Superfamily Argiopoidea 



thorax is marked with a median light band, which is widest be- 

 tween the third row of eyes and the median furrow; in this wider 

 portion there are two dark longitudinal lines. On the basal half 

 of the abdomen there is a lanceolate stripe and behind this four 

 or five chevrons. The form of the epigynum is shown in Fig. 720 

 b. The length of the body is about one half inch. 



This is a very common species in the northeastern part of 

 the United States and in Canada; it is found under stones. 



Lycosa gulosa (L. gu-lo'sa). — The cephalothorax is dark 

 brown with a light gray stripe in the middle; this stripe is strongly 

 constricted in front of the median furrow and less markedly so 

 behind this furrow; it is widest in front of the first constriction, 

 and extends forward to the second row of eyes. The abdomen 

 is grayish brown above, with a darker lanceolate stripe on the 

 basal half; this stripe, however, is sometimes indistinct or wanting. 

 There is a black spot on each side near the base of the abdomen; 

 and usually a row of dark marks extend back on each side from 

 the basal spot to the hind end of the abdomen. The form of the 

 epigynum is shown in Fig. 720 g; and the palpus of the male in 

 Fig. 720 /;. The length of the body is about one half inch. 



This is a widely distributed species, its range covering the 

 greater part of the United States. It is common in forests, where 

 its brown and gray colours like those of dead leaves are protective. 



This species has been commonly known under the name of 

 Lycosa kochii; but this name, according to Chamberlin, should be 

 applied to another species, which is known only from the Far 

 West. 



Lycosa modesta (L. mo-des'ta). — The cephalothorax is dark 

 brown or nearly black with a light gray median band, which is as 

 wide as the space between the eyes of the third row; the margins 

 of this band are straight or slightly curved outward and converge 

 gradually backward; near each lateral margin of the carapace there 

 are two gray lines, which are often indistinctly separated. The 

 abdomen is brown, with a black lanceolate stripe on basal part 

 and black chevrons on the hinder part; there is also a black mark 

 on each side at the base, and usually a row of white spots on 

 each side behind, in which the chevrons terminate*. The male 

 measures one third inch in length; the female about one half inch. 



This species has been found in Maryland, District of Columbia 

 Pennsylvania, and Texas.
