Subfamily HYLAEINAE 



The females of this subfamily, like those of the Australian subfamily Euryglossinae and most 

 of those in the chiefly Neotropical subfamily Xeromelissinae, lack scopal hairs and transport pol- 

 len in the crop. The subfamily Hylaeinae is represented in North America only by the genus 

 Hylaeus. The species of this genus make cells of a transparent cellophane-like material in preex- 

 isting burrows, hollow stems, holes or cavities.
