This species is recognizable at once by the basal curvature of 
the hind tibiae of the male, and the peculiar, angularly excised 
border of the ninth dorsal segment of the abdomen. The hind 
thighs are stout, convex above and beneath, the distal two- 
thirds of the ventral edge armed with 10 to 20 stout, irregularly 
disposed and uneven spines. Hind tibiae of male strongly arcu- 
ate on basal third, straight 
or faintly curved beyond, 
slightly longer than the 
thighs. Subgenital plate 
truncate, divided b}' a me- 
dian fissure, each half with a 
sinuate terminal border, form- p^^ go.^potted Cave^ricket. CeuihophUus ma-

This seems to be our most generally distributed Cave-cricket, 
and is of common occurrence in cellars as well as out-of-doors 
beneath logs, stones, and loose bark of fallen trees and stumps. 
Though commonly met with in groups of two to five, colonies 
numbering a dozen or two are occasionally found. Nymphs are 
most common in early summer but may be found at almost any 
season; adults are most numerous in August and September,
