Description of the Larva of Nyssia hispidaria. — On the 

 1 9th of May last I received from Mr. J. P. Barrett, of 

 Peckham, a few larvae, which were then rather more than 

 half an inch in length, and were brown, with a double row 

 of orange-coloured spots down the centre of the back. They 

 grew very rapidly, being full fed on June 1st, when I took 

 the following description: — ^ Length about an inch and a 

 half, of tolerable thickness in proportion to the length. 

 Head narrower than the 2nd segment, retractile, flattened, 

 and notched on the crown. Body irregular, thick on the 

 anterior and posterior segments, thinner in the middle; seg- 

 mental divisions conspicuous, the anterior part of each being 

 narrower than the posterior ; along the spiracles on each 

 side, and on each segment, is a small pyramidal hump, those 

 on the 6th segment being larger than the others ; from each 

 of these humps springs a single short hair. The usual 

 tubercles distinct, black, those on the 12th segment almost 

 taking the character of humps, and lighter in colour than 

 the others ; a single short stiff hair also springs from each of 

 these. The skin has a wrinkled appearance. General colour 

 of an almost uniform dark brown ; head chocolate, variegated 

 with yellowish brown. Dorsal line rather darker than the 

 ground colour, and bordered on each side with a con- 

 spicuous interrupted line of rust-coloured marks ; between 

 the tubercles and spiracular humps are two faint rust- 

 coloured lines ; there is also a good deal of this rust-colour 

 along the spiracles, which are pinkish encircled with black. 

 A dull rust-coloured stripe (yellow on the 9th segment) 

 extends along the centre of the belly. Legs chocolate and 

 grayish white alternately. Feeds on oak, and turns to 

 a pupa beneath the surface of the ground. — Geo. T. Porritt ;

Description of the Larva of Tceniocampa leucograpJia. — 

 Rests in a nearly straight position on the leaves of Salix 

 viminalis (osier), on the leaves of which it feeds : it has a 

 limp and flaccid habit, and seems entirely without vigour. 

 The head is as wide as the second segment, and very 

 glabrous ; it emits from different parts of its surface sparsely 

 scattered hairs, all of which are directed forwards : the body 

 is of uniform size throughout, and has a slight lateral skin- 

 fold ; I fail to find the usual trapezoidal dots on the back ;
