Part XIV. 
Family— AESCHNIDA: (Cont.). 
Since the Ms. of Part XII went to the press, Mr. C. F. Beeson of the Forest 
Research Institute, Dehi-a Dun, has sent me several new species belonging to 
the family Aeschnidce and as these have not yet been described, I take this op- 
portunity of including them in our list.
