that it is not allowed to honiologize a primary with a secondary 

 seta. The many caterpillars in the coll. Kall. agree with Fracker's 

 groups. As examples of the 4th group 1 mention Acroni/cta ahii, 

 where the s. snlidorsales reach a great length and Diloba cocni- 

 locephala L. 



I should like to propose a 5th group viz.: 



V. The setae or the verrucac have disappeared, the pigmental 

 spots on the tubercula remain, e.g. Nonayvia {Deptrsmria) nervosa.

It is therefore quite like type I.

I only want to draw attention to the following segments which, 

 side by side of the verrucae I am going to mention, also have 

 secondary setae, especially on the ventral half. 



Metathorcur. V. dorsalis^ v. dorsolateralis, v. suprastigtnalis, some 

 *\ prosiigmales, v. basalis, some s. propedales. 



Abdamen I. V. dorsalis has grown enormously and has blen- 

 ded with that of the other side to a fleshy stump. V. subdorsalis 

 small, but still recognisable, v. suprastigmalis, s. prostigmalis^ 

 s. basales^ v. pedalis. 



Segm. 2=1, but without a horn, v. dorsalis is smaller than v. 

 subdorsali§.
