In the next year of the ' Verhandlungen ' (vol. ix. 1859, 

 pp. 206, 207) Hagen published the followiug supplementary 

 list :— 



1"Calopteryx (Vestalis) amcena,^ayeM. 



*Lestes orientalis, Hagen. 



*Disparoneura maculata, Nietn. 

 (D. ter\a,x,Hagen=Agv[on t., above.) 

 (D.hilaris,Zrfl$'m=A. hilare, above.) 



*D. centralis, Hagen. 

 (Grynacantha subinterrupta, Bamh., 

 additional note.) 



tLibellula stylata, Bamh. 



tL. flavescens, Fabr. 



tL. rufa, Bamh. 



Vestalis apicalis, Selys. 

 Lestes orientalis, Selys. 

 Platysticta maculata, Selys. 



Disparoneura centralis, Selys. 



Tranea stylata, Bamh. 

 Pantala flavescens, F. 

 Erythemis rufo, Bamh. 



This raises the number to tliirty-five species.

 ditions, for Jj. marcia, 'Dva. = variegata, L. ; and L. flavescens 

 and viridula are synonyms of one species (which had already been 

 included in Hagen's second list). Motschulsky (Bull. Soc. Nat. 

 Moscou, xxxvi. no. iii. p. 8, 1863) merely quotes "Walker's list, 

 with the accidental omission of Libellula aurora, Burm. 



Since this time some of Hagen's MS. species have been de- 

 scribed by Baron de Selys-Longchamps, and several other 

 species have been recorded or described as new from Ceylon by 

 De Selys, Hagen, Brauer, Karsch, and myself. But the only 

 special paper on the subject is one of my own, " On some
