THE ENTOMOLOGIST. 21 



I accidentally found a company of more than twenty similar 

 little larvae on two other leaves of the same tree, at about the 

 same height from the ground. These resembled in all 

 respects our fig. 3; and the petioles of the leaves, on which they 

 were, had precisely similar scars of eggs, so that 1 had no 

 doubt the species was the same. I left the larvae alone until 

 they had changed their skin once, when I took ten of them 

 in-doors; and on the 1st of October made a drawing in 

 outline of six on a leaf, to show their manner of feeding, and 

 the position they assume (fig. 4). I also made a coloured 

 drawing of one, magnified (fig. 5). 



On the 10th of October they appeared to be nearly full 

 grown, when 1 made a coloured drawing of one of the 

 natural size (fig. 6). The head was shining black, more or 

 less brown towards the mandibles ; antennae, palpi and 

 labium pale brown ; on the vertex were some short hairs. 

 The 1st segment of the abdon)en, together with the lower 

 part of the anterior legs, was sordid orange ; the spiracle on 

 that segment was elliptical ; the anterior legs were, for the 

 remainder, of a dull greenish white, the claws being pale 

 brown ; just in advance of the leg was a black spot of the 

 shape of an extended letter V. From the Snd to the last 

 segment the back was yellowish gray-green ; at the side, 

 above the spiracles, vvas a bluish black longitudinal stripe, 

 very faintly toothed above and below. In the gray-green or 

 yellow of the dorsum, each segment had two rows of minute 

 tubercles, the first row consisting of two, the second of four; 

 from each of these little eminences proceeded an aluiost 

 invisible hair. Below the black lateral stripe, and on the 

 ventral surface, the colour of the skin is a very pale gray- 

 green, the same tint being also observed on the middle legs ; 

 above the legs are two narrow black bands, which are inter- 

 rupted at short intervals, thus consisting of a series of little 

 lines; these extend to the 11th segment. I do not remember 

 to have counted more than twenty legs on the full grown 

 larvae, nor do I find any note to that effect. There must 

 thus be a great difference in this respect between the present 

 and the preceding species (Dineura Alni), which, added to 

 the wholly different habit, is the more striking, seeing that 

 the insects in the perfect state differ so \ery little from each 

 other.
