A NOTE ON SOME DRAGONFLIES FROM AMBOINA. 263 
from Amboina, belonging to the University Museum of Zoology, 
Cambridge. These Dragonflies were obtained by Mr. Frederick 
Muir during his visit to that island in the year 1908, and as 
soon as caught they were immersed for a time in hot alcohol 
with the object of preserving their natural colours. To a con- 
siderable extent this object has been achieved, although the 
colours have obviously undergone a certain amount of bleaching. 
According toa recent faunistic catalogue (Ris, ‘ Nova Guinea,’ 
xill, Zool. (2), pp. 117-128, 1915), Pseudagrion microcephalum, 
Ramb., has not been known previously to occur in the Moluccas 
at all, while Xiphiagrion cyanomelas, Selys, T'einobasis superba, 
Hagen-Selys, and J'rithemis festiva, Ramb., are now specially 
recorded for Amboina for the first time. 
Subjoined is a list of the species represented in the collection : 
CALOPTERYGIDE. 
Rhinocypha terminata, Selys,4 3,12. 
AGRIONIDA. 
Caconeura moluccensis, Selys, 7 3,29. 
Agriocnemis fenmina, Brauer, 3 3, 1 green 2,1 orange °. 
This record has been published by Dr. Ris (‘‘Suppl. Entom.” 
Wo;¥, p: 23,1916). 
Xiphiagrion cyanomelas, Selys, 2°. 
Pseudagrion coriaceum, Selys, a series of males and females. 
Pseudagrion inicrocephalum, Ramb., 2 ¢,2 2. This species 
ranges from Bombay (the type locality) to Eastern Australia, 
and its occurrence in Amboina was not unexpected. I have 
compared a male and female from Mr. Muir’s collection (the 
latter, however, rather discoloured) with Indian material of both 
sexes from Goa and Lake Chilka, kindly lent to me by Dr. F. F. 
Laidlaw. A close general agreement was found to exist, except 
in the matter of the superior anal appendages of the male, which 
are, of course, considerably broader in the Amboina specimen 
than in the examples from India. The various forms assumed 
by those appendages in Ps. microcephalum have been fully dis- 
cussed by Dr. Ris (loc. cit., pp. 40-42, 1916), but the appendages 
of the specimen before me do not strictly correspond with any of 
the figures given by him. 
Teinobasis superba, Hagen-Selys, 1 2. For this identification 
I am indebted to the kindness of M. René Martin. 
LIBELLULID®. 
Nannophlebia lorquini, Selys,2 ¢,3 2. 
Nannophya pygmea, Ramb., 1 2. 
Neurothemis stigmatizans manadensis, Boisd. 2 2. 
Trithemis festiva, Ramb., 1 3.
