arch. Its length is fiom 1 inch and 5 lines to 1 inch 

 and 9 lines. The head is flattened, somewhat spade- 

 shaped, as wide as the 2nd segment, and porrected in 

 crawling; the anlennal papillae conspicnous. The body is 

 elongate, stoutest behind, and uneven in form ; the 3rd 

 segment is dilated laterally ; the 6th has a conspicuous, 

 transverse, dorsal hump, and also a smaller one on each 

 side ; the 8th has a lateral projection, and both it and the 

 9th have two inconspicuous dorsal points; the 10th bears a 

 large, bifid, dorsal hump, and smaller lateral ones ; and the 

 12th has two small dorsal points; the 13th segment termi- 

 nates in two inconspicuous points directed backwards. The 

 skin is much wrinkled transversely, and there is a lateral 

 skinfold containing the very inconspicuous spiracles. The 

 colour of the head is dull blackish; of the body dull umber- 

 brown, mottled, and clouded with pale, dull olive-green. 

 There is a pale line on each side of the back of 5th segment, 

 and an indistinct, large, pale, somewhat oval mark on the 

 dorsal surface of each of the 6th to 10th segments. The 

 humps are very dark umber-brown; that on the 6th segment 

 having a short, pale greenish line down each side. The 

 ventral surface of the 12lh and 13th segments is entirely 

 bright olive-green ; that of the remaining segments is dull 

 olivaceous, with two longitudinal brown stripes, extending 

 from 5th to 11th segments. Ihe legs are umber-brown; the 

 claspers mottled and clouded like the body ; the spiracles 

 are ochreous, each in a delicate black ring. One of my 

 larvae had the ground colour a dull reddish brown. They fed 

 on oak and birch, preferring the latter; and when full fed 

 spun a slight cocoon between the leaves of their food-plant, 

 in which they turned to pupa, which were elongate, lively, 

 pointed at the anal extremity, and dull olivaceous in colour, 

 spotted, and streaked with darker. A variety of the pupa is 

 pale bluish green, without n)arkings. — Bernard Lockyer. 



Description of ilie Larva of Fidofiia aioniaria. — In Mr. 

 Newman's work on the 'British Moths,' there is a description 

 of this larva, translated from the French of M. Guenee; but 

 it is so meagre that I venture to place on record a few notes 

 on the species which 1 took a few years ago. In the spring 

 of 1870 I obtained a small batch of eggs from a female, 

 captured at Shirley. These were small oval, and of a bright
