REPORT UPON COTTON INSECTS. 



branches, though not on the very young leaves. Late in August, when the eggs for 

 the fifth brood were being laid, I found from one to nine eggs on some leaves, while 

 other leaves bore none ; and those which bore eggs were, as a rule, large leaves near 

 the middle of the plant. The average number on one of these leaves I judged to be 

 about four. To get more accurate results I examined, leaf by leaf, three plants, with 

 the results given below, and these partially confirm my previous observations. In 

 these tables the branches are counted from below upward, and the leaves, from the 

 base of a branch to its tip. Only unhatched eggs were counted, and such larvae as 

 were too small to have been born on a different leaf from that on which they were 

 found.

This was a spindling plant about four feet high. The leaves marked No. 1, on 

 branches 8, 9, 10, 11, 12, and 13, really belonged to the stem, the branches being in 

 their axils, and they were the largest leaves on the plant. The leaves marked as be- 

 longing to the stalk were situated above the highest branch. 



An examination of this table will show that the eggs were distributed according to 

 branches as follows :
