others. Most of the Asiatic genera occur in the Malayan Archi- 

 pelago; there are, however, others yet undescribed, which so far 

 appear to be Asiatic only. 



There are twenty-eight genera in the collection, and one hundred 

 and sixty-four species. In the following table of the genera I 

 have intentionally given prominence to the most obvious charac- 

 ters, rather than the most important.
