rower than that of the caput, the thoracic plate being obtusely 

 rounded behind. The quadrangle of the eyes is one-third wider 

 than long, is equally wide in front and behind and occupies two- 

 fifths of the length of the cephalothorax. The anterior eyes are 

 large and form a straight row ; they are a little separated from 

 each other, and the middle are twice as large as the lateral. 

 The second row is a little nearer the first than the third. The 

 third r6w is narrower than the cephalothorax. 



The abdomen is long and rather slender, narrowing 

 slightly behind. The falces are moderately long; they are 

 stout, and obliquely directed forward, and have several teeth on 

 the inner edge of each. The maxillge are long and heavy. 

 The labium is as wide as long, and is half as long as tlie max- 

 illae. The sternum is oval. 



The upper surface of the cephalothorax seems to have been 

 covered with white hairs. Orange-colored hairs cover the pos- 

 terior slope and the upper sides, and grow thick and long 

 around the eyes of the first row. The lower sides have a wide 

 band of white hairs, and there is a black line around the lower 

 edge. The integument of the upper surface is black, with iri- 

 descent reflections. Just behind the post-ocular depression is 

 a large spot of light brown, which becomes conspicuous when 

 the hairs are rubbed off. 



The integument of the abdomen is fawn color, with two 

 parallel, longitudinal black stripes. The fawn-colored part is 

 covered with white, and the black part with orange hairs. 

 There are a good manj^ long, white hairs which project for- 

 ward around the anterior end of the abdomen. The falces are 

 dark reddish-brown, overhung with long, white hairs from the 

 clypeus and having themselves a thin covering of white hairs 

 and short fringes of brownish-yellow hairs on their inner 

 edges. The first leg is dark reddi.sh-brown, with one spine on 

 the femur, one on the patella and a double row of heavy spines 

 on the under surface of the tibia. The other legs are yellowish- 

 brown, much lighter in tint than the first, none of them being 

 very hairy. The mouth parts are almost black and are cov- 

 ered with brown hairs. The venter is brown, with white hairs ;
