In this paper Mayr gives diagnoses of numerous species of 
Geocores belonging to the tribe Bcutata, most of which are 
types of new genera, and also characterizes several new generic 
groups founded upon known species. The characters of these 
genera and species are published by Mayr for the purpose of 
securing his priority. The insects described form part of the 
material for the entomological section of the zoology of the 
voyage of the ' Novara.^
