Superfamily Argiopoidea 



by them in Dendryphantes. In the more restricted sense, Den- 

 dryphantes includes spiders of moderate size, rarely measuring 

 more than one fourth inch in length. The cephalothorax is 

 rather high and convex, widest in the thoracic part, highest at 

 the third row of eyes. The anterior eyes are large, slightly 

 separated; the second row is halfway between the other rows; 

 and the eye-space occupies two fifths of the length of the cepha- 

 lothorax. 



Even as restricted here the genus is a very large one, twenty 



species having been described from our fauna alone; as these 



resemble each other closely, it is often difficult to determine them. 



The two following are the most common species: 



Dendryphantes militaris (D. mil-i-ta'ris).— - The two sexes of 



this specie differ greatly in appearance. The male (Fig. 758) is

yellowish brown or bronze-brown marked with white. There is 

 a white band on each side of the cephalothorax below the eyes, 

 and extending back nearly to the abdomen, and there is a white 

 band around the edge of the abdomen; sometimes there are two 

 rows of white spots on the dorsum of the abdomen. The female 

 (Fig. 759) is brown or bronze-brown; the abdomen is marked with 

 a basal white band, four pairs of dorsal white spots, and, on the 

 sides, several oblique marks. The male measures one fourth inch 

 in length, the female, one third. 



This is a very common species, over a large part of our ter- 

 ritory.
