OF WASHINGTON. 317 



venular dots parallel with the outer margin. Reniform obvious, though 

 diffuse, inferiorly clouded at the end of the cell, and sometimes marked at 

 its upper border. Secondaries pale yellow in the female ; darker, with a 

 somewhat fuscous tinge in the male. Beneath, yellowish in the female, 

 smoky in the male; disc of primaries darker and with a vague outer line; 

 secondaries powdery along the costa. Abdomen concolorous with the 

 secondaries. 



Expanse. Male, 1.20-1.40 inches = 30-35 mm. 



Female, 1.20-1.68 inches =^= 30-42 mm. 



Habitat. Kittery Point, Maine, in September (Thaxter) ; 

 Hamilton, Ontario ; Winnipeg, Manitoba, August 31 (Hanham) ; 

 Cartwright, Manitoba (Heath) ; Volga, South Dakota (Truman) ; 

 Wisconsin, Iowa, Nebraska (Coll. div.) ; Champaign, Illinois, 

 July 28, at electric light (Forbes) ; Chicago, August 3 ; Eliza

It is probable that the species will be found to occur through 

 out the northern and middle United States and throughout the 

 British possessions to the Rocky Mountains, wherever conditions 

 are favorable. Forty-three examples are before me, of which six 

 only are males, and none are from any southern locality or from 

 the Pacific Slope. 



I have seen males that are very like the females in maculation, 

 but darker in ground, and from that they vary to an almost uni 

 form red-brown, with vague venular shadings. In the female 

 there is not much variation ; there may be an addition of reddish 

 to the ground color, and there is more or less difference in the 

 amount of contrast along the median vein and in the terminal 

 space, but on the whole there is an obvious similarity throughout 

 the long series before me. The difference in size is greater than 

 the record indicates, for while there are some females as small as 

 any males, the average female is larger than the largest male. 

 Of the 37 female examples, 27 exceed in size the largest male of 

 my series. I am not aware that this species has been actually 

 bred, and know of no records to that effect. The frontal process 

 is absolutely and relatively shorter than in oblonga, and, seen 

 from the top, the margin is broader, almost explanate, the edge 

 much more finely denticulate. The tip is obtuse, entire and a 

 little turned down. Seen from the side the lower half of the 

 front is extended, obviously to the tip of the projection, forming 

 a more perfect cone. 



In the female, the lateral pieces that bend upward from the 

 lower margin have the tip rounded or obtuse, not in any way 

 emarginate or excised ; and this character holds true in all the 

 specimens examined by me. Ordinarily, unless the specimen 

 is very fresh and has all the anal vestiture intact, the form of 

 these pieces can be discerned without much trouble.
