5 and 14 have a similar lateral tubercle, that on segment 14 being a simple 

 knob, that on segment 5 short, those on the other three segments being 

 longer — the one on segment 4 is slightly longer than the other two. 

 Besides these tubercles there is a spiracular row, on segments 2 to 14 of 

 short ones about half as long as the lateral ones on segment 2 : the 

 spiracular tubercle on segment 14 is a mere knob and that on segment 2 is 

 very short. On segments 2 to 13 is a small tubercle on the base of the leg 

 or in the spot where the base of the leg ought to be. The legs are shiny 

 black. The spiracles are longly oval and shiny black. The colour of the 

 body is a velvety, rosey black, marbled with satiny grey on the back. On 

 segments 7 and 8 is a diagonal rosey white band reaching from the base of 

 the subdorsal tubercle of segment 8 to the base of the spiracular tubercle 

 of segment 7. The subdorsal tubercle of segment 8 and the spiracular one 

 of segment 7 are both rosey-white with red tips. All the pointed 

 tubercles — for they are all pointed — are the same colour as the body, 

 with bright red tips. L : 90mm ; B : at broadest part (centre of the body) : 

 15mm ; H at the same place : 14mm ; L of the longest tubercle : 14mm. 



Pupa. — Head quadrate, top surface flat and sloping, front edge ridged, 

 straight, with a short, triangular, round-topped projection, pointing side- 

 ways. Segment 2 has a carination separating it from segment 1, is divided 

 into three trapeze-shaped portions which are flat, by two ridges — sub- 

 dorsal — converging towards the centre of the hinder margin ; slight-dorsal 

 ridge. Thorax is convex, nearly hemispherical, with a strong dorsal cari- 

 nation running from front margin to apex where it divides into two curved, 

 short, diverging ridges at right angles to each other, which latter two turn 

 in and soon become parallel, running thus to the hinder margin. The 

 thorax is short and the space between the two parallel ridges on its 

 hinder slope is flat. The shoulders have a diagonal ridge running to a 

 point towards the thorax apex. Segment 4 is in the same plane as the 

 back slope of the thorax, the' suspending string runs across its centre and 

 behind two extraordinary waxy looking small out-growths situated on the 

 wing-case line. The abdomen from this point to the end of segment 8 is 

 somewhat flattened dorsally ; the sides of thorax to where the suspending 

 string passes are parallel to each other, the wing cases are expanded 

 strongly in a curve from this point to the front of segment 8, the expansion 

 being broadest just before the hind margin of segment 7. The abdomen from 

 segment 9 (incl.) to the end is strongly curved down — a full quadrant of a 

 circle — the intersegmental membrane of segments 8/9, 9/10, and 10/11 show- 

 ing dorsally. Segments 8, 9, 10 have a subdorsal, laterally much flatten- 

 ed, contorted, pointed tooth, those on segments 8 and 9 being very large, 

 those on segment 7 being hardly developed. From the base of each tooth 

 of segment 9 a ridge runs to the base of the short cremaster. The ventral 

 line of the pupa runs at first from the head parallel to hinder slope of
