BREPHOS NOTHA. 99 



length, not very stout, cylindrical, and diminishes so 

 very slightly towards the extremities, that it appears 

 of uniform bulk throughout; the head is full and 

 rounded ; the two front pairs of ventral legs are much 

 less developed than the next two pairs, and the hind- 

 most pair are splayed laterally ; beneath the anal flap 

 is a small point, with a tubercle on each side of it ; 

 the segments are plump and well-defined ; the mode 

 of progression is an undulating, half-looping, quick 

 walk, changed to what may be called a run when the 

 larva is exposed to light. 



The ground-colour is now of a pale subdued tint of 

 green, or else a bright velvety yellowish-green, the 

 dorsal vessel rather a deeper tint of the same, edged 

 with fine lines of pale greenish-yellow ; the subdorsal 

 fine line is yellow, and between it and the spiracles 

 runs another such fine line. The side being now more 

 or less black is, by this pale line, divided into two 

 broad black stripes, which in some specimens are 

 complete, in others only partly so ; the spiracles are 

 white, outlined delicately with black, and beneath 

 them is a broadish stripe of pale yellow or whitish- 

 yellow ; the belly and legs paler green than the back ; 

 in one individual a short, tapering, black streak issued 

 at the end of each segment for half its length forwards 

 as an edge to the subdorsal line, but these streaks 

 began on the twelfth and ceased at the fifth segment. 

 The black marks on the head and second segment 

 appear to be constant, and characteristic of this 

 species ; they may be more minutely described as 

 follows : — a broad irregular blotch down the front of 

 each lobe, forked at the side, and a round spot on the 

 face between them, and two pairs (sometimes more) 

 of black dots on the second segment ; the pale lines 

 of the back are absent from the second segment and 

 from the anal flap ; the anterior legs generally dotted 

 with black. One of Mr. Jeffrey's larvas furnished a 

 good variety ; its colour was a dingy, rather olive- 

 brown, with the lines of a pale pinkish-grey, with
