234 ENTOMOLOGICAL SOCIETY NOTES ON NORTH AMERICAN PART I. By E. A. SCHWARZ. [The'following series of descriptions was included in a Synop sis of the North American Psyllidae prepared by myself, at the request of the late Dr. C. V. Riley, in the years 1886 and 1887, but which has never been published. With the accumulation of material collected of late years in various parts of the United States and now preserved in the collections of the U. S. Depart ment of Agriculture and the U. S. National Museum, the Synop sis has become greatly antiquated, but it is my intention to revise and publish certain portions thereof, as well as to rescue from oblivion some fine drawings made for the Synopsis by the late Dr. Geo. Marx. This is done by the kind permission of Dr. L. 0. Howard, Chief of the Bureau of Entomology, U". S. Depart ment of Agriculture.] 1. NORTH AMERICAN SPECIES OF THE GENUS EUPHYLLURA FCERSTER. This genus belongs to the subfamily Aphalarinae Fr. Loew. and is very readily recognizable. The head has, in front of the anterior ocellus, two transverse lobes which are as wide as the vertex, contiguous throughout and, at their anterior edge, either conjointly truncate or slightly rounded separately. They are either connate with the vertex or more or less indistinctly sepa rated therefrom. The anterior ocellus appears, therefore, to be remote from the anterior margin of the head, and is visible only from above. The anterior wings are of rhomboidal form, /'. <?., suddenly widening at base, thence nearly parallel, apex not regularly rounded ; tip of wing, therefore, close to the anterior margin. Genital plate of male without lateral appendages. This genus contains a few European species ; in North Amer ica it seems to be confined to the Pacific slope. Our species may be distinguished as follows : TABLE OF SPECIES. Vertex flat; frontal lobes almost connate with vertex; wings entirely coriaceous; radius and 3d and 4th furcals straight or nearly so; 2d marginal cell triangular. Wings entirely brownish red, or with obsolete whitish spots, or with transverse white fascia; veins and sculpture of wings distinct, arctostaphyli, n. sp.
