Antennae 12-segmented, hair-brown, the last two or three 
segments and sometimes the base pale yellowish brown, the 
segments subcylindrical or fusiform. 
Pronotum as long as head but narrower, rounded posteriorly; 
tegmina as wide as pronotum and nearly twice as long, obliquely 
truncate posteriorly. Exposed part of wings half as long as 
tegmina, rounded postero-laterally. Exposed part of abdomen 
varying from one-third as long to equal to the tegmina. Hind 
margin of last dorsal segment of male with a pair of small tubercles 
near mid-line. 
Forceps of male about four-fifths, of female about two-thirds, 
as long as tegmina, of male widened internally near base by a 
slight angular process, separated at base by a space nearly equal 
to their basal width, arcuate, their inner margin roughened by 9 
or 10 minute, backward-pointing denticulations; of female a 
little shorter than in male, flattened at base, attingent through- 
out, without denticulations. In the male a chitinous, back- 
ward-pointing process arises from the middle of the last visible 
ventral segment, its ventral margin curving gently upward to 
the tip. 
Head and sides of abdomen dark brown, deepening to blackish. 
Pronotum, tegmina, and exposed wing-tips light to medium-dark 
hair-brown. Forceps and dorsal median third to half of abdo- 
ment chestnut, deepest on forceps, rarely with a transverse dusky 
cloud midway between tips of wings and base of forceps.
