spicuous in the foliage to the naked eye. The caterpillar.s may be 

 beaten from the foliage in September and October. 



The eggs are deposited on the needles of the Scots pine. 



The caterpillars are lightish-green in colour. Jn the early stages 

 they may be compared to thread-like worms, beautifully harmonising in 

 colour with the foliage. When full-grown they change in colour, but 

 still harmonise with the foliage. The prevailing colour is sea-green, 

 with a whitish longitudinal line down the back, and a yellow line 

 along each side of the body, running parallel with the dorsal line. 

 The caterpillar (fig. 209) is from 1} to 1^ inch in length. 1'hey are

The pupa (fig. 210) is light-brown in colour. It may be noted

that in this insect ilie pupiil piirioil is of comparatively long duration, 

 and Altum points out ' that full-fed caterpillars and pupa are subject 

 to being attacked by several natural enemies, both fungi and insects. 



The male moth (fig. 211) has very strongly pectinated antennae, 

 whilst those of the female are quite simple. The body is slender, 

 whitish-grey, and approaching to yellow at the extremity. The pre- 

 vailing colour of the wings is a mixture of dark-brown and white. 

 The apical portion of the fore wing — a space about equal to one-half 

 of the wing — is a l>rown-ljlack colour, and the remainder of the wing 

 is practically white, with brown streaks. The under wings are of a 

 similar colour, but the white portion is more mixed with the brown 

 colour, and sometimes roughly divided into white and brown spaces.
