Grote's original description follows: 



Anaphora mortipennella — cf. — Labial palpi reflexed, thrown back over and as 

 long as the dorsum of thorax, but not closely apphed, thickly scaled but less so 

 than in allied species, fuscous outwardly along the sides, dead whitish on the in- 

 side. Head and thorax above dead or dirty whitish. Primaries pale, dirty 

 whitish, with heavily sprinkled black scales on costal region at base, fading out- 

 wardly. A black scale patch at extremity of discal cell, and a larger one on sub- 

 median fold, below median vein, at about the middle of the wing; parallel with this 

 at base, a few black scales. There is a faint sprinkling of black scales over the 

 median nervules, and about internal angle are two or three better marked black 

 points on the margin. Four costal black marks before the apex, the first of these 

 above discal spot; other costal marks towards the base of the wing. Fringes 

 fuscous, faintly lined. Secondaries fuscous, much darker than, and strangely 

 contrasting with, the pallid primaries. Beneath both wings fuscous with ochrey 

 stains. The basal joint of labial palpi is prominently dark fuscous or blackish 

 outwardly. Expanse 25 mm. Central Alabama. June. 



Smaller than A. plumifrontella, and easily recognized by its pallid discolorous 

 fore wings, which are also a little more determinate at apices and internal angle 

 than usual. 



Male genitalia. — Vinculum typical, as in other species. 

 Tegumen glabrous; lateral arm of mediima length, margins well 

 sclerotized and sinuate, caudal portion markedly broad, remaining
