256 ZOOLOGICAL GEOGRAPHY. [part hi. 



are many interesting forms of Nymphalidie, Lycffiuidse, and 

 Papilionidse. The peculiar or characteristic forms are Amauris 

 (DanaidiB) ; Gnophodes, Leptoneura, Bicyclus, Hetero^jsis and 

 Coenyra (Satyridffi) ; Acrcca (Acraeida) ; Lachnoptera, Precis^ 

 Salajnis, Crenis, Godartia, Am2)hidenia, Psendacrcea, Catitna, 

 Eurijjjhcnc, Romalceosoma, Hamanivmida, Atcrica, Harma, 

 Mc7icris, Charaxes, and Philognoma (Nymphalida:^) ; Pentila, 

 Liptcna, Durhania, Zeritis, Capyfi, Phytala, Epitola, Hewitsonia 

 and Peloneura (Lyctenida^) ; Pseudopontia, Idmais, Tcracolus, 

 Callosune. (Pieridiie.) ; Ahantis, Ceratrichia and Gaprona (Hes- 

 peridse). The total number of species known is about 750 ; 

 which is very poor for an extensive tropical region, but this 

 is not to be wondered at when the nature of mucli of the 

 country is considered. It is also, no doubt, partly due to our 

 comparative ignorance of the great equatorial forest district, 

 which is the only part likely to be very productive in this 

 order of insects. 



Colcoptcra. — In our first representative ftimily, Cicindelidte 

 or tiger-beetles, the Ethiopian region is rather rich, having 13 

 genera, 11 of which are peculiar to it; and among these are 

 such remarkable forms as Manticora, Myrmccoptcra oxni Dromica ; 

 with Megacephala, a genus only found elsewhere in Australia 

 and South America. 



In Carabidte or carnivorous ground beetles, there are 

 about 75 peculiar genera. Among the most characteristic 

 are Anthia, Polyrhina, Graphiptcrus and Piezia, which are 

 almost all peculiar ; while Orthogonius, ffexagonia, Macrochilus, 

 Thyreojyierus, PJudema, and Ahacdus are common to this and 

 the Oriental region ; and Hypolithus to the Neotropical, 



Out of 27 genera of Buprestida3, or metallic beetles, only 6 are 

 peculiar to the region, one of the most remarkable being Poly- 

 bothrus, confined to Madagascar. Sternocera and Chrysochroa are 

 characteristic of this region and the Oriental; it has Julodis in 

 common with the Mediterranean sub-region, and Belionota 

 with tlie Malayan. 



The region is not rich in Lucanidse, or stag-beetles, possessing 

 only 10 genera, 7 of which are peculiar, but most of them con-
