4 CYMATOPHORA OCULARIS. 



ings of white silk ; in this retreat, when not feeding, 

 the larva reposes with its body curved round— and 

 here also, when the time for a moult approaches, it lies 

 in a close coil, its head resting on the middle of one 

 side of the body. 



Particularly noticing a larva, which moulted on 

 June 27th, I observed the body to be very soft and 

 delicate, velvety in appearance, of a pale buff tint ; the 

 head pale honey-yellow, rather glistening, with black 

 ocelli, and black on each side of the mouth ; two black 

 dots, one above the other, on the side of the second 

 and third segments, and one on the fourth, another 

 also on the twelfth segment. After the last moult, 

 when the larvae measured fully an inch in length, their 

 heads were pale brownish-orange, broadly marked with 

 black at the sides of the mouth and round the papillae, 

 the skin of the body still soft in texture, without the 

 least gloss excepting a narrow shining plate behind the 

 head, which is slightly glistening, and the anal flap 

 and legs ; the colour of the body delicate greyish- 

 green, showing through a pale buff skin, the dorsal 

 vessel seen pulsating distinctly, the spiracles flesh- 

 colour, and the colouring along their region pale yel- 

 lowish, the black dots just as before. 



By the 4th of July two larvae had spun up, the two 

 others were still feeding, the rest having died off one 

 at a time at different stages, probably from being so 

 often interrupted by my investigations. Even at the 

 last, when mature, the habit of the larva is still to lie 

 curled round, with its head inwards, and towards, or 

 in contact with, the seventh or eighth segment of its 

 body. I found also that when turned out from its 

 domicile between two leaves, the larva, when placed 

 on a fresh leaf and another laid over, would quickly 

 spin new fastenings, but it was not easy to watch its 

 proceedings, for, when I raised the upper leaf but a 

 very little in order to peep, the larva would directly 

 strengthen and shorten the silk stud that I had prob- 

 ably stretched,, and it did so by taking the middle or
