June, 1904] Banks: Nearctic Spiders. 113 



lowish, with a faint brown stripe each ^icie. Venter pale, with a white line each side ; 

 sternum and legs pale yellowish, unmarked. Cephalothorax longer (proportionately) 

 than in T. caudatus, high till near abdomen, then suddenly falls oft". Abdomen trun- 

 cate at base, about twice as long as broad, but little broader in middle, pointed behind, 

 slightly, although distinctly elevated in a small cone in female, in male simply high 

 at tip. Legs slender, but rather short, very hairy, with but few spines, most promi- 

 nent on metatarsi I and II. Length, male, 2.4 mm.; female, 3 mm. 



Several specimens taken near Washington,. D. C. in Ma)', under 

 rubbish on the ground. Distinct by its much smaller size as well as 

 other characters. One specimen has the sides of cephalothorax and 

 abdomen dark-brown. 



Apollophanes texana, new species. 



Cephalothorax yellowish, slightly mottled with brown on sides, and two ap- 

 proximate dark marks on base of cephalic part, clypeus and mandibles pointed with 

 brown ; legs pale yellow and pointed and spotted with brown, especially on femora 

 and tibije ; these markings faintly indicate a subapical band on femora and a basal 

 band on tibiae. Sternum and venter pale. Abdomen pale, with a basal brown spear- 

 mark, and behind two more or less connected rows of blackish spots. Cephalo- 

 thorax but little longer than broad, scarcely noticeably so. Abdomen about twice 

 as long as broad. Legs long and slender ; leg I a little longer that IV, tibia I with 

 3-3 spines beneath, the last short and apical ; sternum as broad as long ; hind cox?e 

 separate. Eyes of posterior row strongly recurved, and about equidistant ; A. S. E. 

 a trifle closer to P. M. E. than to A. M. E. Length, 9 6 mm., $ 5.2 mm. 



One pair from San Antonio, Texas. Differs from the two Mex- 

 ican species in larger palpal organ, and less slender process at tip of 

 tibia, and the style is longer. 



Scaptocosa, new genus. 



Differs from Lycosa and Trochosa, as well as our other Lycosids in lacking 

 spines aboveon tibite III and IV, either at base or middle ; these joints being clothed 

 above with long hair. Head high and large, sides sloping ; anterior eye-row scarcely 

 wider than second row ; eyes of second row scarcely diameter apart. Tibia I 

 densely hairy below, with 2,~3 spines, tibise IV with 2 short spines on each side. 

 Spinnerets all short, subequal. 



Type. — Lycosa arenicola Scudder {nidi/ex Marx). 

 Also contains Z. viissouriensis Banks {^domifex Hanc). This 

 species has nothing to do with L. fatifera Hentz, which Hentz com- 

 pares io L. carolinensis 3.nd says is from Massachusetts. L. fatifera 

 can thus only be Z. tigrina McCook {imlpina Emer. , obloii'^a and 

 exitiosa Bks. ). 



AUocosa, new genus. 



Tibiae III and IV with a basal spine above; tibia I, with t,-t, short spines 

 below ; eyes of second row less than diameter apart ; first row plainly wider than
