evening deposited 84 eggs ; and on the following evenings she again 

 deposited as follows : — On the 15th, 38 eggs ; on the 16th, 21 ; on 

 the 17th, 16 ; on the 18th, 21 ; on the 19th, 14 ; on the 20th, 14 ; 

 and on the 21st, 7; amounting in all to 246 eggs, and she then 

 died. 



" On the 28th April I received a male and female from the same 

 place ; and in the evening the female deposited 89 eggs, and con- 

 tinued each night to increase the number until she had deposited 

 300 eggs, when she died. 



" On the 30th April, or eighteen days from the time of deposition, 

 the first batch of eggs began to hatch ; the newly born larva is about 

 3 lines in length, hairy, and of a pale rufous-red, with a single black 

 band across the middle of the body, and a small black transverse 

 mark on the anterior segment ; along the back are two rows of small 

 tubercles, and another along each side, from each of which spring a 

 few short hairs, the base of which forms a small black dot ; there is 

 also an anal tubercle, larger than the others, and placed between the 

 two last tubercles of the dorsal rows ; the head is black. I was now 

 exceedingly puzzled to find out the proper food, and, having unsuc- 

 cessfully tried several kinds, at last gave them the leaves of our com- 

 mon hill oak (an Ilex), of which they ate sparingly and without ap- 

 petite. This was evidently not the proper food ; and although they 

 continued to eat it they did not thrive, but died in such numbers, that 

 I had at last only five larvee left out of 546, and even these I was in 

 daily expectation of losing ; when, by a lucky chance, on the 30th of 

 June, I discovered a single larva in the forest feeding on a tree known 

 to the natives as the ' Munsooree ' ( Coriaria nipalensis) . Branches 

 of this tree were now substituted for the oak, and from thenceforward 

 the larvse ate greedily and increased rapidly in size. The^r*^ moult 

 commenced when six days old, and this occupied three days, so that 

 at the end of nine days the larva appeared in its second stage. The 

 black transverse band upon the body had disappeared, but the head 

 still remained of that colour, and the rest of the body was hairy and 

 rufous; the tubercles being black on the summit and more promi- 

 nent ; pro-legs brown. 



" The period between each change was about ten days in some 

 specimens, but varied in others between that and shorter periods. 



" 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 beauti- 

 ful 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 of each being longer 

 than the others ; the head and prolegs 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
