Chrysohothris azuren and Lepfurges querci, both wood-boring species, 

 were found in dead branches of Wislaria chinensis at Iowa on the 28th 

 May 1914. Adult males and females emerged between 29th May 

 and 10th June. The large numbers of L. querci indicated a high degree 

 of infestation.

While studying the effect of poisoned bait on grasshoppers in western 

 Kansas in 1913, large numbers of dead cottonwood borer beetles 

 {Plectodera scalator) were observed. Investigation showed that death 

 was not due to poisoning, but to the presence of a parasite, Sarcophaga 

 vericauda, a species which has hitherto only been reared from grass- 

 hoppers.

Like acid solutions of copper, ammoniacal ones have the property 

 of keeping part of the copper in solution and immediately active. 

 Such a fornmla is that of " eau celeste" (Audoynaud process), which 

 contains 1 lb. of copper sulphate, 0'120 pints of 22° ammonia and 10 

 gals, of water. Phenolphtaleine is usually employed for testing 

 neutral Bordeaux mixture. The paper is easily prepared by dissolving 

 1| grms. of phenolphtaleine in 50 grms. of 90° alcohol ; white blotting 

 paper or filter paper is dipped in this solution for a few minutes and 

 then dried in the sun. If protected from damp, this paper keeps for 

 several years in good condition.
