4232 On the Geographical Distriibution of Insect^^ 



Canaries, on the contrary, liave been very fully explored, par- 

 ticularly since the voyage of MM. Web and Berthelot, and 

 they are found to have an entomology absolutely analogous 

 to that of the Mediterranean region, and often identical in 

 regard to species. 



__ j 18th, Senegambia, bounded on the north by the river Sene- 

 gal, on the south by a line drawn from Bissagos, on the west 

 by the ocean, and without determinate limits on the east. The 

 principal parts whose entomology has been explored, lie along 

 the river Senegal as far as the country of Galam, and the sea 

 coast. It is a very rich region, having perhaps more relation 

 in its insect productions to Abyssinia and Nubia than to the 

 following region. It possesses, at the same time, a very great 

 number of peculiar species belonging to all the orders. 



19th, Coast of Guinea, from Bissagos as far as the river 

 Gabon, a region whose climate is so fatal to Europeans as 

 almost to cut it off from the researches of naturalists, but 

 which is one of the most remarkable on the globe in relation 

 to its entomology. All its productions of this class have a 

 fades peculiar to them, although they are allied to the spe- 

 cies of Senegambia and the Cape of Good Hope. It pos- 

 sesses numerous Lepidoptera of the highest beauty, particularly 

 Papilio, Danais, Acrea, and the Nymphalides. It is the native 

 county of Charaxes ; and among the Coleoptera, Teflus, 

 Goliathus, &c. 



20th, Congo, a country little known in the light we are now 

 considei'ing, but it appears not to be so rich as the preceding, 



21st, Cape of Good Hope, as far as the tropic of Capricorn, 

 and consequently including a gTeat part of Cafraria. This 

 region is better known than any other in Africa, and it is 

 very rich, but only in Coleoptera. It is the native country of 

 Manticora, Platichyles, Dromica, of large species of Moluris 

 and Brachycerus, of a great number of Jalodis and Lepitrix, 

 Anysonyx, Monochelus, which replaces Amphicoma of the 

 Mediterranean region, &c. Its Lepidoptera, of moderate' 

 number, consist of some beautiful kinds of Papilio, Danais, 

 Nymphalides, and Satyrus. The genus Pneumora, one of the' 

 most remarkable of the Orthoptera, has only been found here.' 



The insects of all the central parts of Africa are wholly'
