Abstract
In March of 1935 specimens of lace bugs (Leptopharsa Heveae Drake & Poor) on Hevea brasiliensis from Para, Brazil, were sent by Dr. C. H. T. Townsend through the Bureau of Entomology and Plant Quarantine to the Division of Mycology and Disease Survey, of the Bureau of Plant Industry, for the determination of a fungus thought to be parasitic on the insects. Observations made by Dr. Townsend indicated that the fungus had been fairly effective in controlling the lace bug which had been causing some concern as a rubber plant pest. He stated that a considerable percentage of the immature stages of the insect had been attacked and killed. Later, Dr. J. R. Weir sent additional specimens of the same insects attacked by this fungus, with the information that the fungus had practically destroyed the bugs over wide areas in certain of the localities where rubber plantings had been made. Additional specimens have been received from time to time from Dr. Weir who has made extensive field observations.
