yellowish, both mesially excurved and feebly dentate, but smooth and 

 even in comparison with the lines of the other species; fringes silky 

 gray. Hind wing pale grayish, with a darker irregular mesial line far 

 removed from the margin. Expanse, 16 to 20 mm. 



Three specimens, Williams, Arizona, July 9 and 19 (H. S. 

 Barber) ; Ashfork, Arizona, June 18 (H. S. Barber). 

 Type. No. 11924, U. S. National Museum. 



Genus PYRALIS Linnaeus. 



Pyralis farinalis Linnaeus. 



Distributed throughout the United States. 



Pyralis costiferalis Walker. 



I have three specimens that agree well with Walker's de- 

 scription. 



New Brighton, Pa., July 2, 1905 (H. D. Merrick) ; Pitts- 

 burg, Pa., June 23, 1905 (H. Engel) ; (C. V. Riley). 



Pyralis disciferalis, n. sp. 



Fore wing reddish ocherous, irrorate with blackish; costal edge 

 blackish except where cut by the lines ; discal spot large, blackish, sub- 

 quadrate; lines ocherous, slightly intensified on the costa, strongly 

 edged toward the median space with blackish, the inner slightly angled 

 on median vein and produced inward on submedian fold, the outer 

 mesially excurved, obscurely dentate; a row of black points at the base 

 of the fringe. Hind wing ocherous, reddish shaded, usually with an 

 extra mesial dark line and row of dots in the fringe. Expanse, 16 

 to 23 mm. 



Twenty-four specimens, Plummers Island, Maryland, June 

 5 to August 1 8 (Schwarz, Busck, Barber, Warner) ; Pitts- 

 burg, Pa., July 20, 1906 (H. Engel) ; New Brighton, Pa., 

 June 20, 1902 (H. D. Merrick) ; Chicago, 111. (A. Kwiat) ; 

 Travilah, Md. (F. C. Pratt) ; Black Jack Springs, Texas (W. 

 Barnes) ; Kerrville, Texas, May, 1900 (H. Lacy) ; Somerville, 

 S. C., April (R. Ottolengui). 



Type. No. 11925, U. S. National Museum. 



Allied to P. costiferalis Walk., but the costal markings are 

 not more developed than the cross-lines. Especially the basal 

 costal mark does not exceed the subcostal vein, whereas in 

 costiferalis it extends to the median vein. 



A specimen was sent to Prof. C. H. Fernald in 1901, but still 

 remains with him unidentified. I venture to enforce the 

 statute of limitations on a seven years basis and identify the 

 species myself.
