p. 56 (Kedah and Junk Sejdon). 



We have been able to compare our Kedah and Junk Seylon 

 series with examples of D. longicatvdata from Dharmsala in the 

 Punjaub and, as suggested elsewhere, find that thej^ are a race of 

 that species : they are distinguished by smaller size (shorter tail and 

 wings) and slightly paler, greyer abdomens. D. sfevensi Baker 

 (Nepal to the Bhramaputra river) appears to be another subspecies.

If D. I. nigrescens is really .separable from D. I. intermedius 

 (which we doubt) it is so, apparently, only because of slightly larger 

 size.
