M The period between each change was about ten days in some spe- 

 cimens, but varied in others between that and shorter periods, probably 

 depending in a great measure upon the quantity of nourishment 

 obtained from the branches with which they were daily supplied. 



" In the third stage, the caterpillar appeared of a bright rufous 

 colour, the black dots or tubercles being larger and more prominent ; 

 but there were no black bands. 



" In the fourth stage the change was still more remarkable, for the 

 caterpillar now appeared of a beautiful apple-green, each tubercle 

 headed with bright orange, except the four which spring from the 

 second and third segments, which are ringed with black, and crowned 

 with pale yellow ; and the anal and two posterior tubercles, which are 

 green throughout. From each tubercle springs a small tuft of hair, 

 the centre one of each being longer than- the others ; the head and 

 pro-legs brown ; along each side is a line which is red above and 

 yellow below, and the spiracles are red ; there is a line of very small 

 yellow dots along each side between the rows of tubercles. 



" In the fifth stage the colours are the same, as they are also in 

 the sixth and seventh stages ; but the caterpillar increases rapidly in 

 size, and is most beautiful and delicate in appearance, with a semi- 

 transparency of hue which makes it look something like waxwork. 



" One of these commenced spinning its cocoon on the 17th of July, 

 being then about forty-six or forty-seven days old, and the remainder 

 after the interval of a day or two ; that is, on the 19th, 20th, and 25th 

 July. The cocoon is formed of coarse brown silken threads, closely 

 interwoven, and of an ovate form ; it is inclosed among the leaves of 

 the tree, which are, in fact, glued closely round it. It is hard, and 

 not furnished interiorly with a soft silken bed, the chrysalis lying 

 within a hard and hollow chamber. 



" The chrysalis remained thus until the 14th August, when the one 

 which had turned on the 17th July produced a perfect female, after a 

 period of twenty-nine days. Another, which had turned on the 19th 

 July, came forth a male on the 16th August, showing the time to be 

 pretty uniform. A large caterpillar, however, which I found in the 

 forest on the 16th July, turned to a chrysalis on the 24th of that 

 month ; but, instead of coming forth in the autumn, it remained in 

 the chrysalis state throughout the winter — as did some others, — 

 coming out in the following summer ; namely, on the 11th, 14tb, and 

 18th of June. 



" The caterpillar feeds upon several trees common on these hills. 

 The most common food appears to be the Munsooree, a shrub which
