Segm. 2=1, but s. subdorsalis is absent. 



„ 3, 4, 5, 6 ^ 1 . but 8. subdorsalis is absent, v. infrastigmalis 

 often consists of one or two setae; and on the segments 3 

 and 4 there is often a v. poststigmalis with four setae; 

 V. basalts with six setae; the pigmental spots on the leg 

 have increased in size and bear many short setae. 

 . 7 = 1. 



„ 8. The ''caudal horn" has become entirely median, and its 

 formation by the blending of the two v. dorsales is no 

 longer clearly visible. It is now 600 f^ high, perhaps s. sub- 

 dorsalis is united with it, else it has disappeared ; further 

 there occur v. suprastigmalis with three setae, v. basalis with 

 four setae, v. ventralis with two setae, of which the most 

 lateral oae is perhaps s. propedalis. 

 „ 9. V. dorsalis is formed by the union of the right and the left 

 one. It is now 300 f/,. high and resembles that of segment 8, 

 but is smaller ; no s. subdorsalis, s. suprastigmalis^ v. basalis 

 with four setae, s. propedalis^ s. ventralis (see abd. 8). 

 „ 10. F. dorsalis, with four setae; s. subdorsalis; one spot 

 with setae under the anal opening, probably agreeing with 

 V. basalis, s. propedalis and on the leg three s. pedales. 

 Instar ///. Length 9 mm. 



In these and the following instars all verrucae and setae remain 

 entirely as during instar//. To prove this, I drew the abdominal 

 segment 5 of instar V, i. e. after the last moulting (Length 40 mm.). 

 Distinguishable are still : v. dorsalis, with three setae, placed imme- 

 diately beside that of the other side and behind this a black 

 spot; s. subdorsalis, v. suprasfigmalis with three setae; v. basalis 

 with five setae. Further the whole leg is covered with long setae ; 

 namely more than 1000 y. long, whereas the remaining primary 

 setae are about 500 jct., and the secondary ones about 100 [x. 

 So we see that a very insignificant growth of the primary setae 

 has taken place, namely of 400 — 500 (z., whereas the body has 

 grown from 4 to 40 mm. and during instar V to about 80 mm.
