This species is evidently allied to T. lain, and differs only in the characters which 

 1 have stated above. It ranges from Namaqua Land across Matabele Land and the 

 Zambesi region, and thence north to Nyasa Land and the Lake Districts. Bishop 

 Hannington and Mr. Scott-Elliott have procured specimens in the neighbourhood of 

 the Victoria Nyanza, but in the many collections which I have received from my 

 friend Mr. F. J. Jackson I have not seen any examples of this species from 

 Equatorial Africa. Dr. Butler considers T. pseudetrida to be identical with T. pallcne, 

 but Mr. Guy Marshall thinks that it is a form of T. ecatjore. He writes: "This 

 species differs chiefly from T. ecar/ore in having a continuous black border along the 

 inner edge of the apical patch at all seasons. I have seen specimens from Nyasa 

 Land, Namaqua Land, and South Matabele Land." 



Dr. Butler, in his revision of the genus Teracolus, observes as follows : " I believe 

 that the species mentioned in my synonymy are identical, although the description 

 of the under surface of Westwood's type of T. pseudetrida does not correspond in every 

 detail with that of T. eiiiclus, and the female is described as having a sub-apical yellow 

 fascia, whilst the female of 2\ ciiictus has the apical area black, crossed by ill-defined 

 narrow ochreous dashes. Still, I believe that variation may account for these 

 discrepancies. One tiling is certain, that Westwood's insect must belong to the 

 T. (hurt/ group, and not to the singular mixed community in which Mr. Marshall has 

 placed it, for it undoubtedly has the orange apical patch of the male, black-bordered 

 internally. Assuming that my synonymy is correct, the species must be intermediate 

 between T.lai'mwiX T. iti/iuiiatiix, and must range from the Victoria Nyanza southward 

 to Nyasa Land, and thence to Tete on the Zambesi. The intermediate form has the 

 under surface washed with warm buff, and the dry-season form is small, with narrow 

 black borders, the black internal streak ill-defined, and the secondaries rosy on the 

 underside,"
