lighter than the gi-uuad colour. The spiracles were still light in 

 colour, with black rims, and on either side of each was a black tubercle, 

 and also one below it, all furnished with a black bristle. The anal 

 flap was dotted with dark tubercles, and possessed six stiff black set^e, 

 three on each side, all directed backwards. The ventral surface was 

 dull in colour, and blotched with olive-grey. The legs were ringed 

 with dark lines, and dotted with minute warts, as also were the 

 claspers. In colour, these were almost of the same tint as the head. 



On June 4th, the larva was about j\-'ni. in length. Seen with the 

 unassisted eye it was shining in appearance, with a pale yellow-brown 

 head, and tinged with the same tint posteriorly. The dorsal surface 

 was of a pale olive-green in colour, and the spiracular portion of a 

 pale yellowish -grey. The abdominal region was of the same tint as 

 the dorsal, and all of the legs and claspers, were marked with heavy 

 skin-folding at their junction with the body. Under the lens the head 

 was still of a pale yellow-brown, with a finely reticulated surface, 

 bearing white seta?, and on each cheek the semicircular arrangement 

 of black warts still remained with a lower one as their axis. The pro- 

 thoracic segment was sharply folded across the crown of the head, and 

 the colour of the head suffused into it ; as also was the same colour in 

 the anal segment suffused into the twelfth. The dorsal surface was 

 blackish-green, subdivided by four blotched, irregular, whitish lines. 

 These started sharply on the prothoracic segment, from its anterior 

 edge above the head and travelled in a broken manner for the whole 

 length of the larva. The four black warts on the dorsal face of each 

 segment were still in evidence, but were now wanting in their light 

 circumscription. The dorsal colour finished rather sharply on the 

 summit of the anal segment in a point, amongst heavy skin -foldings. 

 There was an irregular, light, lateral line on the edge of the spiracular 

 portion, and a similar one on the line of the spiracles precisely. All of 

 these lines were extremely difficult to locate, owing to their irregular 

 and broken course, and the very glossy surface of the larva's skin. 

 The spiracles were still light in tint, surrounded with black rings, and 

 were set amongst the heavily corrugated skin-folds of the spiracular 

 line, which was freely dotted with minute black warts. The legs and 

 claspers were of the light colour of the head, and blotched and 

 sprinkled with black warts. The entire larva was well provided with 

 short, black hairs, which sprang from the warts ; while the anal seg- 

 ment still possessed the six stiff, dark, sette, pointing backwards. On 

 June 9th, the larva was §in. long, and had undergone a radical change 

 in construction, being much altered in colour. Its appearance, seen 

 with the naked eye, was sage-green, with a dark brown head, anal 

 segment, and spiracular region. Under the lens it presented a most 

 beautiful study. The head was of a light chestnut colour, blotched 

 with black, in a manner which forcibly recalled the markings upon the 

 skin of the jaguar. The cheeks were free from these markings, but 

 still carried the four dark warts in a radius upon a fifth, lower down. 

 These black warts were now set in a white ring, which was sharply 

 defined against a dark chestnut edge around them ; which was, in its 

 turn, suffused into the general coloration of the head. The mouth 

 was cold blue-gray, with a projection on either side, set forward, and 

 each tipped with a bristle. The head was porrected in carriage, and 

 possessed several white sette, also set forwards. The dorsal surface, sage-
