LIFE-HISTORY OF ANOSIA PLEXIPPUS. 379 



The ground colour is a pearly-grey with a very slight 

 yellowish tinge in shadows. The second subdivisional wrinkle 

 is light brown, forming a band which gives a ringed appearance 

 to the larva. The surface is covered with minute black granu- 

 lations ; the legs are black, and claspers olive-black and pearly- 

 ochreous. 



Before first moult it measures ^^q in. long; the ground colour 

 is pearly-ochreous-white with a black stripe encircling each 

 segment. The first larva, which hatched 5.30 a.m., August 

 12th, moulted first time 6 p.m., August 16th, being four and a 

 half days in the first stage. 



Before second moult it measures /g in. long. The head is 

 now similar in coloration to the subsequent stages, being pale 

 yellow, striped with black ; the posterior subdivision of each 

 segment is lemon-yellow, each segment is encircled with a black 

 band ; the subdorsal knobs are developed into short tubercles. 



One which moulted the first time on the evening of June 8th, 

 1910, fed at very frequent intervals during both day and night 

 in its second stage, and fixed for its second moult on the morning 

 of June 10th, and moulted the following morning, remaining 

 only two and a half days in the second stage. 



The one which moulted first time, August 16th, 1911, moulted 

 second time on August 19th. Another which hatched 6 a.m., 

 August 12th, moulted first time, August 15th, and the second 

 time on the 18th. 



Before third moult it measured ^ in. long ; all the markings 

 of the subsequent stages are now visible. 



The larva which moulted second time, June 11th, 1911, fixed 

 itself for the third moult morning, June 13th, and moulted the 

 third time early morning of the 14th. 



After third moult it is f in. long. In all respects it is similar 

 in both colouring and pattern to the fully grown larva. The 

 anterior tentacles now measure } in. long. 



Shortly before fourth moult it measures from | in. to 1 in. 

 long ; the anterior tentacles now attain ^ in. long. All the 

 colours are clear and defined. 



Fourth moult, midnight, June 18th. Its first meal after 

 moulting consisted of its cast skin. 



After fourth and last moult fully grown, the larva measures 

 2^ in. long, the body is of uniform thickness, excepting the 

 rather tapering first and last segments. The head is yellow, 

 with three transverse black hoop-like bands, the central one 

 above the mouth is united below, forming a black Q, the surface 

 is sprinkled with minute fine black hairs. On each side of the 

 second segment is a long subdorsal fleshy velvety-black tentacle, 

 very slender and cylindrical, densely clothed with extremely mi- 

 nute points, and sparsely sprinkled with fine black hairs. These 

 organs project over the head, are slightly upturned and widely
