COSSUS LIGNIPERDA. 137 



but no further, those on the first segment between 

 the wings are small, and the second row on the seventh 

 is very small, then come two segments each with a 

 single row of larger teeth, and the tail ends in a rough 

 escutcheon bilobed in the middle, and with a few 

 blunt points; no points on the belly, but cicatrices 

 in the places of the larval prolegs ; the skin somewhat 

 glossy, rich red-brown, paler at the segmental folds.

Cerura bicuspis.

I have no more to add to Mr. Buckler's notes beyond 

 the fact that alder is also the food of this species ; in 

 1886 I beat a half-grown larva from alder, September 

 9th. (J. H., 9, 12, 86.) 



Cerura furcula. 



Plate XXXII, fig. 2. 



Mr. Buckler figured this larva in 1860, October 

 26th, from sallow, also the piece of willow-bark show- 

 ing the cocoon; in 1867, August 23rd, from osier, and 

 October 3rd and 4th, from sallow, these last being 

 larvae taken at Rannoch ; he bred the moths May 17th 

 to 19fch, 1868. In 1865 I had pupae given to me, and 

 bred the moths June 1st to 8th. In 1886 I received 

 larvae from Mr. G. T. Porritt, July 9th ; these were quite 

 small, and the journey in the hot weather seemed to 

 have injured them, for they died very soon ; August 

 19th, I had larvae from Mr. W. H. Harwood, which 

 began to spin on the 21st. September 2nd, Mr. W. 

 H. B. Fletcher sent me several larvae varying in length 

 from 12 mm. to nearly 30 mm. ; and on September 

 6th I had from Mr. G. T. Porritt some larvae on the 

 point of spinning ; I fed them all on osier and narrow-
