In Table XII one of the most striking points is the rather uniformly 

 hiirli percentage of parasitism in each section found in dried hanging 

 bolls and squares. By far the highest percentage of parasitism is the 

 21.S per cent shown in dried squares in central Texas. Western 

 Texas leads in the percentage of parasitism in fallen squares, but when 

 the comparatively small number (287) of weevil stages found is con- 

 sid(>red, it would aj)pear that 8.5 per cent may l)e largely in e.xcess of 

 the percentage which would have ])een found in so extensive a stories 

 of observations as was made in central or southern Texas. A similar 

 exception siioiild be noted for the 100 ])er cent of mortality ffom ant 

 work in dried hanging bolls in western Texas where only a single 

 weevil stage was found. In ch-ied hanging s(juares the mortality 

 from heat, as a general j'ule, very nearly equal- that from ant attack, 

 while in other classes of forms ants destroyed many more stages of the 

 weevil than did heat and parasites together. 



In regard to anl work, it is evident that the high percentage shown 

 among fallen s(|uares in each of the six sections examined is \(>ry 

 imj)ortant. This is especially so because of the fact that these per- 

 centages apply to the largest series of examinations made, the mimber
