XYLOPHASIA HEPATICA. 59 



plate is filled in with very dark blackish-brown, still 

 conspicuous as at first ; the ground colour is of a dark- 

 ish purple grey-brown, much and finely freckled with 

 darker; through this runs the paler ochreous-brown 

 dorsal line ; a faint subdorsal stripe of unfreckled 

 ground colour, edged with coarser freckles, can just be 

 discerned ; the tubercular spots blackish-brown ; above 

 each spiracle is a larger tubercular spot than any of 

 the others ; the spiracular region and belly reddish- 

 ochreous freckled, but paler than the back ; the spira- 

 cles of the same colour, finely outlined with blackish ; 

 the shining plate on the anal segment has paler dorsal 

 and subdorsal lines. 



At the beginning of November it moulted again, and 

 now the plate on the second segment was all black 

 alike, with the exception only of the pale lines ; the 

 larva now, in all its details, showed itself to be unmis- 

 takably X. hejpatica, though of a darker purplish-brown 

 and less grey than those full-fed examples of this 

 species which I have myself found in the spring. 



This larva continued to wake up and feed at inter- 

 vals up to the 1st of January, 1877, when I noticed 

 its length was somewhat less than before, though still 

 alive ; but on the 7th I found it dead. (W. B., Note 

 Book III, 154.) 



Xylophasia scolopacina. 



Plate LXIIT, fig. 4. 



I am indebted to Mr. Batty for two healthy larva3 of 

 this species. They feed on coarse grasses and a 

 species of wood-rush. Their bodies are uniformly 

 cylindrical and slender. The head and plate on the 

 second segment are of a translucent greenish tint, and 

 there is a black mark on each side of the mouth. 

 Ground colour of the body olive-green above ; on the 

 back a fine thread-like line of yellowish or pale grey- 

 ish, enclosed by two others of dark grey, which form
