black, the deep yellow lateral spots enlivening the 

 general darkness. 



Towards the end of June and beginning of July it 

 has reached its blackest stage, for it is then intensely 

 and beautifully black, which gives additional brilliancy 

 by force of contrast to the light greenish-yellow lateral 

 spots ; the head is black and shiniug, the second seg- 

 ment green and smooth in front, the segmental divisions 

 when stretched out show greenish and glisten a little, 

 but all the rest of the upper surface is thickly covered 

 with black hairs. 



The full-grown larva is from 7 to 8 lines in 

 length, sometimes more, and nearly 3 in breadth, 

 of elliptical figure, but with the head small and retrac- 

 tile within the second segment ; and this also being in 

 part retractile is twice as long as any of the others and 

 tapering in front ; the anal segment is slightly tapered 

 and rounded off behind ; all the segments are plump 

 and cut extremely deep ; the head is black and glossy, 

 with green upper lip edged with black, the antennal 

 papillae whitish tipped with black ; the front retractile 

 half of the second segment is green and naked, the 

 other half and likewise all the other segments of the 

 body have the ground colour of the back and sides 

 very dark green, along each side is a broken velvety- 

 black stripe interrupted at the end of each segment 

 beyond the second or third by a bright yellow elliptical 

 transverse spot ; each segment bears a series of ovate 

 tubercular eminences thickly studded with short black 

 radiating bristles, and a single long and fine hair. 

 These almost or quite hide the green ground of the 

 upper surface of the skin ; the spiracles are black, the 

 smooth naked belly is of a green rather less dark than 

 that of the back ; the anterior legs are black and 

 shining with light green joints on the outer side, and 

 light green inner surface ; the ventral and anal prolegs 

 are of a lighter green than that of the belly and semi- 

 transparent. 



The cocoon is about 7 or 8 lines in length, and from
