KEY TO THE GENERA OF NORTH AMERICAN 



Median vein of hind wing without pecten of hairs on the upper side; 

 maxillary palpi filiform. 

 Palpi with the second and third joints upturned. 



Proboscis absent or minute .......................... Aglossa. 



Proboscis well developed. 



Fore wings with vein 7 from 8 before 9 .......... Pyralis. 



Fore wings with vein 7 from 8 after 9 ...... Hypsopygia. 



Palpi obliquely upturned, the third joint porrect .......... Herculia. 



Palpi rostriform and downcurved at extremity ...... Omphalocera. 



Median vein of hind wing with pecten of hairs on upper side; max-

Aglossa cuprealis Hiibner. 



The species ranges from Maryland southward in the United 

 States. The specimens before me agree well with European 

 ones. 



Lloyds, Md., July 10, 1907 (H. S. Barber) ; Plummers 

 Island, Maryland, June 3 (A. Busck) ; District of Columbia, 

 July 2, 1888 (T. Pergande) ; Pittsburg, Pa., June 8 and 18, 



1906 (H. Engel) ; New Brighton, Pa., July 8, 1902 (H. D. 

 Merrick) ; "corn Pyralis, Treat;" Raleigh, N. C, June 28, 



1907 (H. S. Brimley) ; Eufaula, Ala. (C. V. Riley). 



Aglossa cuprina Zeller. 



Sir Geo. Hampson places this species in Pyralis, but my 

 specimens have the tongue aborted. Possibly Sir George has 

 made a different identification. If I am correct the species 

 is easily to be told from cuprealis by the strong exsertion of 

 the inner line on submedian fold, which contains an elliptical 

 dark patch, looking like an elongated replica of the discal 

 mark. 



Center Harbor, N. H. August 3, 1902 (H. G. Dyar) ; Plum- 

 mers Island, Md., June 5 to July 10 (Schwarz, Barber, Busck) ;

 tember 8, 1904 (H. McElhose) ; Texas, July 7 (Belfrage). 

 The last specimen was submitted to Ragonot in 1884, who 

 identified it as Aglossa cuprealis, but wrongly, in my opinion. 



Aglossa acallalis, n. sp. 



A small, frail species with very long fringes; reddish, powdered with 

 black as in cuprina Zell., the lines blackish, broad, edged with pale
