 Philodromoides, gen. nov. 



Cephalothorax low, about as wide as long; head region much narrowed 

 and slightly elevated. Abdomen fully twice as long as wide, very 

 little wider behind than at the base; somewhat pointed at the end; 

 the base projects a short distance over the cephalothorax, and is 

 distinctly notched on the upper side. The sternum and labium are 

 about as in Philodromus. All eyes approximately equal in size; the 

 anterior row much the shorter and slightly recurved; median eyes 

 of this row farther from each other than from«the side eyes. Pos- 

 terior row also recurved; side eyes of this row on larger tubercles 

 than any of the others; median eyes farther from each other than 

 from the side eyes. Ocular quadrangle considerably wider behind; 

 about as wide as long. Clypeus wider than space between anterior 

 median eyes, but not as wide as space between posterior median 

 eyes; obliquely directed forward and downward. Legs long and 

 slender, the second pair longest, the third shortest; the relative 

 lengths are, in their order, second pair, first pair, fourth pair, third 

 pair. The tibige of the first and second pairs are set beneath with 

 ten or twelve stout spines arranged in two rows, and the metatarsi 

 are similarly armed with half that number. Weaker spines like- 

 wise occur on the other two pairs of legs and on the pedipalps. 

 Philodromoides prataria, sp. nov. (fig. 10). 



Female. — Length, 6 mm. ; length and width of cephalothorax, 2 mm.; 

 width of abdomen, 2 mm. Other characters as given in the generic 

 description. A very few short, bristle-like hairs scattered about 

 among the spines on the outer joints of the legs and on the chelicerae 

 and the pedipalps; thickest on the tarsi of the latter. 

 Coloration.— Abdomen plain brown above, mottled and streaked with 

 a lighter shade. The four muscle impressions are quite distinct. 

 Cephalothorax rusty brown, lighter at the sides and just back of 

 the head region. Streaks marked by depressed lines radiate from 

 the dorsal groove. The sternum is pale yellow or alnjost white. 

 The abdomen is lighter beneath than above, and there is a less 

 mottled central region, set off by a row of indistinct dots on either
