August 27. The young lingered two days on the empty egg-shells, 

 then began to feed. August 30 one died, apparently having fallen 

 to the bottom of the jar and being unable to recover its position after 

 landing on its back. August 31 all had their first moult and were 

 much increased in size. They were far more lively and congregated 

 on a green seed-pod which they seemed to prefer to the young 

 shoots and tender leaves. The second moult occurred September 

 6, ten survivors staying by their seed-pod in a lusty and lively con- 

 dition. September 11 the third moult occurred. After just emerging 

 from the exuvia the body was light and pale, the thorax, legs and 

 antennae were very light cream color, but in twenty minutes the 

 antennae and legs had become entirely black, while the abdomen was 

 greenish with red and yellow markings. The eyes were dark red. 

 The fourth moult occurred September 18 and the first imago appeared 

 September 27. All but one had emerged by September 29, the last 

 delayed until October i. The period from egg to imago therefore 

 covered 37 to 42 days.

August 7 I took a pregnant female of this bug. It had lost one 

 hind leg and the last joint of the left antenna so that this organ was 

 rendered useless. Its joints were motionless, each slightly bent 

 away and the whole carried at an awkward angle from the head. 

 The other antenna was in constant motion. Next day 27 eggs were 

 deposited on the jar. Their color was light yellow green with 

 bronzy metallic reflections and with many short black hairs. On the 

 top a row of longer white hairs, curved outward, were set around in 

 a perfect circle. This looked like a spherical cover to the egg, which 

 resembled under the lens some tinsel Christmas-tree ornament. 

 August 9 a mass of 9 and another of 16 eggs were laid. The first 

 batch of young, which hatched August 13, was very light salmon 

 yellow just after emerging. Other batches comprising 27 and 22 eggs 

 were laid. The next day the first born left their shells to hunt for 

 food. The mother had a habit of playing her good antenna over 

 and upon the youngsters, which showed no alarm. On the twenty- 

 first the mother died, presumably of old age, having bequeathed to 

 posterity 8 egg masses of 168 eggs in all. The smallest batch was 

 9 and the largest 27. The smallest batch and one of 16 were laid the 

 same day and perhaps ought to be regarded as a single mass, making;
