journals of passing naturalists, the enumeration and description 

 of the Hongkong insects have been entirely neglected. Despite 

 this fact, a rich field there awaits the collector and the scientist, 

 as the beetles, butterflies and moths are often of exceptional size 

 and great beauty. An Attacus (male) in the writer's possession 

 measures no less than eleven and one-half inches across the wings. 

 Of beetles alone — according to Frauenfeld — Mr. John Bowring 

 (son of Governor Bowring, of Hongkong), collected more than 

 twelve hundred species, many of which were new to science. 



In compiling the following list, the entomology of various other 

 localities throughout the province of Kwangtung has been taken 

 into special consideration. Notably that of the other islands in 

 the Ladrones group of the Lo-fan Mountains — where some time 

 was spent in collecting — and of Macao. In the latter port the 

 writer passed several months, and succeeded in making valuable 

 collections, thanks to the courtesy of Governor da Graca, who 

 did everything in his power to facilitate the work. A complete 

 catalogue and description of the collections then made have since 

 been embodied in a work entitled " Fauna Macanensis," recently 

 forwarded to the Portuguese Government. It is somewhat diffi- 

 cult to keep the entomology of Hongkong entirely distinct from 

 that of adjacent islands and mainland. As has already been stated, 

 the hills opposite Hongkong practically introduce the insect fauna 

 of the entire Kwangtung Province. At times, months or even 

 years may pass before the reappearance of a certain species ; and 

 then a favorable wind may waft it unexpectedly into the flower- 

 gardens of Victoria, there, mayhap, to completely puzzle the 

 brains of some ardent entomologist. In the following list, how- 

 ever, all doubtful species have been so far as possible excluded, 

 and only such admitted as have been identified by scientists of 

 acknowledged ability.
