at Fort Sam Houston, found Captain Herms absent, but had a brief talk with Major — 
Kofoid who is very insistent upon the need of medicial entomologists in the sani a 
tary service of the great camps. He stopped at Dallas, Texas, to consult Mr, a

work in the fly-protection of packing-houses and elso interesting experimental — 
work against the heel-fly at one of the large dairy establishments. yee

culture of the National Museum, and Commissioner of the Department of Agriculture | . 
of Brazil, visited the Bureau of Entomology for two or three days during the month.

BROOD IX OF THE PERIODICAL CICADA IN 1918. 
The main location of this brood is the rather compact territory extending 
from the southern part of West Virginia, across Virginia into South Carolina, 
Widely separated swarms, of small import, have been reported from Ohio, A: num- 
ber of minor swarms occurred in northern West Virginia and one in northern Virg- | 
inia. Any Bureau men within this region and others are requested to 
report recurrence of these swarms this year. Next year, 1919, Brood 
Kk, the largest of the seventeen-year broods, is due, which will be therefore the 
great Cicada year of the current seventeen-year period. Brood X occupies the Ohio 
Valley and the Alleghany mountain region from Alabama and Georgia northward through 
Pennsylvania to scattered colonies in New York and some of the New England States. —

A PRACTICAL DEMONSTRATION OF THE APPLICATION OF THE PHENOLOGICAL CHART | 
TO WHEAT SOWING, 
, 
Dr. Hopkins has returned from a trip to West Virginia and reports that whea + 
sown on the date recommended in the wheat seeding map calendar for West Virginia, 
issued by the Department last fall, looks 50 per cent better than that sown 10 to 
1 days later. This indicates that if ell wheat had been sown on or near the dates 
given for the several States for which map calendars were issued, it would have r 
sulted in a greatly increased production this year. 
WINTER KILLING OF INSECTS, 
Extract from letter from Mr. Champlain, of February 18, 1918. 
"I find considerable evidence of winter killed woodboring larvae at this time 
In some of my Magdalis trees I find many dead larvae although it is not too soon 
get a percentage. As soon as we have a good thaw I expect to get some data on it. 
I find it so in standing infested trees and in some I felled and left lying on the 
ground. I do not notice much difference as yet but warm weather will show §t,. 08
