pillars. Thore is also a large r. hasalis^ and sonie iion-pluiiiod 

 setae on the leg. 



MesotJtomx and inetathorax. We find v. dorsalis^ v. suprastig- 

 malis and v. jn-ostifjmaUs which are aboiit equally large. The 

 last mentioned wart lies on the sarae height as the very high 

 placed V. poststigmalis on the abdominal segments. V. dorsolate- 

 ralis is wanting. 



Behind r. prostijjmalis is a small tubercuhim with three or four 

 setae. It lies therefore on the place of the wing-rudiment. Besides 

 we find in many individuals a tuberculum with one or two setae. 



V. hasalh is large. On tlie leg occur some setae which are not 

 feathered. 



Ahdomen 1, 2. V. doisah's is a little smaller than v. fiuhdor- 

 salis^ V. suprastiginalis is large. Large and far projecting is v. 

 poststigmalis which is partly continued under the stigma towards 

 the head. V. infrastigmalis is situated lower than in most of the 

 othcr families of caterpillars. V. hasalis and v. pedalis on the 

 place where on the abdominal segments the leg is fixed. 



Segm. 3, 4, 5, 6=1, except that v. pedalis is absent. But on 

 the leg are one or two strong setae. 



„7,8 = 1. 



„ 9. Very small l\ dorsalis, very large v. suhdorsalis which 

 has far extended in the direction of the missing v. suprastigmalis, 

 this being perhaps united with it. For the rest as 3. Moreover 

 there is a rather large tuberculum under the anal flap. I con- 

 sider this to be v. infrastigmalis of segm. 10. 



Consequently the lOth segment is very mucli roduced. 



Instar II. Duration 30 days. Length 12 mm. 



The wholo animal looks exactly as in instar /, but between 

 the tubercula a few setae (generally not plumed) are found. 



Prothorax. V. dorsaUs is still larger than in instar I and i\ 

 subdorsaUs too has grown longer. Under it is a new verruca. 

 For the rest as in instar /. 



On the abdominal segments we see some small tubercula in 

 the neighbourhood of y. infrastigmalis. V. posfsfigoadis now grows
