them, it lives on the leaves of the llijpfrinim bacelfirum, known in Surinam under the name of 

 Ringwurrakruid, and on various sjiccies of Cagsin ; it is met with at various times of the year, it grows 

 rapidly and does not change colour until about to undergo its mctaiuorphnsis. then it assumes a shining 

 yellowish tint, the chrysalides are either red or green." 



The most quaint descri])tion of C. Sennce, in all its stages is to bo found in SK.an's History of 

 Jamaica (p. 212, 172r>) as follows — 



The Common Yellow Caterpillar. 



" Its bigness is as that of a goose-quill, it is about an inch long, of a yellowisli colour, haviiij.' 

 here and there black spots on it, after it attains it,s duo growth it becomes the — 

 AuRKLiA Triangularis Purpurea, Lineis Lutkis Ndtatis, 

 The Common Triaxqclar Aurelia. 



This is almost triangular, about half-an-inch long, and one-fourth part of an inch broad at 

 broadest, having here and there some angles and eminences, and is sharp at both ends ; it is of a 

 purple colour with some j-ellow streaks. When the worm or catei pillar has fed itself full, it creeps U- 

 a place free from wind, and there fa-stens one end to the under part of a stone, twig, &c., and the other 

 end hangs in a string like that of a spider's web. where it takes this figure and comes out — 

 The Common Yellow Butterfly. 



Tliis was about an inch long from the head to the tail, about twice as much from wing to wing 

 .'xtended ; it had six feet, three of each side, it had two brown antennve, three quarters of an inch long 

 went out of its brown head, and two large brown globular eyes. It had hanging out of its moutli a 

 long spiral twirling Proboscis, of a brown colour ; the body was covered over with a long yellow down 

 and the wngs with a shorter, there were in the middle part of each of the four wings, two silver spots 

 or eyes, inclosed in a brown circle, or Iris, besides several other brown spots or lines, here and there, 

 especially on the margin of the wings on the upper sides. On that pair of wings nearest to the head, 

 or the upper ]>air, were by the outside, two brown spots as big as a large pin's head. 



The Krncn of this butterfly above described, Xo. 1, feeds on what they call here Wild Indign. 

 They are the most common of all butterflies." 



The figures accompauying the above description are tliose iiuoted by Linna?us for his C. Seniue.
