AMERICAN LEPIDOPTERA. 7 



spots have a somewhat luteous shading that renders them obvious 

 if not contrasting. The harpes of the male genitalia are very 

 broad at base, narrow abruptly at about the middle, then broaden a 

 little and are roundedly oblique to an acute superior tip, no part of 

 which is set with spinules. The clasper is at the middle of the 

 harpe, long, slender, very strongly curved. The corneous median 

 ridge has a rather short, stout, flat, pointed central tooth and a 

 somewhat longer and broader process at the lower angle of 

 the tip. 



Itata is a much smaller species, of a soft powdery gray which ob 

 scures, while it leaves traceable, most of the ordinary markings. 

 There are no contrasts, and the only features that are at all relieved 

 are, a little diffuse black spot in the lower portion of the reniform, 

 and a similar patch in the submedian interspace where the t. p. line 

 should be. No male has been seen. 



Fagina is larger than either of the preceding and is a much paler 

 gray ; white powderings over the primaries and especially in the cos- 

 tal region, giving it a brighter appearance than usual in the genus. 

 The veins are very narrowly black marked, and in the interspaces 

 are blackish teeth, forming disconnected parts of the usual lines. 

 The ordinary spots are practically lost, though the orbicular may be 

 defined as an oblique and very irregular concolorous spot in some 

 examples. The harpes of the male are long and narrow, tapering 

 from outer fourth to an elongate narrowly rounded tip, which is not 

 set with spinules. The clasper is at the middle, rather moderate in 

 length and only a little curved. The oblique ridge has a broad 

 tooth at the middle and a long, curved, pointed process extending 

 from the middle of the oblique ridge, narrowing to a little be\ond 

 the rounded tip. 



Longior equals the preceding in size, but is broader wins^ed and 

 seems larger, more robust. It is darker gray, much more strigate, 

 and here a black basal streak is sometimes indicated. There is, 

 indeed, a black streaking throughout the wing, the most obvious 

 being through the submedian interspace and obliquely from below 

 the reniform to below the apex. The latter is usually accompanied 

 by a smoky brown shade which umy extend throughout the centre 

 of the wing. The male genitalia differ markedly from all previous 

 forms. The long, narrow harpes have the upper edge broadly 

 corneous, and at tip this is broadened and irregularly emarginate.
