After examination of specimens of this species in 1904 Doctor Dyar 

 advised me that it belonged to neither the Epipaschiinae nor the 

 Pyralinae, where it had been placed by Hulst and Fernald, but should 

 be included in the subfamily Crambinse, suggesting that it was 

 " n. gen. et sp." Shortly afterwards, when visiting the Hulst collec- 

 tion at New Brunswick, he saw Hulst's type, thus securing the specific 

 name. 



The species seems to be very abundant in southwestern Arizona. 

 More than one hundred specimens have passed through my hands 

 from both desert and mountain collections. Among the localities are 

 Yuma County, Arizona, desert, March 26 to April 10, J. B. Smith; 

 Yavapai County, Arizona, March 10-31, J. B. Smith; southern 

 Arizona, August 1-15, O. C. Poling; Baboquivaria Mountains, Pima 

 County, Arizona, July 15-30, O. C. Poling. 



The species is somewhat variable in the intensity of the markings 

 and of the light and dark shades. The females have dark gray or 

 dark cinereous hind wings, while these wings in the male are whitish 

 gray. The fore wings of the males are also lighter generally than 

 the other sex. The general appearance of the fore wing is a mottled 

 gray, with a conspicuous triangular whiter patch on upper half of 

 wing and touching costa from middle to outer fifth ; the males average 

 from 22 to 26 mm. and the females from 25 to 32 mm. 



This species seems to have been entirely ignored by both Ragonot 

 and Hampson in the seventh and eighth volumes of Romanoff's 

 Memoires sur les Lepidopteres. a It does not appear in the specific 

 index of either volume, nor could I find it in the text or footnotes ap- 

 proximating the place it should be if Hulst's generic position had been 

 followed. 



PRIONAPTERYX STEPHENS and allied genera. 



The species included in the four genera below bear a strong 

 superficial likeness to each other and readily form a small subfamily 

 group in the Crambinse which are not easily confused with any other 

 species or genera of the large family. Except in one genus (Surat- 

 tha) they are all characterized by an incision in the termen of fore 

 wing at end of vein 5, or in more modified species the termen below 5 

 is well cut away, leaving a projection on the upper half of wing. 



In markings the species are of combinations of cream white, 

 ochreous to dark brown or grayish brown; the inner line is usually
