worthy of some attention. It is undoubtedly true that each of 
these floral regions is also a distinct subfaunal region. It may there- 
fore be expected that different weevils will exist in the different 
belts and different parasites operate upon these weevils. Some 
of these parasites may be able more readily than others to adopt 
the boll weevil as a host, or in certain regions there may be more 
species of parasites capable of doing this. In the discussion of the 
geographical distribution of the parasites more light will be thrown 
upon this question.

BOLL WEEVIL STATUS. 
That there should be some definite relation between the percent- 
age of infestation and the percentage of parasitism was expected, 
on the ground that a condition favorable to the weevil should be 
favorable to the parasites. It was, of course, conceded that climate 
would be another agency to figure in the question. The year’s 
work is deficient in that coordinate examinations of infestations and 
parasitism were not taken. In another year this will be necessary 
in order to show whether the parasites are reducing the infestation. 
At present no relation can be found between parasitism and infesta- 
tion or climatology. Beeville, Goliad, and Victoria have a mean
