148 LEPIDOPTERA. 



tudinal stripes, a dark dorsal, a dark (but less dark) lower 

 one and a pale intermediate. In all these the ground colour 

 is the same nankeen-yellow, and the darker areas depend on 

 the greater or less darkness of fine black mottlings, generally 

 in fine wavy streaks running more or less longitudinally. 

 The dorsal dark stripe is darker on each of its margins, and 

 each margin is darker toward the incisions ; the pale stripe 

 is somewhat darker centrally, whilst the lower stripe again 

 is darker marginally and toward the incisions, but only in a 

 degree which requires looking for, instead of being obvious 

 as in the dorsal stripe. The spiracular region is paler, almost 

 amounting to a pale spiracular stripe, and the undersurface 

 is nankeen-yellow with a slight fuscous tendency. The 

 second segment is of a more uniform tint and the pale dorsal 

 line extends distinctly through it and on to the head, which 

 is rather brown than yellow, mottled in a honeycomb 

 pattern ; there is also some black marking about the labrum 

 and jaws. In some lights the whole larva has a pearly lustre, 

 or perhaps a bloom like that on a plum would best express 

 the effect. Each segment has four or five transverse in- 

 cisions. The ordinary tubercles are marked by very fine 

 nearly transparent brown bristles, of which there are also 

 some on the head. The segments taper slightly toward the 

 head, more rapidly toward the anal extremity." (Dr. T. A. 

 Chapman.) 



Mr. Buckler says that the head of the infant larva is 

 brown marked with black, the body drab at intervals, with 

 smoky dark grey on the anterior segments and some of the 

 others, the raised dots shining black, each with a black hair. 

 After a few days the general colour becomes green, the head 

 much marked with brown on the lobes, and the second 

 segment showing a divided brown plate. After the first 

 moult green, with darker green subdorsal lines, and a lateral 

 line closely followed by a whitish spiracular stripe ; head and 

 dorsal plate dotted with black. After the second moult the 

 head is shining pale green with four rather large black dots
