(After Howard, TJ. S. dep't. agric. div, ent. Bui. 3, n. s. 1896j bugs introduced into California were colonized on trees infested with San Jose scale, and of these, three have since been discovered feeding on the pest. They are Ore us chalybeus, O. australasiae and Scymnus lophanthae. A fungus disease, Sphaerostilbe coccophila Tul., attacks this pest, and in some localities it has killed a considerable number of the scales. Prof. P. H. Rolfs credits this organism with practically exter- minating the pernicious scale in one Florida orchard and with reducing by considerable the numbers of the pest in others. It is undoubtedly a native of Florida, as it is very common onAspidiotus obscurus Comst. This fungus was cultivated, and new colonies of scales infested, but unfortunately, like other fungi it is very dependent on favorable.
