is below upper third; before and behind it on costa are large tri- 

 angular white streaks; on each side of the mottled gray and brown 

 apical spots are smaller white spots. Below the angle of the sub- 

 terminal line the margin is white, outwardly marked with a row of 

 four or five black dots. Dorsal edge narrowly white; beyond the 

 middle the extreme edge is gray, below the white line. Beyond end 

 of cell the veins are overlaid with silvery white, but not extending to 

 subterminal line. Cilia pearly gray, white at base. 



Hind wing whitish gray, darker along costa and in apex, underside 

 the same. Underside fore wing dark gray, termen white, veins 

 dotted with black. 



Four specimens, High Bridge, Alberta (Thos. Baird), Regina, 

 July 21, all received from Mr. T. N. Willing; Redvers, Saskatche- 

 wan, A. J. Croker. 



Homotype in Author's collection. 



I had the foregoing description written, under a new name, when 

 a visit to the Hulst collection at Xew Brunswick showed that my 

 supposed new species was trichusalis. Hulst's type is in excellent con- 

 dition, and I hardly see how it could have been made a synonym of 

 dumetellus Hiibner. The median silver line of the latter ends at 

 outer third ; beyond it and below it is an elongated silver spot ; in 

 trichusalis the silver streak extends in a continuous line, nearly touch- 

 ing the subterminal line, at the outer sixth or seventh of the wing. 

 I have no European specimens of dumetellus, but the figures in both 

 British Pyralides by Leech, 1886, and Lepidoptera of the British 

 Islands by Barrett, 1905, show this character. It is also shown in 

 Fernald's fig. 2, PI. ITT, Crambidse of North America. I feel en- 

 tirely safe in restoring Hulst's name to specific rank." 



CRAMBUS YOUNGELLUS, new species. 



Expanse, 17-18.5 mm. 



Palpi, head, and thorax white, labial palpi on exterior surface, 

 maxillary palpi at base, and patagia shaded with ochreous brown; 

 antenna grayish white, abdomen white, with a slight yellowish tinge, 

 anal tuft darker; legs white, dusted and banded with brown. 



Fore wing bright ochreous brown, a darker shade along costal edge. 

 The usual silvery white stripe is very broad to middle of wing. To 

 this point its lower edge is bounded by the fold, and from which it 

 angles from both upper and lower edges to a point ending midway 

 between veins 5 and 6 and one-third the distance from end of cell to 

 termen. On the inner half of wing the costa is dark gray brown, in 



a Since the above was written I have received a long series of European speci- 

 mens of dumetellus, and they fully confirm this opinion; in fact, I have seen no 

 specimens from North America which could possibly be referred to this species, 

 and believe it should be stricken from our lists.
