Larva. — The larva is spined like that of the last species but has the head 

 without horns and quite smooth ; the colour is oily brownish-purple with 

 black spines. Head dark brown-yellow, with a still darker brown clypeus, 

 centred at base by a white triangle ; a large oblique black spot at base of 

 each lobe over eyes reaching half way up face in some specimens ; the shape 

 is that of a heart, the broadest side being the vertex. The body is cylindri- 

 cal, slightly constricted at segment margins ; anal end perpendicular to 

 longitudinal axis of larva, rather high ; the head is somewhat broader than 

 segment 2, nearly as broad as the body is in middle at segment 7, which 

 is the broadest part of the larva. Spiracles black, bordered narrowly with 

 white, oval. Surface oily-shiny, with the following spines, themselves set 

 with fine setse : segment 2 with one subdorsal, a lateral one on segment 

 margin 2/3 ; segment 3 with one subdorsal and one on segment margin 3/4 ; 

 segment 4 one subdorsal ; segments 5 to 12 have each a subdorsal, lateral 

 (might be called supraspiracular) and subspriracular; the 13th has a subdorsal 

 spine and segment 14 a lateral one on margin towards middle of segment. 

 All the spines are of nearly equal length, not as long as the body is broad 

 in the middle. The colour of the body is purple-brown, oily looking, with 

 a subspiracular waved white line ; belly reddish-brown, spines and their 

 setae shiny black rising from black tubercles, except the subspiracular 

 ones which are whitish and rise from yellow-brown tubercles. L : 30 mm. 

 B : 5 mm. 



Pupa. — The pupa is of more or less ordinary shape, bright green, marked 

 with black, rose-crimson and mother-of-pearl. The head is square with 

 two minutely black-tipped, conical tubercles, one on each eye, directed 

 straight forwards ; the eyes bordered with red in front. Segment 2 is 

 flattish on top ; thorax is rather square seen from above, convex ; shoulders 

 angled ; constriction at segment 5 dorsally little, laterally wide and shal- 

 low. Wings expanded latterally slightly from just behind shoulders to 

 segment 6. Abdomen stout, curving at end, so that the last segments 

 have their axis nearly at right angles to the longitudinal axis of the pupa. 

 Cremaster compressed laterally, the extremity being longer than broad, 

 and set with suspensory hooklets, so that the pupa hangs horizontal to the 

 surface to which it is fixed. Spiracles of ordinary size, oval, slightly raised. 

 Surface shiny, smooth except for a pair of small, conical, sharp tubercles 

 to each segment, subdorsal, one on each side ; they are hardly visible on 

 segments 4, 13, 14 ; small on segments 6, 8, 10, 12 ; larger on segments 

 7, 9, 11 ; those on segment 2 are also small ; on thorax there is an addi- 

 tional lateral one. The colour is a bright, clear, grass-green ; all the 

 tubercles are mother-of-pearl, tipped with black and rose-crimson ; the 

 wings have one long mark along the inner margin, mother-of-pearl bordered 

 with rose-crimson, reaching from shoulder to near the tornal angle, and 

 another, similar, reaching from just behind shoulder to half way towards
