CLEORA GLABRARIA. 
Plate CXI, fig. 2. 
For some acquaintance with this species in the larval 
state I have been indebted to Mr. Bernard Lockyer, 
who, on the 1st of June, 1875, kindly sent me a larva, 
and on the 10th six others ; and to these were added 
four more on the 22nd, from Mr. Tate, of Lyndhurst ; 
all of these having been found by him feeding on 
Usnea barbata growing on oaks in the New Forest. 
With the exception of the first individual, which 
died the morning after its arrival, these larve were 
very active, and fed well on the extreme points of the 
lichen, eating them down rapidly for about an eighth 
of an inch, and sometimes eating off the nodes, and 
more rarely the cuticle from the larger branches. I 
was attentive to keep their food changed, and to 
moisten it with water thrice a day, as [ soon found, if 
it became at all dry, they were unable to feed. 
One larva was contracting for its final change when 
it arrived, but had not strength to complete it ; on the 
16th of the month another had apparently ceased to 
feed, and would no longer remain on the lichen, but 
would mount to the gauze cover of its cage, persis- 
tently returning to it as often as removed. Various | 
substances and soils were supplied to induce it to spin 
up, but in vain; however, after the lapse of some days 
the mystery of its strange behaviour was cleared up 
by the appearance close by it of an ichneumon cocoon, 
or rather batch of four or five small cocoons spun on 
the gauze; another, later on, was victimised in pre- 
cisely the same manner, while three others proved 
healthy and vigorous, retiring when full-fed into the 
wet tree-moss kept beneath the lichens, where I ob- 
served they had each hollowed out a small cavity, 
which was kept in an oval shape by help of a few 
threads, rather far apart, spun across the opening ;
