Remarks. — A. popeanellus, one of the first three acrolophids 

 described from the United States, is undoubtedly our commonest 

 and most widely distributed species and is one of the larger and more 

 robust acrolophids occurring in North America. It also exhibits 

 considerable variation in size and coloration. These four factors 

 explain why popeanellus is also the most heavily synonymized North 

 American acrolophid. 



A. popeanellus is closely related to klotsi, the two comprising a small 

 species group in general related to those acrolophids having elongate 

 labial palpi, setose eyes, laminate antennae, bifid uncus, and paired 

 gnathos. However, popeanellus and klotsi may be distinguished 

 from each other and from all other acrolophids on the basis of their 

 aedeagi and unci. The latter organ, in the impeanellus-klotsi group, is 

 distinctive in having its furcae abruptly directed or curved very 

 strongly ventrad. In popeanellus, these furcae, easily observable in 

 dried and undissected specimens, are characteristically expanded 

 into subtriangular plates. The genital characters of popeanellus 

 are consistent throughout my very large series and they are quite 

 distinct from those of all the other species treated here. 



I have not examined the type specimens of this species. Busck 

 (1903), in his report on Clemens' types of Tineina in the Academy of 

 Natural Sciences of Philadelphia, noted: 



Anaphora popeanella Clemens. Two types, both rubbed, one unspread and 

 without abdomen ; the other spread, and lacking the head and left wings. Clemens' 

 No. 11; alar exp., 28 mm. Like the present conception of Anaphora popeanella, 

 as determined by Walsingham and synonymous with scardina Zeller, and with 

 agrotipcnnella Grote. A specimen compared with the type is in the U.S. National 

 Museum. Habitat: Eastern United States. 



Darlington located one of these type specimens at Philadelphia, and 

 described it (in Htt., 1946) as: "popeanella Clem. Type. Right wings 

 only, poor condition, much rubbed, sex not determined." The com- 

 bined information that I have been able to gather in regard to pope- 

 anellus leaves no doubt in my mind as to the proper identity and cor- 

 rect concept of this species. The specimens of popeanellus in the U.S. 

 National Museum agree with my previous concept of this moth. In
