This rather small colorful genus of eight species is found only in Eastern North
America. The lateral thorax is usually striped in black on a pale background. On
the mid-dorsal thorax also occurs a black stripe. The thin abdomen is somewhat
compressed in the basal segments and patterned in colors of yellow, red, orange
and black. All have diagnostic wing patterns of bands or patches making identification
fairly simple. The base of the hindwings is broad. The face generally has some
yellow tint but may change to red or black in the mature male.
The sexes have similar wing patterns but the females are usually duller overall.
