named the species after the collector, who died in 1885. Since 1887, 

 morrisoni has consistently appeared in the Mterature as a distinct 

 species. Walsingham's illustrations of the cf genitalia of morrisoni, 

 showing the uncus and the cucullus of the harpe in both lateral and 

 dorsal aspects, are essentially the same as his corresponding figures of 

 the cf genitalia of popeanellus. On the preceding page of his revision, 

 Walsingham had separated the two species as foUows: 



1. Points of the uncus distinctly separate — popeanella. 



2. Points of the uncus closely approximate — morrisoni. 



This difference is easily absorbed in the range of intraspecific variation 

 exhibited by popeanelhs. 



The type cf is at the British Museum (Natm^al History), from 

 which tarns has sent two photogTaphs, labeled "morrisoni Wals., type 

 cf." These show, through a dorsal view of the pinned moth and a 

 ventral view of its entire genital capsule, that it is shnply a small but 

 typical Floridian specimen of popeanellus. Thus, morrisoni (Walsing- 

 ham) should be considered a new synonym of popeanellus (Clemens). 



Beutenmiiller's manuscript name, Acrolophus conjusellus, first 

 appeared in print in 1891 in Smith's checklist, where it appeared as a 

 valid species. Dyar (1900) referred to the name in Smith's list as 

 "confusellus, Beut. (ined.)," indicating it was unpublished. In addi- 

 tion, Dyar validated conjusellus by properly synonymizing it with the 

 older species "Anaphora popeanella, Clemens," so that it emerged as 

 Anaphora conjusellus Dyar. He then, however, treated it as a form, 

 stating: 



The form conjusellus is smaller than the usual form, the ground colour lighter 

 and more purplish, the dark marks stronglj^ relieved. In genitalia there is no 

 marked difference. The form differs from -popeanella about as much as Acrolophus 

 cervinus, Wals., does from A. plumifrontellus, Clem. U.S. Nat. Mus., type No. 405. 

 Georgia (Beutenmiiller's type). 



It is obvious from the statement that Dyar had Beutenmiiller's 

 manuscript type specimen (chirotype) available for study, and it is 

 interesting to note that conjusellus and cervinus actually are synonyms 

 of popeanellus and plumifrontellus, respectively. In 1903, the combi- 

 nation appeared as a distinct and valid species in Dyar's checldist; 

 presumably, the statement quoted above was now intended to serve as 

 the basis for considering conjusellus a separate species. Thus, conju- 

 sellus was elevated from chironym to synonym to form to species. 

 vSince 1903, conjusellus has consistently appeared in the literature as a 

 distinct species. Forbes (1923, p. 121) listed "conjusellus Beuten- 

 miiller" as a synonym of popeanellus but also treated "conjusellus 

 Dyar" as a separate species. 



There is no indication that BeutenmiiUer actually did pubHsh a 

 description of conjusellus. He invariably described his new species in
