Notwithstanding a set-back, due to the very unusual climatic conditions of the 

 winter of 1911-1912, the cotton boll weevil gained 7,300 square miles, the total 

 area infested being 278,800 square miles, as follows: 149,700 sq. miles in Texas, 

 (139,300 in 1911); 40,800 sq. miles in Louisiana (stationary); 2,100 sq. miles in 

 Oklahoma (6,300 sq. miles in 1911); 25,000 sq. miles in Arkansas (33,900 in 

 1911); 3,600 sq. miles in Florida (1,400 in 1911).

In February 1913, an insect resembling the cotton boll weevil was found 

 breeding in the bolls of a shrub known as Thurberia thespesoides in Ventura 

 Canyon, Arizona. A close examination of the material disclosed many minor 

 points of difference from the usual form of the cotton boll weevil. In addition to 

 these differences of structure, certain differences of habit were noted: It was 

 found, however, that A. grandis would feed upon Thurberia, while the Arizona 

 species would equally feed on cotton; and it was possible to obtain crosses of the 

 two forms. It was, therefore, decided to regard the two as being merely different 

 varieties of the same species. For the Arizona variety the name, A . grandis 

 thurberia , Var. N., was proposed. A systematic description and an account of the 

 life-history are given.

Referring to his article on the Peruvian square weevil in J. Econ. Ent. for 

 April 1911, the author believes that he has now collected sufficient palaentological 

 evidence for the deduction that "A. vestitus has probably attacked cotton in humid 

 northwestern South America for upwards of a million years, if not longer. It is, 

 therefore, extremely probable that this species is not confined to Peru and 

 Ecuador." One of the periodic separations between North and South America 

 explains the fact that A. vestitus does not occur in North America and that 

 A. grandis was not dispersed as far as South America. Both the weevils have 

 originally developed on cotton, having no other foodplant.
