PEMPELTA DAVISELLA. 281 



stripe, in bold relief to the foregoing as well as to 

 that which follows below, which is, in fact, a repetition 

 of the two pale, narrow, drab stripes, having a darker, 

 reddish-drab, ragged-edged, broader stripe between 

 them ; the belly is of a uniform, rather deeper reddish- 

 drab, slightly inclining to greyish ; the head has a pale 

 drab ground colour, but is so thickly marked with 

 blackish-brown spots and curved blotches as to 

 show but little, chiefly on the crown ; above the mouth 

 is a transverse whitish band, and the bases of the 

 papillse are also whitish ; on the second segment the 

 dorsal line is represented doubly, enclosing a fine 

 thread of pale drab; at the beginning of most of the 

 segments on each side of the back is a transverse row 

 of four or five small blackish-brown dots, seen only 

 while the larva is in motion, being hidden at other 

 times in the segmental folds ; on the side of the 

 third and twelfth segments, situated in the broad dark 

 stripe above mentioned, is a characteristic ocellated 

 spot, whitish-grey w T ith black centre, bearing a fine 

 pale hair, longer than that emitted by the ordinary 

 tubercular dots distributed along the sides and belly; 

 the spiracles are whitish-drab, ringed with blackish ; 

 the anterior legs are reddish-brown, the ventral legs 

 spotted and tipped with dark brown. 



In the two smaller examples, the broad blackish- 

 broWn stripe has a line of reddish-drab blotches 

 through the middle of its course, though but a faint 

 trace only remained of them in the largest example.

A description of the full-grown larva of Phycis 

 davisellus has been already published, but as its 

 earlier state has not been noticed, the following infor- 

 mation may be acceptable. 



The eggs of P. davisellus are laid in July and 

 August on young shoots of TJlex cawpestris, and as 

 soon as the larvas emerge they spin a thick network 

 of silk round the branch, and under this feed until
