II. RECREATOR GROUP 



Head, thorax, and coxae with hairs usually of moderate length, 

 and except on temples the hairs usually decumbent; temple smooth or 

 weakly mat, ■s\-ith distinct punctures, not rugulose; frons usually with 

 a depression dorsolaterad of each antennal socket which varies from 

 a deep pit to a faint impression ; front tarsus of female often widened ; 

 areolet irregularly pentagonal, its outer side usually shorter than 

 inner side; second recurrent vein simply arched, rather short; axillus 

 vein distinctly divergent from margin of hind wing; abdomen fulvous 

 or ferruginous to black, seldom iridescent. 



This is a Holarctic group. Its species are usually" in mountainous 

 areas, where there is bare soil. Males cruise about scattered bushes 

 with a fast, undulant flight. Females are more often seen crawling 

 over ground with sparse vegetation. There are nine species in Amer- 

 ica and apparently a larger number in Eurasia.
