1 76 THE MEMORABLE. 



in the manner of gnats, or as the ghost-moth in England 

 plays at the side of a wood. After watching them awhile, 

 I noticed that some of them were resting with closed 

 wings at the extremities of one or two depending vines. 

 One after another fluttered from the group of dancers to 

 the reposing squadron, and alighted close to the others, so 

 that, at length, when only about two or three of the fliers

 and one or two flew up again. As there were no leaves

 butterflies, so crowded together, their long erect wings 

 pointing in difi'erent directions, was not a little curious. 

 I was told by persons residing near, that every evening 

 they thus assembled, and that I had not seen a third part 

 of the numbers often collected in that spot.

 rich velvet black and emerald green, arranged in transverse 

 bands, with a broad disk of ruddy gold, the whole spark-

 besides, an insect of unusual interest to the philosophic 

 entomologist, because it is one of those transitional forms
