divergent at the tips ; while feeding they are kept in constant 

 motion, generally jerked quickly to and fro. On the eleventh 

 segment is a much shorter pair of similar structure. The ground 

 colour of the body is pale lemon-yellow and white, the white 

 forms a broad median band round each segment ; the segments 

 are striped and banded with velvety-steel- black, the stripes, two 

 in number on each segment from the fourth to tenth inclusive, 

 reach over the dorsal surface down to the spiracle, and separate 

 the white from the yellow. One anterior, and one at the pos- 

 terior third, between this and the segmental division is a short 

 transverse dorsal streak ; midway between the two larger stripes 

 is a band of the same velvety texture completely encircling the 

 body and enclosing the spiracle, which is also black, above the 

 clasper is a black oblique mark. The black bands extend over 

 the frontal half of each leg and clasper, the posterior half white, 

 the feet of both legs and claspers are shining black. The seg- 

 mental divisions are broadly black ventrally, tapering to a thin 

 streak dorsally. The entire surface is sparsely sprinkled with 

 extremely small clubbed bristles with dark bulbous bases. These 

 are only visible under microscopic power. 



The larva appears of very docile temperament, if I may use 

 the term, as they take but little notice of being disturbed, and if 

 touched while feeding they merely stop for a few seconds and 

 then continue, and are quite content to feed in any attitude they 

 may be placed in ; their only object is to be almost continually 

 feeding, consequently they rapidly grow. 



The larva described which moulted midnight, June 18th, 

 became fully grown and stopped feeding on the evening of June 

 23rd ; it spun up, attaching itself by its anal claspers to a pad of 

 silk spun on the leaf stalk, on the following morning, and pupated 

 the next morning, June 25th. 



Another fully grown larva ceased feeding on June 8th ; after 

 roaming about for six hours it spun a silk pad on the gauze 

 covering, and suspended itself and pupated the following evening, 

 June 9th. The next morning the colouring of the pupa had 

 matured. The first two which hatched, August 12th, 1911, became 

 fully grown and stopped feeding on the afternoon of August 26th, 

 and roamed about for many hours. They both suspended 

 themselves the following afternoon and pupated the next after- 

 noon, August 28th, having remained in the larval state sixteen 

 days. 



The pupa measures 1 in. long, including the cremaster, and 

 is ^ in. wide across the middle of the abdomen ; it is proportion- 

 ately stout for its length, rounded and remarkably smooth, having 

 no angles or projections. The abdomen is conical and terminates 

 in a stalk-like cremastral process, the whole form producing a 

 beautiful pendant object, especially when viewed either dorsally 

 or ventrally, and from its smoothness, colouring, and general
