This species differs from C. agilis Banks in the more angular out- 

 line of the eye tubercle, in the greater depth of the median furrow 

 and in the proportion of the segments of the palpus, the femur, patella 

 and tibia being about equal in length. It is also larger and the color 

 markings do not agree with the description of that species. 



One specimen was taken after a heavy rain on a tree trunk on a 

 heavily wooded bank near Ithaca, N. Y., August, 1903. 



Caddo boopis, new species. 



Female. — Length, I mm. ; width of abdomen, .6 mm. ; width of eye tubercle 

 .48 mm. 



Dorsum of body reddish brown crossed by narrow light lines broken into spots 

 near the edge ; underside grayish brown. Eye tubercle very large and provided with 

 a broad furrow, dull yellow in the furrow and in front. Each eye with a broad, 

 black ring surrounded by yellowish. 



On the tergum two segments are visible on the cephalothorax and eight besides 

 the pygidium on the abdomen ; the ventral surface of the abdomen consists of seven 

 segments including the hypopygidium. 



Chelicerae whitish except the claws which are black. Legs and palpus dark 

 gray. Trochanter of palpus armed beneath with a large tubercle bearing two spines, 

 one large and one small ; two large spine-bearing tubercles at base of femur, one at 

 middle of the ventral side and near the tip on the inside ; one on the proximal half of 

 the patella and two on the tibia below. The outer side of the whole palpus nearly 

 naked, while the inner side is thickly clothed with strong hairs becoming more dense 

 on the tarsus. The tarsus is directed obliquely mesad. Ovipositor short, armed with 

 three transverse rows of setee before the fork ; each branch black at tip and armed
