and Ichneumonidae. The calyx in Symphyta is not existing. The greatest 

 similarity between Syrtvphyta and Aculeata is based on the double tracts 

 which connect the corpora pedunculata Avith the lobus oHactorius. The pedun- 

 culus with its anterior and medial roots differs considerably from that in 

 Aculeata. Special attention deserves the fact that in Symphyta the part homo- 

 logous to the calyces in Aculeata is really more similar to this organ in other 

 insects than in Hymenoptera. And so, e. g. we find much similarity to Sym- 

 phyta in species of some families of Coleoptera {Osmoderma, Oryctes). 



As regards higher functions of the insect they cannot be dependent wholely 

 on the complexity, or even on the size of the corpora pedunculata in relation 

 to the brain. A great role is played here by the size of the Avhole brain in relation 

 to the size of the insect, in spite of certain fluctuations connected also with 

 the decrease of the dimensions of the body.
