Yon Ihering gives an important paper on the stingless bees of S. America 
under the following headings : 
1. Special biology of Meli^ona and Trigona. 
2. General biology of Mehponides. 
3. Rearing : the products and vernacular names of Brazilian bees. 
4. Comparative biology of social and solitary bees.
