ENTOMOLOGY. 34 1 



the most important part of his collection, I have given a complete 

 catalogue of them in the following pages. These insects abound in 

 certain districts, and in Mr. Trimen's work on South African butter- 

 flies, published in 1862- 1866, as many as 197 different species are 

 recorded, after deducting 29 species inserted incorrectly ; whilst in his 

 new work (of which vols. i. and ii., published in 1887, include the 

 families Nymphalid^e, Erycinid^e, and LyCjENID^e) he expects, 

 when it is completed, to bring the number of known South African 

 forms up to about 3S0. 



Species of the families Danaid^e, Satyrid.<e, Acr/eid^e, Nym- 



PHALID^E, LlBYTHEID^E, LYCLENID/E, PlERIDiE, PAPILIONID^E, and 



Hesperiid^e, occur in each of the three divisions into which Mr. 

 Wallace has divided the continent of Africa south of the Great Desert ; 

 but of the families Elymniid^e and NEMEOBiiDiE no species have 

 been found in the South African sub-region, which, however, possesses 

 seven genera peculiar to itself,— two belonging to the Satyrid^e, one 

 to the AcRjEID/e, three to the LyCjENID^e, and one to the HesperiiDjE. 

 The beautiful species of Zeritis are also peculiar to this sub-region, 

 one additional species only inhabiting West Africa. 1 



Of the Danaid^E, species occur in each of the four Ethiopian sub- 

 regions. Of the Satyrid^e, which also occur in all the four sub- 

 regions, Gnophodes, Leptoneura, and a few other small genera are 

 exclusively African. Of the Elymniid/E, which are characteristic of 

 the Malayan and Moluccan districts, one species also occurs in 

 Ashanti. The Morphid^e, Brassolid^e, and typical Heliconiid^e 

 do not occur in Africa ; the ACR/EID^E, on the contrary, have their 

 metropolis in this continent, which produces more than two-thirds 

 of all the known species. Of the Nymphalid^e, which is the largest 

 and most universally distributed family of butterflies, species occur in 

 all the sub-regions of Africa. There are fourteen genera of these 

 butterflies exclusively African, including Lachnoptera, Amphidema, 

 Catuna, Euryphene, Romaleosoma, Aterica, and Harma. Libythea 

 (constituting the family Libytheid^e) is widely distributed, and occurs 

 in Western Africa and Madagascar, and one species has been dis- 

 covered in Eastern and South-eastern Africa. The family Nemeobiidce 

 is represented in West Africa and Madagascar, but not in South Africa. 

 No representative of the family Erycinid^E (proper) occurs in the old 

 world or Australia. The LyCjENID^E, on the other hand, are found in 

 all the sub-regions of the globe, the genera Pentila, Liptena, D' Urbania^ 

 Axiocerces, Capys, Phytala, Epitola, Hewitsonia, and Deloneura being 

 peculiar to Africa. Of the family PlERID^E, Teracolus and Pseudo- 



Butler (P. Z. S., 1876), a matter which has now been set right in the succeeding text. Acrcea 

 Acronycta of the first edition has also now been referred to A. Stenobea, Wallengren, and 

 Acrcea Aitzfihimalla and A. Dirccea both to A. Caldarena, Hewitson. — Ed.] 



1 From recent investigations a large number of genera have been formed out of sub-divisions 

 of the older genera given in the text of the first edition, so that the genera thus formed 

 have considerably increased the number of these groups peculiar to Africa, as stated above.
