‘The list given below adds several species to the known Bornean 
fauna and includes a high percentage of undescribed forms. It 
will be noticed that probably all the Agrioninae are new to science, 
a fact which enables one to realize how imperfect our knowledge 
of the dragonflies of the old world tropics still remains. 
Consequent on this it follows that the systematic arrangement 
of the Agrionine genera in particular is highly unsatisfactory, 
which is to be the more regretted in that these insects are no doubt 
capable of affording valuable clues for the elucidation of many 
problems of distribution. Carefully made collections from other 
parts of Borneo, from the Celebes, and Philippine Islands, especially 
from the mountains, no less than from other parts of the Malay 
Archipelago are much to be desired in order to amplify the re- 
searches of de Selys, Ris, Kruger, Martin, and others, who have 
devoted attention to the distribution of the Austro-Malayan Odo- 
nate fauna. I wish to offer my sincere thanks to Mr. Moulton for 
the time and trouble he has spent in making this collection and in 
putting it and much other valuable material in my hands for 
examination. I take the opportunity here also of recording my 
indebtedness to Dr. Ris and to M. Martin for the generous assis- 
tance they have so cordially extended to me at all times. 
Interature. In addition to the volumes of the Catalogue of 
the “ Collections zoologiques du Baron Edm. de Selys Longchamps ” 
dealing with the Odonata, which have so far appeared, which Dr. 
Ris and M. Martin have compiled, the following papers of recent 
date have been consulted. For earlier papers dealing with the 
odonate fauna of the Malayan region reference should be made 
to the very full bibliography given by Kriiger in his studies on the 
Odonata of Sumatra.
