Remarks. — In addition to being widely distributed and fairly 

 common, yro-pinquus exhibits marked variation in size and coloration. 

 These factors undoubtedly account for its relatively large s3monymy. 

 The material representing this species was received on loan from 

 numerous sources. Good series containing both sexes are to be 

 found in the collections of the author, the American Museum of 

 Natural History, and Cornell University. 



Although not closely related to any other acrolophid, propinquus is 

 related to those species having elongate labial palpi, setose eyes, 

 laminate antennae, bifid uncus, and paired gnathos. The harpe and 

 the base of the uncus exhibit the most variation. However, the 

 aedeagus of propinquus has proved to be relatively uniform. Thus, 

 the characters to be found in the genitalia of propinquus are sufficiently 

 distinct from those of all other acrolophids treated in this work. The 

 variations exhibited by this species may indicate that it is in the 

 process of speciation. 



Photographs from Tams labeled "propinquus Wals., type" show 

 the adult cf and its genitalia. These photographs easily confirm the 

 identity of this species. Several slides of cT genitalia labeled "pro- 

 pinquus Wlsm." are in the U.S. National Museum. Upon examination 

 of these, I found that they agreed with my concept of this species. 



In his revision of 1887, Walsingham described Anaphora propinqua 

 and Anaphora tenuis as new species on pages 157 and 164 respectively. 

 He based his description of tenuis on seven cf cf collected in North 

 Carolina by Morrison and a single cf without locality in Zeller's 

 collection. The alar expanse for tenuis was listed as 24 mm. Wal- 

 singham 's illustrations of the cf genitalia of tenuis showed the uncus 

 and the cucuUus of the harpe in lateral aspect and the uncus alone in 

 dorsal aspect. Since 1887, tenuis has appeared in the literature as a 

 distinct species. 



Actually, there is nothing in the description and illustrations of 

 tenuis to indicate that it could not be propinquus. On page 157 of his 

 revision, Walsingham, in his key to the species of Anaphora, separated 

 the two essentially as follows: 



a. With supplementary processes on each side of the uncus . . tenuis, Wlsm. 



b. Without supplementary processes on each side of the uncus . propinqua, Wlsm. 



The "character" used above by Walsingham is neither consistent nor 

 of specific value. The lateral portions of the base of the uncus may 

 vary considerably within a series of specimens of almost any one 

 species, especially in the case of dried specimens. 



The type cf cT of both tenuis and propinquus are at the British 

 Museum. Photographs representing these types sent me by Mr. 

 Tams show moths in dorsal aspect and their complete genital capsules 

 in ventral aspect. These two sets of photographs undoubtedly
