For species of other groups I quote, where available, Kirby's' 

 'Synonymic Catalogue of Neuroj^tera Odonata' (1890) as " Kirby, 

 Cat. Odonata," and, in addition, i-eferences to later papers. Of 

 these, Fasc. xvii. of the ' Catalogue of Collections du Baron Edm. 

 de Selys-Longchamps,' dealing with the Cordulinse, by Martin, 

 is referred to as " Martin, Cat. Coll. Selys, Cordul." ; whilst Fasc. 

 xviii.-xx. of the same Catalogue, dealing with the ^schninie, 

 are referred to as " Martin, Cat. Coll. Selys, ^schn." 



1 have in certain cases given measurements of the specimens 

 noted, in each case of the abdomen "abd." and hinder-wing " h. w." 

 In the case of the male, after the measurement, of the abdomen, 

 the sign + followed by another measurement refers to the length 

 of the anal appendages. 



Where the venation of the wings is discussed, I have used the 

 revised nomenclature proposed by Tillyard in his book, 'The 

 Biology of Dragonflies.' 



An asterisk placed before the name of a species signifies that 

 I have not seen a specimen of that species from Borneo. 



Parentheses around the names of authors placed after specific 

 names in this paper are used in accordance with Article 23 of 

 the International Rules of Nomenclature (Proc. 7th Int. Cons. 

 Boston, 1907, p. 44 (1912)).
