_Types_: Catalogue No. 20348, U. S. National Museum, the females on tags, a fore wing and an antennae on a slide. The abdomen is subpetiolate; it was distinctly, quadrately petiolate in a male specimen of _cleonymus depressus_ in the U. S. National Museum. _Entedon occidentalis_ Girault Several specimens, Claremont, California (C. F. Baker). _Isosoma grande_ Riley One winged female, mountains near Claremont, California (C. F. Baker). _Metapleura spectabilis_ Westwood One female, Claremont, California (C. F. Baker). The Rose Flea-Beetle (_Haltica probata_ Fall) G. F. MOZNETTE, ASSISTANT ENTOMOLOGIST, OREGON AGRICULTURAL COLLEGE, CORVALLIS, OREGON INTRODUCTION From a careful perusal of the literature it is apparent that scarcely anything but the original description of _Haltica probata_ Fall appears in print. As this species has at various times been reported on several of our cultivated plants, and as there is some possibility of its becoming destructive to our cultivated roses, observations have been made from time to time and this paper brings together, so far as possible, the recorded facts concerning the species. HISTORY AND DISTRIBUTION OF THE SPECIES The species was first described by Dr. H. C. Fall in 1910.[A] Mr. Arthur Gibson[B] mentions it as attacking leaves of strawberry plants at Nelson, British Columbia. The species is referred to as _Haltica evicta_ Lec., but after a comparison with specimens in the writer's collection and later in Dr. Fall's collection at Pasadena, California, I am led to believe that the species reported by Mr. Gibson as _evicta_ is not _evicta_ but _probata_. It has been reported from Spokane, Washington, on strawberries, and at various times has been reported feeding on cultivated crops in Oregon. The species is distributed along the Pacific Coast from British Columbia to California. It has been reported from Nelson in British Columbia; Everett and Spokane in Washington; from Corvallis, Pamelia Lake, Mary's Peak, the Three Sisters, and Josephine County in Oregon; and from Santa Rosa, Belmont, Siskiyou, and Trinity Counties in California.
