attributing this to previous annual campaigns against them. Incidentally 
another locust, Locusta migratoria L. , is reported to have assumed consider- 
able importance in the Sudan. (Reported December 25, 1933.) 
Cur main cane insects are the two Pseudococcu s — P. calceolariae Mask. 
and P. boninsis Kuw. In former years they have caused much damage, hut have 
"been hut little in evidence this past year, possibly owing to the record 
breaking heat last June, when the maximum in the shade in the Upper Egyptian 
cane fields was very frequently about 115 degrees and several times approached 
120, and also to the ravages of .coccinellids, which right now (Nov. 15, 1933) 
are very abundant. 
Incidentally a cane jtest, Aphis maidis Fitch has been destructive to 
latre maize this season (1933), in many cases the tassels having been so 
seriously damaged as to interfere with pollination. The attack was most 
notable during the last weeks in October and the first of this month, and 
one of our entomologists told me yesterday that he estimated a loss of around 
half a million bushels of corn in Egypt as a result of this insect's attack. 
Natural enemies appear to be particularly scarce this year, although 
coccinellids and syrphids are now (November 15, 1933) getting in some good 
work.
