ASSEMBLING. 355 



Experiment No. 28. 



July 26. At 8.50 A.M., one male moth, with three legs 

 removed, was placed on the experimental bench three feet 

 from four unfertilized females. At 9 A.M., he flew to the 

 partially drawn curtain and remained there until 10.45, when 

 he flew down from the window and mated with a female. 

 At 11 A.M. his antennae were cut off, but this did not pro- 

 duce any appreciable effect. They remained together until 

 11.30. After leaving the female, he remained inactive dur- 

 ing the rest of the day. 



Experiment No. 29. 



July 26. At 8.50 A.M., a male moth, with its wings 

 removed, was placed on the experimental bench at a distance 

 of three feet from four unfertilized females. At 10.20 A.M., 

 he approached rapidly within two inches of the females, but 

 eventually crawled away to a distance of three feet from 

 them. At 1.40 P.M., he was placed near a female on the 

 bench, but after a few minutes went away from her. At 

 2.05, he was placed within one foot of a female, and after 

 crawling slowly toward her, mated with her. 



Experiment No. 30. 



July 26. At 8.50 A.M., a male moth with both antennae 

 removed was placed three feet from four unfertilized females. 

 At 9, he had crawled a distance of one foot toward the 

 females. He remained quiet until 11 A.M., when he was 

 placed close to a female moth. He, however, paid no atten- 

 tion to her, and, up to 5 P.M., made no attempt to mate. 



^Experiment No. 31. 



July 26. At9.28A.M., the antennae of a small male were 

 coated with shellac and he was placed on the experimental 

 bench, at a distance of two feet from a number of females. 

 At 11.30, he had made no effort to mate with any of them. 

 He was then placed on a box containing a large number 

 of unfertilized females, but showed no animation. Other 

 males, with their antennae not coated, were continually hov-
