The eggs of the sugar-cane froghopper appear to be usually laid in the dampest situation available, regardless of its nature; four females placed in a cage containing damp clay and slightly damp cane trash laid all but six of their eggs in the clay. Eggs laid in earth hatched in 20 days, the moisture content of the soil at the time of hatching being 21-78 per cent.; eggs removed from earth and placed in damp blotting paper were only ready to hatch after 42 days.
