Tue Growru oF Insect Eoos.—Dr. J. A. Osborne, of Milford, 
Eng., has an interesting article (Hardwicke’s Science Gossip, Oct., 
1883, p. 225) on growth in the eggs of insects. He attributes it 
solely to moisture. The most remarkable instance we know of 
is that of the eggs of our katydids, especially of Phaneroptera 
curvicauda (see 6th Mo. Ent. Rep., p. 165). Here the egg re- 
mains so flat between the cuticles of the edge of a dried leaf that 
it produces no swelling ; yet before hatching it becomes cylindri- 
cal,even where the dry leaf is sheltered from dews and rains. 
Egg growth is usually great in proportion as the shell is delicate, 
and can generally be explained by endosmosis of moisture sur- 
rounding it; but here the shell is tough and can get no moisture 
beyond what is in the atmosphere, and there would seem to be an 
inherent swelling power consectaneous with embryological devel- 
opment.— C. V. R.
