Herr Bock recently forwarded two collections of Odonata from 

 the Mountains of Paio in Sumatra. They were not rich in species, 

 but the number of individuals was yery considerable. As so little is 

 yet known of the Odonate-fauna of this island, the following notes 

 on the few Galopterygina may prove useful. 



Neurobasis chinensis, L. — Several males (but no ? ). According 

 to De Selys (4^^^ Additions, p. 14) females from Sumatra, seen by him, 

 belong to the typical chinensis and not to the racejlorida, Hagen, as

 posterior wings. In the males seen by me the nodal sector originates 

 from the nodus, as in typical chinensis. 



Yestalis lugens (Albarda), De Selys (4"^^^ Additions, p. 15, 

 1879). — Probably more than 100 examples (mostly ^). Those ^ in 

 which the wings have coppery-brown reflections (as noticed in the
