Thoracic appendages : Legs as described in type ; first legs about twice 

 as long as labial palpi ; second legs constricted in their middle one-third 

 by the first legs and maxillae, about one-third as long again as the first, 

 and terminate just above tips of fore wings ; second legs terminate just 

 below the junction of segments 6 and 7, about half-way between the ends 

 of second legs and antennae. Fore wings reaching about the middle of 

 the fifth segment, pointed, and slightly incurved. Prothorax constricted 

 mid-dorsally. Mesothdrax as in type. Metathorax as in type, wings 

 not extending beyond first segment. Abdominal segments, spiracles, and 

 setae as in type, also the thoracic setae. The first abdominal segment 

 bears only the dorsal pair of setae. All the setae are directed caudallv. 

 There is a slight lateral ridge on segments 2-8 inclusive. The dorso-lateral 

 seta is situated just dorsal to the ridge, below the level of the spiracle, is 

 shorter than the lateral seta, which is situated close against the dorsal 

 margin of the wing in segments 2-5, and caudal to the spiracle. On 

 segments 5-8 inclusive there is a second rather more prominent lateral 

 ridge, ventro-lateral and parallel to the other ; the lateral seta and spiracle 

 are situated between these two ridges. 



The pupa is very active if disturbed, twirling its abdomen in great haste ; 

 movement occurring between segments 4-5, 5-6, 6-7. Segment 9 bears 

 only the dorsal pair of setae, while 10 bears no setae at all, but has a short 

 pair of fleshy tubercles ventrally, each armed with a minute hook ; there 

 is a pair of minute tubercles dorsally, while caudally the segment is pro- 

 longed into two fairly stout finger-like protuberances, each armed with a 

 minute hook at the tip. 



Colour of pupa before dehisence : Head black, eyes dark red, ventral 

 appendages black with white markings, mesothorax black, metathorax and 

 abdominal segments light grey. 



Chief Measurements of Pupa. 



Dehiscence. 



The pupa is extruded through the upper cuticle of the leaf as far as 

 the third or fourth abdominal segment. The legs become separated in 

 one piece on either side, but remain attached at their lower extremites by 

 small slips. The front, with cephalic plate, eyes, labial palpi, maxillae, 

 and antennae, remains in one piece, but is not lost. Dorsally there is a 

 rupture across the epicranial suture, thus freeing the front and its append- 

 ages, and down the mid-dorsal arm of this suture, extending through the 

 prothorax and upper two-thirds of the mesothorax.
