PREFACE. 



of the eastern parts of India. These are, therefore, doubtless the inhabitants 

 of the immediate neighbourhood of Canton, which lies in the same degree of 

 latitude with Bengal. A valuable addition has indeed been made to our 

 knowledge of the entomological productions of Mongolia, and some of the 

 adjacent northern portions of China, by M. Faldermann's publication* of the 

 Coleopterous insects brought from those regions by M. Bungius ; from which 

 it would appear that the entomological productions of such portions of China 

 as lie between 40" and 50° of north latitude are quite unlike those of the 

 neighbourhood of Canton lying beneath the tropic of Cancer, bearing, indeed, 

 a far greater resemblance to those of central Russia. It is to be hoped 

 that M. Faldermann will speedily publish the descriptions of the species 

 belonging to the other orders of insects lirought from this interesting portion 

 of the globe.
