dragon-fly, and since its haunts are by the -water-side, tliis may be of service to tlie 

 insect. Its fliglit, however, hardly bears out this resemblance, consisting of a kind 

 of dancing motion — a series of mid-air jumps, so to speak — very diiTerent to the 

 direct swift flight or the steady hovering motion of the Lihellulidce. Still, the rapid 

 vibration of its transparent wings strongly reminded me of the dragon-fly, and it is 

 possible that it sometimes hovers in its flight, after the manner of the latter, though 

 I did not see it do so" (Distant, Rhop. Malay, p. 365). Mr. H. 0. Forbes has 

 publisbed similar observations, made in Sumatra : " By the margin of a small 

 stream I caught Lep. virescens, which derives protection from mimicking the habits 

 and appearance of a dragon-fly, in a crowd of which it is often to be found. In 

 form it reminded me of the European genus Ncmoptera. It flits over the top of the 

 water, fluttering its tails, jerking up and down just as dragon-flies do when flicking 

 the water with the tip of their abdomen. When it settles on the ground it is 

 difficult to see, as it vibrates in constant motion its tails and wings, so that a mere 

 haze, as it were, exists where it rests." (Nat. Wand. I]ast. Archipel. p. 139.) 

 Dr. L. Martin says : " Both species of Leptocircus, found in Sumatra, are fond of 

 running water, and fly very low over open grassy places on river banks ; they often 

 settle on wet sand, but never on the grass. When flying they make constantly a 

 strange vibrating; motion with the hindwing:s, which adds to their strong- resemblance 

 to dragon-flies." (J. As. Soc, Bengal, 1895, 529.)
