terior lateral angles are distinct though obtuse, the hind margin being some- 
what concave each side the median lobe ; and the margins are hairy as in 
the thorax. 
The upper antennae are nearly as long as the pedicel of the lower. The 
flagellum consists of 11 to 13 joints, the two terminal together about as 
long as the preceding one. The three joints preceding the last bear, each 
at its anterior internal angle, a large olfactory club about at long as the 
eighth joint of the flagellum. 
The lower antennae extend backward about to the base of the abdomen. 
The last joint of the pedicel is as long as the two preceding. The flagellum 
contains about 60 joints in the female and 90 in the male. 
The palpus of the mandible is small, three-jointed, the first joint cla- 
vate, with three spines on the distal half of the posterior margin and one or 
two at tip. The second joint is about twice as long as wide, slightly con- 
cave in front and with a distinct median angle behind. There are two or 
three scattered hairs on the basal half of the posterior margin, and many 
long plumose hairs, shortening distally, on the terminal half. The third 
joint is ovoid, tapering, very broadly rounded in front and distinctly con- 
cave behind. The concave posterior margin bears a row of long plumose 
hairs, regularly lengthening toward the tip, and a sub-marginal row of 
shorter hairs on the side of the joint. The basal joint of the palpus of the 
maxilliped is very short, transverse, about thrice as broad as long, with 
outer margin perpendicular to terminal. The second joint is a little broader 
than long, rounded slightly without, very broadly within, and plentifully 
ciliate on both edges. 
The third joint is about two-thirds as long as second, broadly and reg- 
ularly rounded within, narrowed about one-third at tip ; the fourth clavate, 
incurved, as long as second, at tip about half as wide as long ; the fifth 
about half as wide and long as fourth, incurved, obtuse. All the joints bear 
long marginal hairs. 
The first pair of feet in the male are strongly sub-chelate ) the propodus 
a little more than two-thirds as wide as long, the palmar margin straight, 
with one strong tooth at base and another at middle. The posterior margin 
is only about one-fifth the palmar, and perpendicular to it. The dactyl is 
strong, curved, serrate behind with about seven distinct teeth. The terminal 
claw is strong, acute and curved. Both margins of the propodus and the 
front of the dactyl are hairy : a cluster of longer hairs is seen near base of 
claw of dactyl. 
The propodus of the female is a little narrower and the palmar margin 
is somewhat concave. The tooth at the middle of the palmar margin is 
smaller, but quite distinct. 
The basal abdominal plate beneath in the female is obtusely triangular, 
about half as long as the basal part of the next plate behind. The first pair 
o i- genital plates in the male are long and narrow, the terminal joint truncate, 
strongly excurved beyond the middle, and bordered posteriorly by about 
six long bristles a third as long as the joint. 
In the second pair of plates the basal joint (pedicel) is twice as long as
