PAMPHILA LINEA. 141 



which held the leaves together, and formed a lining to 

 the oblong puparium an inch and a quarter long, I 

 found the pupa itself to be of the length of 8-| lines 

 and very similar in form to that of its congener 

 Actceon, having the end of -the trunk lying free from 

 the abdomen, held in position, head upward, by an 

 oblique cincture behind the thorax, and the anal tip 

 secured by a fan-like spread of fine hooks at the ex- 

 tremity fixed in the silk lining, but the head had the 

 frontal tapering beak shorter and more bluntly pointed. 

 The colour then was the same light green as that of the 

 larva, of which the paler lines could still be faintly 

 traced. (W. B., 10, 3, 83 ; B.M.M. XIX, 244.) 



Pamphila sylvanus. 

 Plate XVII, fig. 4. 



I have reared this insect from a larva found feeding 

 on Luzula pilosa, nearly full grown, on May 1st, 1862. 

 It continued to feed for four or five days and then 

 spun a silken lining in a cylinder previously formed by 

 uniting the edges of a leaf of Luzula, in which it 

 changed to a pupa — the perfect insect appearing on 

 the 8th of June. 



The larva was very slow in progression ; cylindrical 

 above, flattish beneath ; the body pale bluish-green, 

 an indistinct dorsal line of darker green, and a paler 

 line above the feet, which are small. The head large 

 and singularly prominent — of a crimson-brown colour. 

 The thoracic segments taper towards the head, giving 

 it a strangulated appearance. (W. B., 9, 9, 62 ; ' Weekly 

 Entomologist ' I, 45.)
