distiiictly visible. ün the nicso- and nietatliorax rlia/. (/ors(di^, 

 ciml. (lofsolateralis and chal. suprastigmalis are united. 



We can still recog-nize the priniary tubercida on the abdominal 

 segments, though vIkiI. suprastigmalis has become doublé. The 

 arrangement in cross-rows is more striking tlian that in horizontal 

 ones. Distinct are e. g. on abd. segment 5 : chal. doi'saUs, chal. 

 suhclorsalis, a doublé chal. suj)rastigmalis (oral of it a large tubercle), 

 s. 'postMigmalis and 6-. infrastigmaUs. Many s. hasales, and under 

 chal. subdorscfl'is a large new chalaza. 



Instar VI = Chri/salis. As J. F. van Bemmelen (1912, p. 114 

 and fig. 6) has shown, we can compare the spots of the pupa with 

 the chalazae of the caterpillars. 



This is especially clear when the stigmata are examined. I feel 

 justified in designating the spots as follows : the spot under the 

 stigma as macula infrastigmaUs^ that behind it as m.poststigmcdis and 

 taking this for granted, the lowest of the four spots over the stigma 

 as m. suprastigmcdis. I see the proof of this in the oral and ventral 

 enlargements which this spot shows on some segments, agreeing 

 with the two chalazae, so distinctly developed in instar V. 



The uppermost of the same row seems to me to be in. dorsalis 

 and the doublé spot in the row caudal to the one I have just 

 discussed, I consider to be iii. snhdorsalis^ which is also doublé 

 in instar V. 



From this point of view the spot under it may obviously be 

 considered as the large one under in. sid)dorsaJis which has 

 appeared in instar T^ 



The rows oral of the first-mentioned and caudal of the last- 

 nientioned one agree entirely with those of tlie Caterpillar. 



We must still explain the spot, generally large, ventral of the 

 stigma, lu my opinion this is the in. basal/s, which has iiearly 

 become irrecognisable in instar r; and ventral of it a narrow, 

 elongated spot agrees with the row of the .s'. pcdalcs. 



It is more dithcult to explain the two spots between in. dorxalis 

 and III. siiprasflgiiialix. Tlic more dorsal o\w of these two we may 

 take as a j)art of iii. dorsalis^ which also in the larva oftcii bears
