of town. The flight originated on an old levee situated on the north 
side of a big bend in the Mississippi River with the beetles flying 
southward and directly across the river. During the flight the pre— 
vailing weather conditions were: Clear, temperature slightly above 60° 
F., and a rather stiff breeze from the north. On December 6 *) = aaa 
beetle population (in a chrysanthemum field at Arlington Farm, Va.) 
was (found by Norman Allen to be) greatly reduced, compared with that 
which prevailed on November 25." 
The study by Dayton Stoner of the relation of the part that birds 
play in the control of the celery leaf-tier (Phlyctaenia rubigalis 
Guen. at Sanford, Fla., was mentioned in the November Monthly Letter. 
Mr. Stoner, reporting on the English sparrow, says: "The analyses Of the 
stcmachs of 61 adult birds collected in the Sanford celery district 
between November 29 and April 26 in the seasons of 1928 to 1930" show 
that 2.03 per cent of the food consisted of Lepidoptera (including 
0.34 per cent celery leaf-tier); 1.05 per cent Orthoptera; 0.69 per cent 
miscellaneous insects (Coleoptera, 0.56 per cent; Diptera, 0.14 per cen 
Hymenoptera, 0.03 per cent; others, 0.16 per cent); Araneina and other 
invertebrates, 0.86 per cent; vegetable material, 95.37 per cent. However, 
an analysis of the stomach contents of 22 nestling English sparrows shows 
that 49.05 per cent of the fcod of the young was of animal origin, in- 
sects alone comprising 48.5 per cent, and Lepidoptera alone making up 
33.82 per cent. 
W. A. Thomas, Chadbourn, N. C., reporting on the toxicity 73 
mole crickets of lead-arsenate-—treated soil, says: "In these experi-— 
ments it was observed that cannibalistic tendencies develop after a 
pericd of approximately three weeks, where the insects are kept in 
soil treated with lead arsenate without the addition of food other than 
that normally found in sand. This tendency becomes so pronounced that 
in most cases it is impossible to continue the experiment until the 
insects have all died of poisoning." The mole crickets dead at the 
end of 25 days ranged from none to 90 per cent. He continues: "Under 
field conditions they may easily escape the treated soil by burrowing ata 
lower level. It has also been observed in these experiments that where 
the soil is allowed to dry until the capillary moisture is exhausted, 
the mole crickets die very quickly, seldcm living under such conditions 
for as long as 24 hcurs." 
From Rodney Cecil, Ventura, Calif., we have the following note 
on the seriousness of pod-—borer injury: "A rancher in the vicinity of 
Ventura came to the laboratory recently for advice on control of the 
lima bean ped borer (Etiella zinckenella Treit.). His statement in 
regard to the injury from the ped borer agrees with our field obser-— 
vations. This rancher planted 200 acres of lima beans last spring: 
His costs records (not including rent of the land, labor, charges for 
plowing, planting, cultivating, or harvesting) were: For seed $300, 
threshing $370, and hand picking $221, or a total of $891. For this 
outlay he received $585 for 130 sacks of clean beans-——a loss of $306.* * *
