broader than the tarsus and two-thirds as broad as long. Posterior 
pair of legs slightly longer than the second and third pairs. The 
femora of the last two pairs of legs are each provided with a triangular 
tooth on their posterior margins near the base. The tarsi of the three 
posterior pairs of legs are all very long and tapering. 
Length, 0.40 mm.; breadth, 0.388 mm.

Color reddish brown; margins of the body darker than the rest of 
the body. Integument thick and with shallow pits; pits, though rather 
evenly distributed, are somewhat irregular in shape and size. 
Mouth-parts rather small and hidden by a slightly projecting an- 
terior, roundly curved, margin of body. 
Body almost as broad as long, subcircular in outline with margins 
slightly roughened. Body clothed above with hairs that are unique 
in their structure. They each possess a single stalk-like base, but this 
basal stalk is soon resolved into three or even four elements. Of these 
different elements one is always much larger than the rest, and may 
be considered as composing the main body of the bristle. The other 
smaller elements which arise not far from the base of the bristle, 
extend along the larger one like whip-lashes. These bristles are ar- 
ranged as follows: there are two rows of seven bristles each which run 
longitudinally, one on each side of the median line; a row of marginal 
bristles which completely encircles the body, of these there are about 
thirty; about an equal number scattered over the upper surface of the 
abdomen in no special order or arrangement. 
Genital opening of the male large, circular and situated behind the 
last pair of coxae! Epigynium of female very long, fully twice as 
long as broad, extending from the front margin of the second coxae to 
the hind margins of the fourth coxae. It is widest near its middle 
and is narrowly rounded in front and truncate behind. 
Excavations for the legs moderate, but snugly containing them when 
folded. Last three pairs of legs subequal. The femora are the stoutest 
segments while the tarsi are long and tapering. 
Length, 0.52 mm.; breadth, 0.42 mm.
