A KATUN IDES AKANEIDES ORB1TELAK1.K. 85 



legs (broken), 5.5 mm ; fourth pair of legs (broken), 8 mm ; of part previous to 

 tibia, 3.2 mm ; diameter of palpi, 0.45""". 



This species differs from E. meekii in size, in the shape of the cephalo- 

 thorax, the stouter femora, and more sparsely armed tibue.. 



Florissant. One , No. 7583. 



3. EPEIRA DELITA. 



PI. 11, Fig. 6(3?). 



Cephalothorax rounded obovate, the cephalic and thoracic portions 

 completely blended, the sides uniformly rounded, the front very convex, 

 with no eyes that can be seen ; neither are the palpi preserved, the part 

 figured between the front legs having no relation to the spider ; it is judged 

 to be a male from the small size of the abdomen which is ovate, no larger than 

 the cephalothorax, largest in front of the middle, but here slightly narrower 

 than the cephalothorax, tapering slightly behind, and well rounded at the 

 extremity. The legs have very stout femora, those of the front pair taper- 

 ing in the middle, and both femora and tibia? and even the basal part of the 

 tarsi, but especially the tibiae, armed with very long, very distant, delicate, 

 divergent spinules considerably longer than, sometimes almost twice as long 

 as, the width of the tibiae; the basal joint of the tibiae tapers perceptibly. 

 The second pair of legs is represented too long in the plate, though it is 

 unusually long, not greatly falling behind the first pair and exceeding the 

 fourth in length nearly as much as that exceeds the third pair. 



Length of body, 4.75 mm ; of cephalothorax, 2.25"' ; width of same, 2 mm ; 

 length of abdomen. 2.5 mm ; of first pair of legs, 11.5 mra ; tibiae, 3.5 mra ; tarsi, 

 5 1 "" 1 ; second pair of legs, 9.8 mm ; tibiae, 3.25 mm ; tarsi, 4.2 mm ; third pair of 

 legs, 7.5 mm ; tibiae, 2 m '" : tarsi, 2.5""" ; fourth pair of legs, 9 mm ; tibia>, 2.25 mm ; 

 tarsi, 3.75 mm . 



This species agrees well with E. abscondita in size, but is readily dis- 

 tinguished both from it and from E. meekii in the uniform character of the 

 cephalothorax and the relative length of the legs.

Male. Cephalothorax globose, blackish, the dividing line between it 

 and the abdomen concealed by the overhanging quadrate front of the
