 the corbicula and auricle, which distinguish the 

 posterior tibial and plantse of the aculeate sex of

 arities which will appear upon a comparison of their 

 respective characters. 



The species which I have arranged under the 

 first section of this family, belong to the genus 

 Eucera of Scopoli and Fabricius, so named from
