thence obscurely dentate to margin, is inwardly outlined with darker 

 brown ; a short white line from costa at apex to termen. In the middle 

 of the outer margin is a small white ocellic dot, just below the incision? 

 above is a short dark bar, and before it the ground colour is heavily 

 sprinkled with darker scales. Cilia sordid white, divided by a brown line 

 above the incision. Hind wings pale cinereous, with a darker shade 

 before the cilia, which are sordid white, with a slightly darker basal line. 



Five specimens, four collected by Prof. F. H. Snow, Baboquivaria 

 Mountains, Arizona, and one Huachuca Mountains, Arizona, O. C. 

 Poling. Co-types in Kansas Academy of Sciences and my collection. 



Nearest to achatina, Zell., but can be readily separated by the two 

 fine white lines on costa just before apex, which are lacking in achatma, 

 and in their place is a rather broad white streak. The four specimens 

 from Prof. Snow are rather badly rubbed, especially over the middle of 

 the wing, causing an impression of a broad white median band. 



Fhitella yumaella, sp. nov. — Expanse, i6 to 27 mm. 



Head with loose scales ; antennae simple, basal joint with dense flaps ;
