Ninth dorsal abdominal segment only moderately extended, 
a little flaring, the hind margin sometimes appearing slightly 
emarginate. Subgenital plate obtuse-angulate emarginate from 
rear, convex or nearly rectangular from side. Hind femora 
stout, convex above and below, often unarmed in female, usually 
with a few tiny denticulations on the apical half, more prominent 
on the inner edge; hind tibiae straight. Hind thighs brown, 
punctate with pale; front and middle legs and hind tibiae pale, 
the large spines on the latter blackish at base. 
In color this is our most striking species. The dorsum is 
black, with the top of head and a narrow mid-dorsal stripe on 
the thorax, breaking up on the abdomen, chestnut. Eyes dark; 
face, cheeks, and sides of the thoracic segments white, the lower 
thickened margins of the latter chestnut.
