extremity as thick as the base, and greatly resemble 
those on some species of Caradrina. 
It isa very timid larva, contracting itself at the least 
alarm, and remaining a very long time afterwards 
without movement. Its usual. position in repose is 
a close coil, with its head twisted round on one side 
over the back of the tenth segment. (William Buckler, 
November 26th, 1870; H.M.M., June, 1871, VIII, 22.)

Plate CXVII, fig. 
Through the kindness of Messrs. Greening ca Bond, 
Mr. Buckler and myself have had the pleasure of 
rearing the larva of this species this season. 
The larva after hybernation, at the beginning of 
April, was about half an inch in length; and at that 
time, although rugose, and presenting a most decided 
‘wave’ -like appearance, was not at all so plainly marked 
as it afterwards became. ‘The ground colour was a 
warm ochreous-brown above, and a dark chocolate- 
brown beneath; and on the middle segments was a 
row of elongated diamond-shaped markings, shghtly

dots on each segment blackish ; along the spiracular 
region the dark and hght shades of brown met in a 
sort of zigzag line. - | 
About the 20th of April the larva moulted for the 
last time, and after that continued to feed for about 
four weeks. 
~ When full-fed it was about three-quarters.of an inch 
in length, belonging to the shorter and thicker type of 
Acidalia larve, rather flattened below, shghtly tapering 
from tail to head, rugose; the head small and bifid. 
The back of a buff-brown, brighter on the head and 
three following segments ; a dark subdorsal (but no 
dorsal) line on these same segments; at the fifth 
‘segment the subdorsal line ceases, and the dorsal row
