though not confined to it ; and, in like manner, Liaeos, Prosopis, 

 JVomia, and Crocisa have a greater development in the Australian 

 region. 



The great inequality of our knowledge of the different islands 

 prevents me from going into more detail as to the facts of their 

 distribution. It must not be supposed, when we see 7 or 10 

 given as the total of the Hymenoptera from one island, and 216 

 or 290 from another, that either of these numbers gives any 

 approximation to the sum total of the species inhabiting that 

 island. They merely show what one collector was able to do in 

 each under very different circumstances ; and they indicate the 

 points at which future collectors may work with most advantage. 

 The comparatively small number of species yet known from the 

 countries which I have grouped under the term Chinese Asia, 

 from Birmah to China inclusive, and the still more scanty list 

 from the Philippines, show how much there is yet to be done in 

 those countries, even to bring them up to the standard of our 

 still very imperfect knowledge of the Malay archipelago. I 

 would also point out Sumatra, Java, and Timor as islands that 

 would yet well repay an assiduous and persevering entomologist, 

 and which can be visited with much less privation and risk than 

 would be encountered in penetrating to New Guinea and the 

 unknown islands east of it. I would observe, however, that 

 though the individual islands are very unequally known, yet the 

 total number of species obtained from the chief groups of islands, 

 viz. Indo-Malay islands 417, Celebes group 295, Moluccan 

 group 280, Papuan islands 296, indicate a tolerably equal amount 

 of research over the various portions of the archipelago, and 

 render the few results I have deduced from them worthy of some 

 confidence.
