Body elongate, rather slender, a little compressed. Head large, 

 prominent, nearly half as long again as the prozona. Vertex prom-

 frontal costa, the front half sloping downward, with a broad, median 

 furrow or depression. Frontal costa with the lower half much wider 

 than the upper; the region just below the ocellus concave. Antennae 

 about three-fourths the length of hind femora. Pronotum enlarged 

 a little in front to receive the head; the disk with the sides a little 

 sloping, the hind margin broadly obtuse angled; the median carina 

 rather sharp, of equal height throughout, cut by all three of the 

 transverse sulci. Lateral lobes of pronotum with the lower margin 

 obtuse angled near the middle. Tegmina either abbreviate or fully 

 developed. "\ATien the former, a little longer than the pronotum, 

 broadly lanceolate, the inner margins touching about the middle. 

 When developed, surpassing the hind femora in both sexes. Hind 

 femora slender, surpassing the tip of abdomen in male, a little 

 shorter in female. Abdomen compressed, carinate above, its apical 

 fourth thickened and curved upward in the male. Cerci depressed, 

 styliform. Furcula minute, triangular. (See Fig. 19, Plate II.)

 form of which occurs in northern Indiana.
