42 DEILEPHILA LIVORNICA. 



Deilephila LIVOENICA. 

 Plate XXV, fig. 1. 



On the 11th of July, 1870, a labourer brought me a 

 beautiful larva, which he had found in a mangold- 

 wurzel field near Exeter ; I offered it Galium saxatile, 

 vine leaves and Fuchsia, and it immediately attacked 

 the last with great avidity. 



My first impulse was to call it livornica, but the 

 description I consulted under that name did not suit ; 

 the points laid down in them as distinctive characters 

 I could not find,* hence I concluded that my prize 

 was galii, and under that name recorded its occurrence 

 in the ' Entomologist's Monthly Magazine,' VII, 61. 



The larva fortunately soon spun up, and resulted 

 in Deilephila livomica ? , which emerged on the 18th 

 of August. 



The following is a description of this larva made 

 with Mr. Buckler's good help ; to this I append some 

 notes communicated to me of other larvae found in 

 Devon and Cornwall. 



The length of the larva when stretched out is about 

 three inches and a half ; the head is the smallest seg- 

 ment, the body tapering towards it from the fifth seg- 

 ment; the anal prolegs broad and square, the horn 

 slightly curved, blunt at the tip, and rough ; the skin 

 rather shining, but on the hinder half of each segment 

 showing seven folds well defined at the sides, but not 

 so distinct on the back, where the skin seems tighter. 



The ground colour of the back and sides, as far as 

 the spiracles, is an intensely dark green ; the head 

 black, but with a streak across the mouth, as well as 

 the base of the papillae, lemon-yellow; the plate on 

 the second segment black ; an ochreous-yellow dorsal 

 stripe commences on the third segment and is con- 

 tinued to the horn, it is suffused with rose-pink, and 



* In saying this I was wrong ; the anal horn ought to have shown me 

 what the species was. — J. H., 24, 3, 86.
