150 Lord Walsingham's revision of the 



Lederer.* We may thus safely conclude that bombycina 

 and plumifrontella are one and the same species. 



Although plumifrontella; heing the first species de- 

 scribed by Clemens under his genus Anaphora, has been 

 regarded as his type, it does not so well agree with his 

 generic description in the matter of serrate antennae as 

 popeanella, a fact which he emphasises by putting a 

 heading in italics above the description of the latter 

 species, " Antenna of $ distinctly serrated beneath." It 

 will therefore be convenient to regard popeanella as the 

 type of the genus Anaphora, and to place plumifrontella 

 in Acrolophus under the distinguishing character of 

 " Antennse simple, compressed, or slightly serrated at the 

 ends."t Arcanella falling into Ortholophus on account of 

 its erect palpi.

" $ . Labial palpi reflexed, thrown back over and as long as the 

 dorsum of thorax, but not closely applied, thickly scaled, but less 

 so than in allied species, fuscous outwardly along the sides, dead 

 whitish on the inside. Head and thorax above dead or dirty 

 whitish. Primaries pale, dirty whitish, with heavily sprinkled 

 black scales on costal region at base, fading outwardly. 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, 2.3 mm. Central Alabama. June." 



Professor Zeller (Verh. z.-b. Ges. Wien, 1873) mentions his 

 doubts about this South American female, but remarks that his 

 scruples were removed by the fact that •'the wing-veins correspond 



exactly" with those of the male from Massachusetts.
