than usual in Pardosa or Lycosa; anterior median eyes larger i^an the 

 lateral, of nearly same distance from each other as from the lateral 

 eyes ; clypeus narrow, the anterior lateral eyes at most their diameter 

 or but little more from the front margin of clypeus, the same distance 

 or considerably farther from the eyes of second row; eyes of second row 

 large, less than their diameter apart; quadrangle of posterior eyes 

 evidently wider behind than in front. Chelicera? as in Lycosa, the third 

 tooth of the inferior margin of the furrow usually reduced. Labium 

 distinctly longer than broad, the basal notch one-third its total length. 

 Posterior spinnerets short, scarcely or not at all longer than the 

 anterior. Epigynum with a distinct guide which is elevate and well 

 developed anteriorly as in Lycosa; the transverse arms of guide double, 

 being divided from their exterior ends mesally to a varying distance; 

 lateral furrows not widening anteriorly. (See figs, of PI. XVI.) 

 Male palpus with a scopus exterior in position presenting 

 two processes as in Lycosa; exposed area of lunate plate small; 

 conductor conspicuously produced above, usually into a horn-like 

 elevation of varying size; superior margin of inferior furrow present- 

 ing, more or less externally from its middle, a short and pointed, 

 basally wide, plate-like tenaculum which is curved downward distally; 

 a second, shorter tenaculum farther externally and anteriorly; auricula 

 of lectus very long, extending forward along conductor and attaining 

 or nearly attaining front margin of alveolus; embolus distinctly and 

 more or less angularly elbowed at base of auricula. (See figs, of 

 PI. XVI.)

Pars cephalica truncated in front, its sides moderately rounded and 

 sloping, the face rather high, its sides slanting in varying degrees, some- 

 times approaching the Pardosa type more and sometimes the Lycosa. 

 The quadrangle of posterior eyes in length averaging one-fourth the 

 length of the cephalothorax, being thus longer than in Lycosa. The legs 

 are long and moderately stout, inclining to be slender distally; the 

 anterior tarsi scopulate, at least laterally, the posterior tarsi setose
