some egg-scars on the branch and I thought that she had been 

 ovipositing. The pair remained quietly in this position until 

 1.51, when the female began to drill a hole with her oviposi- 

 tor. Two minutes later the male trilled. At 1.57 the male 

 trilled again, dropped his tegmina, moved over in front of the 

 female and raised the tegmina again. The female paid no at- 

 tention to him, however, but removed her ovipositor, cleaned 

 it somewhat with her mouth, then moved down and began to 

 cover the egg. This she did by biting off some of the bark 

 in the immediate vicinity of the outer end of the egg, mixing 

 saliva with this, apparently, and pasting the mixture over the 

 egg-scar. While she was thus engaged, the male kept mov- 

 ing about, trilling occasionally, and finally went to the top of 

 the branch upon which they had been resting. At 2.17 the 

 female began eating a peach leaf at a point where it was 

 partly bad. Previous to this she had been moving about the 

 cage considerably and once got into position to receive an- 

 other sperm sac from the male. For some reason, however, 

 she did not secure one and she immediately left him. At 

 2.19 the male again approached the female, trilling, but she 

 moved away from him. They soon assumed positions on 

 separate leaves where they rested for some time. At 2.34 

 the male again sought the female and, trilling, backed up 

 to her with tegmina raised; she, however, paid no attention 

 to him. At 2.42 the male again backed up to the female and 

 she assumed the old position upon his back, but would make 

 no effort to secure from him another sperm sac, although it 

 was evident that he made an attempt to give her one. 

 Whether or not she received one from him soon thereafter I 

 cannot say, as my observations on this pair ceased for a 

 period about that time. At 4.05, however, she was seen to be 

 working away again at the thoracic depression and she had 

 another sac attached near the base of her ovipositor. 



I am under the impression that this was the third sac for 

 the day, in fact I feel quite positive that it could not have 

 been otherwise, but possibly it was the fourth. 



She continued to work away at the depression more or less
