No. 100. June 22, this green insect was talten.' After moulting the 

 same day the color was still entirely green; length, 15 mm. July 3, 

 moulted; color, legs green, dorsal thorax and abdomen greenish with 

 light brown patches; length, 19 mm. July 7, entire dorsal surface 

 light brown. July 12, entire insect straw-colored excepting all the legs 

 which were still greenish. July 13, moulted; entire body and forelegs 

 brownish; two pairs of hind legs still green; forelegs not as decided 

 brown as the body, but showed a transition stage between green and 

 brown; length, 22 mm. Aug. 8, moulted; all brown excepting hind 

 legs; length, 28 mm.; died. 



Thus we see that this insect showed the following rate 

 of development for the part of its lifetime under obser- 

 vation : 



June 22, 2nd moult^ 15 mm. 



July 3, 3rd moult 19 mm. 



July 13, 4th moult 22 mm. 



Aug. 8, 5th moult 28 mm. 



Whether a moult occurred before the length of 15 mm. 

 was attained on June 22, and whether any more would 

 have occurred after Aug. 8 and 28 mm., had the insect 

 lived, must be supplemented from notes on other indi- 

 viduals. 



No. 110. June 23, taken; color green; length, 14 mm. July 5, 

 moulted; green with brownish spots on the dorsal surface of first 

 three abdominal segments; length, 21 mm. July 14, moulted; straw- 

 color, with only four hind legs green; length, 25 mm.; died. 



So while only two moults could be observed in this 

 insect, they correspond rather nicely in dates and size 

 with those of No. 100. 



No. 111. June 23, taken; yellowish green; length, 16 mm. July 1, 

 moulted; yellowish green; length, 18 mm. July 3, no moult observed, 

 but length was 22 mm. July 10, moulted, entirely light brown except- 

 ing two pairs of hind legs and coxae of forelegs; length, 25 mm. 



No. 108. June 23, taken; entirely green; length, 16 mm. July 1, 

 moulted; all light brown excepting coxae of front legs and all of the 

 four hind legs, which were green; length, 18 mm. July 12, moulted; 

 entirely medium brown excepting legs as described before; length, 25 

 mm.; died. 



' The colors and changes will be again referred to later.
