Not illustrated. 1897 Excerpt: ... costa is more or less rounded above the ocellus, plain or very faintly sulcate below with the sides sub-parallel. The antennae are decidedly flattened at the base and much longer than the head and pronotum together, in the male as long as the hind femora. The face seen from the side is nearly straight. The pronotum has the disk plain with the three carinae equally distinct and cut much behind the middle with the last transverse sulcus. The lateral carinae are plainly (male) or strongly (female) curved. The posterior margin of the metazone is straight or gently curved, not angulate. The lateral lobes of pronotum are longer than high, with the anterior and posterior margins straight and strongly and equally oblique, and with the lower margins horizontal or slightly descending posteriorly, more decidedly ascending anteriorly. Mesosternal lobes separated by a space much broader than long, the metasternal lobes by a space broader than long (female) or about as broad as long (male). The tegmina are generally abortive (female) or well developed (male). The scapular area is unusually expanded, especially near and beyond the middle in the male (and in the female to a less extent when the tegmina are not abortive), and is filled with a series of strong oblique cross-veins. The discoidal is as broad as the ulnar area, and the intercalary vein is present. The posterior femora are rather slender or moderately robust and more or less distinctly banded above. The posterior tibiae have the apical spurs on the inside about equal. This North American genus contains two species, one from the north-eastern and one from the north-western United States.
