of the 1th abdominal : a narrow strip of the hindwing extends to the pos- 

 terior edge of the 3rd abdominal : Poulton's line cuts off a very narrow strip 

 only. The spiracles are conspicuously elevated, position on 2nd abdominal 

 almost dorsal, on other segments placed rather high ; colour black ; shape 

 oval. The abdominal incisions are distinct and sharp ; the anterior edge 

 of the segments has a flat sloping rim. and all are covered with innumerable 

 minute pits, which Quail considers are probably associated with the fine 

 larval hairs. The pupa has no power of movement. Quail writes that he 

 could find no trace of setae corresponding to the tubercle-setae- of the larva, 

 but this is a mistake. During an early period of the pupal existence— 

 that is to say, before the yellow abdominal areas become obliterated — groups 

 of minute hairs may be found on the black areas, and these correspond with

the larval tubercles, as I have shown on the 5th abdominal segment only in 

 the figure. Further than this, the larval prolegs are represented by slight 

 depressions on the ventral surface of the segments ; these depressions bear 

 groups of minute bristle-like hairs. The terminal segment is round and 

 blunt ; the anal armature consists of 2 sets of hooks, 12 each, at either side 

 of the dorsal posterior extremity. The prothorax bears a central strong 

 longitudinal ridge, which extends into the frontal headpiece and mesothorax. 

 The antennae extend as far as Poulton's line, and form a slight prominence 

 on the ventral surface, as can be seen when the pupa is viewed from a lateral 

 aspect. Segmentation is very plain. The maxillae are comparatively
