This Spittle insect of the Pine was abundant on two trees on the campus of Blacksburg, Virginia, last summer, and an attempt was made to observe its oviposition and to work out its complete life-history.
Owing to lack to time this was not successful, but the following notes may be of some interest:
The Protective Secretion.—The material under which the nymphs live consists of a cler albuminous liquid, exuded by the insect, mixed intimately with bubbles of air introducted by the nymph after secretion; it is tasteless, or slightly salty.
