osraateria are red-orange in colour. There are light-blue spots where 

 the dorsolateral tubercles of last stage were one to each. L : 20mm ; B : 

 nearly 7 mm. when at rest. The larva stretches, when moving, to 2omm'. 

 Last stage. — All tubercles have now disappeared except those on the 

 hinder margin of segment 13, and these even are now reduced to very small, 

 convex, minvitely haired knobs ; they are situated on the green colour of the 

 upper parts of the larva, just above a yellow line along the hinder margin 

 of the segment ; this hinder margin is thickened and is in a plane at right 

 angles to the rest of larva and overhangs the rather large, broad anal flap, 

 which is in a parallel plane to it ; this flap is whitish in colour with a square- 

 cut end. The head is nearly round, slightly higher than bi*oad, with a dull 

 surface covered with minute, semi-appressed white hairs ; the clypeus is of 

 ordinary size, triangular in shape, with a white linear border and rounded 

 apex ; the colour of head is green, the eyes black, the antennse shiny-trans- 

 lucent whitish. Segment 2 is trapeze-shaped, the front margin slightly 

 longer than the sides, the hinder margin longest ; the breadth of body 

 increases rapidly to segment 5/6 where there is a thickening or swelling 

 along the hinder margin of segment 5, not very pronounced, however ; after 

 this it decreases gradually to the square end which is practically between 

 the tubercles on hinder margin of segment 13. The surface of larva is dull, 

 smooth and soft-velvety looking. Spiracles are of ordinary size, flush, oval, 

 body-coloured, with white central slit and fine brown border. The colour 

 of the body is a fine bright grass-green, plentifully speckled with yellow, 

 especially on the hinder margins of segments 6-13 ; with a white, supra- 

 spiracular band from segment 5/6 to anal end ; an indication of a yellow dia- 

 gonal line from front margin of segment 8 back and up through the spiracle 

 to the subdorsal region on the hinder margin ; below which line the speck- 

 ling of yellow is absent ; on the same region of segments 9, 10 the yellow 

 speckles are grouped into patches to some extent, suggesting bands ; the 

 segmental membrane between segments 5, 6 is broadly velvety black, 

 hidden in repose ; there is a fine black, supraspiracular line from just 

 before spiracle of segment 2 running back on to segments 2 and 3, above 

 which the body is white, but only for a short space, then yellowish, losing 

 itself in the green of the dorsal parts ; the white is continued back in a 

 curve over dorsum along the hinder margin of segment 5 (along ridge) 

 and the green of the dorsum in front of this ridge is speckled white 

 forwards for the distance of half the width of segment; the front of 

 segment 2 is yellowish ; there is a long, finely black-bordered area along 

 dorsal line of segment 4, narrow and constricted twice in its length and, 

 on the same segment, a rather small ocellus or eye with a white central 

 dot, just above the supraspiracular white band, contained in the hinder- 

 jnost and lowest loop of a fine black line running, just along the upper 

 border of the white band from the front of segment 3, back to just behind
