Mayer^ has given us good evidence that the sense of 

 smell, rather than sight, plays a large part in mating. 

 Our experiments upon the removal of the antennae quite 

 substantiate his work, for in every case where both 

 antennae of the male were removed, mating did not occur. 

 The condition was the same where only one was removed, 

 but the removal of one-half of each antenna seems to 

 offer no hindrance to mating, nor does the absence of both 

 antennae of the female.
