 ill. p)iceaella, sp. n., on Picea excelsa; and Rhopalosiphum tulipaeella, 

 sp. n., on cultivated tulips and violets.

 mission. — Jl. Econ. Entom., Concord, ix, no. 3, June 1916, 

 pp. 362-363. 



The theory that bees may be concerned in the transmission of fire- 

 blight [see this Review, Ser. A, iv, p. 187] is criticised on the ground that 

 it is not supported by experimental data. There is no proof that the 

 bacteria enter the hive, and the latter cannot therefore be regarded as a 

 centre of distribution. Further evidence is needed as to the relative 

 importance of flying insects and Aphids in spreading the disease. The 

 author suggests the desirability of attempting to isolate Bacillus 

 amylovorus from the mouth-parts of bees as they leave the hive.

 Concord, ix, no. 3, June 1916, pp. 364-366. 



The experiments described in this paper were undertaken in con- 

 sequence of the high mortality which has occurred during recent years 

 in apiaries in Massachusetts. The assumption that death was due to 

 arsenic poisoning was borne out to a considerable degree by chemical 

 examination. Traces of arsenic were found in 12 out of 23 samples 

 submitted and also in stored pollen. Further investigations are being 

 carried out to determine the amount of arsenic present in the samples.
