Several new points connected with the life history of the insect are brought out. 
Among these is the spinning of a web by the first stage larva in many cases, under 
which it works while boring its way through the carpel of the boll. The statement 
is also made that the pink bollworm has been observed to injure the stem of cotton 
plants. At one of the experimental farms a number of plants had broken off about 
six inches above the ground. Examinations showed that at the break the stem had 
been completely girdled, and the culprit was found to be the pink bollworm. The feed¬ 
ing of the larva in the blooms, which has been referred to only casually by other writers, 
is dealt with fully. In many cases the larva works in the pollen where it spins a 
protecting membrane and pupates. This habit has recently been observed in Mexico, 
but the Mexican observations have not been published. Of equal interest are the exact 
data regarding the location of the eggs on the cotton plant. In an examination of 
twenty-five plants a total of fifty-nine eggs were found. Of these 62 per cent were 
on small leaves at growing points and about the squares, 12 per cent on large leaves, 
10 per cent on squares, 12 per cent on bolls and 3 per cent on the bracts of squares 
and bolls. 
The author found that moths would emerge after a resting larval stage of twenty 
months. Only 28 per cent of the larvae were killed by sixty-nine hours submergence 
in water. 
Control measures are treated exhaustively, but they are largely peculiar to Egyp¬ 
tian conditions and will not be dealt with here. 
The author has made one of the most important contributions to entomological 
science which has been presented for several years. He is to be congratulated on 
the work he has done, and it is to be hoped that the appearance of the remaining por¬ 
tion of the volume and of other possible volumes may not be long delayed.
