Superfamily Argiopoidea 



genus is placed in two divisions of the table on page 333. This 

 is a widely distributed genus; but it includes only a few species, 

 of which only one has been found in the United States. The 

 males possess stridulating organs. (Fig. 325, p. 333.) 



Asagena americana (A. a-mer-i-ca'na). — The cephalothorax 

 is dark reddish brown; the legs, yellowish brown. In the male 

 the legs bear two rows of teeth under each femur. The abdomen 

 is dark brown with two white spots across the middle (Fig. 369); 

 these white spots are sometimes indistinct. The length of the 

 body is about one sixth inch. This spider is usually found under 

 stones. 



Genus ENOPLOGNATHA (En-o-plog'na-tha) 



The lateral eyes of each side are contiguous; the lower margin 

 of the furrow of the chelicerae is toothed, and in the males the 

 chelicerae are furnished with long teeth. The males possess 



stridulating organs. This is a very large 

 and widely distributed genus of which 

 three species occur in the United States. 

 Enoplognatha marmorata (E. mar- 

 mo-ra'ta). — The cephalothorax and 

 legs are yellowish brown; the legs are 

 covered with fine hair. The abdomen 

 is whitish, marked with dark spots.'and 

 lines; there is usually an oblong dark 

 spot covering the greater part of the 

 dorsal aspect, the middle of which is 

 lighter with a central dark stripe (Fig. 

 370). "In some individuals the dark markings are broken up 

 into four pairs of black spots partly connected with a middle line " 

 (Fig. 371). " It lives under stones and leaves at all seasons and, 

 occasionally on bushes" (Emerton). The length of the body is 

 about one fourth inch. It occurs over a large part of the United 

 States. 



Enoplognatha tecta is a closely allied species described from 

 Colorado. The abdomen is brown streaked with black on the 

 sides, with a median dark stripe above, and with two little round 

 white flecks on the side below. 



Enoplognatha rugosa (E. ru-go'sa). — This species was re- 

 cently discovered by Emerton in New Hampshire. It is about 



364
