DEATH OF GUSTAF FALKENSTROM The late G. Falkenstrom of Stockholm, Swcden, specialisl on dytiscid and haliplid water beetles, published over thirty articles, several of which are of immediate interest to American stutlci~ts. The Collowing nole on his life iq taken from an obituary by Dr. N. Kemner, "Gustaf Falkenstrorn och hans sam- lingar, som nu donerats till Entomologiska Inst itutionen i Lund" (Gustsaf Falkenstrom and his collection, now donated to the Entomological Institution in Lund) , Opuscula Entornologica 7:108-1 11, with portrait. I am indebted to Per Brinck of Lund for a copy of the obituary and to Mr. F. Godber of Vernon, B. C., for a translation from the original Swedish. Gustaf Adolf P. Falkenstrijm was born on November 13, 1867, at Hjule- herg i Arsradr, S~veclen,and died in StacUohn on August 15, 1942.
