 27. March 23, 1914. (Experimental cross breedings were made at Victoria, 

 Texas, between both sexes of the Arizona variety Anthonomus grandis thur- 

 beriae Pierce and the opposite sexes of the true Anthonomus grandis, bred 

 from cotton in Texas. Offspring were bred in each case, with very slight 

 differences in the length of the developmental period. There was a greater 

 variation in the rate of egg deposition per day. Typical thurberiae fed on 

 cotton squares oviposited only 0.2 eggs per day in May, but 4.5 eggs per day 

 in September; female thurberiae fertilized by male grandis laid 2.8 per day 

 in May, and 3.5 per day in September; female grandis fertilized by male 

 thurberiae laid 2.2 per day in May, and 1.9 per day in September. The off- 

 spring of the male grandis and female thurberiae rearings were interbred 

 and deposited 8.1 eggs per day; while the offspring of the male thurberiae 

 and male grandis rearings were interbred and deposited 3.5 eggs per day. —
