other ; but they are absolutely distinct from those of Europe, al- 
though they may be generally classed in the same genera, as 
well as in some of those of Africa. We do not there find any 
species of Graphiptera^ Ahis, Scaurus, Fimelia, Lepidium, or 
JErodius, genera of which Nature appears to have confined to the 
southern and westernparts of the Ancient Con tine nt. Eab 
cius has assigned to the Eas tindirs some species of Brachy- 
cerus ; but I have never been able to discover a single indi- 
vidual of that genus among the numerous collections which 
have been formed there. The genus Anthia occurs in Ben- 
gal, but further than that they do not find a single spe- 
cies. 
The island of Madagascar, in respect to its natural families of 
insects, is allied in some points to Africa. But its species are 
very distinct, and many of them have no analogies in that coun- 
try. The islands of France and Bourbon, offer also vestiges of 
the same affinity. The insects of these colonies appear, however, 
in general, to keep closer to those of the East Indies ; their num- 
ber is very limited. 
Although the entomology of New Holland has a peculiar 
type, it is, nevertheless, composed in a great part, of species analo- 
gous to those of the Moluccas and the south-east of India The 
genus Mylabris^ of which the species are so abundant in the 
south of Europe, in Africa, and in Asia, does not appear to pass 
beyond the island of Timor. If such be the case, New Holland 
would bear a trait of resemblance to America. In like manner, 
we find there the genus Papalus^ of which the species are known 
more particularly to inhabit the New World. I suspect that the 
natural productions of that western hemisphere, considered under 
the relation of generic groups, are more allied to those of the 
east of Asia than to our own. It is known, that the Marsupial 
animals are confined to the eastern extremity of the Ancient Con- 
tinent, and that they again appear in the New. I could produce 
other examples, of which some might be taken from the class of 
Crustaceous animals. 
* New Holland is less rich, its soil, so far as it is known, being more dry, and 
not so woody.
