Nineteen males and seven females were taken. The males 

 are very conspicuous, and easy to capture, as they sit poised 

 on the long grass and sedge growing on the damp hill-slopes 

 at the top of the watershed. Their flight is not strong, though 

 their wings move rapidly. The females are much rai'er than 

 the males, and much less conspicuous.
