Head broadly cream-white between antennae, elsewhere more or less 

 brownish. Antennae white. Palpi whitish, long, slender, third joint almost as 

 long as second but with its base hidden by the prominent terminal scales of 

 the second; outer end of second and entire length of third with a brownish 

 gray stripe outside. The palpi are much like those of sulphurcodactylus. Legs 

 ochreous whitish, first two pairs suffused with gray-brown on one side. Spurs 

 moderate. Thorax and abdomen pale yellowish, the latter with two subdorsal 

 pure white stripes, visible only in clean specimens, and a slender brown dorsal 

 stripe. 



Primaries whitish to creamy or yellowish on inner margin, blending into 

 a deeper dull yellowish suffused with a light gray-brown shade in the costal 

 region ; immaculate. Fringes concolorous. Secondaries and fringes gray brown, 

 usually contrastingly dark but occasionally rather light in color. Expanse, 23-35 

 mm., usually not less than 27 mm. 



Distribution: Type locality Gallinas Canyon. N. M. Ariz, and 

 N. M. north into Utah and S. Cal., June to Sept. 



The general appearance of the primaries of screnits is usually 

 brownish ochreous, more whitish toward inner margin, but fresh speci- 

 mens in our series show that the basic ground color is clear yellow, 

 though of a duller shade than that found in sulphureodactylus. The 

 white stripes of the abdomen are visible only in specimens which are 

 free from grease. We have but one specimen which expands as little 

 as 23 mm., but have no doubt of its identity. Our identification of the 

 species is based on Mr. Meyrick's comparison with his type. 

 The life history is unknown.
