Our largest Lycosa, much resembling in its large size and in colora- 

 tion the famous Tarcntula of southern Europe and its close allies. 

 Specimens from the Southwest often differ from the typical form in 

 having the venter in part pale as above described. 



"This spider has the same habits as L. fatijera, making deep excava- 

 tions in the ground. It is frequently found under stones, and possibly 

 it is in such places, nearer the surface, that the eggs are hatched. The 

 female carries her young on her back, presenting a hideous aspect, 

 being then apparently covered with animated warts. The little 

 monsters have the instinct, if the mother is much disturbed, to escape 

 and scatter in all directions. The male, not unfrequently of an 

 enormous size, is often found wandering in October and November in 

 Alabama, and sometimes enters houses" (Hentz), Concerning its 

 habits in New England, Emerton says: "This species digs a hole six 

 or eight inches deep, but is often found under stones or running in 

 fields and occasionally in houses all over New England." 



This species is common in Utah, where the males are frequently 

 seen wandering in the open or hiding under stones. The females dig 

 deep burrows which are sometimes surmounted with turrets, but not 

 so commonly so as in the case of fatijera, 



Lycosa coloradensis Banks, 1894. 

 (J. N. Y. Ent. Soc, p. 50.) 

 Female. — Tegument of cephalothorax reddish brown, densely clothed 

 with pubescence which nearly completely masks the ground color. A 

 median light band as wide anteriorly as the eye area, but abruptly nar- 

 rowed at dorsal groove to only half that width or less ; this median band 

 formed of brown-gray pubescence, often mixed anteriorly with darker 

 pubescence which obscures the distinctness of the band. Sides of cepha- 

 lothorax clothed with dark, brownish to grayish black pubescence, mixed 

 with gray like that of median band, the gray predominating, principally 

 arranged in wide radiating bands and becoming more abundant below, 

 where it forms on each side a marginal band which is widest anteriorly 

 where it nearly touches eye area. Chelicerm with tegument blackish or 

 reddish black, completely masked on upper half with dense pubescence 

 of rusty brown color, that of lower half dark and very sparse, paler
