Arphia arcta (Scudder). 



Jerome, Yavapai county, Arizona. June 26. 1902. (Oslar.) Two 

 males, two females. 



Albuquerque, Bernalillo county, New ^lexico. July 12, 1902. 

 (Oslar.) One female, 



I cannot agree with CaudelP in uniting A. teporaia with this species. 

 They appear to me quite distinct, and separable by the length of the 

 tegmina and wings in the female, and in the form of the vertex. In 

 this connection I have examined thirty-seven specimens of the two 

 species. 



Arphia canora n. sp. 



?1902. Arphia nietana Scudder and Cockerell, Proc. Davenport Acad. Sci., 

 IX, p. 28. (Not of Saussure.) 



Types: d^ and 9; Salt Lake City, Utah (c"). and Albuquerque, 

 Bernalillo county. New Mexico. (Oslar: July 15. 1902.) ( ? ) 



Allied to A. nietana Saussure, but differing in the slenderer form, the 

 narrower vertex, the more vertical face, the longer metazona and the 

 slenderer posterior femora. 



(^. — Size medium; form somewhat slender. Head with the occiput 

 bearing several longitudinal rug£e, the median one extending forward 

 to the tip of the scutellum of the vertex; scutellum p\Tiform, longer 

 than broad, very slightly excavated, margins moderately high, the 

 median carina broken centrally; lateral foveolae elongate, subtrigonal, 

 not strongly marked; frontal costa broad and subequal inferiorly, at 

 the ocellus expanded and slightly and shallowly excavated, above the 

 ocellus distinctly constricted, subequal, apex truncate, this portion 

 w^ith a distinct median carina; eye not prominent and about equal in 

 length to the infraocular portion of the genae; antenna a1)out equal 

 to the head and pronotum in length. Pronotum with the median 

 carina rather low, even, distinctly cut by the last sulcus; anterior 

 margin very obtuse-angulate ; posterior margin acute-angulate with 

 the angle rounded ; surface of the disk rugoso-granulate ; lateral lobes 

 of the pronotum subequal, deeper than wide. Interval between the 

 metasternal lobes slightly longer than broad. Tegmina moderately 

 long; apex obliquely truncate; greatest width about median. Wings 

 not elongate, two-thirds as wide as long. Posterior femora robust, 

 reaching to the apex of the abdomen, superior and inferior margins 

 equally arcuate. 



9. — Similar to the male with the following important exceptions: 

 Scutellum of the A-ertex broad, about as broad as long; frontal costa
