made. The plant was kept trimmed and in a healthy and vigor¬ 
ous condition. The female lived as an adult from July 18 to Sep- 
- tember 8—a period of fifty-two days—while the death of the male 
did not occur until October 5, or seventy-nine davs after the last 
molt. 
No. 2 was prepared like No. 1 and at the same time. The in¬ 
serts remained in good condition throughout the entire period of 
the experiment. The total number of eggs deposited by the female 
was two hundred and thirty-three, or four less than the total from 
No. 1. The egg-laying period was the same in both cases. One 
hundred and fifty-one were taken from behind the leaf sheaths 
near the base of the plant, usually in clusters, and seventy-three 
were collected from the earth, this being thirty-nine less than 
were taken from similar situations in No. 1. The conditions of 
both cages were as nearly alike as they could be made, with the 
exception of the number of males in each, there being one in No. 1 
and two in No. 2. The eggs from the earth were found scattered 
more oi less about the cage at depths rangingfrom one eighth to 
•three fourths of an inch. They were most abundant near the base 
of the plant, on the roots. Eight young bugs were removed; two 
August 12, three August 21, and three September 9. The cage 
was examined August 12, 16, 21, 25, September 1 and 9, and Oc¬ 
tober 7. On the final examination, October 7, one bug in the sec¬ 
ond molt w r as removed from the plant. The grass was kept in 
good growing condition. The female lived fifty-three days, count¬ 
ing from the time of maturity, or from July 18 to September 9. 
One male lived until October 3—seventy-seven days—and the other 
until October 7, or eighty-one days after maturity. 
No. 3 contained a single female and three males. This experi¬ 
ment came to an untimely end August 21, when all the insects 
escaped through an opening at the bottom of the cage caused by 
the settling of the earth in the flower pot. Fifty-two eggs were 
removed August 13, twenty-four from the plant and twenty-eight 
fiom the earth. Twelve eggs and two young bugs were removed 
August 16, and twenty-five eggs and four young were taken out 
August 21. This cage was kept in good condition and examined 
several times afterwards. One young bug was removed September 
1, making a total of ninety-six eggs deposited by the female up 
to the time of escape. The number of eggs removed from Nos. 
1, 2, and 6 to August 21 is as follows: No. 1, 107; No. 2, 
129; No. 6, 69. 
No. 4, like No. 3, contained one female and three males. A 
careful watch was kept of this experiment, but none of the eggs 
were removed^ One male died July 20. The first eggs were ob¬ 
served July 25, and the first young August 15. The insects were 
seen pairing each day the observations were made. Fresh food 
was supplied from time to time as the bugs increased in number 
and matured. One hundred and thirty-four insects, including all 
stages of development, were removed October 3. The parent fe¬ 
male died September 7, having lived fifty-one days after casting
