“Mr. Trimen (‘South African Butterflies,’ vol. III, 1889, 
p. 181) has drawn attention to the resemblance borne to 
Mylothris agathina, Cram., and Selenois ianthe, Doubl., by 
certain forms of the female Leuwceronia argia, Fabr. The 
female of this Pierine is extremely variable, and the object of 
the present exhibit is to show that each of its diverse forms is 
associated in aspect with one or more species of JMvylothris, 
Lelenois, Pinacopteryx or Phirissura—all these being genera 
whose affinity with Leuceronia is remote. 
“The following are the forms now exhibited, together with

“These examples do not exhaust the list of forms of LZ. argia, 
? , which resemble other Pierine species ; for besides the black 
and yellow f. zdotea, Auriv., which is the form noticed by 
Trimen for its resemblance to Belenois ianthe, there is a 
modification of f. varia, Trim., with a yellowish hind-wing like 
No. 6 supra but without the basal flush, which falls into 
association with a form of the female Pinacopteryx pigea,
