setae), while the subventral plate is wanting. The aual plate 

 on abd. 10 contains fonr seta3 on each side, three of which are 

 marginal. The anal legs are almost entirely surrounded by 

 a chitinous ring bearing three setae on its lateral aspect, one 

 on the median, and four setje on its caudal aspect. The 

 booklets on the anal legs are longer and more robust than 

 those on the abdominal legs and are eight to nine in number. 

 The skin behind and between the anal legs is furnished Avith 

 numerous small sharp-pointed papillae. 



Second Instae. 



Length of larva 6 mm. Ground-colour of caterpillar liesh- 

 colour (XIV). Head, thoracic shields and plates, coxte, 

 thoracic legs and anal plate and leg-plates of anal prolegs 

 light seal brown (XXXIV), setiferous plates on 8th and 9th 

 abd. segments chestnut brown (XIV), those on the other 

 segments russet (XV). 



The thorax has no longer the preponderance in size which 

 was so conspicuous in the first instar; the widest part of the 

 larva is now at the second abdominal segment, from which it 

 tapers gradually, both cephalad and caudad. 



Head. — Width of head-case 083 mm. Head resembles 

 that of the first instar larva, but the suture between frons 

 and clypeus is now indicated. Adfrontals still fused with 

 parietals. Head uniformally coloured ; no pattern is yet 

 apparent. 



Thorax. — On that part of the prothoracic shields corre- 

 sponding to the prespiracular wart two more setse have 

 appeared, one dorso-caudad, one dorso-cephalad of the 

 original (PL XLVI, fig. 7). The subventral plate has also 

 gained one seta and now bears three. On meso- and 

 metathorax additional setae have appeared on the pre- 

 spiracular (subspiracular) plate, and a minute one just in front 

 of this, while the setse on the subventral plate have increased 

 to thi'ee. 

 Abdomen. — On the abdominal segments the subventral plate
