Related to C. latens but superficially unHke. New England 
examples before me are chiefly very dull and uniform brown, the 
dark latero-dorsal stripes so conspicuous in C. latens usually 
lacking, present but not strongly developed in one example. 
1^ This is a small and moderately slender species, the hind thighs 
three and a half times as long as wide, a little convex beneath, 
and armed with a very variable, irregular series of usually widely 
set, short, appressed teeth, smaller on the inner edge and in the 
female castaneous, 
often with few or no 
markings. Hind tib- 
iae slightly exceeding 
the femora, pale, 
spines dusky at base 
and tip. Ninth dor- 
sal segment distinctly 
prolonged backward, 
truncate -convex. 
Subgenital plate of male V-emarginate from the rear, rounded 
from the side.
