the fourth leg the femur, patella, and proximal end of the tibia are 
fuscous; for the rest, the appendages are yellowish white; cephal- 
othorax and abdominal terga infuscate, the latter, in the posterior 
half of the abdomen, pale. 
Head plate bristly, wide, its width equal to the length of the 
protarsus of the palp, and much greater than its own length ; its 
anterior border straight ; ocular tubercle large, wider than long, 
and moderately high, the width between the eyes exceeding the 
diameter of an eye ; the tubercle furnished in front with two long, 
stout, forwardly directed bristles, behind which there are two rows 
of much shorter, finer bristles, passing between the eyes to the 
posterior part of the tubercle. 
Mandibles stout, the basal segment externally swollen, studded 
above and externally with long, stoutish bristles ; the stridulating 
ridges ten in number and strong; the inner surface of the two 
jaws bristly, the bristles on the basal half of the immovable jaw 
barbed on both sides, those forming the upper row on the mova- 
ble barbed along their posterior edges; the upper jaw armed 
internally with a series of four stout bristles; teeth, in addition 
to the short, stout, terminal fang, seven in number, of which the 
second is enormously large, and the sixth and seventh the small- 
est; in addition to these there is a single, moderately large, conical 
fang on the inner surface on a level with the area between the 
sixth and seventh teeth of the outer set; the movable jaw armed 
with three teeth, two large and conical, and one small one between 
them, but closer to the posterior; the flagellum consisting of a 
high, convexly margined, basal lamina; the filiform portion curv- 
ing abruptly backwards on a level with the first tooth and passing 
back to a simple point ona level with the posterior ends of the 
stridulating ridges. 
Rostrum, with its terminal portion bent slightly over, the upper 
edge of the inclined portion tricarinate, the lower lobe on each 
side ending in a long, feathery bristle, the usual feathery tuft or 
beard overhanging the aperture of the mouth. 
Palp: maxillary process moderately long ; femur distal strongly 
incrassate, hairy; patella moderately robust, about six times 
as long as broad, hairy, but armed below with a number of 
short, spiniform bristles; tibia and tarsus also armed below with 
short, spiniform bristles, tarsus immovably articulated to the tibia.
