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 

 belono-ino- to the other orders of insects brought from this interesting portion 

 of the globe.
