Relation of loss in body water to winter mortality of Mexican 
bean beetle.--R. L. Wallis, Estancia, New Mex., reports that in 
February 3 weighed samples, each consisting of 20. adults of 
Epilachna corrupta Muls.,were placed in a container with calcium 
chloride, to deterimine the relation between water loss from the 
body of the beetle and winter mortality. One. sample was removed 
every 48 hours and weivhea to susie the amount ef water loss. 
The results are similar to those obtained in comparable tests in 
s of water per sample averazved 6.045 gram for every

the weight of the sample had been lost in evaporation. There was an

W. A. Thomas, Chadbourn, N. 6., reports as follows: "Practically 
all adults and nympis of the common red spider (Tetranychus bimaculatus 
Harvey) on strewberries were killed the last two days in January, 
leaving an abundance of egrs apparently unharmed. These eggs hatched 
throughout Fepruary and some of the resulting nymphs were killed by 
intermittent luw temperatures. By the end of the month few eggs 
were present on the ‘hasite and some of the nymphs that escaped the 
cold had matured and had begun to lay egegs.

The Mezxicen mealybug on chrysanthemim.--H. H. Richardson, of 
the sreenhouse insects laboratory, Washinzton, D. G., reports aime 
the end uf the bluoming season (late fall end winter) many growers 
exchange their excess chrysanthemum stock plants of different vari-— 
etles in preparation for their next year's crop. If the flower crop 
has been infested, the stock »lants will vrebably also be infested. 
One instance of exchange of this kind has lately been observed and 
examination of the stock plants showed them to be infested with 
Phenacoceus possy yii T., & Ckli., thus indicating one probable manner 
of artificially dispersing this insect. During the winter many grow- 
ers kee» their stock plants in outside cold frames which are heated
