tered small black tubercles bearing long black seta; (no sign of white tubercles) ; 

 vertex of each lobe produced into a short, thick, cephalic horn, about two-thirds as 

 long as the face, of a transparent testaceous-yellow colour, and irregularly set with 

 comparatively largo setigerous tubercles. Second segment has on cither side of 

 central lino a collection of four small pale conical tubercles, each bearing a long seta, 

 and around their bases are six or seven short setae ; a much larger, white, conical, 

 subdorsal tubercle, with one apical and three lateral black setae ; two minute uni- 

 setigerous tubercles placed below and in front of spiracle ; above leg a conical 

 tubercle, with an apical and three lateral setse. On the third and fourth segments 

 the dorsal tubercles are very stout, and their apices are produced into a short 

 central projection, bearing a long black seta, surrounded by a whorl of five or six 

 similar projections ; the subdorsal tubercle is similar but smaller, and below it is 

 one above the leg like that on second segment. The abdominal segments have 

 similar dorsal, subdorsal, lateral tubercles, the irregularly placed second tubercle of 

 the first stage having disappeared ; and the eleventh and twelfth have the additional 

 central tubercle as in the mature larva. The colouring is very similar to that of the 

 first stage, being greenish- or yellowish-white, with the small, ill-defined, lateral 

 patches, but these are now joined by a narrow broken brown line running just above 

 the subdorsal tubercles. The white shagreen tubercles are absent, but short black 

 setse are very sparsely distributed over the surface, more particularly round the 

 bases of the tubercles. The dorsal tubercles on segments 4, 7, and 11 are brownish, 

 the remainder whitish. 



Third stage. — The structure of the body spines and cephalic horns is practically 

 identical with that in the mature larva, the latter being much longer than in the 

 second stage, viz., one and half times the length of the face. The head is still 

 entirely black, but a few white tubercles make their appearance, and the cephalic 

 horns are entirely black. The ground colour of the body is of a much more pro- 

 nounced greenish or yellowish tinge, thus showing up the paler central stripe, which 

 is divided by a narrow, slightly darker, line. The dark lateral patches of the earlier 

 stages are here scarcely distinguishable, the pigment apparently having concentrated 

 in the dorsal and subdorsal spine stems, which are almost black on all the segments, 

 except 6, 9, 10, and 13, on which they are whitish, but with the greater part of 

 their apical spikes black. 



The remaining are so similar to the full-grown larva as to need no detailed 

 description.
