hovering over pools and rivulets in the sunshine." Mr. S. B. J. Skertchly (Ann. 

 N. H. 1889, 217) says, "I have only seen it, in N. Borneo, on streams and rivers in 

 rocky places well open to sunshine. It is an exceedingly swift flyer, darting with 

 rapidly vibrating wings from point to point, dashing backwards and forwards over a 

 particular patcli of sand like a dragon-fly, and making considerable journeys in the 

 day. Like many other butterflies, it is methodical, frequenting the same places at 

 the same hour ; so that when once seen, I could always find it again. It is an early 

 riser, and may be caught drinking before nine o'clock. It delights in hot sunshine, 

 and is comparatively sluggish on dull days. When drinking it has a most 

 remarkable habit of ejecting the water from behind. Pushing its proboscis into the 

 wet sand, it takes long steady drinks, and pumps the water out astern in I'hythmic 

 squirts, foriBing quite a little stream. It can project the water full three inches. 

 At such times it can be approached closely if no sudden movement is made. It does 

 not always pump, and I have often watched for it in vain." Mr. J. J. AYalker, E.N. 

 (Tr. Ent. Soc. Loud. 1895, 472) writing of the white-bandtd Leptocircus found in 

 Hongkong, remarks that it is " met with in February, March, and April. It is 

 hardly possible to imagine a more daiutj' and elegant little creature, as it feeds at the 

 white blossoms of its favourite shrub, Buddlxa asiatica, probing flower after flower 

 of the racemes with its proboscis, with the long tails of the hindwings elevated and 

 quivering, and vibrating its wings all the time without actually settling, like its 

 larger relatives, the Papilios. When alarmed it booms off rapidly, with a flight 

 resembling that of the larger Hesperiidte. I have never seen it hovering over 

 running water in tlie manner described by Mr. 11. O. Forbes, although there is a fine 

 stream in the gardens where they were taken."
