but of varying lengths, blackish-plumed and clubbed at 

 their tips. 



By the 27th three or four had accomplished their 

 fourth moult, with tufts of quite white hairs down their 

 back ; they were then three-quarters of an inch long. 



By the 19th of August they were full-grown, and 

 1| inches in length ; the white brush-like hairs on 

 the back tipped with brownish, the black hairs plumed 

 and clubbed as before on each side of the second 

 segment, and on the back of the twelfth ; cream- 

 coloured hairs radiated from the other tubercles, longer 

 and more numerous on the lower rows along the sides ; 

 ground colour of the body cool velvety-grey, a black 

 velvet stripe down the back, more or less interrupted 

 by the brushes and by brilliant red tubercles, a black 

 or blackish line followed on each side more or less 

 distinct or broken ; head shining black, upper lip pale 

 creamy-white, mouth black ; on segments 9, 10, 11 and 

 12 the black dorsal stripe was bordered with cream 

 colour as a narrow stripe. 



In some individuals the ground colour was greyish- 

 olive, and the red tubercles were outlined with cream 

 colour. 



All the above died off nearly mature. 



I received some more eggs on the 9th April, 1 880 ; 

 they began to hatch May 14th.* I fed the young 

 larvae with sallow. The first moult took place the 18th 

 and 19th of May. These larvae throve well on sallow, 

 and the earliest began to spin their cocoons on the 

 17th and 18th of June. The moths began to appear 

 on July 10th, when I bred two <? and two ? ; on the 

 13th appeared three S and on the 17th one S • (W. 

 B., Note Book IV, 1.) 



* The larvse continued to Latch about two a day, sometimes three, 

 but generally two until the 29th May, when there were twenty-one 

 hatched, and I cast adrift the remaining eggs.
