Sept.,i9ioj Smith: North American Agroperina. 143 



the true cxornaia, and Hampson was right in pointing out my error; 

 Inxt the form is not inficita Wlk. ; it grades insensibly into the form 

 which is described and figured by Hampson as morna. Dr. Barnes 

 has a magnificent series of examples from the Yellowstone, Colorado, 

 and various British xAmerican points and two series of these can be 

 separated. I have called one of these species indela, and the other 

 Ihicosa. 



An off-shoot from the above, but I think distinct, is what I believe 

 Hampson refers to as " Ab. 2," of A. morna. "Head, thorax and 

 fore wing deep rufous ; abdomen and hind wing more tinged with 

 rufous." I have called this pendina, and believe all the forms now in 

 collections, belonging to this series, can be placed under one or the 

 other of the above names. 



Agroperina inficita Wlk. = belangeri Morr. is the darkest and best 

 marked species of the series. The primaries are dark luteous brown 

 and the secondaries dark smoky, almost blackish. The maculation 

 of the primaries is complete, the median lines single and the median 

 shade well-defined, rusty brown, strongly angulated on the reniform. 

 The s.t. line is of the ground color, relieved against the darker ter- 

 minal space and preceded by a darker shade in the s.t. space. The 

 ordinary spots are present, the orbicular feebly marked, the reniform 

 always dusky inferiorly, sometimes all dark and usually more or less 

 definitely outlined by paler scales. 



The antennae of the male have the joints slightly marked, ciliate, 

 the cilia somewhat grouped into tufts, without longer lateral bristles. 

 Tliere are no obvious dorsal tuftings on the abdomen and the vestiture 

 consists of flattened hair without obvious scaly admixture. The flat- 

 tening of the hair is mostly at the tip, giving the individual hair some- 

 what the appearance of a miniature long-handled shovel. 



There is very little variation in this species so far as my material 

 extends; the coloring is very uniform and the relative relief of the 

 spots and lines shows only a slight difference. All the material seen 

 by me comes from Quebec or Newfoundland, and all the dates are 

 in August. 



The genitalia of the male do not differ in any very important fea- 

 ture from those of Intosa. The harpes are somewhat less angulated, 

 and the constriction before the dilated tip is less marked. The other 

 dift"erences can be more easily appreciated by comparing the figures 

 than from descriptions.
