straight anteriorly and pointed posteriorly. Anterior spinnerets long- 

 est. Legs short and thick, 1 ventral spine on tibia I, 2 on tibia II, 

 3 pairs on tibia? Ill and lY ; metatarsus IV shorter than patella and 

 tibia combined; leg IV to cephalothorax as 2.-4 : 1. 



Trochosa sublata (Montg.). 



Lycosa sublata Montgomery, 1902. 



( 9 , type, Point Pleasant, New Jersey.) 



Eyes. — First row slightly broader than the second, straight, nearer 

 the second row than to the clypeal margin, middle eyes slightly larger. 

 Eyes of second row largest, their diameter apart. Third row slightly 

 broader than the first, its eyes more than twice their diameter behind 

 the second row. Quadrilateral of the posterior ej'es longer than broad. 

 Dorsal eye area to length of cephalothorax as 1 : 5. 



Form. — Cephalothorax in front somewhat roimded and more than 

 one-half its greatest transverse diameter, highest at the middle ; head 

 low and its sides obhcjue. Chelicera with 3 pairs of teeth, their length 

 greater than the width of the clypeus and c^uite 3 times the height of 

 the head in front. Labium longer than wide, truncated apically, not 

 one-half the length of the maxillae. Legs thick, metatarsus IV shorter 

 than patella and tibia combined. Length of leg IV to cephalothorax 

 as 3.6 : 1. 



Genus PIRATA SundevaU, 1S33. 



The main combinations of characters of this genus are : The first eye 

 row is fully as broad as the second (slightly shorter in elegans and 

 nigromaculatus) ; the length of the posterior spinnerets is quite 1.5 

 times that of the anterior, frecjuently twice; the metatarsus IV is in 

 both sexes shorter than the patella and tibia combined by only one- 

 third the length of the patella (one-half in marxi); the inferior tarsal 

 claw is toothed (except in marxi) ; the sides of the head are oblique 

 (except in elegans and the c? of liher) ; the chelicera are weak, rather 

 straight anteriorly, their length not more, usually less, than twice the 

 height of the head in front; the labium is large and longer than broad. 

 The chelicera have 2 or 3 teeth on the posterior border. The eyes of 

 the second row are less than L5 times their diameter apart. The cepha- 

 lothorax is highest behind the middle, or in the cephalic region (elegans). 

 Tibia I has 3 ventral pairs of spines. The length of leg TV to the cepha- 

 lothorax varies from 3.3 : 1 to 4.6 : 1 ; the legs have generally long spines 

 and frec^uently fine long hairs. 



It is somewhat doubtful whether this genus is a homogeneous one; 

 marxi approaches Trochosa, and elegans, Lycosa. There are also some
