looking, and of a deep reddish-grey colour ; the head 

 shining black, the anterior legs glossy, tipped with 

 black, the ventral prolegs translucent, in colour pale 

 grey ; the tuft-bearing tubercles are six in number on 

 each segment; the tufts on the second segment are com- 

 posed of single dark brown hairs, but the other tufts 

 are much denser, and formed of two sorts of hairs, the 

 more numerous being pale brown stiff hairs, with 

 sharp black points, and being sparsely barbed or 

 feathered ; the others, fewer in number, are taller, with 

 black stems, and densely feathered all round with soft, 

 pale brown plumage. 



The cocoon was of an oval form, about four lines in 

 length, formed of close-spun silk and attached to the 

 cover of the box in which the larva was confined ; the 

 hairs of the coat were all woven in, giving the cocoon 

 a brown colour and rough texture. 



The pupa skin, examined after the exit of the moth, 

 was about one quarter of an inch in length, highly 

 polished, of a rich deep brown colour, the segmental 

 divisions showing as pale reddish rings. (W. B. and

Plate XLIII, fig. 4. 



I am indebted to the unvarying kindness of Mr. W. 

 H. Harwood, of Colchester, for valuable information 

 concerning the habits of this pretty species, and for 

 opportunities of studying and describing its larva, 

 examples of which I received from him on June 15th, 

 1869, and on June 8th, 1871. 



These larvge fed on oak, principally on the under 

 cuticle of the leaves, and when full-fed, spun up in 

 small boat-shaped cocoons of silk, about five-sixteenths 

 of an inch in length, assimilating perfectly in colour 

 to the surrounding surface of the bark on which they
