EXPERIMENTS IN THE BREEDING OF CERIONS.

The Loggerhead Key Colony K. 



In June 1915 we gathered 646 specimens of the first generation of 

 Florida-grown individuals at Colony E, of which 250 were photo- 

 graphed and measured and reported under that colony. The entire 

 lot was then planted in a httle meadow to the west of Colony E, which 

 is separated from Colony K by a fringe of bay cedars. They are in the 

 north end of this meadow, the ground being covered by a mixed 

 growth of Uniola paniculata and Sporoholus virginicus. The planting 

 is marked by a stake bearing a tag with the legend "Cerions, 1915, K." 



Table No. 10. —Measurements of the second generation of Florida-grown Cerion viaregis 

 from Loggerhead Key Colony K. 



This colony was thriving in May 1916. 



In July 1917 we found 2 adults of the second generation as well as a 

 large number of young individuals. 



In January 1919 this colony was again examined and 100 adult 

 specimens of the second generation were secured, measurements of which 

 are given in table 10 and photographs of them on plates 28 and 29.
