of the second segment and the anal flap ; the colour 

 of the body, i. e. the back and belly, was very dark 

 slaty-grey, the dorsal stripe and the spiracular stripe 

 of bright pale yellow as before ; the lobes of the head 

 had each a large black spot on the crown ; the ocelli 

 in a black spot below, the face and lip greyish-white, 

 also papillae tipped with black, edge of lip black ; the 

 second segment pale yellow across the middle with 

 two pairs of black spots in front and again at the back ; 

 the ridge on the third segment was bright yellow, 

 bearing two black tubercles, that on the twelfth seg- 

 ment also yellow, bearing four black tubercles in pairs ; 

 all the tubercles were velvety-black and bristly; the 

 dorsal ones on the third and fourth segments bore two 

 long black hairs, but all the others only one black hair ; 

 a black, horny oval spot was on the outer side of each 

 ventral proleg ; anterior legs black. By the 16th of 

 April it had become 9J lines long or 20 mm., and by 

 the 18th was 11 lines or 23 mm. long. 



By the morning of April 25th it had moulted again 

 for the fourth time, and on the 29th measured 1 J inches 

 or 32 mm., stout and cylindrical ; a transverse elevated 

 ridge across the middle of the third and twelfth seg- 

 ments of bright pale yellow ; the dorsal yellow stripe 

 was a little interrupted at the end of each segment ; 

 the spiracular stripe was broadish and abruptly con- 

 trasted with the dingy greenish smoky-grey of the 

 belly, but above was softened off a little into the 

 greenish-grey of the side, and this was separated from 

 the very pale bluish -grey of the back by a subdorsal 

 stout line of white, very softly edged and faint. 



By the 6th of May, when stretched out it was 1^ 

 inches long and stout in proportion, the skin smooth 

 (apparently) but without gloss, the black spots round, 

 dull, and rough, each surrounded by a whitish halo. 

 By the 8th it was full-fed, and in a day or two began 

 to contract in length and wander about until the 12th, 

 when in the course of the night it spun itself up within 

 an oval cocoon of whitish silk overlaid with portions
