Life-history: A female of the grey form deposited a batch of 

 8 eggs, Dec. 28, 1905. They were inserted in soil, in a cylindrical 

 mass about 12 mm. long by 4 mm. in diameter, held together by 

 a yellowish brown, dried frothy material. The eggs are 4 mm. 

 long by 1 mm. thick, cylindrical with- rounded ends, finely reti- 

 culated, and of a dull testaceous color. One female under ob- 

 servation deposited four clusters of 27, 28, 36 and 38 eggs respec- 

 tively. Of the first lot of these, the first egg to hatch was Feb. 

 13th; four more hatched Feb. 15th, giving 47-49 da3'-s for the 

 egg-stage. Three of these were reared to maturity. Observa- 

 tions were interrupted so that the time of all the molts was not 

 observed, but their number was determined by the counting of 

 exuviae in the breeding jar: five times for the males and six times 

 for a female. The period between molts has been observed to 

 range from 10 to 20 days. 



The freshly-hatched nymphs were 5 mm. ; green, dotted and 

 marked with white ; anterior and intermediate legs grey-spotted. 

 (In subsequent lots of 37 and 14 freshly-hatched nymphs, all were 

 of this same coloration). The first molt occurred after 17 days, 

 and then the nymphs were green, the anterior and intermediate 

 legs green like the posterior ones. They remained green thruout 

 their subsequent stages. Two matured to green males, May 24 

 and May 25 respectively; and one matured to a green female, 

 June 6. This gives about 100 days for the nymphal period of 

 the male, and about 112 days for the female. This may be longer 

 than it would have been in a state of nature; as the conditions 

 of the breeding jar may not have been at all times the most fav- 

 orable for growth and development. The egg-stage plus the 

 nymphal stage gives about five months from egg to maturity.
