noon, August 3rd, the resulting thirteen adults emerging from the 

 soil at 10 A. M., August 26th and 27th, and constituting the parents 

 of the third generation, which unfortunately was not carried through 

 to the adult stage, though larvae were obtained from the 96 eggs 

 deposited by them. The following schema and table represents 

 graphically these generations reared in confinement. Other 

 relative data are given in connection with a preceding table 

 (table II).

. It is interesting to note in connection with the third genera- 

 tion, that although in itself not reared to maturity on account of 

 the lack of opportunity, yet an almost parallel cycle was obtained 

 from a series of 13 larvae hatching at 8 a. m., August 30th, from 

 eggs deposited by Pair No. i, hibernated individuals or parents 

 of the first generation, and coming to maturity at 10 a. m., 

 September 25th; this generation of larvae was not more than four 

 or five days earlier than the third generation. There can be no 

 doubt that the parents of the third generation (or the adults of 

 the second generation) w^ere willing to reproduce to some extent
