NEW PLUME-MOTH. 



27 



When crawling on to a Drosera plant the larva seems very careful 

 to keep clear of the gummy petioles, and is assisted to do so by 

 its long hairs, more especially those situated upon the head, for 

 these hairs are seen to have enlarged basal attachments, which are 

 evidently correlated with hypertrophied tactile nerves. (See fig. 5). 



When crawling over the leaves the gum is often seen to adhere to 

 the legs of the larva, which then stops, bends down its head, 

 and cleans them by passing the gummy legs through its mouth. 

 The whole process rather reminds one of a cat licking itself clean.

Pupation. — When searching for the larvae I must have examined 

 several scores of Drosera plants, which either contained full-fed larvae 

 or showed signs of having recently done so, but only in one case have 

 I as yet found the pupa in a natural position, and, judging by the 

 restless behaviour of larvse in confinement just prior to pupation, 

 I am constrained to believe that the larva wanders away from the 

 plant and fixes itself up for pupation on some grass stem or other 

 similar object, where its discovery would be rendered exceedingly 

 difficult by its resemblance to a pendulous grass seed. 



This pupa, which was found in situ in its natural position (on 27th 

 August), was on a medium-sized Drosera plant, which was growing
