Vertex prominent, the basal two-thirds broad, the lateral carinas 

 distinct, suddenly converging opposite the front half of eyes, but not 

 uniting in front; the median carina low, reaching center of disk; 

 traces of a cross carina on posterior half of disk in female; foveolse 

 small, elongate U-shaped. Frontal costa rather narrow, sulcate from 

 a little above the ocellus to the base; the upper third narrower, punc- 

 tate. Antennae a little shorter than head and pronotum in the fe- 

 male; equaling their length in the male; filiform, the joints a little 

 flattened. Pronotum with its disk flat, a little wrinkled on the pro- 

 zona, covered somewhat regularly with small rounded tubercles, these 

 more prominent in the female; the hind margin right-angled in the 

 male, obtuse-angled in the female; the median carina low but dis- 

 tinct, cut in front of middle by the principal sulcus, the lateral 

 carina distinct only on metazona. Tegmina of both sexes surpassing 

 the abdomen; the basal lobe of lower margin noticeably expanded, 

 especially in the female. Hind femora broadly dilated; the upper 

 and lower carina much elevated and sharp. 



General color, ash or reddish brown; the males darker. Face ash 

 brown or clay yellow. Occiput and disk of pronotum dark brown. 

 All of these parts, as well as the upper and lower outer faces of the 

 hind femora are often prettily tinged with greenish. Tegmina, ash 

 brown, with numerous large dark brown or blackish spots; those of 

 the female more distinct, the light interspaces being wider; the 

 largest of these spots on the lower third being just behind the ex- 

 pansion noted above. Wings deep orange (rarely yellow) at base; 

 outside of this and just beyond the middle a curved black band 

 crosses from the costal margin to the anal angle; the apical fourth 

 transparent and smoky, the extreme tip with one or two fuscous 

 blotches in the male; a humeral bar or stripe of black reaches nearly 

 to the base of the front portion. Inner face of hind femora deep 

 blue, with an orange bar near the apex; outer face reddish or yellow-
