The Museum collection contains only a single damaged male 

 of this species. It is fairly common in the Malay Peninsula. The 

 ]Museum specimen is from Puepoli, Burma. 



19. Pseudophaea brunnea (Sel3^s).

This is a large form closely allied to the smaller P. ochracea. 

 A very similar large species or subspecies from Lombok has been 

 named Euphaea lava by Foerster, but I am not able to find the 

 reference, 



P. hrunnea is not in the Museum collection. 



Genus Philoganga, Kirby. 

 = Anisoneura , Selys (nom. praeocc). 

 20. Philoganga montana (Selys).

The position of this remarkable genus in the subfamily Bpal- 

 laginae is doubtful. Other genera included by Selys in the legion 

 Amphipteryx, which do not concern us here, though not neces- 

 sarily allied to A mphipteryx will also probably require to be removed 

 from the subfamily. 



Genus Rhinocypha, Ramb. 



This is the most characteristic genus of dragonflies of tropical 

 Asia, striking both in respect of the great beauty and briUiance of 

 its members and of the abundance of species. In the whole 

 Oriental Region the island of Ceylon and the great valleys of N. 

 India alone are lacking in representatives. 



The arrangement I have adopted in the following list differs 

 a little from that hitherto used, especially in the grouping together 

 of R. unimaculata and R. trimaculata. I believe these species to 

 form a natural group within the genus. I hope that students who 

 have the good fortune to be able to study these fascinating and 

 exquisite insects in the field will soon furnish us with information 

 as to their life-history and habits.
