Reddish brown in front above, and top of vertex brassy purple. Thorax 
obscure brownish. Legs black, paler basally. Wings hyaline with a touch of

brown, veined with yellow and the brown surrounded with yellow and with a 
large yellowish hyaline spot upon the middle of the hind margin. Stigma brown-

This is a very handsome broad winged, blackish, strong-flying species. Face 
pale, darker on labrum, metallic violet on top of frons and whole of vertex and 
occiput also metallic. Thorax scantily clothed with short whitish pubescence; 
obscure brown without distinct pattern; sides somewhat paler. Legs blackish. 
Wings hyaline, broad at base and pointed at apex with trapezoidal stigma aud 
brown basal markings, as shown in figure 00. Abdomen blackish, paler on basal 
segments with an obscure yellowish middorsal spot on middle segments, plainest 
on 7. Apical segments and appendages black. 
It flies through the greater part of the season. The pairs are often 
seen coursing the borders of ponds and ovipositing in early spring, and 
in August males are seen out on upland miles from water, foraging. 
They are exceedingly difficult to capture; but the nymphs are often 
found quite abundantly and are easily reared.
