Larva. 820 days old, p'U2)atcd. 



Previous to pupation the meso-thorax became much 

 enlarged dorsally and laterally, but I could perceive no 

 further alteration from previous descriptions. 



Fiijm. (Figs. 20, 21.) 



Length about 1| inches. Dark straw colour with reddish 

 spines. Lateral aspect : Head small, each succeeding 

 segment gradually wider to 7th abdominal. 8, 9, 10 form 

 a rounded extremity. 



Ventral aspect : Eyes prominent, elevated. Antenna> 

 short, extending very little beyond base of wing cases. 

 Second pair of legs form margin of wing cases, first pair 

 of legs inner to second, tips of third j^air between apices 

 of wing cases. Abdominal segments 2 and 3 are coalesced 

 on the ventral surface, the wing cases extend to anterior 

 edge of same. On 4 and 5, in the position of abdominal 

 feet of larva, are some minute probably inoperative spines. 

 On 7 a strongly developed anterior ridge of spines. S, 9, 

 10 are smooth on ventral surface. 



Dorsum. Part of head constitutes anterior extremity 

 of pupa. Prothorax small, with anterior margin of hairs 

 corresponding Avith those of scutellum of larva. Meso- 

 thorax very large with wing cases attached, trapezoidals 

 as on larva. Meta-thorax small, terminating laterally with 

 edge of fore-wing cases — which completely cover hind- 

 wing cases at base. Abdominal 1 is so small as to look as 

 tliough squeezed by meta-thorax and 2nd ; the latter has 

 trapezoidals, supraspiracular and subspiracular setoe as on 

 larva, the spiracle is wholly above wing-cases. 



Abdominal 4, 5, 6 have also the four abdominal-feet- 

 basal setae in addition to the trapezoidals, supraspiracular 

 and subspiracular set^e, all of which are well developed ; 

 4, 5, 6 also have the ventral inner seta^. 



Abdominal 2 to G have spiracles. 7 has only a spiracle 

 scar, and only two setae in position of larval subventral 

 seta^. 8 has only a spiracle scar and one subventral seta. 

 I cannot identify seise on 9 and 10. 



Abdominal 3 has anterior and posterior dorsal spines, 

 each succeeding segment has three spines extending sub- 

 laterally, but strongest on dorsum. 8 has only a few dorsal 

 spines, but very much stronger than those on the other 

 segments : these probably operate in conjunction with the
