Body slender, somewhat compressed. Head somewhat 

 swollen dorsally. Vertex with the lateral carinae converging more 

 rapidly than in Dissosteira. Median carina faint or wanting. 

 Lateral foveolse more distinct than in Dissosteira. Frontal costa 

 narrow, sulcate around and below the ocellus. Antennae about 

 as long as hind femora, slightly flattened towards the base. Pro- 

 notum with the disk much as in Dissosteira. The median carina 

 prominent, usually high and deeply cut in front of the middle 

 by a narrow notch. Tegmina considerably surpassing the ab- 

 domen in both sexes, the intercalary vein less prominent than in 

 the previous genus and nearer the median than the ulnar vein. 

 Inner wings with the base yellow, bordered by a dark median 

 band. Hind femora rather stout, nearly reaching (female) or 

 surpassing (male) the end of the abdomen. Hind tibiae in our 

 species with considerable red.
