Horticulture -- Oregon; Fruit-culture -- Oregon; Gardening -- Oregon. 376 REPORT OF STATE BOARD OF HORTICULTURE. eastern parasites are Aspldlotiphagus citrlnus Craw, recently reared from scales from W. E. Hudson, Orlando, Florida, and Ancqjhes gracilis How. which was reared orig-inally from specimens collected at Riverside, Mary- land, and later from affected twigs received from Charlottesville, Virginia. It is only fair to suggest that the latter species may not eventnally prove to be a parasite of the San .Jose scale, since overlooked specimens of the common oyster-shell bark louse may have been present on the same twigs. The type of this species was obtained in 1880 from Mytilasxiis pomorum. the common oyster-shell bark louse of the apple. Aphelinus fuscipennis is undoubtedly a very efficient aid in keeping the San Jose scale in check. Mr. Alexander Craw, in the report of the State Board of Horticulture of California for 1891, states that he found it doing such effective work in an orchard in the neighborhood of Los Angeles that complete extermination of the scale was confidently looked for. It was afterwards learned, however, that the orchard became reinfested and also that the partial extermination of the scale in this instance was in a measure seemingly due to a fungous —Aphcliaun Oiitspidis How. Islv. Koebele refers to the fact that in the case of infested trees on the island of Kauai the scales were neai^lj' all punctured by a minute para- site which he thought might be this species. PREDACEOUS INSECT ENEMIES. Of predaceous insects, perhaps the most interesting is the little coccinel- lid Pentilia misella, which in both the larval and beetle state was found by Mr. Schwarz in great numbers in Charlottesville feeding upon the scale, and which also occurs in other eastern localities. The present season we found its larvae on twigs from Chestertown, Maryland, collected late in November.
