ARGENTINE ANT ( Iridomyrmex humilis Mayr) 
Harold Ryan (June 29). In May we had a considerable number of 
inquiries from property owners in regard to winged ants fhat came 
to their notice. In practically all cases the winged male 
Argentine ant was submitted for identification. No female migra- 
tory forms of this ant were turned in, 
N, L. Douglass (July 18): In the localities where infestations 
of the Argentine ant occur the results of the control campaigns 
are pleasing in most cases. It is hoped that the only infestation 
in Granada County is practically exterminated. Very good results 
have been obtained in both the infestations in Yalobusha County, 
The only infestation in Carroll County looks as though at the 
present time eradication will be possible within 'the near future. 
Of the three infestations in Montgomery Co., no Argentine ants have 
been found thus far this spring at Duck Hill, Miss., and very few 
at Kilmichael, and while complete eradication at Winona is not in 
sight yet, a number of the blocks have been cleaned up this year, 
CONFUSED FLOUR BEETLE ( Tribolium confusum J.Duv.)

alive with larvae and beetles of this species developing in the 
heavy accumulation of hay dust during the last week in June,
