I CYMAT0PFI0KA DUPLARIS. 



having the ocelli as a black spot on each side, and the 

 mouth blackish; the base of papillse yellowish; on the 

 second segment is a small black polished plate. The 

 skin of the rest of the body is very thin, but without 

 any gloss — indeed, remarkable for its opacity of surface, 

 the segmental folds showing yellowish. 



These larvas feed on birch, between united leaves.

On July 3rd, 1873, arrived some eggs of this species, 

 laid singly and in twos, on the edges mostly, of birch 

 leaves, from Mr. James Batty, of Sheffield. On the 7th, 

 when I first saw them, they were a pale whity-brown 

 or cream colour — turning during the night to a faint 

 grey tint, and on the afternoon of the 8th they began 

 to hatch.

The egg is oval and ribbed longitudinally and very 

 finely reticulated, and is gummed to the leaf length-

The newly hatched larva is large in front, tapering 

 behind, of a whitish colour, with a very pale whity- 

 brown head ; on the 10th the larvas had become very 

 pale green. (W. B., Note Book II, 21.) 



Cymatophora ocularis.

On the 28th of May, 1874, Mr. J. E. Fletcher, of 

 Worcester, very kindly sent me a dozen eggs of this 

 species which had been laid the 23rd and 26th of May ;
