by the broad subdorsal velvety-black stripe, on which 

 the larger orange tubercles encroach. It has a very 

 broken thread of yellow dots along the middle, and is 

 margined below with a fine line of yellow, with another 

 more interrupted beneath it ; thence the ground colours 

 of the side are dark reddish-grey, paler yellowish-grey 

 nearer to the spiracular region, and darker brownish- 

 grey below, including the semi-transparent ventral and 

 anal prolegs with their brown hooks. The spiracular 

 region is edged above and below at the segmental 

 divisions with pale yellow ; all the lateral tubercles are 

 longitudinally oval and dark brownish- grey, each of 

 the uppermost ones placed on a blackish crescentic 

 blotch delicately edged with pale yellow; the belly 

 dark greenish-grey, with a yellowish interrupted stripe 

 on each side close to the prolegs ; the hairs which hide 

 the spiracles are chiefly grey, or slightly mixed with a 

 few black ones on the sides, but those proceeding from 

 the few dorsal black tubercles are blackish, and all are 

 glossy. In one larva the lowest hairs along the sides 

 were whity-brown, the next row above grey, and the 

 upper rows darker grey mixed with black. 



The pupal change, in one instance, occurred on the 

 fourth day after the commencement of the cocoon, 

 which was spun against the side of its cage, and in 

 junction with the leno cover of it, and was formed of 

 a large gossamer web of a roundish figure, about two 

 by one and a half inches, of a darkish grey colour, and 

 having the larval hairs interwoven ; inside this outer 

 web was a hammock of a finer-textured silk, held in 

 suspension by fine threads at intervals in connection 

 with the outer fabric. The pupa within the hammock 

 lay belly upwards, and was eight lines in length, two 

 and a half lines broad, almost uniform in size through- 

 out, the head rounded, and only the last two segments 

 tapered to the blunt and rounded tip ; the surface 

 smooth, quite black, and highly polished ; the old 

 larval skin lying detached behind it. (W. B., 7, 2, 74;
