tinuously a relatively thick ultimately opaque and white thread. 
As, too, the insects when in this larval state, though active, dc 
not move far from one another, these threads soon interlace, and 
thus the leaf appears to have white glistening objects scattered 
over its ^-een surface. The insects now soon insert their 
probosces uito the leaf-tissue, after which event they probably 
move but little. They now, too, elaborate from the milky plant- 
juice and excrete an extremely viscid and tenacious sub.stance 
which, however, does not adhere to their own bodies since these 
are covered by this time with a mealy secretion. This glutinous 
substance becomes blended with the foregoing threads and forms 
a compact low canopy beneath which the insects, arisincr from 
each groqp— or conjoined groups— of eggs feed. It, moreover, 
day-by-day, becomes more extensive, elevated, and darker. The 
insects after several ecdeses, or changes of the skin, eventually 
cease feeding and become active pupm. In this pupal condition 
they resemble the larvm but possess conspicuous wing-cases as 
an aditional feature. The pupm after a while erawfout from 
beneath their covering and may be found scattered all around it, 
usually viithin a distance of half-an-inch. And from them the 
perfect or vsnnged insects emerge through a longitudinal opening 
behind the head. It now resembles a miniature cicada airhas”
