ON THK GEOGRAPHY OF ANIUAIiS. 



Scarabus of De Montfort is restricted to certain of the 

 Asiatic islands ; while among the slugs, or shelless Tes- 

 tacea, the genus Onchidium, as defined by Dr. Buchanan, 

 appears to characterise this part of the world. 



(74.) To enumerate the tribes of insects, and of 

 the other annulose animals, is altogether impossible. It 

 will be sufficient to mention, that the entomology of 

 Southern Asia presents us with some few of the most 

 common butterflies dispersed over Europe. The Papilio 

 Podaliriush., Eurymus Edusa Sw., Cynthia Cardui, and 

 Vanessa Atalanta, have been sent from the mountains 

 of Nepal, a region, however, — from the peculiarity of its 

 productions, — which might more properly be considered 

 within the limits of, or at least bordering upon. Central 



Asia. But these, after all, 

 are but rare and nearly so- 

 litary exceptions to the very 

 general dissimilarity between 

 the insects of the two con- 

 tinents. The entomology of 

 Africa assimilates much more 

 closely to that of India; 

 and the latter contains se- 

 veral genera, particularly 

 among the lepidopterous in- 

 sects, which are precisely 

 the same as those of tropical 

 America. The Indian is- 

 lands^ but more especially Amboyna, appear to be 

 richer in insects, if we may judge from such as have 

 18 ,s?g^ ^5=^^ been sent to Europe, than 



the continent. That rare 

 and lovely butterfly, the 

 Amphrisius Priamus Sw. 

 {Jig. 17-)j vfith its velvet- 

 Uke wings of intense black 

 and rich green, has only 

 been received from Amboyna.
