a month latev than usual, owing to the backwardness of the season. — Frederick 

 Bond; 24, Cavendish Road, October 19, 1860. 



Description of the Larva of Rumia cralcegata. — Bests in nearly a straight posture, 

 the head slightly bent downwards. Head small, slightly notched on the crown, 

 curiously impressed on the face, the impression being double — that is, a small trian- 

 gular depression within a larger and ragner one: a large erect nipple-shaped hump, 

 like a horn, on the back of the 7th segment ; two small distant warts on the back of the 

 8th, and two rather larger ones on the back of the 9th ; two abortive claspers beneath 

 the 8th segment, and two small but still useable claspers beneath the 9th ; a fringe of 

 fleshy tubercles on each side between the 10th and 13th segments ; these seem ap- 

 pressed to the twig when the larva is at rest. Colour very inconstant, varying from 

 green to brown, but generally opaque brown. .Feeds on Crataegus oxyacantha (white- 

 thorn). There appear to be two broods of this insect; I have had the larva full fed in 

 June, September and October. — Edward Newman. 



Description of the Larva of Eurymene dolohraria. — Head divided into two obvious 

 portions, indented on the crown, but not bifid : body with the 3rd segment evidently 

 ■incrassated or tumid j the 9th with a transverse dorsal swelling; there are no other 

 warts or excrescences either on the back or belly. Colour dark sombre brown, with 

 two distant white dots on the back of the 4th, 5th, 6th, 7th, 8th and 10th segments ; 

 ^piracies black, but the region around the spiracles rather paler, indistinctly mottled 

 with gray. Feeds on Betula alba (birch) ; full fed on the 2nd of October ; draws the 

 leaves of the food-plant together, and changes to a pupa in the interior; remains a 

 pupa all the winter. I am indebted to Mr. Thomas Huckett for this larva, as well as 

 for the three which follow. — Id. 



Description of the Larva of Selenia illunaria. — Head porrected, body when at rest 

 bent back at the 4th segment; the 3rd segment rather tumid at the sides; the 4th 

 rather tumid beneath, the 3rd pair of legs being seated in the swelling ; 8th and 9th 

 segments have each a pair of acute, approximate humps on the back. Body bright 

 rust-coloured, but neither uniform in tint as regards a number of individuals, nor of 

 uniform colour in the same individual, there being numerous shades and tints too 

 various and too inconstant to describe; on the back' of the 6th segment are two very 

 distinct yellow spots. Feeds on Betula alba (birch), and is double-brooded; the 

 second brood is full fed at the end of September ; it spins a slight cocoon among the 

 leaves, and remains in the pupa state all the winter. — Id. 



Description of the Larva of Selenia lunaria. — Rests in a curved posture and 

 oscillates the anterior part of the body when disturbed. Head not perceptibly notched ; 

 body singularly humped ; 3rd segment tumid, having on each side a large subdorsal 

 bump ; 4th segment rather tumid below, the legs on the swollen portion ; 6th segment 

 with a large transverse dorsal hump, and a smaller obtuse lateral hump on each side ; 

 7th segment with two dorsal warts and a large lateral hump on each side; 8th with 

 two dorsal warts; 9th with a large dorsal hump, having a double indentation on its 

 summit; 12th with two approximate small dorsal warts: colour green, gray or brown, 

 with scarcely any variety of shading. Feeds on Quercus Robur (oak) ; full fed in Sept. ; 

 spins a few leaves together, and remains in the pupa state throughout the winter. — Id. 



Description of the Larva of Selenia illustraria. — Head porrected ; body when at rest 

 bent back at the 4th segment, which is rather tumid beneath, the third pair of legs 

 being seated on the swelling; the back is bowed and the figure altogether very 

 singular; the 5th and 6th segments have each two small humps on the back; the 8th
