CEL^NA HAWORTHII. 109 



series on the back, gradually decreasing in size from 

 the fourth to the eleventh segment, were more con- 

 spicuous on the thoracic segments, for there they 

 were transversely oval in form, as they also were on 

 the twelfth, and on the front subdivision of the thir- 

 teenth segment, and considerably enlarged on these 

 last; most of the spots along the sides were round, a 

 small one a little above and a large one a little behind 

 each black spiracle, while lower down towards the 

 belly were two more in a line with each other parallel 

 to the line of spiracles ; those on the sides of the 

 third and fourth segments were larger, and somewhat 

 of a drop shape, the largest being behind ; below them 

 were three others, smaller, forming a triangle on each 

 of these segments ; the side spots were also enlarged 

 on the twelfth and thirteenth segments ; the hind ridge 

 of the anal plate and the tips of the ventral prolegs 

 were dark ochreous-brown. 



The above description exactly suited to the three 

 healthy larvse, and also the sickly one as far as details 

 went, but the colour of the skin of that larva was pale 

 greyish. 



The pupa was half an inch in length, moderately 

 thick in proportion, widest across the thorax, and 

 thence diminishing a little towards the blunt and 

 rounded anal extremity, which was furnished with two 

 sharp bristle-like spikes meeting near their points ; the 

 wing-cases were well defined, but not very projecting ; 

 its colour at first was a light reddish-brown, which 

 changed gradually afterwards to darker brown, the 

 abdominal divisions a little paler than the rest and 

 with little gloss, the other parts being highly polished.
