Mr. W. F. Kirby on a 



LI. — On a Collection of Odonata (D r ago nflies) from 

 Panama. By W. F. Kirby. 



[Plate XV.] 



In the course of last year I received a consignment of Odonata 

 for the Natural-History Museum from Mr. Charles H. Dolby- 

 Tyler. They were all taken by himself between April 1 and 

 May 15, 1898, at La Chorrera, about 20 miles north of Panama. 

 Accompanying them were short descriptions, " taken in most 

 cases from two or three specimens while the insect was alive, 

 and jotted down in my note-book Among the un- 

 numbered duplicates you will find two, or possibly three, 

 species not included in the series." 



The numbers on the specimens run from 1 to 20 ; but as 

 the sexes of several species bore different numbers, the total 

 number of species (including those not numbered) is not more 

 than 21. Several of these are of considerable interest and 

 some appear to be new ; and hence I have thought it would be 

 useful to give a list of the whole, printing Mr. Dolby-Tyler's 

 descriptions of the living insects exactly as I received them, 

 between inverted commas, and adding any remarks of my 

 own which seemed to be necessary. As usual, many more 

 males than females were collected. 



The list of species is as follows : —
