Majoe F. C. Fraser, I.M.S. 

 {With 4: Text-figures.) 

 (Continued from page 269 of Volume XXVII.) 

 Part IX. 



In this part the large subfamily Libellulinse is completed. The genus Nanno- 

 phya, which was omitted in error, is now given, together with the descriptions 

 of two new species of Lyriothemis which have been published since this work 

 was begun. 



I take the opportunity also of correcting a number of errors which have crept 

 into the text, and amongst these must especially be mentioned that of the mal- 

 position of the figures of Lyriothemis cleis, Potomarcha obscura and Lathrecista 

 asiatica. 



Genus — Lyriothebhs. 



78. Lyriothemis tHcolor, Ris, Cat. Coll. Selys, pp. 1063-1065. (1916). 

 Lyriothemis cleis, Ris, Cat. Coll. Selys, pp. 108, 111 (1909).

Head : labium bright yellow, middle lobe blackish ; labrum, face and foiehead 

 bright yellow ; a metallic, bluish green, nearly quadrate spot on the centre of 

 upper surface of forehead ; vesicle metallic, bluish green ; occiput bright yellow. 



Pro thorax black. 



Thorax deep mahogany blackish brown with bright yeUow markings as 

 follows : — two rather narrow, long, oval, antehumeral spots on the front about 

 midway between the median dorsal carina and humeral suture, the space between 

 them much darker brown than the rest of the thorax, spots on the tergum and 

 two very broad, lateral bands, the posterior of which covers the whole of the 

 metepimeron save for a narrow border behind and below : the legs ringed with 

 yellow at their bases, the legs themselves entirely black.
