Show 1891.] ON NEUROPTERA-ODONATA (DRAGONFL1ES). 203 3. On some Neuroptera Odonata (Dragonflies) collected hy Mr. E. E. Green in Ceylon. By W . F. KJRBY, F.L.S., F.E.S., Assistant in Zoological Department, British Museum (Natural History), S. Kensington. [Received March 17, 1891.] (Plate XX.) Among the insects from Ceylon which Mr. E. E. Green has lately presented to the British Museum are a few Dragonflies, representing 16 species, 3 of which appear to be new, while one or two of the others have not previously been recorded from the island. As they are nearly all carefully marked with dates and localities, I think it will be useful to enumerate them, though the small number of species represented renders it impossible to attempt any generalizations.
