Body nearly twice as long as broad, broadest at shoulders, broadly 
rounded at tip. Cephalothorax with a pair of feathered bristles in front, 
and a pair of broad scales, three similar scales on each side, and a long 
feathered bristle near each hind angle, four scales forming a square in 
middle. On dorsum of abdomen are four rows each of three broad scales, 
and four rather more slender ones at the tip. The basal joints of the legs 
have each one or two scales and one or two feathered bristles; the bristles 
near the tips of legs are more simple. The palpus is moderately heavy; 
the femur is almost angularly swollen on outer side, with a long plumose 
bristle above on middle; the next joint is fully twice as broad as long, 
with a long plumose hair near outer edge; the third joint has a simple 
hair on inner side ; the fourth ends in a large claw, with a row of hairs on 
inner side; the fifth, or papilla, bears two long curved claws, and a long 
comb below, with a simple bristle arising near base of comb. The 
beak has a pair of long plumose bristles above. Leg i ends in two long 
bristles, the longer is twice as long as the tarsus.
