beyond the lower half of s. t. line extending to the outer margin from 

 the outward indentation of the s. t. line, and that is not common in 

 either sex. There is usually a dusky apical shade and a yellowish 

 line at base of fringes. Secondaries a little paler at base than 

 primaries, disc crossed by two or three dusky shade bands that some- 

 times form an obscure fascia. An extra-median double line, the 

 inner slender and often brown, the outer conspicuous, black, inwardly 

 diffuse. The lines diverge toward the costa and the space between 

 them tends to become and sometimes is completely dark filled. The 

 terminal space may be concolorous, may have a bluish gray band 

 through its middle or a leaden gray shading. Beneath dull yellowish, 

 more or less powdery, ranging from almost immaculate to forms with 

 a discal limule, a median dusky line and a t. p. and s. t. line on all 

 wings.

 and probably to the Rocky Mountains. 



This is one of the several different forms that has been in collec- 

 tions as calycanthata. It is sometimes named penna Morrison, cor- 

 rectly enough, and occasionally galbanata Morrison, which is not so 

 far out of the way. As a matter of fact I believe this to be the form 

 that Hiibner had before him and that served as the original of his 

 figure in the Zutraege. Careful comparison shows that no other 

 species answers all the requirements of the figures and that this species 

 does do so in all save a few minor details that are within range of 

 artistic error. Those very points which Mr. Morrison emphasizes in 

 his description of penna, notably the dark filling of s. t. space, are 

 well brought out by the figure, and so is the dusky basal area. I have 

 never seen any specimen with quite so well marked a yellow ring 

 around the reniform, but examples with a yellow edging are not in- 

 frequent. The irregular s. t. line w T ith the little dents on veins 3 and 

 4 is quite characteristic, and the secondaries I can match perfectly in 

 the series before me. 



The species figured under this name by Guenee is cingulifera 

 Walker, the mistake occurring through too great a reliance on the 

 dark basal area and pale reniform. Guenee seems not to have had 

 anything like the real species before him. 



As to the range of variation, that is considerable in both sexes, and 

 puzzling when it comes to making a separation from lineosa Walker. 

 In the typical form the basal and s. t. spaces are dark and there is 

 an upright median shade which fades outwardly. In such cases there 

 is usually a paler terminal area, and, in the male, more or less blue 

 powdering, so that there may be a resemblance to minerea or yet 

 more to the Colorado or rubi type. In rare eases there is a heavy in- 

 ward darkening from the s. t. space on both wings, leaving a pale 

 baud beyond the t. a. line, which gives those examples a very unusual
