deposit light-green eggs. This is an individual characteristic, the 

 cause of which is unknown. The color of the eggs remains constant 

 in each successive laying by the same female. From two to three 

 days before hatching, both the yellow and green-colored eggs take on 

 a pinkish shade which increases in depth until the cap-end becomes 

 nearly red, just before hatching. The number of eggs laid by different 

 individuals varies; one insect may deposit three clusters of eggs. The 

 first laying is always the largest, usually consisting of between 40 and 

 50 eggs, although som.e individuals do not deposit nearly so many. 

 The second laying of eggs contains commonly about half the number 

 in the first, although this sometim.es varies. The third cluster, when 

 there is one, commonly contains from two to six eggs. They adhere 

 to each other by a cement-like secretion deposited by the parent and 

 are attached to the leaf by a similar substance. They are oval-shaped 

 and are large -t at the top, or cap-end. They measure about one- 

 sixteenth of an inch high, by one thirty-second of an inch across. 

 On looking closely, one will see a small circular cap, around which is a 

 single row of rather stubby, clubshaped, spine-like processes. The 

 eggs hatch in from seven to nine days. The period from the egg to 

 the adult varies. The shortest period from the tim.e of hatching of 

 the egg to the adult stage, recorded during this season's experim^ents, 

 was from July 23 to September 10, or a total of forty-nine days, the 

 cluster of eggs having been laid on July 14. The longest period, which, 

 by the way, was from this same egg cluster, was from Julj^ 23 to Octo- 

 ber 6, or a total of seventy-five days. The follo^\dng is a record of 

 the life history of the young bugs- hatched from the above egg-mass. 

 Eggs hatched July 23 during the forenoon, and the young nymphs 

 remained in a mass beside the egg shells from which they hatched, with- 

 out feeding, until 4.15 p. m., July 28, when they commenced molting. 

 After having molted, they separated and started feeding on the berries, 

 continuing to feed and resting at intervals until some time between 

 4.30 p. m., August 6, and 7.30 a. m., August 7, when most of them 

 molted. The final specimen did not, however, molt the second time 

 until August 8. August 13 two specimens m.olted the third time, 

 carrying them into the fourth instar. They continued molting at 

 intervals until sometime between 4.30 p. m., August 17, and 7.30 a. m., 

 August 18, when the last two molted the fourth time and from this 

 time on specimens molted at intervals until they had all molted the 

 fourth time on September 2. On September 10, two specimens molted 

 the fifth time, becoming adults, and the molting continued until the 

 last specimen transformed some time between 4.30 p. m., October 5, 

 and 7.30 a. m., October 6. This was, by the way, the latest record 

 which I have for the maturing of this species in captivity.
