Larva cylindrical, segmental incisions shallow ; thoracic legs well 
developed ; ventral prolegs on segments 3, 4, 5, these and ana] prolegs 
Alpha is a smaller seta than beta, and is situated above and in front 
of the latter in all segments excepting 9, where it is below ; on mesothorax 
The Cocoon. (Plate 68, figs. 1-3.) 
Two (occasionally three) leaves are cemented together with silk around 
their outer margins, two opposing leaves, one on either side of branchlet, 
being chosen ; their bases close to stems are first connected and gradually 
drawn together with silk, then the opposing margins. Should the leaves 
be more than usually difficult to draw together, the stem of one will be 
partly eut. In most cases leaves at ends of branchlets were chosen (see 
Plate 68, fig. 1). А fine thin. cylindrical cocoon is constructed, slung like a 
hammock across the interior between the leaves, usually in the direction 
of the long axis (Plate 68, fig. 3). The silk is exceedingly fine and strong ; 
is at first white but becomes later pale brown. Length, 6-7 mm. ; 
diameter, 1-5-2 mm. Anterior end attached to surface of one of the leaves 
near, but never at, the attached margin; here, just prior to pupating, 
larva prepares a small circular exit, the leaf being eaten away till only 
the thin transparent outer cuticle remains. Besides the cocoon the space 
between the leaves contains a variable amount of dry frass-granules, mostly 
collected to one side of cocoon and more or less adherent to it. Cast larval 
skin remains within cocoon. 
The Pupa. (Figs. 21, 22.) 
Cylindrical, extremities bluntly rounded ; abdomen slightly attenuated 
caudad from fifth segment ; free movement in male between 4—5, 5-6, 6- 
in female between 4—5, 5-6
