68 DORSET LEPlDOrTERA IN 1892-3. 



not, however, believe that there is generally more than one hrood. 

 Tlie larva is not very active, though it can retreat quickly into its 

 tube when disturbed. It sometimes waves about the fore part of 

 its body, stretching it out to nearly double its ordinary length. 

 It is delicate and not easy to rear, so that I did not breed many 

 moths. 



Description of Larva. — The fuU-fod larva is about an inch in 

 length and tapers somewhat towards each end, especially the head, 

 which is less than half the width of the middle segments and 

 rather flattened ; the head and plates are a little more polished 

 than the body, which is dull. 



The ground colour varies a little in tint and may be described as 

 putty-coloured, witli a tinge of green, especially between the seg- 

 ments. The head and legs are pale brown, much mottled with 

 darker brown spots, the prothoracic and anal plates much like the 

 body, but a little more distinctly marked, the longitudinal lines 

 having a tendency to break up on them into darker spots, as on the 

 head, Tiiese lines, which are somewhat broader than in the young 

 larva, so that less ground colour is visible, are dark purplish brown, 

 and consist of a dorsal line (a trifle darker than the rest) and five 

 other slightly wavy lines on each side at equal distances from each 

 other, the fourth of which contains the spiracles, the fifth lying 

 along the ridge of the skinfold below. There is a medio-ventral 

 line, and the claspers and underside are more or less marked with 

 the same colour. The spiracles and warts are marked by very 

 dark brown rings and the bristles are pale brown. The booklets, 

 which are numerous, are dark brown. 



The larva changes its appearance very little during its life, with 

 the exception of the markings of the underside, which appear at a 

 very early period, I believe after the first change of skin. 



The pupa is about 5 lines long and very smooth and neat in ap- 

 pearance, the different parts fitting closely together. The antennae 

 and wing cases extend to the end of the 9th segment, leaving the 

 remaining four segments movable. The tail is rather blunt and 

 has about 6 small short hooked wire-like processes. The colour of
