Another genus of tHis family, Jansenia, iscommon to South Africa and South India.In the large family of Carabidae,or ground-beetles, there are17 peculiar South African genera, the most important beingCrcpidogaster, ffytrichopus, Arsinoe, and Piezia.Three othersEunostus, Glyphodactyla, and Megalonychus—are common toSouth Africa and Madagascar only. There is also a genus iacommon with Java, and one with Australia.Of Lucanidae, or stag-beetles, there are 3 peculiar genera ; ofCetoniidse, or rose-chafers, 14 ; and of Buprestidee, 2.In the great family of Longicorns there are no less than 67peculiar genera—an immense number when we consider that thegenerally open character of the country, is such as is not usuallywell suited to this group of insects. They consist of 5 peculiargenera of Prionidse, 25 of Cerambycidae, and 37 of Lamiidae.Summary of South-African Zoology.—Summarizing these results,we find that South Africa possesses 18 peculiar genera ofMammalia, 12 of Birds, 18 of Eeptiles, 1of Fishes, 7 of Butterflies,and 107 of the six typical families of Coleoptera.Besidesthis large amount of speciality it contains many other groups,which extend either to West Africa, to Abyssinia, or to Madagascaronly, a number of which are no doubt to be referred asoriginating here.We also find many cases of direct affinity withthe Oriental region, and especially with the Malay districts, andothers with Australia ; and there are also less marked indicationsof a relation toAmerica.Atlantic Islands of the Ethiopian Region. St. Hehna.—Theposition of St. Helena, about 1,000 miles west of Africa and 16°south of the equator, renders it difficult to place it in either ofthe sub-regions ; and its scanty fauna has a general rather thanany special resemblance to that of Africa. The entire destructionof its luxuriant native forests by the introduction of goatswhich killed all the young trees (a destruction which was nearlycompleted two centuries ago) must have led to the exterminationof most of the indigenous birds and insects. At present there isno land bird that is believed to be really indigenous, and but one
