These are Sonoran dragonflies of singularly beautiful coloration. The 
dark thorax is covered with vermiculate lines of dull yellow, and the 
dorsum of the abdomen bears on its segments a series of V’s of the 
same color. The wings are heavily clouded with brown. The triangle 
of the front wing is very long and narrow and followed by four or more 
rows of cells. The post nodal cross veins near the front of the stigma are 
strongly aslant, simulating brace veins. Vein M2 is strongly undulate. 
The heel of the anal loop is very large with a spur vein running out 
into it. The nymph is unknown.
