The fakes are stout, their width exceeding that of the first 
row of eyes. They are nearly three times as long as the face, 
inclined forward, and diverging at the tips. The fangs are mod¬ 
erately long. 
The palpus has one strong spine on the distal end of the 
femur. 
The maxillse are parallel, and are enlarged and rounded at the 
extremities. The labium is a little more than f/i as long as the 
maxillae, longer than wide, rounded and slightly contracted at 
the tip. 
The sternum is as long as the anterior coxae, and about ]/i 
as wide as long. It projects between the anterior coxae, which 
are separated by the width of the labium. 
The relative length of the legs is 1, 3, 2, 4; the first and sec¬ 
ond are the stoutest, and are equal; the third is a little stoutei 
than the fourth. There are long spines on the femoral, patellary, 
tibial and metatarsal joints of the four pairs, those on the tibiae 
and metatarsi of the third and fourth being in both superior and 
inferior rows, and those on the metatarsi of the fourth extending 
to the base.

bands, a central one beginning in the middle of the ocular area, 
and one on each side beginning under the dorsal eye, all extend¬
