REPORT ON THE DRAGON FLIES. II 
THE LEGIONS PLATYCNEMIS AND PROTONEURA 
By F. F. LAIDLAW, M.A. 
WITH NOTES ON SOME MALAYAN SPECIES 
By Dr. F. FORSTER 
T HANKS to Dr. Forster’s kindness I am able to add to my account of 
these species some very interesting notes written by him, as well as 
descriptions of new species and subspecies in his collection. 
Of these notes I have translated some (printed here between square 
brackets). These deal with species already described ; whilst his descriptions 
of new species or subspecies, as well as a review of certain species belonging 
to the genus Disparoneura , I have left unaltered in German. 
The two accounts add considerably to what is known of the distribution 
of these forms in the peninsula, whilst Mr. An nan dale’s field-notes are 
especially welcome because of the accurate dates given, and also because they 
supply information, to some extent, as to the colours of the living animal. 
I hope to deal with some points in connection with the geographical 
distribution of these species later when I am able to deal with the Odonate 
fauna as a whole. But I wish now to call attention to a recent paper by M. 
Martin on the Odonata of Indo-China [: 04], which adds very largely to our 
knowledge of the distribution of the Odonates of the Oriental region, and 
shows that Indo-China is surprisingly rich, especially in members of the 
Calopteryginae. Thus he records no fewer than three species of Dysphaea from 
Tonkin, as well as a large new species of Echo, and also Tetraneura argyroides. 
The genus Micromerus appears to be absent, but Libellago asiatica is noted as 
having been taken in Tonkin. Williamson’s paper also (see below) gives 
much interesting information. 
The following is a list of recent papers on the Odonata of the Oriental 
region, some of which are referred to in the following papers : —
