them grown to be 20 mm. 

 long; it was of a dark red colour, greenish when the 

 segmental divisions were stretched ; the dots were 

 black, ringed with greenish; the black plate on the 

 second segment is divided in the centre, and with 

 paler yellowish margin of skin in front ; the anal 

 plate is black and a small black transverse oblong is 

 on the front part of that segment. The head is dark 

 reddish-brown ; the anterior legs are black ; all the 

 dark red skin is dull, the greenish divisions glistening 

 a little, the black dots, head and plates glossy, a fine 

 hair arising from each dot. 



These five later larvae were put with three vigorous 

 growing plants on the 16th, and by the 23rd every
