Going back to the long winged forms from the inbreeding of the 

 Fi generation short winged, their progeny which hatched in August 

 matured from December to February: 



Long Winged 20 : Short Winged 8 (i<i). 



These last short winged did not produce progeny until the following

Long Winged 336 : Short Winged 4 (F^).

This is nearly the same result as that obtained from the inbreeding 

 of the Fi generation short winged brothers and sisters. From the 

 inbreeding of the short winged of this last fraternity, progeny were
