ridge ; besides all this marking there is, on each side of segments 8 and 

 9, a broad, thinly white-bordered, thickly white-sprinkled band, limited 

 anteriorly by the white border reaching, from the front margin of segment 

 8 at the subspiraciilar white band, up and backwards, crossing the common 

 segment margin 8/9 in the dorsolateral region to meet the posterior 

 limiting line in a curve svibdorsally (the bands on either side therefore 

 do not meet over back), this posterior boundary then running down, 

 parallel to the anterior one, to the subspiracular band at posterior margin 

 of segment 8 ; on segment 10 there is a similar white-sprinkled area occupy- 

 ing the spiracular region on each side, triangular in shape, bordered in 

 front by a white line starting from the front margin at subspiracular band 

 and running back to hinder margin in the lateral region, below by the sub- 

 spiracular line, and behind by the hinder margin of segment ; the front 

 margin of segment 2 is yellowish white ; true legs are green ; the prolegs 

 also greenish with two transverse dirty lines; the anal claspers are whitish; 

 venter light-green. The osmateria or scent-organs are flesh-coloured. In 

 some larvse there may be a small subdorsal tubercle in middle of segment 

 12. There is generally a small blue subdorsal spot near the hinder margins 

 of segments 9, 10 ; on the former in the band and another below ; on the 

 latter segment the place ef the blue spot may be taken by a triangular 

 small white patch blotched with blackish ; there may be a whitish dot 

 ' dorsally on segment 4 and a lightish one subdorsally on segment 5. L :

Bwpa. — The pupa is bent back from about the middle so that the longi- 

 tudinal axis of the one-half is at an angle of about 80° with that of the 

 other half ; the wings ventrally describe a prominent curve along their line 

 of junction and the ends of this curve run straight and evenly to the 

 points of the head forward and the cremastral end backwards ; the dorsal 

 outline is correspondingly concave in the middle but convex again in seg- 

 ments 8 and 9, with segment 7 gradually sloping up to 8 from the bottom 

 of the curve, segments 6 and 5 forming the lowest part of it, segment '4 

 sloping up again towards thorax and, with the hinder half of thorax- 

 length, in a straight line as far as the thoracic apex, whence the front half 

 of the thorax falls suddenly at an angle of about 100° to the hinder slope 

 in a slight curve to its front margin, after which segment 2 is nearly paral- 

 lel, although slightly concave, to the longitudinal axis of pupa at that 

 point. In lateral outline segment 2 is nearly parallel-sided and in con- 

 tinuation with the exterior margins of the head-points, but gets very 

 slightly broader backwards ; the shoulders are somewhat suddenly promi- 

 nent, after which the pupa is again parallel-sided as far as the constriction 

 where the body-loop passes ; after this the wings (and body) are expanded 

 as far as middle of segment 7, the greatest breadth there culminating in a 

 low rounded point ; then the breadth again diminishes rapidly to hinder
