SCALY WINGED COPEOGNATHA. 125 
confining a few of the insects in a glass jar together with broken 
tiles and pieces of cement, similar egg packets were deposited. In 
this case the covering material appeared to be cement dust worked 
up into a paste. Lach little nest contained about half a dozen eggs, 
packed side by side. The eggs are of a pale orange-yellow colour, 
irregularly oval, and measuring approximately 0°50 by 0°25 mm. 
I was unsuccessful in my attempts to hatch out these eggs. Some 
of them dried up without maturing and the remainder died and 
became mouldy. 
The nymphs may often be found in the company of the adult 
insects. They resemble wingless species of Psocus, and in some 
species are more or less clothed with scales—like the adults.
