Firstly, in dealing with the sexual characters of Tetrathemis, 

 I was not acquainted with a paper of Dr. Foerster's published 

 in the ' Termeszetrajki Fuzetek' (1900, pp. 81-108), where, in 

 describing two new species of this genus from New Guinea, he 

 calls attention to the peculiar differences between the armature 

 of the femurs of the two sexes. Secondly, he has pointed out in 

 a letter that the forms which I identified as Gynacantha roseti- 

 bergi Brauer probably do not belong to that species, which does 

 not occur west of Banda. My specimens are perhaps referable 

 to G. hasiguttata, but I have not had the opportunity of re- 

 examining them. 



Lastly, in my description of Gomphus coiisohrinus'^ (P. Z. S. 

 1902, vol. i. p. 80), "Type A of Selys" should read "Type B of 

 Selys," whilst Echo tricolor Kriiger, on page 85, should be altered 

 to E. iricolor Kriiger.

Ooncerning this species, I find the following notes in my diary : — 

 Aug. 20th (1899) : " I found to-day large numbers of a species of 

 Dragonfly over a pond ; I caught several pairs." 



Aug. 28th (1899): "I noticed that the species which I had 

 seen so abundantly near the pond had disappeared almost entirely. 

 I have only found it in this one spot," 



Legion PODAGRION.

1 Mv. Calvert has pointed out to me, since this paper was read, that this name is 

 pre-occupied by Gomphus cousobrinus Walsh = G. externa Selys (see Kirby, Cat. 

 Odonata, p. 66). Accordingly, I propose to alter the name to G. kelantanensis.
