Prevailing color, chestnut-brown. Head pale, a few short 
stiff bristles upon a protrubence on the vertex, and down sides 
of the face. Antennae four-fifths the length of body; basal seg¬ 
ment stout, naked; second four times as long with a few long hairs 
distally; third equalling the first two with distal half; divided 
into seven distinct sub-segments, and three others less evident 
swollen terminal ones; each sub-segment with a pair of hairs, a 
few hairs near the base of the third joint; fourth segment equal¬ 
ling basal in length, with whorls of long hairs. Eyes black. 
Body, abdomen ovate dorsally, dilated at sides; dorsum darker 
with several long, white bristles anteriorly, and very short 
bristles posteriorly; anal tubercle with long, stout bristles. Legs 
long, slender ,spiny, especially on tibia. Claws, superior one

midway between it and the tip, a third tooth on the outside 
nearly opposite the last; inferior claw with straight, tapering 
sides, and an apical hair hardly longer than the other claw; the 
extreme tip of the claw free from the hair. On the inside of the 
inferior claw, near the base is a dilation whose apex bears a short 
bristle. Furcula pale, extending beyond the ventral tube; man¬ 
ubrium stout; each dentes with a row of long spines on either 
side; mucrones tapering, one-third the length of dentes, coarsely 
serrated beneath. Length 1.6 mm. Habits, reported by Fol¬ 
som as living on the under side of pine logs, and eating the wet 
decayed wood. 
This species has been reported only by Folsom from Arlington, 
Mass., the description being taken from twelve specimens found 
during October and November. Concerning the habits the 
author further says, “The last specimens found before a severe 
frost were all females which laid numerous eggs in captivity 
when given natural conditions of moist food, air and darkness. 
The eggs, laid singly, were spherical, with strongly flattened 
ases, translucent white, smooth, .3 mm. in diameter, .15 mm. 
igh, and with embryos quite undeveloped several days after 
eposition.”
