This last genus may possibly not belong to the Satyridce ; the very

A LIFE HISTORY OF GRACILARIA SYBINGELLA. 
BY CHARLES HEALT. 
{Concluded from ipage 177.) 
The mode of procedure when the larva forms its cocoon on tbe 
surface of a leaf is this : it places itself at full length in a de- 
pression of the leaf, slightly raises the anterior segments, and moves 
its head from side to side, thus carrying a silken thread across, which it 
fastens to the leaf, till a sufficient number of these threads have been 
spun ; it then raises itself up till the centre of its body rests on the 
threads it has spun, its hinder segments stiU resting on the leaf below ; 
then, using its body as a measure, it stretches forth its anterior segments 
and begins the fabrication of one half of the outer covering of its 
cocoon ; this is done by carrying silken threads from side to side of the 
depression in the leaf, the larva gradually retreating backwards- 
"When the first half of the cocoon canopy is completed, the larva 
descends from its elevated position, turns round, and after inserting its 
hinder segments beneath the canopy just spun, it again raises its 
anterior segments and spins a few more silken threads, precisely as 
before, and, climbing on to them, it constructs the second half of the 
cocoon canopy like the first. 
"Whilst the larva is engaged in this occupation, as long as the 
observer keeps at a moderate distance, it continues its labours, but 
should he approach too near it ceases to work, and, after looking 
steadfastly at the intruder for a few seconds, retires under the partially 
formed canopy till the annoyance is discontinued, when it at once 
resumes its operations, and, if not interrupted, continues until it 
has entirely completed its task. The larva then crawls about on the
