al)()ut 500 ,a. Tu otlier words: while thv Caterpillar only 

 grows 50°/q, the f. dorsales^ which soon becomc united, 

 havo attained a lengtli of ten times thcir original onc. 

 Seyin. 9. J'^. dormVts is very large y\\ih.ïoviV ^et^iQ^v. supraHtujmaiis 

 is reduced to one seta; s. subdorsalis has disappeared, as 

 also have s. poststigmalis and s. infrastigmalis ; v. hasalis 

 with four setae ; two setae on the ventral side I should like 

 to call 8. propedalis and s. vent rails. 

 „ 10. V. dorsalis upon the anal flap with four setae, below 

 it a very large verruca, which has possibly taken origin 

 froni a consolidation of i\ siiprastigmalis and v. hasalis 

 (five setae) ; two s. propedales^ s. ventrales. 

 No 11 til Abdominal segment can be detected. 

 Instar //. Duration a fortnight. Length 8 mm. 

 On the whole the same verrucae as in instar /, but whilst 

 there they are distinctly confined and have dark pigments, here thoy 

 consist of a small elevation of the surface, of the same colour 

 as the rest of the body. Upon this elevation stand a number of 

 setae, which are about 400 /^ long and which therefore have 

 not grown. The whole surface is covered by irregularly spread 

 secondary setae, about 100 ^ long and therefore distinctly con- 

 trasting to the primary ones. 



Prothorax. Verruca dorsalis with five setae, s. subdorsalis^ s. 

 dorsolateralis, v. suprastigmalis with two setae, v. prostigmalis^ 

 with four setae, v. hasalis with five setae, s. propedalis^ s. post- 

 pedalis, s. ventralis. 



Mesothorax. V. dorsalis with six setae, v. dorsolateraUs with 

 four setae, v. suprastigmalis with three small setae or already to- 

 tally vanished, v. hasalis with five setae, 8. propedalis^ s. post- 

 pedalis^ s. ventralis. 



Metatliorax = mesothorax^ but c. suprastigmalis has almost dis- 

 appeared. 



Ahdomen 1. V. dorsalis with two to four setae, s. subdorsalis, 

 r. suprastigmalis with four setae, no v. or s. poststigmalis and 

 infrastigmalis, i\ {pro)pedalis with four setae, s. ventralis.
