NOTE ON A COLLECTION OF ODONAJA FROM SOUTH ANNAM. 
BY Major F. C. Fraser, I. M. S. 
( With one text-figure ). 
INTRODUCTION 
The collection, which contains 119 specimens and has repre- 
sentatives of 34 species or about one fourth of the Odonate fauna 
of South Annam, is fairly representative of that part of Indo-China, 
although the smaller forms of Zygoptera are not in evidence. There 
appears to be one new species in the list which is detailed below, and 
I am a little in doubt with regard to an Anotogaster of which a 
female is the sole representative of its genus in the collection, and a 
very teneral male of Megalestes which was so compressed in the paper 
packet that it was impossible to make out the formation of the anal 
appendages. 
[ The small collection of Dragonflies which Major Fraser has 
kindly determined for us was made by Dr. Malcolm Smith and 
myself during a visit to South Annam in the spring of 1918. 
Our camp at Daban was pitched near the Kronfa river 
where it makes exit from the mountains of Langbian, and when we 
went to bathe in its clear waters running among rocks and boulders 
it was our custom to take a net with us on account of the beantiful 
insects that flitted over the river; such were Nos. 24, 25, 27, 28, 
29, 30. 
Most of the other species from Daban were taken along a 
path running between the river and the forest through a patch of 
coarse grass-!and interspersed with saplings and bushes; these were 
Nos. 1, 3, 4, 5, 6, 8—18, 20—22, 32—34. The species of Newrothe- 
mis were very common and mixed together in this place, perching 
on twigs and grass stems. 
The few examples from Dran (Nos. 7, 15, 23, 26) were taken 
in grass country near water. Dalat, whence came ‘Nos. 2, 9, 19 and 
26, is grass country covered with pine forest. 
The camp on Langbian Peaks was set on a grassy slope at the 
edge of mixed forest (No. 31).
