space, the edges of the space being demarcated by a dark line ; rest of 

 pit yellowish brown. Vasiform orifice similar in shape to pit, edges 

 dark brown. Operculum broader than long, anterior edge flat, posterior 

 edge concave, sides convex ; colour brown. It extends to a little beyond 

 centre of vasiform orifice. Lingula broad for its length, dumb-bell- 

 shaped, being constricted in centre, tip spatulate. It projects for about 

 half its length beyond operculum ; colour brown. 

 Larva 3rd stage. Size '76 mm. x '46 mm. 

 Apparently similar to the 4th stage. 

 Larva 4th stage. Size *85 mm. x # 5 mm. 



Shape as in pupa. A short marginal fringe of wax. Vertical 

 fringe short. Dorsum much blotched with black. Rest apparently as 

 in pupa. 



Puparium. Size 1*1 mm. x '68 mm. 



Shape elliptical, narrower cephalad, the margin being rather abrupt- 

 ly incurved at thorax. Margin caudad flattish. Cephalothoracic area 

 lemon yellow, later turning to orange. Last three segments of the 

 abdomen up to vasiform orifice orange. There is a clear space between 

 these two patches. Two irregular longitudinal grey bands on anterior 

 segments of the abdomen just without the central double row of pores. 

 A broad edging of black around cephalothoracic margin. This is in 

 some cases interrupted so as to form three separate patches, one cephalic 

 and two thoracic. The cephalic patch is divided into two by a narrow 

 yellow band which connects the cephalic margin to central yellow area. 

 A black edging on margin caudad. Caudolateral margins more or less 

 blotched with black. Rest of body of a cream white colour. The grey 

 edging on margin is not at all constant, it varying a good deal. As 

 the insect within develops the markings gradually disappear. They 

 disappear very irregularly, in many cases blotches disappearing from 

 one side before the other. The caudolateral marginal blotches dis- 

 appear first. The suture between thorax and abdomen sometimes 

 apparent as a fairly broad transparent band. There are 26 seta3 

 right around dorsum ; they are set just within the margin. The 

 upper end of each seta for about one-third of its length surrounded 

 with a quantity of fluffy wax. Of these setae 14 are situated on the 

 abdominal and 12 on the cephalothoracic region. The spines are 

 comparatively short ; colour light brown. Two long setse caudad on 

 margin on a slightly lower plane than the marginal fringe of spines. 

 Mesad of the marginal spines there are present on the dorsum two 

 series of large pores an inner and an outer series. There are in all 28 

 pores in the outer series, 12 on the abdominal and 16 on the cepha- 

 lothoracic region. The pores on the abdominal segments are situated,
