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.
