No 8. pedalis or s. ventralis. 



Abdomen 1, 2. V. dorsalia with two setae, so that I presume 

 s. dorsokiteralis has been added to them, s. subdorsalis, s. supra- 

 .ttigtnali!^, s. infrastigmalis and s. poststigmalis each of them with 

 one seta. V. basalis with two or three setae and on the place 

 where there is a leg in the segments 3 — 6 one setn = s. pedalis. 

 Seym. 3, 4, 5, 6 = 1, but one s. basalis is missing, whilst there 

 are along the outer and the lower edge of the leg mostly five 

 or six rather long setae (+'/2mm.) I consider these to be 

 the s. pedales. It may be possible, however, that the s. basales 

 of 1 agree with these s. pedales of segm. 3 — 6 and that 

 the seta there called s. pedalis really is a s. ventralis. This 

 supposition appears especially probable, when the caterpillar 

 is looked at from the ventral side and, starting from seg- 

 ment 3, we try to explain the arrangement of 4. If, on 

 the other hand, the caterpillar is looked at from the lateral 

 side and segment 1 is started from, we hesitate to give 

 the above explanation for segment 3. 

 , 7,8,9 = 1. 



„ 10^ 1. «S. dorsalis, close to it lies s. suprastigmalis. These 

 is a s. basalis and the setae forming together the s. pedales 

 are very strong and are + '/4 mm. long. 

 „ 11. Behind the setae of 10 there are on the anal flap three 

 more setae which are arranged in the following way: 

 s. dorsalis. s. subdorsalis, s. sujrrastigmalis. 



Instar //. Duration 10 days. Length 7 mm. The arrangement 

 of the setae is almost the same as during instar I. The setae 

 are not plumed either, but the tubercula are black and on 

 the front and the back edge of nearly all the segments there is 

 a black spot bearing many setae, which are smaller than 

 those on the primary tubercula. In the figure I have marked the 

 median spots with a darker colour than the paired ones. The 

 tubercula of the other side, which are visible on PI. Ill, fig. 10, 

 lateral aspect, are striped.
