334 Mr. E. G. Joseph on the Rhopalocera 



(see note on 108 and 97, Ann. & Mag. Nat. H'sf. ser. 7, 

 vol. xiii., Apiil 1904, pp. 321 & 319 respectively) ; 



(3) The Ithomiinae with transparent wings, such as Ptero- 

 wymia euritea, Pteronymia kemixanthe, and Heterosddct 

 yanetta, as the following note, in the Cat. pi. Braz. MSS. 

 701-3461, shows : — "1287. Ex Liatrideis. Plantaherbacea 

 erecta 5-ped. floribus albis. Hanc quoque vidi in Mina3 

 Geraes copiote, ubi frequentatur a variis Papilionibus 

 ex genere P. Hortce, alis diaphanis." * We also find 

 under the date Feb. 24, 1826, when Burehell was collecting 

 " Between the foot of the [Organ] Mountains and Frechal," 

 the following entry : — " 2577. Syngenesia. Flores albi . . . 

 Delecius papilionum variarum, sed praesertim ex genere 

 P. hortce." * The name " Ilorta " occurs in reference to 39, 

 and the white- flowered Liatridea under 36 l , but the above 

 more detailed descriptions from the Oat. pi. Braz. had not b^en 

 found when the account of these early numbers, 38, 39, &c. 

 was prepared for publication. 



(4) The abundant South-African Acrcea horta, Linn., 

 captured in large numbers by Burehell. There are now in 

 the Hope Department at least 15 specimens taken by him, 

 Jan. 1, 1815, at the Buffeljaght's River, near Swellendam. 



On his return home Burehell named his African collection 

 by comparison with the Banksian cabinet, then in the rooms 

 of the Linnean Society, now at the British Natural History 

 Museum. His notes exist at Oxford, and show that he 

 obtained from this source the name " P. Ilorta " for the 

 common S. African Acrcea. The manuscript bears the 

 following interesting heading : — 



"The following notes are the result of a collation of 

 the whole of my African collection of insects, with the 

 Banksian Cabinet (now belonging to the Linnaean Society) 

 the greatest part of which is named in the handwriting of 

 Fabricius. 1823 to 1824." The words " but I fear some 

 labels had been misplaced." were added at a later date. 



In the Banksian cabinet it can now be seen that the 

 African Acrcea horta stands as one of the group " Heliconii," 

 in which are included not only Acreeinae, but Heliconiina? and 

 Ithomiinae — in fact, all the subfamilies to which Burehell 

 applied the term " Horta " or of which he wrote " belonging 

 to the genus of P. Horta." The evidence now brought 

 together makes it clear that by "Horta" Burehell meant to 

 imply a place in the Fabiician " Heliconii," the group headed 

 by Acrcea horta, a species well-known to him before he started,
