est and broadest. Mandibles one-half as long as the palpi. Dorsal groove 
extending backward slightly beyond the level of the eyes. Two pairs of 
eyes present, the larger, posterior pair, situated one-half the distance 
from the dorsal groove to the lateral margin of the cephalothorax; just 
in front and lateral to this pair of eyes is a much smaller pair of eyes.

the third pair of legs. Body rather sparsely clothed with short, feather- 
like hairs. 
Anterior pair of legs one and a third times as long as the body; tarsus 
swollen, two thirds as long as the tibia; tibia narrower but equal in 
length to the antepenultimate segment. Second pair of legs slightly over 
two-thirds as long as the anterior pair; third pair slightly longer than 
the second. Last pair of legs almost as long as the first pair; tarsus 
swollen, about two-thirds as broad as long and one-third as long as the

eyes; expanded at the posterior end, at the anterior end continuous with 
a small triangular elevation upon which are situated six straight, slightly 
pectinate bristles, the two largest consisting of a pair situated near the 
posterior margin of the elevation; toward the middle of the elevation is 
situated a similar but smaller pair; just in front and just behind this 
pair is situated a single median bristle. A single pair of eyes present, 
rather large, situated two-thirds the distance from the dorsal groove to 
the lateral margin.
