Thomas' name has priority as it was published in June. I have pre- 

 ferred Scudder's name, however, because it was the type of the genus.

Hab. Texas (Scudder) ; San Joaquin Valley, California (Coquil-

The United States National Museum contains several specimens 

 from San Antonio, Texas, which I have referred to this species.

Hab. Garden of the Gods, Colorado (Scudder) ; Southern Cali- 

 fornia (Riley).

5. Stirapleura euroti^e, Bruner. 



Psolocssa Q) euroticB, Bruner, 1889. Proc. U. S. Nat. Mus., XII, 62. 

 Hab. Laramie River (Bruner). 



This species is said by Bruner to feed solely upon Eurotia lanata or 

 sweet sage or winter-fat as it is variously known. 



XXXI. PSOLOESSA, Scud. Figs. 31a, 31b. 



Vertex very slightly declivent, narrow, being less than half the short 

 diameter of the eye and scarcely equal to the width of the frontal 

 costa at the clypeus. It is deeply sulcate with high carinte which are 

 parallel throughout the greater part of their extent and which meet in 

 front at an acute angle and are somewhat incurved posteriorly where 

 they continue more or less distinctly along the summit of the head in
