The specimens taken are all males, and have their heads armed 

 with sharp horns. One specimen has the antennae testaceous; in 

 the others the tip of these is pitchy, as in foreign examples. The 

 mouth is red, and the head and thorax are black, excepting the 

 rufous margins of the latter.

 other Diptera, that are accustomed to hover over pools.
