A large dark Argia found most commonly in the central and southern states. 
Male.—Face dark brown, with black basal markings on the labrum and the 
postclypeus. Top of head predominantly black. Brown postocular spots rather 
small for Argia. Black middorsal thoracic stripe wide. Pale antehumeral stripe 
irregular from one-third (young) to one-twelfth (old males) as wide as the black

two fuse to become even five times as wide as the pale antehumeral. A heavy 
black line on the third lateral suture. Both the head and thorax are covered 
with unusually long white fine hairs. Wings with the stigma surmounting more 
than one cell in about 4514 of cases only. Abdomen with segments 2-8 almost

of black. Segment 10 predominantly dark.
