This is very similar to auripennis differing by the darker metallic coloration 
of face above and vertex, and by the redder hue of stigma and adjacent veins. 
Perhaps it is hardly more than a variety of that species.

Calv. ’07, p. 201: Mtk. Cat. p. 135: Ris ’10, p. 272. 
Length 50 mm. Expanse 80 mm. Mont., Wyo. to Tex., Mex. and Calif. 
A large western species, similar to cyanea, having the same bicolored stigma 
(three quarters yellow) and a less development of the basal brown streaks on 
the wing. Body pattern wholly obscured by pruinosity, with age, as in that 
species. Face wholly yellow. 
According to F. G. Schaupp, dragonflies of this species sit mostly 
on green bushes at the banks, and fly, mostly over the surface of the 
water, hunting, and chasing each other, and (to the disappointment of 
the collector) disturbing other species that might easily be taken but 
for their continual interference.

Length 43 mm. Expanse 74 mm. N. H. and Ind. to Ga. 
A slender species with bicolored stigma. Face yellowish becoming shining 
metallic brown on labrum top of frons and vertex, with age. Thorax thinly 
clothed with short brownish pubescence; at first pale brownish and yellow, with 
age becoming pruinose blue all over thorax and abdomen. Front of thorax brown 
with yellow middorsal stripe, furcate at crest. Sides yellow, except around leg 
and wing bases, with a single brown stripe on the last lateral suture (stripe 5). 
Legs blackish, paler at base. Wings hyaline except for short basal subcostal 
streaks. as shown in figure; stigma yellow over more than basal half, beyond 
blackish. Abdomen at first pale brown yellowish below on the swollen basal 
segments; above with a continuous broad line of yellowish that begins high up 
on dorsum of segment 2 and ends low down on sides of 9 and 10. Appendages 
brownish, becoming black. 
Brimley (’03) found the tenerals occuring “mostly among broom- 
straw in woods and fields, the adults fly over marshes and standing 
water.”
