recurved teeth pointing anteriorly. In addition to this, all 

 segments 2 to 9 have near the anterior edge a row of strongly 

 chitinised spines directed caudally and arranged in a crescent- 

 shaped line. These spines are only slightly developed on 

 abd. 2 to 5 and 9, but are conspicuous on abd. 6^ 7 and 8, 

 reaching their greatest development on the last segment. 



On the ventral aspect abd. 4 to 6 show the scars of the 

 larval prolegs, and in addition, abd. 3 to 7 have a lateral 

 semilunar chitinous plate. Abd. 9 shows strongly developed 

 genital tubercles, while on segment 10 the cremaster is absent, 

 but the anal prologs have developed into two divergent, 

 flattened, conical plates, compressed laterally, and each ending 

 in a strongly curved hook directed ventro-anteriorly (text- 

 fig. 13, B, D). 



The abdominal segments show seta3, corresponding in 

 position to the primary setfe of the caterpillar. 



Female Pupa. — Length 20 to 23 mm., width 6 mm., sub- 

 cylindrif orm, with caudal end rather abruptly pointed, anterior 

 end rounded. Colour mahogany red (II) to hessian brown 

 (XIII). 



Pupa vermiform, without wing-cases, eyes, antennas or 

 distinct mouth-parts. Ventral aspect of head so greatly 

 wi'inkled as to obscure the parts of which it is composed 

 (text-fig. 13, h). Head deflexed and retracted under pro- 

 thorax. Legs rudimentary, showing as short, compact, 

 flattened, paired, free appendages on a broad base, arising 

 from the ventral aspect of the three thoracic segments. Pro- 

 thoracic spiracle obscure, other spiracles prominent. Ventral 

 aspect of abdominal segments smooth, scars of abdominal and 

 anal prolegs conspicuous. Dorsal aspect of thoi'acic and 

 abdominal segments transversely striate. Abd. 1 with a row 

 of minute hooks on the edge of the caudal declivity; segments 

 2, 3 and 4 have two similar rows of booklets, one at the 

 cephalic and one at the caudal end, while abd. 5, 6, 7 and 8 

 each have only one sinuate row of booklets near the cephalic 

 edge, increasing in size and prominence toward the 8th seg- 

 ment, on which they reach their greatest development. On
